Abstract
A sway limiting device for a three-point hitch on a tractor having reversible sway limiting blocks. The sway limiting blocks in one position permit sway of the hitch and implement under field operating conditions and in another position eliminate sway of the hitch throughout the fulllift range of the hitch by interchanging the right and left-hand sway blocks and using the reverse side of the sway blocks.
