Strength and performance

When you need a versatile mining dozer that can go from ripping solid rock to cleaning up around the dragline, the Komatsu D475A-8 is a solid choice. Using an automatic lockup torque converter, the D475A-8 combined power and speed is designed for high production with minimal fuel consumption.

  • Up to 10% productivity increase over previous models
  • Over 11% more engine power in the reverse direction versus the forward direction
  • 10% reduction in fuel consumption with automatic transmission with lockup torque converter compared to operation in manual gearshift mode

Features and benefits

Lockup torque converter

Lockup torque converter

Engineered for exceptional production. Komatsu’s lockup torque converter produces a more efficient transfer of power to the driveline, designed to help decrease cycle times and increase production.

Low undercarriage design

Low undercarriage design

Equipped with a low drive undercarriage designed to help reduce wear and tear on your machine while still delivering comfort and stability. Minimal moving parts to help maintain high levels of traction and production when dozing and ripping.

Structural improvements

Structural improvements

The D475A-8 features a more reliable mainframe with twice the design life over previous models, designed to reduce maintenance costs and machine downtime.

Blade auto-pitch

Blade auto-pitch

Designed to increase dozing efficiency while reducing operator efforts with blade auto-pitch mode.

Ripper auto-return

Ripper auto-return

The new, ergonomic ripper control lever incorporates an auto-return function designed for less fatiguing operation, automatically raising the ripper after momentarily actuating the control lever while the machine is in reverse.

Track shoe slip control

Track shoe slip control

Track shoe slip control automatically controls engine speed and minimizes slip during ripping operation, so your operator doesn’t have to.

Operator comfort

Operator comfort

Designed to maximize operator comfort and productivity with thoughtful design enhancements like an upgraded cab suspension and palm control joysticks.

Single blade linkage

Single blade linkage

Significantly reduced blade side sway with an all-new blade support structure. The new support structure has fewer maintenance points with enhanced visibility over previous models.

Maintenance features

Maintenance features

The D475A-8 is engineered to minimize planned downtime and make maintenance efficient with features such as centralized greasing points, ground-level fill/evac service center and battery and starter isolators with lockout tagout functionality.


Technology that works as hard as you do

Select continent

ProVision

The ProVision Machine Guidance System helps dozer operators work with enhanced efficiency and according to plan. This promotes reduced rework, and can help lessen or eliminate reliance on manual survey methods. High-precision global navigation satellite system (HP-GNSS) positioning enables the system to continuously track the true movement of the dozer in relation to its final surface design, keep-out zones, and other equipment units in the vicinity.
