Description:
FIELD OF THE INVENTION 
     This invention relates generally to the field of mowers, and more particularly, to push reel mowers with cutting mechanisms for cutting vegetation. 
     DESCRIPTION OF THE RELATED ART 
     Push reel mowers are utilized by consumers and businesses seeking to cut vegetation (e.g., grass and weeds) in an inexpensive and environmentally friendly manner. Push reel mowers depend on a manual pushing force to trigger blades that cut vegetation. This is contrary to traditional lawn mowers that rely on gas or electric powered motors to trigger blades that cut vegetation. Thus, utilizing a push reel mower can significantly reduce the environmental impact of cutting vegetation. 
     When using a push reel mower, vegetation is cut by blades within the push reel mower. These blades are triggered by a pushing force applied by a user. Once triggered, blades begin rotating and cutting vegetation that comes into contact with such blades. In some situations, vegetation is taller than a height reachable by such blades. Attempting to cut vegetation that is taller than the height reachable by such cutting blades can be problematic and ineffective.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates a push reel mower assembly  100 . Push reel mower assembly  100  includes a cutting mechanism adaptation usable for cutting vegetation that is taller than a height reachable by traditional cutting mechanisms within a push reel mower. The cutting mechanism adaptation of  FIG. 1  serves to cut tall vegetation to a first height. Doing so allows traditional cutting mechanisms (not shown) to cut the same vegetation from the first height to a second height. Combining the two cutting mechanisms together thus allows a single push reel mower to cut vegetation that is taller than a height reachable by typical cutting mechanisms, while retaining the same environmental benefits. 
     In cases where two cutting mechanisms are not combined, tall vegetation encountered by a push reel mower can remain uncut altogether. This is because the set of cutting blades in a traditional push reel mower can be prevented from reaching the tall vegetation whenever the push reel mower is operated. As a push reel mower approaches tall vegetation, the mechanics of the cutting mechanism assembly prevents the set of cutting blades from trapping and cutting the tall vegetation. In these cases, a gas or electric powered lawn mower may be needed to cut tall vegetation to a height reachable by the set of cutting blades in a traditional push reel mower. Relying on a gas or electric powered lawn mower before being able to use a push reel mower significantly reduces the practicality and environmental attractiveness of using a push reel mower in the first place. 
     The cutting mechanism of  FIG. 1  allows a user of a push reel mower to cut vegetation to a first height (e.g., via a cutting mechanism adaptation) that is then reachable by a set of cutting blades within a push reel mower. Push reel mower assembly  100  includes wheels  110 . Push reel mower assembly  100  also includes a cutting mechanism adaptation, which further includes rod  120 , bottom beveled gears  130 , bracket  140 , blades  150 , pins  160 , ball bearings  170 , top beveled gears  180 , and springs  190 . Although not shown, push reel mower assembly  100  can also include more or less components than those illustrated in  FIG. 1 . 
     Rod  120  is a shaft and can be made of materials (e.g., metal or non-metal) that allow for the transfer of motion. Rod  120  can also be hollow or solid. In addition, rod  120  can be shaped in one of many forms, so long as rod  120  allows for bottom beveled gears  130  to fit onto rod  120 . As an example, rod  120  can be a solid, cylindrical shape made of stainless steel material. Rod  120  is also connected perpendicular to each wheel  110 . Rod  120  can be securely held in place relative to the inner portion of wheels  110  via a holding plate and ball bearing within wheels  110 . By connecting rod  120  to wheels  110  via gears, rod  120  is automatically triggered to begin rotating as wheels  110  are spun by a user of a push reel mower. 
     The location in which rod  120  is connected to each wheel  110  defines the height at which blades  150  are located. Specifically, rod  120  can be connected to each wheel  110  at any location along a predetermined perimeter of each wheel  110 . The location in which rod  120  is connected to each wheel  110  defines the resulting location of blades  150 , given the manner in which the components of the cutting mechanism adaptation fit and operate together. 
     The rotation of rod  120  triggers the rotation of bottom beveled gears  130 , top beveled gears  180 , and blades  150 . Thus, if a different height for blades  150  is desired, the location in which rod  120  is connected to each wheel  110  should be varied accordingly. For example, if blades  150  are to be located lower to the ground, rod  120  can be connected to each wheel  110  at a location along the outer perimeter that is closer to the bottom of each wheel  110 . Alternatively, if a taller height is desirable for blades  150 , rod  120  can be connected to each wheel  110  at a location along the outer perimeter that is closer to the top of each wheel  110 . 
     Rod  120  begins rotating when push reel mower assembly  100  is operated by a user. A user can operate the push reel mower, for example, by applying a pushing force to a handle that is connected to push reel mower assembly  100 . For example, if push reel mower assembly  100  is pushed by a user via a handle, the pushing motion causes wheels  110  to move forward and rod  120  to begin rotating, thereby triggering the operation of blades  150  to begin cutting vegetation. 
     A push reel mower assembly  100  can also be configured to provide optional functionality of the cutting mechanism adaptation. This can be achieved, for example, by adding a cable to push reel mower assembly  100  that is controlled by a lever for engaging or disengaging rod  120 . Such a cable can be attached to the handle of a push reel mower assembly  100 , from which a user can operate the cable to engage or disengage rod  120 . Providing a user with an option of engaging or disengaging rod  120  can be desirable in cases where the functionality provided by the cutting mechanism adaptation is not always needed. As an example, a cutting mechanism adaptation may be needed whenever vegetation is taller than a height reachable by a set of cutting blades typically included in a push reel mower. However, the cutting mechanism adaptation may not be needed whenever the height of vegetation is within a height reachable by the set of cutting blades typically included in a push reel mower. Making use of the cutting mechanism adaptation requires extra pushing force on behalf of a user. Thus, disengaging rod  120  whenever possible can significantly reduce the amount of force needed to operate a push reel mower. 
     Rod  120  also includes a set of bottom beveled gears  130 . As shown, rod  120  includes a set of five bottom beveled gears  130 . In other embodiments, however, rod  120  can include more or less bottom beveled gears  130  than those illustrated in  FIG. 1 . Bottom beveled gears  130  can be connected to rod  120 , in one of several ways, to ensure that each bottom beveled gear  130  is secured to rod  120  and does not move during operation. For example, bottom beveled gears  130  can be connected to rod  120  via set screws made of hardened steel. Alternatively, bottom beveled gears  130  can be connected to rod  120  by welding each bottom beveled gear  130  to rod  120 . 
     The spacing between the bottom beveled gears  130  can be varied. Each bottom beveled gear  130  is coupled to a corresponding set of blades  150  (e.g., via bracket  140 , pins  160 , top beveled gears  180 , and springs  190 ). Thus, the spacing between bottom beveled gears  130  should be enough to allow each set of blades  150  to rotate completely without interfering with neighboring set of blades. 
     Each bottom beveled gear  130  is a circular rotating machine part with teeth along the outer edges. The teeth along the outer edges of bottom beveled gears  130  are in direct contact with interlocking teeth located along the outer edges of corresponding top beveled gears  180 . By using interlocking teeth at bottom beveled gears  130  and top beveled gears  180 , torque motion can be transferred from bottom beveled gears  130  to top beveled gears  180  without slipping. As shown, bottom beveled gears  130  are larger in size than top beveled gears  180 , thereby creating different rotational speeds and torque for bottom beveled gears  130  and top beveled gears  180 . 
     Once rotational speed and torque is transferred from bottom beveled gears  130  to top beveled gears  180 , pins  160  are triggered to being rotating, which in turns triggers the rotation of blades  150  to begin cutting vegetation. In other embodiments, rotational speed and torque can be transferred by other means. For example, rotational speed and torque can also be transferred by use of axles, sprockets and chains or bands and pulleys between rod  120  and blades  150 . 
     The cutting mechanism of  FIG. 1  also includes bracket  140 . Bracket  140  is likewise attached to each wheel  110 . One way to attach bracket  140  to the inner portion of each wheel  110  is to weld or glue bracket  140  to each wheel  110 . Bracket  140  is made of a hardened steel material, such as stainless steel, to ensure bracket  140  withstands the weight of blades  150 . As shown, bracket  140  includes five sets of blades  150  for cutting vegetation. Such vegetation is cut to a height that is equivalent to the height of blades  150 . In some embodiments, a push reel mower assembly  100  can also include an adjustable height bracket that varies the height of blades  150  and therefore the height at which vegetation is cut by blades  150 . Such an adjustable height bracket can be connected to wheels  110  and/or blades  150 . 
     Each set of blades  150  is made up of two or more blades for cutting vegetation. Each set of blades  150  includes at least one fixed blade and at least one rotating blade. As the one or more rotating blades come in contact with the fixed blades, vegetation caught between the blades is cut. Spring  190  is used to maintain compression between blades  150 . A blade protection guard can also be added to push reel mower assembly  100  to help protect the user from coming in contact with blades  150 . 
     Each set of blades  150  is connected to and held against bracket  140  via pins  160 , ball bearings  170 , and springs  190 . Example materials for pin  160  and ball bearings  170  can include galvanized coated steel, stainless steel, iron, and brass. Example materials for springs  190  can include stainless steel or other types of materials that possess corrosion-free characteristics. 
     The head of each pin  160  is wider than the body of pin  160  and configured to fit tightly against one side of bracket  140  via a ball bearing  170 . The head of each pin  160  is therefore located on the opposite side of bracket  140 , as compared to blades  150 . Ball bearing  170 , which is used to connect the head of pin  160  to bracket  140 , mechanically attaches the pin to the bracket, keeping the pin in place, while minimizing friction experienced throughout the operation of a push reel mower assembly  100 . The body of each pin  160  passes through ball bearing  170 , through bracket  140 , through blades  150 , and top beveled gear  180 . Pin  160  is connected to top beveled gear  180  via a set screw. Alternatively, pin  160  can be glued or welded to top beveled gear  180 . 
     Springs  190  are used to maintain clearances between blades  150 . Maintaining clearances between blades  150  allows blades  150  to remain in place throughout the operation of push reel mower assembly  100  and allows blades  150  to cut vegetation encountered by blades  150 . Spring  190  is formed like a coil and wraps around the body of pin  160  between top beveled gears  180  and blades  150 . 
     As assembled, the rotation of wheels  110  causes rod  120  to begin rotating, which in turn causes bottom beveled gears  130  and top beveled gears  180  to begin rotating in opposite directions. Whenever top beveled gear  180  begins rotating, pin  160  begins rotating as a result. The rotation of pin  160  causes the one or more rotating blades  150  to begin rotating as well. Whenever the one or more rotating blades approach the fixed blade, any vegetation coming in contact with the sharpened edges of blades  150  will be cut. Vegetation is cut to a height that is equivalent to the height of blades  150 . Doing so then allows such vegetation to be cut a second time by a set of cutting blades typically found within push reel mowers. 
       FIG. 2  illustrates a bracket  200  (e.g., such as bracket  140  of  FIG. 1 ). Bracket  200  is a support bar used to hold the blade assembly for a cutting mechanism adaptation. Bracket  200  is typically made of a rigid material, which is able to support the combined weight of all blade assemblies. For example, bracket  200  can be made of steel, aluminum, or plastic. 
     As shown, bracket  200  is a rectangular support bar with five sets of holes  210 . Bracket  200  is typically long and slender. An example dimension for the width of bracket  200  is around 1-2 inches. The length of bracket  200  is equivalent to the space that exists between wheels in a push reel mower (e.g., the spacing between wheels  110  in  FIG. 1 ). 
     The number of holes  210  on bracket  200  can vary. Holes  210  are holes drilled into bracket  200  for the purpose of passing a pin assembly from one side of bracket  200  to the other. A pin assembly passed through bracket  200  is used to hold a set of blades against bracket  200  throughout the operation of a push reel mower. Thus, the number of holes  210  drilled onto bracket  200  is typically equivalent to the number of blade assemblies used by a cutting mechanism. Although not shown, bracket  200  can include more or less holes  210  to correspond with the number of desirable blade assemblies in a cutting mechanism adaptation. 
     Holes  210  may be spaced at even distances from each other and from the ends of bracket  200 . As shown, holes  210  are spaced equally from one another. As an example, holes  210  may be spaced around 3.5-4.5 inches apart, whenever five holes are used. It is possible, however, to have holes  210  be spaced unevenly from each other, so long as the spacing between two adjacent holes  210  allows for the operation of neighboring blade assemblies without interference. 
       FIG. 3  illustrates a bracket and blade assembly configuration  300 . As shown, bracket and blade assembly configuration  300  includes a bracket  310  with a set of holes  315 . Through each hole  315  is a set of blades consisting of a fixed blade  320  and a rotating blade  330 . Although not shown, bracket  310  can include more or less holes  315 , more or less blades  320 , and more or less blades  330  than those shown in  FIG. 3 . 
     Fixed blades  320  and rotating blades  330  are typically made of the same material, although the material used for fixed blades  320  and rotating blades  330  may differ. The material selected for fixed blades  320  and rotating blades  330  should be one that has enough rigidity to withstand frequent and extensive use of a blade assembly. In addition, the material selected for fixed blades  320  and rotating blades  330  should also be able to withstand moisture and remain corrosion-free. Fixed blades  320  and rotating blades  330  may come into contact with water whenever such blades are pushed along wet or damp vegetation. As such, the material of such blades should be one that helps prevents corrosion due to moisture. An example material that can be used for fixed blades  320  and rotating blades  330  is stainless steel. 
     Each set of fixed blades  320  and rotating blades  330  are held together by a pin assembly that runs through each hole  315 . This pin assembly aligns and compresses fixed blades  320  and rotating blades  330 , which ensures that fixed blades  320  and rotating blades  330  are pressed together throughout the operation of a push reel mower to create a scissor-like cutting motion. In order to create a scissor-like cutting motion, fixed blades  320  and rotating blades  330  are maintained in direct contact with each other via curved leading edges to ensure thorough cutting of vegetation. In some embodiments, a pressure adjustment component can also be added to a push reel mower to apply varying levels of pressure between fixed blades  320  and rotating blades  330 . 
     One edge of each fixed blade  320  and each rotating blade  330  is sharpened. These sharpened edges are illustrated as sharpened edges  340  and  350 . Each sharpened edge  340  corresponds to a sharpened edge of a fixed blade  320 , and each sharpened edge  350  corresponds to a sharpened edge of a rotating blade  330 . Vegetation is cut as sharpened edge  350  of a rotating blade  330  comes in contact with sharpened edge  340  of a fixed blade  320  and continues rotating past fixed blade  320 . The rotation of rotating blade  330  creates a scissor-like motion that traps vegetation between sharpened edges  340  and  350 , thereby cutting vegetation to a height that is equal to the height of fixed blades  320  and rotating blades  330 , as measured from the base of a push reel mower. 
     Rotating blade  330 , as shown, is the bottom blade and sits directly against bracket  310 . Fixed blade  320 , as shown, is the top blade and sits directly on top of rotating blade  330 . Alternatively, fixed blade  320  and rotating blade  330  can be swapped to have fixed blade  320  become the bottom blade and rotating blade  320  become the top blade. 
     Fixed blade  320  remains fixed throughout the operation of a push reel mower. The position of fixed blade  320 , relative to bracket  310 , can determine the reach of vegetation that can be trapped between fixed blades  320  and rotating blades  330 . This is because fixed blade  320  guides vegetation encountered by fixed blade  320  towards the edge of rotating blade  330  to result in the cutting of such vegetation. As an example, fixed blade  320  can be positioned to provide a forty-five degree angle relative to bracket  310 . Other positions for fixed blade  320  can also be utilized. 
     The size and shape of fixed blades  320  and rotating blades  330  can be varied according to the number of blade assemblies used along bracket  310  and the height clearances offered by a push reel mower assembly. For example, fixed blade  320  may be the same size and shape as rotating blade  330 . Alternatively, fixed blade  320  and rotating blade  330  may be of different sizes and shapes. Any combination of sizes and shapes that allows the two blades to trap and cut vegetation without interfering with neighboring blades can also be employed. 
       FIG. 4  illustrates a top blade  410  (e.g., such as fixed blade  320  of  FIG. 3 ) and bottom blade  420  (e.g., such as rotating blade  330  of  FIG. 3 ). As shown, top blade  410  and bottom blade  420  are of different sizes and of different shapes. Alternatively, top blade  410  and bottom blade  420  can also be of the same size and shape. 
     As shown, top blade  410  has a cone-like shape with two edges of equal length and a third rounded edge. Top blade  410  can also have other shapes that include pointy edges, rounded edges, semi-rounded edges, square edges, and so on. In addition, the edges of top blade  410  can also have equal or unequal lengths. As shown, one edge of top blade  410  is sharpened. This edge is illustrated as sharpened edge  430  and is used to cut vegetation. 
     Top blade  410  also includes a hole  450  near the rounded edge. Hole  450  is hollow and allows a pin assembly to pass through from one side of top blade  410  to the other. By passing a pin assembly through hole  450 , top blade  410  is aligned and secured in place during operation. The sides of top blade  410  can be flattened or rounded. As shown, top blade  410  includes a slightly rounded top side and a flat bottom side. Alternatively, the top and bottom sides of top blade  410  can both be flattened and of equal lengths. Additionally, the bottom side of top blade  410  includes curvature to allow top blade  410  to come in contact with bottom blade  420  at a single point during operation, to produce a scissor-like motion. 
     The size of top blade  410  can depend on various factors, including the desired reach of such a blade and the number of blade assemblies to be used within a bracket. An example set of dimensions for top blade  410  can be approximately 3-4 inches in length, as measured from the center of hole  450  to the opposite edge of top blade  410 , and approximately 0-0.25 inches in thickness. 
     Bottom blade  420 , as shown, has a different shape than that of top blade  410 . As shown, bottom blade  420  has a more rectangular-like shape with three flat edges of unequal lengths and one rounded edge. Bottom blade  420  can also have other shapes that include pointy edges, rounded edges, semi-rounded edges, square edges, and so on. The edges of bottom blade  420  can also have equal or unequal lengths. One edge of bottom blade  420  is sharpened, as illustrated by sharpened edge  440 , and is used to cut vegetation. 
     Bottom blade  420  also includes a hole  460  near the rounded edge to allow a pin assembly to pass through from one side of bottom blade  420  to the other. Doing so allows bottom blade  420  to be aligned and secured during operation of a push reel mower. The sides of bottom blade  420  can be flattened or rounded. As shown, bottom blade  420  includes a flattened top side and a rounded bottom side. Alternatively, the top and bottom sides of bottom blade  420  can be flattened and of equal lengths. The top side of bottom blade  420  includes curvature to allow bottom blade  420  to come in contact with top blade  410  at a single point during operation. Doing so produces a scissor-like motion. 
     The size of bottom blade  420  can also vary according to a desired reach of bottom blade  420  and the number of blade assemblies to be used within a bracket. An example set of dimensions for top blade  420  can be approximately 2-3 inches in length, as measured from the center of hole  460  to the opposite edge of bottom blade  420 , and approximately 0-0.25 inches in thickness. 
       FIG. 5  illustrates a pin assembly  500 . Pin assembly  500  includes a pin  510 , a ball bearing  520 , a top blade  530 , a bottom blade  540 , a blade spring  550 , a top beveled gear  560 , and a bottom beveled gear  570 . Pin  510  is a device used to fasten and align inner bushings of ball bearing  520 , top blade  530 , bottom blade  540 , blade spring  550 , top beveled gear  560 , and bottom beveled gear  570  together. 
     Pin  510  can be made of a variety of structurally rigid and corrosion-free materials. Some example materials for pin  510  include steel, galvanized coated steel, brass, or copper. Pin  510  includes a head and a slender body. One example of pin  510  can be a 0.25 inch grooved pin. The head of pin  510  sits on top of ball bearing  520 . The slender body of pin  510  runs through a bracket (not shown), top blade  530 , bottom blade  540 , blade spring  550 , top beveled gear  560 , and bottom beveled gear  570 . The use of pin  510  prevents the components of pin assembly  500  from disengaging and/or misaligning during operation of a push reel mower. 
     Applying a pushing force to a push reel mower causes pin  510  to rotate, which subsequently causes bottom blade  540  to rotate correspondingly. This is because of the way that pin  510  and bottom blade  540  are interconnected. Pin  510  is attached to bottom blade  540  by matching a groove on pin  510  with a hole on bottom blade  540 . The hole on bottom blade  540  is shaped to match the groove on pin  510  in order to have the rotation of pin  510  trigger the rotation of bottom blade  540 . By contrast, the hole on top blade  530  is not matched to the groove on pin  510 . Instead, the hole on top blade  530  is completely round and allows pin  510  to rotate through such a hole without triggering the rotation of top blade  530 . For example, pin  510  and the hole on bottom blade  540  can be shaped as a semi-circle while the hole on top blade  530  can be shaped as a circle that allows for the rotation of pin  510 . 
     In operation, the rotation of pin  510  causes the rotation of bottom blade  540 . As bottom blade  540  rotates, bottom blade  540  comes in contact with top blade  550  to cut vegetation. This happens as a sharpened edge of bottom blade  540  approaches a sharpened edge of top blade  530 . Any vegetation caught between the two sharpened edges is cut along the way. 
     Ball bearing  520  is a ring-shaped device used to transmit motion between moving parts while minimizing friction. As shown, ball bearing  520  sits between the head of pin  510  and top blade  530 . The body of pin  510  is passed through the inside hollow portion of ball bearing  520  to reduce rotational friction caused by the rotation of pin  510 . Ball bearing  520  can be made of several structurally rigid materials, such as galvanized coated steel, stainless steel, chrome steel, and ceramic. 
     Top blade  530  and bottom blade  540  are cutting devices used within a cutting mechanism adaptation. As shown, top blade  530  and bottom blade  540  are located between ball bearing  520  and blade spring  550 . Top blade  530  and bottom blade  540  can be made of several different corrosion-free and structurally rigid materials. One example material is stainless steel. In addition, top blade  530  remains in contact with bottom blade  540  at all times. By doing so, top blade  530  and bottom blade  540  can create a scissor-like cutting motion during the operation of a push reel mower. Vegetation caught between the sharpened edges of top blade  530  and bottom blade  540  is cut. 
     Blade spring  550  is an elastic device used to store mechanical energy. As shown, blade spring  550  is located between bottom blade  540  and top beveled gear  560 . Blade spring  550  can be made of stainless steel, other hardened steel materials, bronze, titanium, and so on. Ideally, the material selected for blade spring  550  is one that is structurally rigid, elastic, and corrosion-free. 
     Blade spring  550  keeps compression between top blade  530  and bottom blade  540  throughout the operation of a push reel mower. Keeping compression between top blade  530  and bottom blade  540  at all times serves to keep top blade  530  and bottom blade  540  in position and in direct contact with each other during the operation of a push reel mower. Failure to keep a proper amount of compression between the blades can prevent the scissor-like motion needed to cut vegetation. In addition, maintaining compression between top blade  530  and bottom blade  540  also serves to keep tight clearances between blades, particularly as the blades wear out. 
     Top beveled gear  560  is a rounded gear device that includes teeth along the outer edges. Similarly, bottom beveled gear  570  is a cylindrical gear that also includes teeth along the outer edges. Top beveled gear  560  and bottom beveled gear  570  should be made of structurally rigid and corrosion-free material. Examples of such materials include stainless steel, plastic, aluminum, and brass. 
     Top beveled gear  560  and bottom beveled gear  570  are joined together with teeth to prevent slipping and to transmit torque and rotational energy from one component to the other. During operation of a push reel mower, the rotation of bottom beveled gear  570  transmits torque and rotation to top beveled gear  560 . The transferred torque and rotation of top beveled gear  560  causes the rotation of pin  510 , which causes the rotation of bottom blade  540  and ultimately the cutting of vegetation by top blade  530  and bottom blade  540 . 
     In other embodiments, top beveled gear  560  and bottom beveled gear  570  can be replaced with wheels to form a pulley system that can also transmit torque and rotational speed from one set of components to another. In addition, a belt and pulley or a chain and sprocket combination can also be employed instead of top beveled gear  560  and bottom beveled gear  570 . 
       FIG. 6  illustrates a front view of a push reel mower assembly  600  with a total of two cutting mechanisms. Push reel mower implementation  600  includes a set of wheels  610 . Located between wheels  610  are two cutting mechanisms (e.g., a traditional cutting mechanism and a second cutting mechanism, such as the cutting mechanism adaptation shown in  FIG. 1 ). The cutting mechanism adaptation is located in front of and above traditional cutting mechanism to allow the cutting mechanism adaptation to reach vegetation first and cut such vegetation to a height that is then reachable by traditional cutting mechanisms. 
     When push reel mower assembly  600  is in operation (e.g., wheels  610  are being pushed), the rotation of wheels  610  triggers the rotation of both cutting mechanisms. As vegetation is encountered, the cutting mechanism adaptation reaches the vegetation first and cuts the vegetation to a first height (e.g., a height reachable by traditional cutting mechanisms). Thereafter, the same vegetation is encountered by traditional cutting mechanisms, which then cut the vegetation to a second height. 
     In cases where vegetation is not taller than a height reachable by the cutting mechanism adaptation, the cutting mechanism adaptation can be disengaged. When the cutting mechanism adaptation is disengaged, vegetation is cut only once by traditional cutting mechanisms. Disengaging a cutting mechanism adaptation in this scenario translates into less force needed to operate push reel mower assembly  600 . 
       FIG. 7  illustrates a side view of a push reel mower assembly with two cutting mechanisms (e.g., such as push reel mower assembly  600  of  FIG. 6 ). Push reel mower assembly  700  includes wheel  710 , a first cutting mechanism  720  (e.g., such as the cutting mechanism adaptation of  FIG. 1 ), and a second cutting mechanism  730  (e.g., a traditional cutting mechanism). As shown, the first cutting mechanism  720  is located in front of and above the second cutting mechanism  720 . This allows the first cutting mechanism  720  to cut vegetation to a first height and second cutting mechanism  730  to cut vegetation to a second height thereafter. 
     Push reel mower assembly  700  also includes a back wheel  740  connected to wheel  710 . Together wheels  710  and  740  can provide a flat base for push reel mower assembly  700 . Alternatively, push reel mower assembly can be assembled without back wheel  740 . A handle can also be attached to push reel mower assembly  700  to help operate push reel mower assembly  700 .
