Good luck !
Looks like the steering clutches are gone/rusted solid. Tell tale sign is the handles are way back.
Just a consideration to check. At least parts are available for those.
Everything's available to get it running again. The belt pulley can be repapered by paperpulleys.com. Steering from General Gear, other nicknacks from Florin, and OEM from Cat.
That's a very straight looking tractor, wouldn't mind that as a project. You can swap out the pony while repairing yours.
I'm going to pass on this, too many irons in the fire right now.
If anybody is interested let me know and I will pass on the contact info of the guy who has it (co-worker)
I might be interested please PM me know the info. Thanks
