       FIELD OF THE INVENTION 
       [0005]    This invention relates to devices which can move heavy industrial equipment, in particular motor grader blades. 
       BACKGROUND OF THE INVENTION 
       [0006]    Prior to the present invention, the primary way of moving a motor grader blade was to have two strong people lift it. This creates issues with training and handling situations where an individual is injured. As a result, McDermott (U.S. Pat. No. 5,071,183) invented a lift which can be attached to a crane to lift a motor grader blade. This invention succeeded in work places that had access to a crane and a licensed crane operator. More frequently, these additional facilities are not available or effective in smaller workplaces leading to the need for the present invention. Similarly, conventional hand trucks such as Williamson (U.S. Pat. No. 5,993,134) fail to provide the balance needed to move a motor grader blade which is taught in the present invention. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    The present invention includes methods, systems, and other means for a blade lift tool.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    Embodiments of the present invention overcome many of the obstacles associated with moving a motor grader blade, and now will be described more fully hereinafter with reference to the accompanying drawings that show some, but not all embodiments of the claimed inventions. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. 
         [0015]      FIG. 1  shows the invention in use. User  48  desires to move a motor grinder blade with blade lift tool  10 . Blade lift tool  10  comprises handle bar  12  (which is shown in more detail in  FIG. 2-FIG .  4 ), which is mechanically coupled to center riser  16 . Center riser  16  is mechanically coupled to bottom round tubing  20  (not shown) which is further mechanically coupled to first tire  42  and second tire  42  (which is shown in more detail in  FIG. 4 ). Bottom round tubing  20  (not shown) is additionally mechanically coupled bottom bar square tubing  18 . Bottom bar square tubing  18  is further mechanically coupled to first pin  28  and second pin  28  as shown in  FIG. 5 . 
         [0016]      FIG. 2  shows a perspective view of blade lift tool  10  in more detail. As noted above, handle  12  is mechanically coupled to center riser  16  which is further mechanically coupled to bottom round tubing  20 . Bottom round tubing  20  is mechanically coupled to bottom bar square tubing  18 , Here, handle  12  further comprises safety grips  14 . First tire  42  is mechanically coupled to first wheel  40  which is further mechanically coupled to axel  38 . First wheel hub  22  can be mechanically coupled to axel  38  as shown in  FIG. 4 . Axel  38  is further mechanically coupled to second wheel hub  22  as shown in  FIG. 4 . Second wheel hub  22  is mechanically coupled to second tire  42  which is further mechanical coupled to second wheel  40  in a well-known manner. 
         [0017]      FIG. 3  shows another perspective view of blade lift tool  10 . As noted above, bottom round tubing  20  is mechanically coupled to bottom bar square tubing  18 . Bottom bar square tubing  18  is mechanically coupled to first blade stop  24  which is mechanically coupled to first pin  28  with first nut  36  as shown in  FIG. 5 . Similarly, Bottom bar square tubing  18  is mechanically coupled to second blade stop  24  which is mechanically coupled to second pin  28  with second nut  36  as shown in  FIG. 5 . One novel feature of the device is first notch  30 . First notch  30  is an anti-slip notch that will prevent a motor grinder blade from falling off blade lift tool  10  by giving a place for a portion of the blade to sit. 
         [0018]      FIG. 4  provides an exploded view of blade lift tool  10 . As shown here, first wheel hub  22  and second wheel hub  22  are both mechanically coupled to bottom round tubing  20 . Axel  38  slides through first wheel hub  22  where it is mechanically coupled to first tire  42  by first wheel retainer  44  and first wheel retainer set screw  46 . Similarly, axel  38  slides through second wheel hub  22  where it is mechanically coupled to second tire  42  by second wheel retainer  44  (not shown) and second wheel retainer set screw  46  (not shown). 
         [0019]      FIG. 5  shows first pin  28  in more detail. As noted above bottom bar square tubing  18  is mechanically coupled to first blade stop  24 . First blade stop  24  comprises first hole  26 . First pin  28  comprises first notch  30  and first threaded portion  32 . A user mechanically couples first pin  28  to first blade stop  24  by inserting first threaded portion  32  into first hole  26  and completing the mechanical couple by using first w  34  and first nut  36  in a well-known manner. Similarly, bottom bar square tubing  18  is mechanically coupled to second blade stop  24 . Second blade stop  24  comprises second hole  26 . Second pin  28  comprises second notch  30  and second threaded portion  32 . A user mechanically couples second pin  28  to second blade stop  24  by inserting second threaded portion  32  into second hole  26  and completing the mechanical couple by using second washer  34  and second nut  36  in a well-known manner. 
         [0020]    To use blade lift tool  10 , user  48  maneuvers blade lift tool  10  to a new motor grader blade. User  48  then tilts blade lift tool  10  to partially raise the motor grader blade. Once raised, user  48  installs first pin  28  and second pin  28  as explained in  FIG. 5  which allow for easy centering and handling of the motor grader blade. To do this user  48  aligns first notch  30  against the back side of the motor grader blade and pulls back on handle  12  rotating which moves blade lift tool  10  about axel  38  until the motor grader blade is safely aligned against first notch  30  and second notch  30 . User  48  can maneuver the motor grader blade to the desired location. Once at the desired location, a user can align the motor grader blade in a predetermined position and then remove first pin  28  and second pin  28  allowing the motor grader blade to fall into place. The user can then install the new motor grader blade in a manner well known in the art.
