description A pick-up type drawbar assembly includes a frame which is fixed to the transmission casing of a tractor. The frame includes a fore-and-aft extending link slot and a curved bellcrank slot. A drawbar link has a rear end which includes an implement engaging hook and a forward end which is pivoted about a pin which slides in the link slot. A bellcrank has one corner pivotally coupled to the drawbar link and another corner pivotally coupled to the frame. A curved slot is located near a third corner of the bellcrank. A pivot pin extends through and is slidable with the curved slots in the frame and the bellcrank. A hydraulic cylinder has a housing pivotally supported in the frame. The rod of the cylinder is coupled to the pivot pin so that extension of the cylinder pivots the bellcrank and lowers the drawbar link. As the link lowers, its forward end and its hook end move rearwardly.
