ABSTRACT:
A device for attaching a working implement to the front of a running vehicle for performing work while following the ground comprises a pair of opposite inflexible links pivoted at their rear ends to the front of the vehicle. These inflexible links are movable upwardly or downwardly and each link has a front end for movably supporting the front portion of the implement about a lateral pivot. A pair of opposite suspenders are each mounted on a longitudinally intermediate portion of each link for suspending the rear portion of the implement, each of the suspenders including a rod assembly pivotally connectable to the implement's rear portion and a resilient member. The rod assembly is inserted in an upstanding state through the link and is movable axially thereof to thereby permit upward or downward movement of the implement's rear portion due to the movement of the implement about the pivot. The resilient member is provided around an upper portion of the rod assembly above the link and elastically bears against the link. A lift unit is provided between the vehicle and the links for raising or lowering the implement through the links and the suspenders. The lift unit permits upward or downward movement and sidewise tilting of the entire implement due to the pivotal movement of each of the links independent of the other link.
