ABSTRACT:
A hitch device for connecting an implement to a tractor is provided. A male plug is operatively connected to the three point hitch, power take-off and hydraulic system of the tractor. A female shell is operatively connected to the tongue, drive train and hydraulic system of the implement. The male plug and female shell can be connected and disconnected while the operator remains seated on the tractor. The mating engagement of the male plug within the female shell automatically connects the drive train of the implement to the power take-off of the tractor and automatically connects the hydraulic system of the implement to the hydraulic system of the tractor. Releasable locking clips are provided to lock the male plug within the female shell.
