    Abstract: A mounting frame 10 is intended to be used with a three point hitch apparatus 4 on the rear of powered vehicle, such as a tractor. The frame 10 is rectangular so that the center is open to permit clearance for a power take off. A ball socket 20 is mounted on a horizontal lower frame beam 12 for attachment of a towed vehicle to the powered vehicle. The top of the frame 10 is attached to the tractor by a telescoping arm 60 that can be extended from a retracted to an extended position so that the frame 10 can be tilted or dumping or similar operations. A ball adaptor 34 can be mounted in the center of the mounting frame 10 to permit attachment of a towed implement or vehicle with a male attachment member, such as a ball. A center beam 78 can also be mounted on the center of the mounting frame 10 for supporting and carrying loads.
