Cat D11 vs Komatsu D275A-5R: which mining dozer fits your pit?
The Cat D11 is the far bigger machine, built for the largest opencast mining operations, while the Komatsu D275A-5R is a mid-size mining dozer sized between the common 350 HP class and the true mining giants. The D11 runs an 850 HP engine against the D275A-5R's 449 HP engine, and its operating weight of about 104,236 kg is roughly double the D275A-5R's 50,850 kg. Its 34.4 m³ blade also moves far more material per pass than the D275A-5R's 13.7 m³ blade.
Choose by the size of your pit and your production target. The Cat D11 fits the biggest coal and metal mining operations that need sustained bulk dozing, heavy ripping and dragline or shovel support, and it carries more fuel and far more automation, including semi-autonomous dozing options. The Komatsu D275A-5R fits medium-scale mining and large earthwork where the production target sits between a smaller machine and a true mining giant, and it remains easier to move around a working pit. Both are mining dozers in our dozer range; new buyers can read the bulldozer guide first.
Cat D11
Pros:
Far more engine power at 850 HP against the D275A-5R's 449 HP
Bigger blade at 34.4 m³, more than double the D275A-5R's 13.7 m³, for higher volume per pass
Larger fuel tank at 1,800 litres, for longer shifts between refuelling
More ground clearance at 798 mm, helps on rough pit surfaces
Extensive standard and optional automation, including VIMS, Automated Blade Assist and semi-autonomous dozing where one driver can run several machines
Standard automatic climate control cabin
Cons:
Much heavier at 104,236 kg standard, so transport and site moves cost more
Sized for the largest opencast pits only; it cannot be scaled down if production needs fall later
Wider overall commitment, since rebuild facilities, support contracts and capital cost all scale up with the machine
Komatsu D275A-5R
Pros:
Lighter at 50,850 kg, easier to reposition and transport than the D11
Sits in the gap between the common 350 HP class and the largest mining giants, matching production more closely to cost
Slightly faster in reverse at 14.9 km/h against the D11's 14.7 km/h
Two ripper choices, a variable giant single-shank ripper reaching 1,420 mm depth or a 3-shank multi-shank, for different ground conditions
Lower fuel and service fluid needs, matching its lighter working duty
Cons:
Less engine power at 449 HP against the D11's 850 HP
Smaller blade at 13.7 m³, moves less material per pass than the D11's 34.4 m³
AC cabin is optional, not standard like on the D11
Fewer of this size run in India than the classes on either side of it, so drivers who already know the machine and used machines to compare are harder to find
Pros:
Cons:
Closing Recommendation
The Cat D11 suits the largest opencast mining operations that need sustained bulk dozing, heavy ripping and dragline or shovel support, since its size, power and automation are built for that scale. The Komatsu D275A-5R suits medium-scale mining and large earthwork where the production target sits between a smaller machine and a true mining giant, and its lighter size keeps it easier to move around the pit. So match the machine to your work: Cat D11 for the largest opencast mines needing maximum bulk output, Komatsu D275A-5R for medium-scale mining operations that don't need the biggest machine on site.
Komatsu D275A-5R Vs Cat D11 Dozer Price, Technical Specifications & Features
The Komatsu D275A-5R is a 50.9-tonne mining crawler dozer powered by a 449 HP engine. Its 13.7 m³ blade handles heavy cuts, while the 840-litre fuel tank supports long working shifts. A 3-shank multi-shank ripper provides wider breaking coverage, while the variable giant single-shank reaches 1,420 mm for deeper work. The choice allows the same machine to handle different ground conditions. Tractor-only ground bearing pressure is 87.3 kPa and rises to about 118 kPa in full operating trim. Firm mining benches are better suited to this configuration than soft fill. The D275A-5R sits between the D155A-6 and D375A-6 in Komatsu's mining range. Its operating size makes it suitable for quarry and overburden work where construction-class machines are no longer sufficient. Mining contractors can consider this dozer machine when daily production requirements have moved beyond the D155A-6. The two ripper choices provide flexibility between deep breaking and wider coverage. Its blade capacity also supports substantial material movement during each pass. Buyers can therefore compare the required ripping depth, ground conditions and production volume before selecting this model for mining work.
The Cat D11 is a 104.2-tonne mining crawler dozer with an 850 HP engine and 34.4 m³ blade capacity. It is the largest of Cat's three mining dozers listed here. Its size is aimed at large coal and metal mining operations where smaller machines cannot maintain the required output. Ripper configurations include specialty leach-pad and 5-shank coal options. Optional counterweights add force where required, while a rear drawbar with counterweight supports towing and stability on steep grades. Ground clearance reaches 798 mm, helping the machine work around rough pit surfaces. Its 1,800-litre fuel tank supports long working shifts with less frequent refuelling. Large-fleet buyers can consider this dozer machine for high-volume overburden and coal-handling work. The blade capacity allows substantial material movement in each pass. Its operating weight also provides the pushing force required for large mining cuts. General construction is not the intended application at this scale. Buyers considering the D11 should match its capacity to the expected mining volume and ground conditions. For operations requiring the highest capacity within this Cat range, the D11 provides a dedicated mining crawler dozer solution.

Questions buyers ask about the Komatsu D275A-5R vs Cat D11
Ans.
The Cat D11 has far more engine power. It runs an 850 HP engine against the D275A-5R's 449 HP engine, nearly double the output. This extra power lets the D11 push a much larger blade through bulk overburden in big open-pit mines.
Ans.
The Cat D11 moves far more material in one pass. Its blade capacity is 34.4 m³ against the Komatsu D275A-5R's 13.7 m³, more than double. That makes the D11 suited to the highest-volume overburden and coal-handling work, while the D275A-5R fits medium-scale cuts.
Ans.
The Komatsu D275A-5R is easier to move around a pit. It weighs about 50,850 kg against the Cat D11's 104,236 kg, so it is lighter and less demanding to reposition and transport. The D11's much larger size suits fixed, high-volume bulk dozing instead of frequent repositioning.
Ans.
The Cat D11 offers far more automation and monitoring. It includes a multifunction touchscreen, VIMS and Automated Blade Assist as standard, with options for semi-autonomous dozing where one driver can oversee several machines. The Komatsu D275A-5R offers a simpler monitor with a self-diagnostic function.
Ans.
No, the AC cabin on the Komatsu D275A-5R is optional, with heater and defroster. The Cat D11 includes automatic climate control as standard. Buyers who need cabin cooling built in from the start should check this option when ordering the D275A-5R.
