Say, I'll mention the Achilles' heel on that machine. its the Sherman
set up/step down tranny. There is no way to add oil to this tranny
located under the steering column. It runs dry and the front bearing
and main tranny shaft burn out. No more parts available from Ford.
Long wait at any salvage yard for a replacement tranny priced at $500
(eight years ago)

Luckily, I knew a machinist with three days to spare after mine burned
up and locked the tractor wheels solid.

If you have yours apart give this unit some long overdue attention.
