2025 Komatsu Dozers D375A-8

Strength and performance

Whether you are looking to keep blasting, loading and dump areas clean, or construct and maintain haul roads, dozers have a direct impact on your fleet’s productivity. With new mainframes featuring twice the design life over previous models, Komatsu mining dozers are engineered to be powerful and durable.

Features may include:

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
  • 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
  • The D375A-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
  • Designed to increase dozing efficiency while reducing operator efforts with blade auto-pitch mode.
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.
