I just purchased a 77 with a standard rear end and a row crop narrow front end. The tractor was used in the woods to skid logs and the owner broke the original front end off and broke a chunk out of the front casting. When he could not find the parts to fix it like original he put a row crop front casting and a narrow front end on it. The tractor runs great but looks kind of funny. If anyone is looking for a good standard rear end with wheels and tires I would like to trade for a row crop rear end of equal value. Thanks. <!-- s:roll: --><img src="{SMILIES_PATH}/icon_rolleyes.gif" alt=":roll:" title="Rolling Eyes" /><!-- s:roll: -->
