Abstract

A fluid cylinder mechanism couplable to a vehicle and having a piston slidable within the cylinder, a rod couplable to an implement and shiftable within an opening in the piston, the rod being adapted to shift vertically within the piston as an implement rides over ground undulations, and an abutment mechanism coupled to the rod for abutment with the piston when the piston shifts upwardly due to selective forcing of fluid into the rod end of the cylinder by the operator to transfer the weight of the implement to the vehicle or to lift the implement for transport.
