Cat D10 vs Komatsu D155A-6: which mining dozer suits your pit?
The Cat D10 is the much bigger machine, at 603 HP against 360 HP on the Komatsu D155A-6, with close to double the blade capacity and more fuel for long shifts. The D155A-6 is still a capable mining dozer in its own right, with two ripper choices: a 3-shank multi-shank ripper for wider coverage, or a giant single-shank that digs to 1,370 mm for deeper breaking. Its minimum turning radius of 2,140 mm also helps it work in tighter pit corners.
Choose by the scale of your mine. For operations just moving beyond construction-class equipment into mining-class dozing and ripping, the D155A-6 is a practical starting point. For sustained, high-volume overburden removal on bigger mines, the D10's larger blade and elevated final drives are built for continuous, high-hour duty. Both are mining dozers in our dozer range. New to dozers? Read the bulldozer guide first.
Cat D10
Pros:
Far more powerful at 603 HP with almost double the blade capacity
Larger 1,269-litre fuel tank for longer shifts
Elevated final drives keep the drivetrain away from ground-level impact
Narrower overall body than the D155A-6
Cons:
Much heavier at 70,256 kg, needs mining-scale transport and site infrastructure
No published minimum turning radius or ground bearing pressure figure
Komatsu D155A-6
Pros:
Two distinct ripper choices: a wide 3-shank multi-shank or a deep-digging giant single-shank at 1,370 mm
Tighter minimum turning radius of 2,140 mm, useful in confined pits
Lighter at 41,700 kg, a practical step up from construction-class dozers
Optional high-capacity AC cabin
Cons:
Much less powerful at 360 HP with a smaller 9.4 m³ blade
Smaller 625-litre fuel tank than the D10
Wider overall body than the D10 despite being the smaller machine
Pros:
Cons:
Closing Recommendation
The Komatsu D155A-6 suits mining operations just stepping up from construction-class dozers, since its ripper choices and tighter turning radius make it practical for quarry and opencast work. The Cat D10 suits larger mines pushing heavy overburden day after day, where its bigger blade and elevated final drives are built for continuous, high-hour duty. So match the machine to your work: Komatsu D155A-6 for quarry and opencast operations moving into mining-class equipment, Cat D10 for large-scale overburden removal on bigger mines.
Cat D10 Vs Komatsu D155A-6 Dozer Price, Technical Specifications & Features
The Cat D10 is a 70.3-tonne mining crawler dozer powered by a 603 HP engine. Its 18.5 m³ blade provides the material-moving capacity required for large overburden operations. The machine sits between the D8 and D11, giving mining operators a substantial step up without choosing Cat's largest crawler dozer. Ground clearance reaches 725 mm, helping on rough pit floors where loose rock is common. Ripper choices include a single-shank configuration with a pin puller and a 3-shank multi-shank setup. An optional counterweight adds force where harder breaking work requires it. Fuel capacity reaches 1,269 litres, supporting long working shifts. The D10 suits coal, iron ore and large-format mining rather than general construction. A mining company handling high-volume overburden can consider this dozer machine when the D8 no longer provides sufficient blade capacity. The larger operating weight supports heavier pushing work, while the available ripper configurations provide different approaches to breaking. Buyers can match the setup to the material and working conditions. The D10 offers a large mining crawler dozer option below the D11 while still providing substantial production capacity for major mining operations.
The Komatsu D155A-6 is a 41.7-tonne mining crawler dozer powered by a 360 HP engine. Its 9.4 m³ blade provides substantial material-moving capacity, while two ripper configurations give operators different approaches to breaking. The 3-shank multi-shank ripper reaches 900 mm, whereas the giant single-shank reaches 1,370 mm for deeper work. SIGMADOZER, Semi-U and Full-U blade configurations are available for different applications. Ground bearing pressure is 115.8 kPa, with 500 mm of ground clearance for rough mining surfaces. A 625-litre fuel tank supports full-shift operation. The D155A-6 is the smallest of Komatsu's listed mining crawler dozers and sits below the D275A-5R, D375A-6 and D475A-5E0. Quarry and opencast operations are suitable applications. Pricing is available on request from mining dozer dealers. A mining contractor moving beyond construction-class equipment can consider this dozer machine when greater pushing and ripping capacity becomes necessary. The two ripper configurations allow buyers to match the setup to the ground. Its operating weight keeps it below the larger Komatsu mining machines. For operators entering mining-class dozer ownership, the D155A-6 provides a practical starting point before moving into higher-capacity equipment.

Questions buyers ask about the Cat D10 vs Komatsu D155A-6
Ans.
The Cat D10 is far more powerful. It runs a 603 HP engine against the D155A-6's 360 HP, with almost double the blade capacity at 18.5 m³ against 9.4 m³. The D10 also carries more than double the fuel, at 1,269 litres against 625 litres.
Ans.
The Komatsu D155A-6 has a published minimum turning radius of 2,140 mm, useful in tighter pit corners and around stockpiles. The Cat D10 does not list a turning radius figure, so buyers working in confined pits should check this with their Cat dealer before choosing.
Ans.
The Komatsu D155A-6 offers two distinct ripper options. Its 3-shank multi-shank ripper covers wider ground, while its giant single-shank digs to 1,370 mm for deeper breaking. The Cat D10 also offers single-shank and multi-shank rippers, with CapSure hammerless tips and an optional counterweight.
Ans.
The Komatsu D155A-6 is the more practical entry point. It sits below the D10 in scale, so a quarry or opencast operation moving beyond construction dozers gets mining-class pushing and ripping power without the size and cost of the D10.
Ans.
The Komatsu D155A-6 is actually the wider machine, at 4,130 mm against 3,311 mm on the Cat D10, despite being the lighter and less powerful dozer. This is worth checking against haul road widths and transport clearances before choosing either machine.
