In combination a mount frame adapted to be attached to a vehicle and a snowplow assembly. The mount frame comprises a pair of detachable receivers which receive a pair of horns extending rearwardly from the snowplow assembly. The snowplow assembly comprises an A-frame, a trunnion and a lift frame. A blade is attached to the front of the A-frame. A pair of spaced stand assemblies, each including a latching mechanism, support the snowplow assembly when the mount frame is separated from the snowplow assembly. The latching mechanisms secure the snowplow assembly to the mount frame.

1. A snowplow assembly comprising:a lift frame; a trunnion pivotally connected to said lift frame for pivoting movement about a transverse, horizontal axis; an A-frame having a plow blade on a forward end and being pivotally connected on a rearward end to said trunnion for pivoting movement about a
1. A snowplow assembly comprising:a lift frame; a trunnion pivotally connected to said lift frame for pivoting movement about a transverse, horizontal axis; an A-frame having a plow blade on a forward end and being pivotally connected on a rearward end to said trunnion for pivoting movement about a longitudinal, horizontal axis; and a motion generating device for effecting relative movement between said A-frame and lift frame for pivoting movement about the transverse, horizontal axis; said lift frame, trunnion, A-frame and motion generating device all being attachable to and detachable from a vehicle as one assembly. 2. The snowplow assembly of claim 1 further including a pair of transversely spaced support stands mounted to said lift frame, each support stand being height adjustable independently of the other.3. A snowplow assembly comprising:a lift frame; a plow blade; a motion generating device for effecting relative movement between said lift frame and plow blade for pivoting movement of the plow blade about a transverse, horizontal axis; and a pair of transversely spaced stand assemblies mounted to said lift frame, each said stand assembly comprising: said snowplow assembly being releasably securable to said mount frame, said snowplow assembly including a lift frame supportable by a stand, said stand being pivotal about a horizontal pivot axis between a down position in which said stand supports said snowplow assembly and an up position in which said stand does not support said snowplow assembly, said stand having a second latch element selectively engageable with said first latch element of said mount frame, wherein said first and second latch elements are engaged with one another to secure said snowplow assembly to said mount frame when said stand is in said up position, and disengaged with one another when said stand is in said down position to allow said mount frame to separate from said snowplow assembly. 4. A snowplow assembly comprising:a lift frame; a trunnion connected to said lift frame; an A-frame having a plow blade on a forward end and being connected on a rearward end to said trunnion; and a motion generating device far effecting relative movement between said A-frame and lift frame; said lift frame, trunnion, A-frame and motion generating device all being attachable to and detachable from a vehicle as one assembly; said lift frame, trunnion and A-frame being pivotally connected in such a manner that said A-frame can pivot relative to said lift frame about a transverse, horizontal axis as well as can pivot relative to said lift frame about a longitudinal, horizontal axis. 5. The snowplow assembly of claim 4 wherein said trunnion is pivotally connected to said lift frame for pivoting motion about a transverse, horizontal axis and said A-frame is pivotally connected to said trunnion for pivoting motion about a longitudinal horizontal axis.6. A snowplow assembly comprising:a lift frame; a trunnion connected to said lift frame; an A-frame having a plow blade on a forward end and being connected on a rearward end to said trunnion; and a motion generating device for effecting relative movement between said A-frame and lift frame; said lift frame, trunnion, A-frame and motion generating device all being attachable to and detachable from a vehicle as one assembly; said lift frame, trunnion, A-frame and plow blade being pivotally connected in such a manner that said plow blade can pivot relative to said lift frame about a transverse, horizontal axis as well as can pivot relative to said lift frame about a longitudinal, horizontal axis. 7. The snowplow assembly of claim 6 wherein said trunnion is pivotally connected to said lift frame for pivoting motion about a transverse, horizontal axis and said A-frame is pivotally connected to said trunnion for pivoting motion about a longitudinal, horizontal axis.8. A snowplow assembly comprising:a lift frame; a trunnion connected to said lift frame; an A-frame having a plow blade on a forward end and being connected on a rearward end to said trunnion; a motion generating device for effecting relative movement between said A-frame and lift frame; said lift frame, trunnion, A-frame and plow blade being pivotally connected in such a manner that said plow blade can pivot relative to said lift frame about a transverse, horizontal axis as well as can pivot relative to said lift frame about a longitudinal, horizontal axis; and a pair of transversely spaced support stands mounted to said lift frame for supporting said snowplow assembly above a ground surface during detachment from a vehicle, each of said support stands being height adjustable independently of the other said support stand. 9. The snowplow assembly of claim 8 wherein each of said support stands is continuously height adjustable.10. A snowplow assembly comprising:a lift frame; a plow blade; a motion generating device for effecting relative movement between said lift frame and said plow blade; and a pair of transversely spaced support stands mounted to said lift frame for supporting said lift frame above a ground surface, each of said pair of stands being height adjustable independently of the other of said stands. 11. The snowplow assembly of claim 10 wherein each of said support stands is continuously height adjustable.12. The snowplow assembly of claim 10 wherein said lift frame, plow blade and motion generating device are adapted to be attached to and detached from a vehicle as a single assembly.13. The snowplow assembly of claim 10 wherein said plow blade is operable to pivot relative to said lift frame about a longitudinal, horizontal axis.14. The snowplow assembly of claim 10 wherein said plow blade is operable to pivot relative to said lift frame about a longitudinal, horizontal axis.15. A snowplow assembly comprising;a lift frame; a plow blade; a motion generating device for effecting relative movement between said lift frame and said plow blade; and a pair of transversely spaced support stands mounted to said lift frame for supporting said lift frame above a ground surface, each of said pair of stands being height adjustable independently of the other of said stands; wherein each said support stand comprises: a bracket having opposed first and second plates and a hole in each said plate; a leg passing through said holes in said first and second plates of said bracket; a pivoting locking plate positioned intermediate said first and second plates of said bracket, said locking plate having a hole therein, said leg passing through said locking plate hole, said locking plate including a handle facilitating manual pivoting of said locking plate relative to said bracket; a first spring normally biasing an edge of said locking plate hole against said leg thereby locking said leg relative to said bracket, said handle being operable to pivot said locking plate such that said locking plate hole edge is out of engagement with said leg thereby freeing said leg for movement relative to said bracket; and a second spring normally biasing said leg relative to said bracket. 16. The snowplow assembly of claim 15 wherein said first spring is operable between one of said first and second plates of said bracket and said locking plate.17. The snowplow assembly of claim 16 wherein said second spring is operable between the other of said first and second plates of said bracket and said leg.18. A snowplow assembly comprising:a lift frame; a plow blade, said plow blade being pivotal relative to said lift frame about a longitudinal, horizontal axis; and a motion generating device for effecting relative movement between said lift frame and said plow blade; said lift frame, plow blade and motion generating device being adapted to be attached to and detached from a vehicle as a single assembly.
