Great machines my cousin in law operates a 275 and a 375 says they will out push and out rip a kitty all day long cats are still a great machine thought. The Komatsu Dozers are so much better looking than the Cat dozers. The Japanese know how to build a awesome and beautiful dozer!!  Something about the dirt rolling in front of that blade is just memorizing, that's a beast of a machine! Biggest dozer iv ran is a D8R.  the 375 is a fantastic machine to operate. in my experience it exceeded the ability of the similarly sized d10 after having the opportunity to operate both in the same atmosphere doing the same tasks. I also thought the cab was more comfortable in the 375 that. the d10 and the ripping ability of the komatsu would run circles around the d10. that's just my opinion though.  Pushing off waste Its all lose and they can slot doze what about 1.5x the capacity of the blade Anyway, nice shiny new BEAST that will surly serve 10's of thousands of hours....
