What model is this crawler?

[D9Mike]

Hello,I ran across this crawler in a scrap yard and think it is either a Cletrac or an Oliver.It has a 6 cylinder diesel and looks to be a pretty straight machine that was well taken care of at one time.I think the engine has water in it.The undercarriage looks decent.What year and model is it? What is it worth? I am new to the forum.The picture link is below.Thanks in advance.Mike

That is a DDH. I would say it is about a 1953 or '54 because of the air assist steering. I think 1952 or '53 was the first year for that. It looks to be in decent shape. I have one Identical to it.

I think I saw that tractor on ebay a while ago. The engine was stuck if I remember right. It would make a nice tractor.

Yes it is a DDH, a 70 hp tractor.  The air steering is a nice option. Looks like it has the internal transmission filter so that would make it a 1951 or later
