Abstract
The assembly (10) is for use with a mecnanical leverage system (24) mounted on a frame (14), for instance the frame of a vehicle (12), to move an implement (16) between a lowered position and a lifted position. The assembly (10) comprises an elongated first lever arm (30) and a second lever arm (40) that is in motion-transmitting engagement with a lower end (32) of the first lever arm (30). A detent member (50) is provided to lock the second lever arm (40) in an intermediary position located between a first and a second limit position thereof. The intermediary position corresponds to the lifted position of the implement (16). The detent member (50) is released by further pivoting the first lever arm (30) so as to move the second lever arm (40) from its intermediary position to its second limit position. The detent member (50) is then released without having to independently operate a locking mechanism or to move the first lever arm (30) sidewards.
