A remotely actuatable coupling device having a ball hitch mounted on an agricultural tractor is adapted to accommodate different type hitch-engaging means carried by the tongue of the towed implement. Raising and lowering of the implement tongue is accomplished by the movement of a pick-up bale suspended from the pivotal draft links of the tractor. A keeper, mounted on the tractor and which can be controlled from the operator's station, releasably locks the engaging means to the ball hitch.
