We sold the TD25's to the coal mines in western Virginia and eastern West Virginia during the late 60's and 70's from North Carolina Equipment Company in Greensboro, NC It's great to see that a lot of the 25's have been taken care of!

Its an 817 rated at 330 HP. Also it doesn't have a turbo problem every 25 I have been around makes that noise on deacceleration. It is caused mainly by the small intercooler mounted directly to the turbo and it allows it to blow off the boost really fast. The key to getting these old things to run is making sure the exhaust is sealed up really well worth no leaks. The torque converter was kind of a weak spot too.

Bought the same machine last summer but didn't get it home before winter set in. I walked it several miles in reverse but didn't have an opportunity to do any pushing. Was told by the old miners who had been using IH that it was comparable to the cat 9 ( will out push ) on the level ground. Caution to the unaware that the steering is different, most notably when traveling up or down slopes with out a load. This is nice shape for its age, old us Air Force issue. Hopefully I'm able to get it back home to civilization next spring and play with all the levers., neighbors are jealous but didn't offer to buy it as parts could be a bit of a problem. I wouldn't want to have to pay a "yellow" price for what I can do with this machine, and I like cat.

Man that thing sounds like the truck in Duel Hell Yeah

No turbo problem here, just turbo lag when the operator decelarates. Quite a nice machine.

I heard a lot of the old folks say international dozers were tough

Those old 25's would run circles around a D8H. But they wouldn't last as long. I was and am an I H fan even though I no longer own any.

Schönes Video, schöner Maschinensound, danke!

Wish I could see his hands better, Back in the day I was a mechanic for IH, the 25c was a very powerful machine. This one for some reason is very sluggish. The track pads are worn out and this machine would spin those tracks easy. I think it is down on power, the 817 could be set between 250 hp and 495 hp, this one just sounds in need of a good tune.

that is not smoking as bad in this vid.. maybe the turbo is getting loosened up or?

nice condition for 40+ years

what engine?

Blue Ridge Tractor from Benton IL can get parts.

INTERNATIONAL D817 844 Cubic inches displacement.

DT 817B 817 cubic inches 285 HP @1900rpm

needs look at torqueconverter that bady should lite those wore out pads up

what engine is in this? how many hp? im a big international fan

Comparable to a D6?

I mean 817 inches.

Sounds like it has a turbo problem
