I have a BDH to move down the road. I don't know how to attach pictures, but I have some. Diesel engine. About 10,000 pounds, I reckon. Has huge winch on the rear. Cage over operator. Starts and runs but has water leak. Could be as simple as a loose gasket. Had the head off a couple of years ago to look it over and found some cracks. Brazed them up. Reinstalled, started it up, noticed leak, shut it down and never revisited it. Crawler has a big blade up front (hydraulic). Blade and winch both work fine. I think it is a 1948 model. I have a photocopy of the manual. One missing shoe, but I have one to install. Crawler starts and runs and can be driven onto a trailer but I wouldn't run it longer than that before addressing the water leak.
Located a bit east of Seattle. I'd keep it but I just don't have any real need for a dozer, so I never get around to addressing the water leak. $1100.
