A three-point hitch mountable to the front frame of an agricultural tractor includes a main backing member, an upper hitch-point anchor bracket having four sets of securing pin anchoring positions that is welded to the main backing member, a pair of spaced-apart pivot anchors welded to the main backing member, an A-frame assembly pivotably installed between the pivot anchors, and a hydraulic cylinder which raises and lowers the A-frame assembly operably coupled to one of the middle sets of pin anchoring positions and the A-frame assembly. An implement can be connected to the upper-most anchoring position and the distal ends of the A-frame assembly. The three-point hitch can be converted to a ball hitch by re-pinning the hydraulic cylinder to the uppermost anchoring position, raising the A-frame assembly about ninety degrees and pinning it to the anchor bracket.
