Abstract
Presented is an apparatus that includes a unitary frame configured to present three mounting portions spacially separated from one another in a triangular pattern and lying in a common plane to be pivotally connected to and supported by the hitch members of a three-point hitch system mounted on the rear of a tractor and actuable hydraulically to alter the elevation of the three-point hitch system and therefore the unitary frame of the apparatus. The apparatus facilitates connecting different types of agricultural and other trailer-type implements to the tractor and for selectively varying the size of the apparatus to accommodate three-point hitch systems of different sizes.
