Understanding your machine’s data and analytics Smart Construction Retrofit Kit and Pilot If you want to speak to our head mechanic, or other personnel regarding the D65EX-12, then call me at (250) 785-2916 (Canada).Specialist Komatsu Genuine Undercarriage Solutions One caveat, if you run something to failure the repair bills will likely be higher than a Cat's. Can't honestly say if that's true with U's or Semi-U's. I'm talking Straight, or as we use here, Angle Blades. Normally an equivalent Komatsu will move significantly more dirt than a Cat, and cut where a Cat will have to rip, as long as the blade is one designed to Komatsu specifications. I suggest buying a well maintained used (for their greater depreciation) and go out & make money in circles around those who want to pay the premium for Cat. Probably the most trouble free dozer we have owned in over 40 years of operation. We have not rebuilt or replaced a fuel pump, I think we have replaced one turbo and a few alternators, maybe a starter or two. Their reliability has not even required anything much in the way of rebuilding, we have not rebearing anything other than the aforementioned planetary. The only major component failure we have suffered is one planetary, due to the failure of the oil seal and a lack of attention by the operator. We have 5 D65EX-12 in our fleet, with up to 16,000 hours on them. I'd say the -12 would be the best bang for the buck if you're not taking resale value into consideration. The performance is the same as the the -15, with far less electronic nonsense. But, if I were looking to BUY one, I'd see if I could get a nice PX-12 (or in your case, EX-12). A lot of the other operators prefer the Komatsu's for everything, though. ![]() My choice to operate would be the Komatsu for strictly bulk pushing, the Deere for everything else. All of them break down from time to time. The Deere has the nicest cab and the best visibility, followed by the Cat which is trailed by the Komatsu. The Deere is low and wide and will hang on a slope better than the narrower Komatsu, but the Komatsu is better than the top heavy Cat. The Deere is far more nimble, and feels like a fighter plane while the other two are lumbering bombers. For all out push, the Komatsu has a bit more grunt than the Cat, which has a bit more grunt than the Deere. I agree with Dozer Fan's assessment, and let me add some thoughts from an operator's standpoint. The Komatsu might have a little more power but it's so close, it really depends on which motor you got of the assembly line. The Komatsu is rated at 190 HP while the Cat is at 185HP. 70-100 to be the norm though it depends on how "hot" or "turned up" the machine is. The equivelent D6R is going to set you back at least 70K and probably more like 90K.īoth machines like the diesel. If you just want a machine for occassional usage, you can pickup a D65EX with around 7K hours for 45K. Keep in mind however that I put 2K+ hours/year on these machines. But for me from a cost standpoint it's hard not to go with a Cat. ![]() Most of my operators like running the Komatsu's better than the Cats. I have had some problems with the pumps ($30K) on 3 of them (all with close serial numbers BTW) at around 6-7K hours although I have 2 Komatsu's with 9K and 11K that I have had absolutely no problems with. With that being said, Komatsu makes a great dozer. The intial cost of the machine is higher but, the maintence costs are lower and the resale value is higher. The Cats are much better dozers in the long run. I own own a company with a fleet of 12 dozers: ![]()
