ABSTRACT:
An agricultural implement, such as a hay rake, may be easily and quickly connected to or disconnected from the tow bar of a tractor. The apparatus features a large main frame assembly which extends over top of the tractor to a ground-engaging position in front of the tractor. The hay basket or other implement is connected to an end of an auxiliary lift frame which is pivotally coupled to the main frame by a hydraulic lift cylinder which permits the implement to be raised from its normal, ground-engaging position to a position far above the top of the tractor for unloading or transport. A second, lift cylinder controls the level of the implement during lifting and transport, while a third hydraulic cylinder serves to operate a push-off mechanism for unloading the hay rake. The apparatus also features a quick-connect-disconnect hitch for coupling to the draw bar of the tractor, and an integrally formed stand for supporting the main frame when uncoupled from the tractor.
