Hello.. Im in the market for a small dozer... Been looking at a Komatsu D31P-20 in great shape with new undercarriage.. However I'm not finding very much info about these 31 series dozers anywhere... I'm looking for some real-world experiences... Anybody else own or run one of these before? How do they compare to Case/JD 450 size machines? My use is for personal/residential use around the estate... putting in a driveway here and there, flattening out some hillsides, moving some trees around... Do you think this D31P-20 would be adequate for that? Thanks...
The P in the model number indicates this is a low ground pressure machine. I don't remember where the dash 20 fits in but all I worked on had a six cylinder engine that ran as smooth as silk. There were no torque converters in those machines but they did use a power shift transmission. These machines are pretty basic in design and not hard to work on. Parts are available from your Komatsu dealer. Undercarriage as I recall was pricey and only available from the dealer but that might have changed some by now. They are about the same size and horsepower as the 450 Deeres of that time frame. Good Luck!
go back 8 pages.. or use the search function... there's a thread there on them
