Need info on d-2

My book shows early 1953 . That is a neat unit , don't come any better than that .and a Winch to Boot !! Good luck with it . LJ

Looks pretty nice--good grousers, electric start pony, winch,etc. I don't know if that serial # is late enough for the extended clutch housing where you can replace the clutch without pulling the engine. The larger size front idlers, i think 23 1/2" are great for keeping the nose from diving down when you lift the blade. They are usually solid idlers vs the spoked that you have.

In the 2nd photo, the track adjustment looks pretty far out?
Other than that, it doesn't seem too beat up for a tractor that obviously has been used to skid logs.

Nicely equipped! I may use that Roll cage as a model when I build mine.

I doubt that cage could withstand a roll but should be good for branches and widow makers.
