Komatsu D135 expert review

Reviewed by Jed H. on March 11, 2026

Overview

The Komatsu D135 is a classic production bulldozer built during the era of mechanically driven heavy equipment. With 29,800 kg operating weight, a 4 m blade, and a 215.51 kW S6D140 diesel engine, it was designed for quarry work, heavy earthmoving, and large construction site preparation.

Expert rating: 3 stars

Pros Strong pushing power and simple mechanical design that is easier to maintain than modern electronically controlled dozers.
Cons Older design with lower efficiency, comfort, and productivity compared with modern crawler dozers.

Performance & Efficiency

The 215.51 kW S6D140 diesel engine provides strong torque for pushing operations, while the powershift transmission with three forward and three reverse gears allows operators to maintain consistent momentum during heavy dozing cycles.

In Comparison

Komatsu D155A: Larger and more powerful production bulldozer.
Cat D8: Comparable dozer class with strong global parts support.
Komatsu D135: Simpler mechanical platform suited for contractors prioritizing durability over modern technology.

Final Verdict

Rated 3 stars, the Komatsu D135 remains a functional crawler dozer within the AED 170,000–300,000 range, offering dependable pushing power for quarry work and heavy construction.
