Abstract: A snowplow and mount assembly comprising a mount frame adapted to be secured to a vehicle, and a snowplow frame. One of the mount frame and the snowplow frame has first and second arms and the other of the mount frame and snowplow frame has first and second receivers, the first and second receivers receiving the first and second arms, respectively. Respective ones of first and second latch pins removably secure the first and second arms in the first and second receivers. A latch lever is operably associated with the first and second latch pins and simultaneously actuates the latch pins to latched and unlatched positions. The snowplow frame includes a jack stand movable to and between an extended ground contacting and snowplow frame supporting position and a retracted ground noncontacting and snowplow frame nonsupporting position.

Abstract: 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.
