Komatsu D155A-6 vs Komatsu D375A-6: which mining dozer fits your production scale?
The Komatsu D155A-6 is far smaller than the Komatsu D375A-6, at 360 HP against 610 HP, with a 9.4 m³ blade against 18.5 m³. It turns in a much tighter radius of 2,140 mm against the D375A-6's 4,200 mm, and its ground bearing pressure is lower too, so it sinks less on soft ground despite being the lighter machine. The D375A-6 carries roughly double the blade capacity and nearly double the fuel tank at 1,200 litres, built for a much bigger production step.
Choose by production scale, not just size. A contractor moving beyond construction-class equipment into mining-class ownership gets a manoeuvrable, entry-point machine in the D155A-6, useful where pit corners are tight. A large opencast mine already running heavy overburden volumes needs the D375A-6's bigger blade and longer shift range. Both are mining dozers in our dozer range, and our bulldozer guide can help size a dozer to your site's output.
Komatsu D155A-6
Pros:
Turns in a much tighter radius of 2,140 mm for confined pit corners
Lower ground bearing pressure, sinks less on soft ground despite being the lighter machine
Two ripper choices, multi-shank or giant single-shank
Practical entry point into mining-class dozer ownership
Smaller frame is easier to place and manoeuvre on site
Cons:
Far less powerful at 360 HP against the D375A-6's 610 HP
Smaller blade at 9.4 m³ against 18.5 m³
Smaller fuel tank at 625 litres against 1,200 litres
Not sized for the largest opencast overburden volumes
Komatsu D375A-6
Pros:
Far more powerful at 610 HP with an 18.5 m³ blade
Nearly double the fuel tank at 1,200 litres for longer shifts
Choice of giant single-shank or 3-shank parallelogram ripper
Automatic planetary powershift with lockup converter and selectable working modes
Sized for large opencast mines running heavy overburden volumes
Cons:
Much wider turning radius at 4,200 mm, less nimble in tight pit corners
Higher ground bearing pressure, sinks more on the same soft ground
Roughly 30 tonnes heavier, needs more haul-road and transport planning
Pros:
Cons:
Closing Recommendation
The Komatsu D155A-6 suits a contractor moving beyond construction-class equipment into mining-class dozer ownership, where a smaller, tighter-turning machine is enough to get the job done. The Komatsu D375A-6 suits large opencast mines that need much greater blade volume and fuel range for sustained overburden dozing. So match the machine to your work: Komatsu D155A-6 for a first step into mining-class ownership, Komatsu D375A-6 for large-scale opencast production.
Komatsu D375A-6 Vs Komatsu D155A-6 Dozer Price, Technical Specifications & Features
The Komatsu D375A-6 is a 71.6-tonne mining crawler dozer with a 610 HP engine. It sits between the D275A-5R and D475A-5E0, providing a substantial production step without moving directly to Komatsu's largest model. Blade capacity reaches 18.5 m³ for heavy overburden movement. Operators can choose between a variable giant single-shank and a 3-shank multi-shank ripper. The single-shank configuration focuses on deeper breaking, while the multi-shank option provides broader coverage. Tractor-only ground bearing pressure is 108 kPa and rises to about 145 kPa in full operating trim. Ground clearance is 610 mm, helping the machine work across rough pit floors. A 1,200-litre fuel tank supports long shifts. Coal and mineral mining are the main applications. Mining companies handling large overburden volumes can consider this dozer machine when the D275A-5R no longer offers enough capacity. Its operating weight provides substantial pushing capability without reaching the scale of the D475A-5E0. Buyers can match the ripper configuration to the material being worked. The D375A-6 is suited to mining operations where blade volume, pushing force and ripping capability all form part of the regular work cycle.
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.

Ans.
The Komatsu D375A-6 is far bigger. It has 610 HP against the D155A-6's 360 HP, an 18.5 m³ blade against 9.4 m³, and roughly 30 tonnes more operating weight.
Ans.
The Komatsu D155A-6 turns tighter. Its minimum turning radius is 2,140 mm against the D375A-6's 4,200 mm. That is a big difference in confined pit corners.
Ans.
The Komatsu D155A-6 sinks less. Its ground bearing pressure is lower than the D375A-6's, even though it is the smaller and lighter machine.
Ans.
The Komatsu D375A-6 holds nearly double the fuel, at 1,200 litres against the D155A-6's 625 litres. That matches its much larger size and supports longer shifts on big sites.
Ans.
The Komatsu D155A-6 fits that step better. It is smaller, turns tighter and gives a practical way into mining-class work before a fleet owner needs the D375A-6's much bigger production capacity.
