Reg, The lift arms of the tractor are supposed to fit into a slot on each side of the quick hitch and be pinned in place. The tractor lift arms will not fit into the slots in the hitch that they are supposed to fit into. In order to allow the item to fit, the slots (opposite each bottom hook of the quick hitch) will have to be widened about 1/8". This can be done by cutting the metal plate forming one side of each slot and moving that piece of plate outward at least 1/8 and welding it into the new position. Correct registration must be preserved so that the holes in each of the plates forming the slot remain aligned so that the pin will fit thru. Either this mod, or grind down the width of the thru hole in the tractor lift arm balls! That would compromise your tractor.
