![]() ![]() They do not sell any parts for it, you have to buy the entire unit. ![]() When one of my hydraulic pumps stopped working, they wanted $25,000 for a replacement. They also have a terrible policy of only supply entire units to fix a small broken part. I've had to contact salvage yards for mine on several occasions and pay ridiculous amounts for what I got. They are more for the residential pad builder getting a lot ready for a house in some neighborhood.Ĭase has been rather poor at maintaining parts. The smaller ones, like the Komatsu, wont be very good at getting much done. I would think something like the D5 in the low 100 hp range is going to give you the best of both worlds. To maintain it, smaller is better because you have more control for finish work. To build your track, I would think you would want as much HP as you could afford. Took him forever, and the piles he created are still there. My neighbor had a guy with a D4 clear his fence line and that was also too small for what he was doing. The 450 was just too small to clear the land or dig into the dirt. HP and weight make a huge difference when trying to move material, or break through the hard crust of the ground in summer. They are night and day different in size from each other, but I learned a few things from each of them. If you want to speak to our head mechanic, or other personnel regarding the D65EX-12, then call me at (250) 785-2916 (Canada).I have a Case 1550 dozer and before that I rented a Deere 450G dozer. 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: ![]()
