A three point hitch assembly for attachment to the rear of a powered vehicle, such as a four wheel drive vehicle, for trailing an implement. The three point hitch assembly is pivotal in a horizontal plane to allow for decreased turning radius when the implement is rendered operable, and vertically adjustable for positioning the implement. The three point hitch assembly includes a fixed planar plate mounting device for removably securing the three point hitch assembly to the rear of the powered vehicle, and a pivotal main frame mounting a rotating planar base and adapted for pivotal movement on the fixed planar plate. The pivotal main frame includes an L-shaped member, fixedly secured to the rotating planar base, a transverse arm having a pair of free ends, with each end pivotally mounting a lifting arm, where a free end of each lifting arm includes a mounting device for removably securing the implement. Additionally, there is included at least one adjustable leveling arm.

[ What is claimed is:] [1.]1. A three point hitch assembly for connection to the rear of a powered vehicle for trailing an implement, where the three point hitch assembly is pivotal in a horizontal plane to allow for decreased turning radius when said implement is operable, and vertically adjustable, said three point hitch assembly comprising:a.) a fixed planar plate mounting means for removably securing said three point hitch assembly to the rear of said powered vehicle; and,b.) a pivotal main frame mounting a rotating planar base and adapted for pivotal movement on said fixed planar plate, said pivotal main frame further including,(i.) an L-shaped member, fixedly secured to said rotating planar base, having a first leg arranged parallel to said planar base, and a second leg extending essentially vertically therefrom, where each said leg is provided with plural aligned apertures, and the distal end of said second leg mounts means for raising and lowering said implement;(ii.) a transverse arm having a pair of free ends, each said end pivotally mounting a lifting arm, where a free end of each said lifting an includes means for removably securing said implement;(iii.) at least one adjustable leveling arm extending between at least one said lifting arm and a link assembly;(iv.) an adjustable link member extending between said link assembly and a selected position with one of said aligned apertures; and(v.) means extending between said link assembly and said raising and lowering means to operatively adjust and position said pivotal main frame.
