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. The latch lever operably frees the jack stand for movement into the extended position when the latch pins are in the unlatched position and operably prevents jack stand movement maintaining the jack stand in the retracted position when the latch pins are in the latched position.
