Running a dozer in good dirt is just about the most fun you can have with your clothes on, and a sweet running TD25C was a pleasure to be on. They were powerful, fast, easy to use with the two-speed steering, and they had a nice engine sound. At the time, the D8H Cat was just about at the end of it's run as was the AC HD21, also a nice dozer. Yep, not many of the old girls around anymore.
I was just thinking, I ran a TD25B in Vietnam with practically no clothes on. One military hat, a pair of cut-off pants, and some Ho Chi Minh sandals is all. Won't count the M14 rifle, the grenades, the rocket launcher, the Claymores, and the K-Bar tucked by the seat.
That was a standard transmission model with a diesel-fuel torque converter and forward-reverser. Pushed a lot of TS24 Euc scrapers with it for a while.
rino1494 is correct, Dressta still makes the TD25 and TD40 models, in Poland of all places. I don't know if they are marketed in the states anymore, and haven't heard if any of the smaller models survived. Komatsu did market some of the loaders and small dozers for a while. The TD25G was supposed to be the cats meow, but the change to the Cummins engine and other so-called improvements didn't work out well. Dresser made some of these in Poland and they were disasters. They actually used some parts they took back in from the Polish Army on some of these machines, the olive drab paint was still there under the new coat of yellow. I had one on a job in Colorado for a while and never could keep it running, was a new problem every day. Original dealer eventually took it back and I believe they used it for parts in Missoula.
