2005 Caterpillar D6R XL Series II dozer, this unit has 15,516 hours on meter, but despite the big number it has been taken good care of, took it to the service regularly, undercarriage like new, very good blade(single-tilt, semi-U, 10' 4"W) Machine also has working a/c and heat, C9 engine, powershift 3F-3R transmission. The dozer is ready to work, without any malfunctions. Everything is serviced and functional. I'm thinking $52,000 is a fair price, but there might be a little wiggle room.
