Abstract
The mechanism comprises in combination an upstanding frame mounted to the front of the chassis of a land vehicle and adapted to mount a front plow assembly, and a side frame mounted to the side chassis of the land vehicle for mounting a side wing plow. Both the front and side frames include a sub-frame pivotally mounted to the lower portion of the upstanding frame, hydraulic means for moving the sub-frame in an arc between a retracted and an extended position. The sub-frame has a free end mounting an engagement member remote from the pivot axis and adapted to engage a sub-frame on a plow assembly frame. The sub-frame on the plow assembly includes a hook member open downwardly and adapted to receive the engagement member of the free end of the first sub-frame and locking means associated with the first and second sub-frames for locking the first and second sub-frames together when the engagement member is engaged within the hook member and the pivoted sub-frame is in a retracted position.
