A friend has one where a older gentlman ran it with the rear end bolts loose, no oil in the rear end.
It is a later series, I kinda heard 4 mentioned if that sounds correct. It has the Eagle hitch. Freight would probably make long miles to costly.
Any idea where to look for a fence row unit? The local salvage yards would probably make the parts cost more than the value of the tractor in mint condition.
