Title: Reel Mower Cutting Bar

Description:
FIELD 
     The present disclosure relates generally to a reel mower, and more particularly to a reel mower including a reel and a cutting bar that are moveable relative to one another. 
     BACKGROUND 
     This section provides background information related to the present disclosure and is not necessarily prior art. 
     Reel mowers are typically constructed with a set of four to ten heavy steel blades fixed in a cylindrical form and rotated about the axis of the cylinder parallel to the ground and perpendicular to the direction of travel of the mower. The blades are generally twisted in a helical form, and positioned to graze the leading edge of a horizontal cutter bar or blade suspended at the desired cutting distance above the ground. As the mower is pushed forward, the blades of grass are swept against the horizontal blade and sheared between the horizontal blade and the passing helical blade. In such situations, it is common for objects such as sticks, pinecones, acorns, and the like to become lodged between the helical blades and the horizontal blade, thus inhibiting the desired cutting operation of the mower. 
     SUMMARY 
     This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features. 
     One aspect of the disclosure provides a mower. The mower includes a frame, a reel, and a blade subassembly. The reel is supported by the frame for rotation about a first axis extending in a first direction. The blade subassembly is supported by the frame and extends along a second axis extending in the first direction. At least one of the reel or the blade subassembly is configured to move relative to the other of the at least one of the reel or the blade subassembly in a second direction transverse to the first direction between an engaged position and a disengaged position. The release mechanism includes (i) a first mechanism coupled to one of the frame or the blade subassembly, and (ii) a second mechanism coupled to the other of the frame or the blade subassembly. The first mechanism is releasably coupled to the second mechanism in the engaged position. 
     Implementations of this aspect of the disclosure may include one or more of the following optional features. In some implementations, the first mechanism includes a protrusion, and the second mechanism includes a detent configured to releasably receive the protrusion in the engaged position. The protrusion may extend a distance from the one of the blade subassembly or the frame in the first direction. The protrusion may be coupled to the one of the frame or the blade subassembly to adjust the distance. The first mechanism may include a housing and a biasing member. The housing may define an aperture. The biasing member and the protrusion may be at least partially disposed within the aperture. The first mechanism may include a screw adjustably disposed within the aperture. The biasing member may include a first end engaging the screw, and a second end engaging the protrusion. 
     In some implementations, the first axis is parallel to the second axis in the engaged position and in the disengaged position. 
     In some implementations, the mower includes a biasing member coupled to the at least one of the reel or the blade subassembly and configured to move the at least one of the reel or the blade subassembly from the disengaged position to the engaged position. 
     In some implementations, the blade subassembly is configured to pivot relative to the frame. 
     In some implementations, the mower includes an arm pivotally coupled to the frame and the blade subassembly. 
     Another aspect of the disclosure provides a mower. The mower includes a frame, a reel, a blade subassembly, and a release mechanism. The reel is supported by the frame and configured to rotate about a first axis extending in a first direction. The blade subassembly is supported by the frame and configured to move relative to the reel between a first orientation and a second orientation. The blade subassembly is spaced from the reel by (i) a first distance in the first orientation and (ii) a second distance in the second orientation. The release mechanism includes (x) a first mechanism coupled to one of the frame or the blade subassembly, and (y) a second mechanism coupled to the other of the frame or the blade subassembly, wherein the first mechanism is releasably coupled to the second mechanism in the first orientation. 
     Implementations of this aspect of the disclosure may include one or more of the following optional features. In some implementations, the first mechanism includes a protrusion, and the second mechanism includes a detent configured to releasably receive the protrusion in the first orientation. The protrusion may extend a distance from the one of the blade subassembly or the frame in the first direction. The protrusion may be coupled to the one of the frame or the blade subassembly to adjust the distance. The first mechanism may include a housing and a biasing member. The housing may define an aperture. The biasing member and the protrusion may be at least partially disposed within the aperture. The first mechanism may include a screw adjustably disposed within the aperture. The biasing member may include a first end engaging the screw, and a second end engaging the protrusion. 
     In some implementations, the first axis is parallel to the blade in the first orientation and in the second orientation. 
     In some implementations, the mower includes a biasing member coupled to the blade subassembly and configured to move the blade subassembly from the second orientation to the first orientation. 
     In some implementations, the blade subassembly is configured to pivot relative to the frame. 
     In some implementations, the mower includes an arm pivotally coupled to the frame and the blade subassembly. 
     Yet another aspect of the present disclosure provides a mower. The mower includes a frame, a blade assembly, and a reel. The blade assembly is supported by the frame for rotation about a first axis between an engaged position and a disengaged position. The reel is supported by the frame for rotation about a second axis. The reel defines an outer diameter relative to the second axis and engages the blade assembly at a contact location in the engaged position. The outer diameter defines a tangent at the contact location. A force in a direction substantially parallel to the tangent is operable to produce a first torque in a first direction about the first axis when the blade assembly is in the engaged position. The weight of the blade assembly is operable to produce a second torque in a second direction about the first axis when the blade assembly is in the engaged position. 
     Yet a further aspect of the present disclosure provides a mower. The mower includes a frame, a blade assembly, and a reel. The blade assembly is supported by the frame for rotation about a first axis between an engaged position and a disengaged position. The reel is supported by the frame for rotation about a second axis. The reel defines an outer diameter relative to the second axis and engages the blade assembly at a contact location in the engaged position. The second axis is disposed above the contact location and below the first axis. 
     Another aspect of the present disclosure provides a mower. The mower includes a frame, a reel, and a blade assembly. The reel is supported by the frame for rotation about a first axis. The reel defines an outer diameter relative to the first axis. The blade assembly is supported by the frame for movement between an engaged position and a disengaged position. The blade assembly includes an edge configured to engage the reel at a contact location in the engaged position. In the disengaged position, the edge is disposed above the contact location. 
     Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

     DETAILED DESCRIPTION 
     Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure. 
     Referring to  FIGS. 1 and 2 , in some implementations, a mower  10  includes a frame assembly  14 , one or more wheels  12 , and a cutter assembly  16 . As will be described in more detail below, the mower  10 , including the cutter assembly  16 , may be designed to facilitate the cutting of grass, weeds, and the like during use. In this regard, while the mower  10  is generally shown and described herein as being a manual reel mower, it will be appreciated that the mower  10  may include other forms (e.g., motorized reel mower) within the scope of the present disclosure. 
     As illustrated in  FIG. 2 , the frame assembly  14  may include a handle  18  and a chassis  20  coupled to the handle  18  such that a force applied to the handle  18  by, for example, a user is transmitted to the chassis  20 . In some implementations, the handle  18  is pivotally coupled to the chassis  20  such that an orientation of the handle  18  relative to the chassis  20  can be changed or otherwise adjusted by the user. The wheel(s)  12  may be coupled to one or both of the frame assembly  14  or the chassis  20  such that, upon application of a force on the frame assembly  14  (e.g., by a user, a motor, etc.), a user is able to roll and/or steer the mower  10  on the wheel(s)  12  along a ground surface. 
     The chassis  20  may include a pair of opposed side panels  22  and one or more support members  23  extending between the side panels  22 . In this regard, each support member  23  may include two ends, each coupled to one or both of the chassis  20  (e.g., one of the side panels  22 ). The support members  23  are configured to provide structural support and rigidity to the frame assembly  14  of the mower  10 . As illustrated in  FIGS. 3A-4A , one or both of the side panels  22  may include flange  25  extending inwardly toward the other of the side panels  22 . As will be described in more detail below, during use of the mower  10 , the flange  25  may engage a portion of the cutter assembly  16 . 
     With reference to  FIGS. 3A-4B , the cutter assembly  16  may include a reel  24  and a blade subassembly  30 . As will be described in more detail below, during use of the mower  10 , the reel  24  may engage the blade subassembly  30  to cut a blade of grass or other items disposed between the reel  24  and the blade subassembly  30 . 
     The reel  24  is supported by the frame assembly  14  for rotation about a first axis A 1  extending in a first direction. The reel  24  may include an axle  26  and one or more reel blades  28 . The axle  26  extends in the first direction along, and about, the first axis A 1 . As illustrated in  FIG. 1 , the axle  26  has a proximal end  32 - 1  and an opposed distal end  32 - 2 . Each of the proximal and distal ends  32 - 1 ,  32 - 2  is coupled to the frame assembly  14  such that the axle  26  may rotate about the first axis A 1 . In this regard, the axle  26  is configured to rotate about the first axis A 1  as the wheels  12  move along the ground surface. For example, as the wheels  12  rotate in a clockwise or counterclockwise direction, the axle  26  may rotate about the first axis A 1  in the clockwise or counterclockwise direction. In some implementations, the mower  10  includes a chain  33 , or other suitable drive mechanism (e.g., gears), that is coupled to the wheels  12  and the reel  24  to cause the reel  24  to rotate about the axis A 1  upon rotation of the wheels  12 . 
     The reel blades  28  may be coupled to the axle  26 . In particular, the reel blades  28  may be coupled to, and/or otherwise form, an outer surface of the axle  26  and extend in a helical configuration along, and about, the length of the axle  26 . The reel blades  28  rotate about the first axis A 1  as the axle rotates about the first axis A 1 . The reel blades  28  are configured to position the blades of grass between the reel blades  28  and the blade subassembly  30 . 
     The blade subassembly  30  may include a blade  34 , a blade bar  36 , one or more biasing members  38 , one or more arms  44 , a release mechanism  45 , and a handle  50 . The blade  34  extends along a second axis A 2  extending in the first direction. In this regard, in some examples, the first axis A 1  of the reel  24  is substantially parallel (e.g., +/−5 degrees) to the second axis A 2  of the blade  34 . The blade  34  may include a sharp surface that faces and/or engages the reel  24 , such that, upon rotation of the reel  24 , the blade  34  and the reel  24  cooperate to shear the blades of grass disposed between the blade  34  and the reel blades  28 . 
     The handle  50  may be coupled to the blade bar  36  to allow the user to selectively move the blade subassembly  30  between an engaged position (e.g.,  FIGS. 3A and 3B ), in which the blade  34  engages, or disposed a first distance from the reel blades  28 , and a disengaged position (e.g.,  FIGS. 4A and 4B ), in which the blade  34  is disengaged from, or disposed a second distance, different (e.g., greater) than the first distance, from the reel blades  28 . 
     In some implementations, the blade subassembly  30  is configured to pivot relative to the frame assembly  14 . In this regard, the blade  34  may include opposed proximal and distal ends  40 - 1 ,  40 - 2 , and the arms  44  may each include opposed first and second ends  44 - 1 ,  44 - 2 . The proximal and distal ends  40 - 1 ,  40 - 2  of the blade  34  may each be coupled to one of the arms  44 . In particular, the first end  44 - 1  may be pivotally coupled to one end  40 - 1 ,  40 - 2  of the blade  34 , and the second end  44 - 2  may be pivotally coupled to the frame assembly  14  (e.g., one of the side panels  22 ). In some implementations, the arms  44  are pivotally coupled to the frame assembly  14  and the blade  34  for rotation about a third axis A 3  extending in the first direction. The third axis A 3  may be parallel to, and/or aligned with, the first axis A 1  of the reel  24  and to the second axis A 2  of the blade  34 . In some implementations, the third axis A 3  is offset from the first axis A 1  of the reel  24  and/or the second axis A 2  of the blade  34  in a direction transverse to the first direction. During use of the mower  10 , the arms  44  can rotate about the third axis A 3 . In particular, the arms  44  can rotate about the third axis A 3  to allow the blade  34  to move (e.g., pivot) during use (e.g., during rotation of the reel  24 ) between the engaged position and the disengaged position, as described in more detail below. In particular, movement of the blade  34  may include pivoting about the third axis A 3  between the engaged position and disengaged position. 
     In the examples described herein, the first axis A 1  of the reel  24  remains static and the second axis A 2  of the blade  34  moves (e.g., translates, pivots, etc.) relative to the first axis A 1  of the reel  24  in a second direction transverse to the first direction. In some implementations, however, the second axis A 2  of the blade  34  remains static and the first axis A 1  of the reel  24  moves (e.g., translates, pivots, etc.) relative to the second axis A 2  of the blade  34  in the second direction transverse to the first direction. Additionally, in some examples, the first axis A 1  of the reel  24  moves (e.g., translates, pivots, etc.) relative to the second axis A 2  of the blade  34  in the second direction and the second axis A 2  of the blade  34  also moves (e.g., translates, pivots, etc.) relative to the first axis A 1  of the reel  24  in the second direction. The first axis A 1  of the reel  24  may be parallel to the second axis A 2  of the blade  34  in both of the engaged position and disengaged position. 
     The first axis A 1  of the mower  10  may be spaced from the second axis A 2  by a first distance in a first orientation (e.g.,  FIGS. 3A and 3B ). In particular, the first axis A 1  of the reel  24  may be spaced from the second axis A 2  of the blade  34  by the first distance while the blade  34  is in the first orientation (e.g., engaged position). The first axis A 1  of the mower  10  may be spaced from the second axis A 2  by a second distance in a second orientation (e.g.,  FIGS. 4A and 4B ). That is, the first axis A 1  of the reel  24  may be spaced from the second axis A 2  of the blade  34  by the second distance while the blade  34  is in the second orientation (e.g., disengaged position). 
     As previously described, at least one of the reel  24  or the blade  34  is configured to move relative to the other of the reel  24  or the blade  34  between the first orientation and the second orientation, such that the first axis A 1  is spaced from the second axis A 2  by the second distance in the second orientation. The second distance (e.g.,  FIGS. 3A and 3B ) may be greater than the first distance defined by the first orientation (e.g.,  FIGS. 4A and 4B ). That is, when the blade  34  moves relative to the reel  24  from the first orientation (e.g., engaged position) to the second orientation (e.g., disengaged position) the distance between the blade  34  and the reel  24  may increase from the first distance to the second distance. 
     In some implementations, the blade  34  ( i ) engages the reel  24  in the engaged position and (ii) defines a void V ( FIG. 6 ) relative to the reel  24  in the disengaged position. In particular, in the engaged position, the blade  34  is configured to cut blades of grass or other items disposed between the reel blades  28  and the blade  34 . In the disengaged position, the void V between the reel  24  and the blade  34  is such that the blades of grass or other items disposed between the reel blades  28  and the blade  34  are not cut by the blade  34 . As illustrated in  FIGS. 3A, 3B, and 4B , in some implementations, the blade subassembly  30  further includes one or more projections  51 . For example, a projection  51  may extend from one or both of the arms  44  toward one of the side panels  22  in the first orientation (e.g.,  FIGS. 3A and 3B ). During use of the mower  10 , the projection(s)  51  may engage the flange  25  to inhibit movement (e.g., rotation) of the blade subassembly  30  about the third axis A 3  in a first direction (e.g., clockwise), while allowing movement (e.g., rotation) of the blade subassembly  30  about the third axis A 3  in a second direction (e.g., counterclockwise) opposite the first direction. In this way, the flange  25  and the projection  51  ensure that the blade subassembly  30  moves to a predetermined position upon moving from the second orientation to the first orientation. 
     The one or more biasing members  38  may be coupled to the frame assembly  14  and the blade subassembly  30 . As will be describe in more detail below, during use of the mower  10 , the biasing member  38  may provide a biasing force upon at least one of the frame assembly  14  or the blade subassembly  30  in order to bias the blade subassembly  30  in to the first orientation (e.g.,  FIGS. 3A and 3B ). In particular, the biasing force from the one or more biasing members  38  biases the blade  34  into the engaged position. When the blade  34  moves to the disengaged position, the biasing force of the biasing member  38  urges the blade  34  to the engaged position. While the biasing member  38  is generally shown and described herein as being coupled to and applying the force to the blade  34 , it will be appreciated that the biasing member  38  may additionally and/or alternatively be coupled to and apply the force to the reel  24  in order to move (e.g., pivot, translate, etc.) the reel  24  in the manner previously described. In some examples, the biasing member  38  is positioned between second end  44 - 2  of the arm  44  and the frame assembly  14 . 
     In some implementations, the biasing member  38  includes a spring (e.g., a torsion spring, leaf spring, etc.) that biases the blade  34  into the engaged position. In some implementations, the blade subassembly  30  may be formed without the biasing members  38 , such that blade subassembly  30 , including the blade  34 , pivots from the disengaged position (e.g.,  FIGS. 4A and 4B ), in which the blade  34  is disengaged from the reel blades  28 , to the engaged position (e.g.,  FIGS. 3A and 3B ), in which the blade  34  engages the reel blades  28 , by the force of gravity or by the application of a force on the blade subassembly (e.g., on the handle  50 ) by the user. 
     Referring now to  FIG. 5 , in some implementations, the release mechanism  45  may include one or more first mechanisms  46  coupled to one of the blade subassembly  30  or the frame assembly  14  (e.g., the side panels  22 ), and one or more second mechanisms  48  coupled to the other of the blade subassembly  30  or the frame assembly  14 . For example, the first mechanism(s)  46  may be coupled to the arm(s)  44 , and the second mechanism(s)  48  may be coupled to the side panel(s)  22 . 
     The first mechanism  46  may include a housing a nut  52 , a housing  54 , a set screw  56 , a biasing member  58 , and a protrusion  60 . As illustrated in  FIG. 5 , the nut  52  may be secured to one of the side panels  22  and define a threaded aperture  62 , The housing  54  may include a proximal end  64 , a distal end  66 , a threaded outer surface  68 , and an aperture  70  extending between (e.g., through) the proximal and distal ends  64 ,  66 . In some implementations, the aperture  70  is threaded between the proximal and distal ends  64 ,  66 . As illustrated in  FIG. 5 , the aperture  70  may define an opening  72  in the proximal end  64  and an opening  74  in the distal end  66 . In some implementations, the opening  72  defines a first cross-sectional dimension (e.g., diameter) and the opening  74  and/or the remainder of the aperture  70  defines a second cross-sectional dimension (e.g., diameter) that is larger than the first cross-sectional dimension defined by the opening  72 , such that the housing  54  defines an inwardly-extending lip  76  proximate the opening  72 . 
     The set screw  56  may be disposed within the aperture  70 . In some implementations, the set screw  56  defines a threaded outer surface that is threadably-coupled to a threaded inner surface defining the aperture  70 . In this regard, the location of the set screw  56  between the proximal and distal ends  64 ,  66  may be changed by rotating and threading the set screw  56  within the aperture  70 . It will be appreciated, however, that in other implementations, the location of the set screw  56  within the aperture  70  may be determined and/or changed by other techniques, such as a press-fit configuration. 
     The biasing member  58  may include a helical compression spring having a proximal end  75  and a distal end  77 . The protrusion  60  may include a ball bearing defining a cross-sectional dimension (e.g., diameter) that is smaller than the cross-sectional dimension defined by the opening  74  and larger than the cross-sectional dimension defined by the opening  72 . 
     In the assembled configuration, the biasing member  58  and the protrusion  60  may be disposed within the aperture  70  such that the proximal end  75  of the biasing member  58  engages the protrusion  60 , and the distal end  77  of the biasing member  58  engages the set screw  56 . The threaded surface  68  of the housing  54  may be threadably-disposed within the threaded aperture  62  of the nut  52 , such that the protrusion  60  extends a distance X 1  from the one of the arm  44  or the frame assembly  14  (e.g., side panel  22 ) in a direction parallel to the axis A 2 . As will be explained in more detail below, in some implementations, the protrusion  60  includes a convex end  78  that engages the second mechanism  48  in the first orientation (e.g.,  FIGS. 3A and 3B ). In this regard, the first mechanism  46  may engage the second mechanism  48  to constrain and allow movement of the blade subassembly  30  relative to the chassis  20 . In some implementations, a user may adjust the distance X 1  by threading the housing  54  within the nut  52 . Similarly, by threading the set screw  56  within the aperture  70 , the user may adjust a force applied by the biasing member  58  on the protrusion  60  in a direction parallel to the axis A 2 . 
     The second mechanism  48  may include a nut  80  and a bolt  82 . As illustrated in  FIG. 5 , the nut  80  may be secured to the blade  34  and define a threaded aperture  84 . The bolt  82  may include a threaded outer surface  86  threadably-disposed within the threaded aperture  84  of the nut  80 , such that the bolt  82  extends a distance X 2  from the arm  44  in a direction parallel to the axis A 2 . In some implementations, the second mechanism  48  is configured to receive the first mechanism  46 . For example, the bolt  82  may include a detent (e.g., a concave end  48 - 1 ) that faces the convex end  78  of the protrusion  60 . The second mechanism  48  may extend in in a direction parallel to the axis A 2  through the arm  44 , the blade bar  36 , and the nut  52 . In this example, the concave end  48 - 1  of the bolt  82  faces the side panel  22  and is positioned between the arm  44  and the frame assembly  14 . In some implementations, the bolt  82  may be threadably coupled to the arm  44  or the blade  34  to allow a user to adjust the distance X 2 . 
     As shown in  FIG. 5 , the release mechanism  45  may include the first mechanism  46  on the frame assembly  14  and the second mechanism  48  on the arm  44 . In other implementations, the release mechanism  45  may include the second mechanism  48  on the frame assembly  14  and the first mechanism  46  on the arm  44 . In some examples, the mower  10  may include more than one release mechanism  45 . In particular, each of the one or more release mechanisms  45  (e.g., one release mechanism  45  on each of the side panels  22  and each of the arms  44 ). 
     By adjusting one or both of the distances X 1 , X 2  (e.g., by rotating the housing  54  and/or the bolt  82 ) the user can adjust the distance X 1 , X 2 , respectively, and therefore adjust the distance by which the first mechanism  46  (e.g., the convex end  78 ) extends into the second mechanism  48  (e.g., the concave end  48 - 1 ). For example, the user may rotate the first housing  54  on the frame assembly  14  clockwise. As the user rotates the first housing  54  in the clockwise direction, the distance by which the convex end  78  is disposed within the detent (e.g., concave end  48 - 1 ) of the second mechanism  48  changes. Conversely, as the distance X 1 , X 2  decreases, the distance by which the convex end  78  is disposed within the detent (e.g., concave end  48 - 1 ) of the second mechanism  48  decreases. 
     Similarly, a user can rotate the set screw  56  within the aperture  70  to adjust a force applied by the biasing member  58  on the protrusion  60  in a direction parallel to the axis A 2 . As the distance between the protrusion  60  and the set screw  56  decreases, the force applied by the biasing member  58  on the protrusion  60  may increase, thus increasing the frictional force imported by the bolt  82  (e.g., concave end  48 - 1 ) on the protrusion  60  (e.g., convex end  78 ) as the blade subassembly  30  rotates about the axis A 3  from the first position (e.g., engaged position) to the second position (e.g., the disengaged position). Conversely, as the distance between the protrusion  60  and the set screw  56  increases, the force applied by the biasing member  58  on the protrusion  60  may decrease, thus decreasing the frictional force imported by the bolt  82  (e.g., concave end  48 - 1 ) on the protrusion  60  (e.g., convex end  78 ) as the blade subassembly  30  rotates about the axis A 3  from the first position (e.g., engaged position) to the second position (e.g., the disengaged position). 
     While the release mechanism  45  is generally shown and described herein as including a mechanical configuration, it will be appreciated that the release mechanism can include other implementations within the scope of the present disclosure. For example, in some implementations, at least one of the first or second mechanisms  46 ,  48  includes a magnet that is operatively engaged with the other of the first or second mechanisms  46 ,  48  in the first position (e.g., the engaged position) and operatively disengaged from the other of the first or second mechanisms  46 ,  48  in the second position (e.g., the disengaged position). In particular, the housing  54  and/or the protrusion  60  may include a magnet that is selectively coupled to the bolt  82  in the first position. Similarly, the bolt  82  may include a magnet that is selectively coupled to the housing  54  and/or the protrusion  60  in the first position. By adjusting one or both of the distances X 1 , X 2  (e.g., by rotating the housing  54  and/or the bolt  82 ) the user can adjust the distance X 1 , X 2 , respectively, and therefore adjust the distance between the first mechanism  46  (e.g., the housing  54  and/or the protrusion  60 ) and the second mechanism  48  (e.g., the bolt  82 ). For example, the user may rotate the first housing  54  on the frame assembly  14  clockwise. As the user rotates the first housing  54  in the clockwise direction, the distance between the first and second mechanisms  46 ,  48 , in a direction parallel to the axis A 2 , changes, thereby changing (i) the magnetic force between the first and second mechanisms  46 ,  48  and (ii) the amount of torque required to rotate the blade subassembly  30  about the axis A 3  from the first position (e.g., engaged position) to the second position (e.g., the disengaged position). 
     Referring now to  FIGS. 7-10 , a mower  10   a  is provided and includes a frame assembly  14   a , one or more wheels  12 , and a cutter assembly  16   a . In view of the substantial similarity in structure and function of the components associated with the mower  10   a  with respect to the mower  10 , like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions (e.g., “a”) are used to identify those components that have been modified. 
     As will be described in more detail below, the mower  10   a , including the cutter assembly  16   a , may be designed to facilitate the cutting of grass, weeds, and the like during use. In this regard, while the mower  10   a  is generally shown and described herein as being a manual reel mower, it will be appreciated that the mower  10   a  may include other forms (e.g., motorized reel mower) within the scope of the present disclosure. 
     As illustrated in  FIG. 8 , the frame assembly  14   a  may include the handle  18  and a chassis  20   a  coupled to the handle  18  such that a force applied to the handle  18  by, for example, a user is transmitted to the chassis  20   a . In some implementations, the handle  18  is pivotally coupled to the chassis  20   a  such that an orientation of the handle  18  relative to the chassis  20   a  can be changed or otherwise adjusted by the user. The wheel(s)  12  may be coupled to one or both of the frame assembly  14   a  or the chassis  20   a  such that, upon application of a force on the frame assembly  14   a  (e.g., by a user, a motor, etc.), a user is able to roll and/or steer the mower  10   a  on the wheel(s)  12  along a ground surface. 
     The chassis  20   a  may include a pair of opposed side panels  22   a  and one or more support members  23  extending between the side panels  22   a . In this regard, each support member  23  may include two ends, each coupled to one or both of the chassis  20   a  (e.g., one of the side panels  22   a ). The support members  23  are configured to provide structural support and rigidity to the frame assembly  14   a  of the mower  10   a . As illustrated in  FIGS. 9A-9B , one or both of the side panels  22   a  may include the flange  25  extending inwardly toward the other of the side panels  22   a . As will be described in more detail below, during use of the mower  10   a , the flange  25  may engage a portion of the cutter assembly  16   a.    
     The cutter assembly  16   a  may include the reel  24  and a blade subassembly  30   a . As will be described in more detail below, during use of the mower  10   a , the reel  24  may engage the blade subassembly  30   a  to cut a blade of grass or other items disposed between the reel  24  and the blade subassembly  30   a.    
     The blade subassembly  30   a  may include the blade  34 , the blade bar  36 , one or more pins  44   a , and the handle  50 . As will be described in more detail below, the blade subassembly  30   a  is configured to translate relative to the frame assembly  14   a . In this regard, the blade  34  may include opposed proximal and distal ends  40 - 1   a ,  40 - 2   a  coupled to one of the pins  44   a . For example, the frame assembly  14   a  (e.g., the side panels  22   a ) may include one or more tracks  47  each extending along a third axis A 3   a . In some implementations, the track(s)  47  include, and/or otherwise define, one or more slots formed in and/or through the side panel(s)  22   a . In this regard, the track(s)  47  may be referred to herein as slots  47 . While the slots are generally illustrated as extending linearly along the third axis A 3   a , it will be appreciated that the slots  47  may extend in a arcuate manner within the scope of the present disclosure. In this regard, the axis A 3   a  may be curved such that the slots  47  may define a concave profile facing the reel  24 . 
     In the assembled configuration, a portion of the pin(s)  44   a  may be disposed within the slot(s)  47  for movement along the third axis A 3   a . For example, as will be described in more detail below, during operation of the mower  10   a , the pin(s)  44   a  may translate within the slot(s)  47  in a direction substantially parallel to the third axis A 3   a . In particular, the pins  44   a  may slide along the third axis A 3  to allow the blade  34  to move (e.g., translate) during use (e.g., during rotation of the reel  24 ) between the engaged position ( FIG. 9A ) and the disengaged position ( FIG. 9B ), as described in more detail below. In this regard, the blade  34  may translate along a linearly and/or curvilinear path in a direction transverse to the axis A 1  between the engaged position and the disengaged position. 
     In the examples described herein, the first axis A 1  of the reel  24  remains static and the second axis A 2  of the blade  34  moves (e.g., translates) relative to the first axis A 1  of the reel  24  in a second direction transverse to the first direction. In some implementations, however, the second axis A 2  of the blade  34  remains static and the first axis A 1  of the reel  24  moves (e.g., translates) relative to the second axis A 2  of the blade  34  in the second direction transverse to the first direction. Additionally, in some examples, the first axis A 1  of the reel  24  moves (e.g., translates) relative to the second axis A 2  of the blade  34  in the second direction and the second axis A 2  of the blade  34  also moves (e.g., translates) relative to the first axis A 1  of the reel  24  in the second direction. The first axis A 1  of the reel  24  may be parallel to the second axis A 2  of the blade  34  in both of the engaged position and disengaged position. 
     The first axis A 1  of the mower  10   a  may be spaced from the second axis A 2  by a first distance in a first orientation (e.g.,  FIG. 9A ). In particular, the first axis A 1  of the reel  24  may be spaced from the second axis A 2  of the blade  34  by the first distance while the blade  34  is in the first orientation (e.g., engaged position). The first axis A 1  of the mower  10   a  may be spaced from the second axis A 2  by a second distance in a second orientation (e.g.,  FIG. 9B ). That is, the first axis A 1  of the reel  24  may be spaced from the second axis A 2  of the blade  34  by the second distance while the blade  34  is in the second orientation (e.g., disengaged position). The second distance (e.g.,  FIG. 9B ) may be greater than the first distance defined by the first orientation (e.g.,  FIG. 9A ). That is, when the blade  34  moves relative to the reel  24  from the first orientation (e.g., engaged position) to the second orientation (e.g., disengaged position) the distance between the blade  34  and the reel  24  may increase from the first distance to the second distance. 
     In some implementations, the blade  34  ( i ) engages the reel  24  in the engaged position and (ii) defines a void Va ( FIG. 10 ) relative to the reel  24  in the disengaged position. In particular, in the engaged position, the blade  34  is configured to cut blades of grass or other items disposed between the reel blades  28  and the blade  34 . In the disengaged position, the void V between the reel  24  and the blade  34  is such that the blades of grass or other items disposed between the reel blades  28  and the blade  34  are not cut by the blade  34 . As illustrated in FIGS.  9 A and  9 B, in some implementations, the blade subassembly  30   a  further includes the one or more projections  51 . For example, a projection  51  may extend from one or both ends of the blade  34  toward one of the side panels  22   a  in the first orientation (e.g.,  FIG. 9A ). During use of the mower  10   a , the projection(s)  51  may engage the flange  25  to inhibit movement (e.g., translation) of the blade subassembly  30   a  along the third axis A 3  in a first direction (e.g., toward the reel), while allowing movement (e.g., translation) of the blade subassembly  30   a  along the third axis A 3  in a second direction (e.g., away from the reel) opposite the first direction. In this way, the flange  25  and the projection  51  can ensure that the blade subassembly  30   a  moves to a predetermined position upon moving from the second orientation to the first orientation. Operation of the cutter assembly  16 ,  16   a  will now be described with reference to  FIGS. 3A-4B, 6, 9A-9B, and 10 .  FIGS. 3A-3B and 9A  illustrate the blade subassembly  30 ,  30   a  in the engaged position. The user can apply a force to the handle  18  perpendicular to the first and second axes A 1 , A 2 . Upon application of force by the user on the handle  18 , the user is able to roll the mower  10 ,  10   a  on wheel(s)  12  along the ground surface. As the mower  10 ,  10   a  rolls along the ground surface, the wheels  12  and the reel  24  may rotate, and blades of grass may be positioned between the reel blades  28  and the blade  34  allowing the blade  34  to shear the blades of grass. 
     In some implementations, the biasing member  38  (e.g., torsional spring) may exert a biasing force upon the blade subassembly  30  to bias the blade subassembly  30  into the engaged position (e.g.,  FIGS. 3A and 3B ). In other implementations, gravity may cause the blade subassembly  30 ,  30   a  to rotate or translate into the engaged position from the disengaged position ( FIGS. 4A-4B and 9B ). As previously described, in some implementations, the projection(s)  51  may engage the flange  25  to inhibit movement (e.g., rotation or translation) of the blade subassembly  30 ,  30   a  about or along the third axis A 3  or A 3   a , respectively, when the blade subassembly  30 ,  30   a  is in the engaged position, maintaining the first distance between the first axis A 1  of the reel  24  and the second axis A 2  of the blade  34 . The biasing member  58  may apply a force upon the protrusion  60  to bias the protrusion  60  into engagement with the lip  76 . As previously described, the user may change the force of the biasing member  58  on the protrusion by changing the position (e.g., by threading) of the set screw  56  within the housing  54 . 
     With reference to  FIGS. 6 and 10 , the reel blades  28  may define a diameter D 1  (e.g., an outermost diameter) of the reel  24 . In the engaged position, the blade  34  may engage the reel blades  28  at a location X 1  disposed on the diameter D 1 . The diameter D 1  may define a tangent T 1  extending through the location X 1 . In a view along a direction parallel to the axis A 1 , the tangent T 1  may define a first side S 1  and a second side S 2  (e.g., relative to the views in  FIGS. 6 and 10 ). As illustrated in  FIG. 6 , the axis A 1  and the axis A 3  are disposed on the first side S 1  of the tangent T 1 . A first line L 1  may extend through the axis A 1 , the axis A 3 , and a location X 2  on the tangent T 1  when the blade  34  is in the engaged position. A second line L 2  may extend through the axis A 1  and the location X 1  when the blade  34  is in the engaged position. A third line L 3  may extend vertically through (e.g., relative to the view in  FIG. 6 ) center of gravity C when the blade  34  is in the engaged position. The outer diameter D 1  may also define a vertical tangent T 2  having a first side S 3  and a second side S 4 . In some implementations, the axis A 3  and/or the axis A 2  are disposed on the same side (e.g., S 3 ) of the vertical tangent T 2 . In some implementations, the axis A 3  is disposed above (e.g., relative to the view in  FIG. 6 ) the axis A 1  and between (e.g., relative to the view in  FIG. 6 ) the line L 2  and the line L 3 . 
     With reference to  FIG. 10 , the third axis A 3   a  may define an angle α relative to a horizontal line L 1   a  extending through the location X 1  at which the blade  34  engages the reel  24  in the engaged position. The angle α may be between zero degrees and ninety degrees. In some implementations, the angle α is equal to forty-five degrees (+/−five degrees). In some implementations, the axis A 3   a  is substantially parallel to the tangent T 1 . 
     In some examples, during use, an object (e.g., pinecone) engages the blade  34 , while the blade  34  is in the engaged position, applying a torque N 1  about the axis A 3  (e.g.,  FIG. 6 ) or a force N 1   a  along the axis A 3   a  (e.g.,  FIG. 10 ). In particular, the object may apply a force F through the location X 1  causing the torque N 1  about the axis A 3  and/or the force N 1   a  along the axis A 3   a . As the reel  24  rotates about the axis A 1 , the reel blades  28  increase the torque N 1  about the axis A 3 , or the force N 1   a  along the axis A 3   a , applied by the foreign object on the blade  34 . When the torque N 1  and/or force N 1   a  produced by the force F of the reel blades  28  on the foreign object is greater than the opposing torque N 2  and/or force W produced by gravity and/or the frictional or other force between the first and second mechanisms  46 ,  48  (e.g., the frictional force between the protrusion  60  (e.g., distal end  78 ) and the bolt  82  (e.g., concave end  48 - 1 )), the blade  34  can move (e.g., pivot about the third axis A 3  or move along the third axis A 3   a ) along a path P, P 1   a  from the engaged position to the disengaged position in real-time (e.g., during use of the mower  10 ,  10   a  to cut grass and/or without the application of a force on the blade subassembly other than the torque applied by the object, such as a pinecone, for example, engaging the blade subassembly and the reel blade), thereby increasing the distance between the second axis A 2  and the first axis A 1 . In this regard, upon application of a force on the protrusion  60  by the bolt  82  (e.g., the concave end  48 - 1 ), the bolt  82  may cause the protrusion  60  to overcome the biasing force produced by the biasing member  58 , and to move towards the set screw  56  within the housing  54 , thereby allowing the torque produced by force of the reel blades  28  on the foreign object to overcome the opposing torque produced by the frictional force between the first and second mechanisms  46 ,  48 , and thus allowing the blade  34  to pivot about the third axis A 3 , or move along the third axis A 3   a , from the engaged position to the disengaged position, where the foreign object can be removed (e.g., by the force of gravity) from engagement with blade  34  and the reel blades  28 . 
     In particular, the blade  34 , attached to the one or more arms  44  or pins  44   a , rotates about the third axis A 3 , or moves along the third axis A 3   a , to the disengaged position, such that in the disengaged position the distance between the reel  24  and the blade  34  is the second distance. The second distance between the reel  24  and the blade  34  is greater than the first distance between the reel  24  and the blade  34 . The second distance between the reel  24  and the blade  34  defines the void V, Va that allows the foreign object to expel from the void V, Va between the reel  24  and the blade  34 . After the foreign object expels from the void V, Va between the blade  34  and the reel  24 , the force perpendicular from the reel blades  28  to the second axis of the blade reduces. The weight W of the blade  34  through its center of gravity C, the biasing force from the biasing member  38 , and/or a force applied by the user (e.g., on the handle  50 ) can allow the blade  34  to pivot about the third axis A 3 , or translate along the third axis A 3   a , back to the engaged position. 
     In some implementations, where the force from the foreign object applied to the second axis A 2  of the blade  34  is low enough (e.g., when the foreign object is grass or thick weeds), the biasing force from the biasing member  38 , the weight W of the blade  34 , and/or the frictional or other force between the first and second mechanisms  46 ,  48 , keeps the blade  34  in the engaged position. 
     The adjustability of the distances X 1 , X 2 , as previously described, and the adjustability of the force produced by the biasing member  58 , as previously described, allows the release mechanism  46  to provide a consistent holding force between the blade subassembly  30  and the chassis  20  relative to rotation of the blade subassembly about the axis A 3 , and maintain the blade  34  in its proper working position (e.g.,  FIG. 3A ) until impact from a foreign object overcomes that holding force, as previously described. Similarly, in some implementations, the biasing force from the biasing member  38  may be adjusted by the user.

     The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed. 
     When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations. 
     The foregoing description has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular configuration are generally not limited to that particular configuration, but, where applicable, are interchangeable and can be used in a selected configuration, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
