A powered adjuster for a three-point hitch upper arm includes a housing adapted for rotatably supporting a drive hub having opposite ends with oppositely threaded openings for receiving the oppositely threaded connection members of a three-point hitch upper arm. A motor is supported on the housing and a drive connection is provided for rotating the drive hub in response to actuation of the motor. Finally, a coacting guide mechanism is provided on the housing and one of the connections members for preventing relative rotation between the housing and connection member while permitting relative axial sliding movement therebetween to accommodate powered extension and retraction of the upper arm by the adjuster of the invention.
