ABSTRACT:
A snowplow (20) adapted for being attached to or detached from a vehicle (22) having a frame (24). The snowplow includes a mount frame (26) for connection to the vehicle frame, a support frame (32), a lift assembly (38) and a blade assembly. The blade assembly of the invention includes a blade (30), a blade cutting edge (31) and a wheel support assembly (56). The support frame includes a forward end (33) for supporting the blade and a rearward end (36) for connection to the vehicle. When detached from the vehicle as a single unit, the resultant weight on the rearward end of the support frame may be supported on a ground surface (46) by a jack stand (48). The wheel support assembly includes a yoke assembly (60) having a pair of sides (62) for supporting a wheel (57), a biased spring 80 mounted onto a stud (76) for allowing the yoke assembly to rotate from an upward inoperative position to a downward load support position, a handle (64), a support plate (65) and a bracket assembly (90) for mounting the wheel assembly to the snowplow. The wheel assembly is rotatable between the inoperative position and the load supporting position and is in the load supporting position when the snowplow is detached from the vehicle. An advantage of this invention is that nearly all of the weight of the snowplow is supported by the wheel support assembly when the snowplow is detached from the vehicle.
