Komatsu D75S expert review

Reviewed by Rizwan R. on April 22, 2026

Overview

The Komatsu D75S (1979–1987) is a heavy crawler loader designed for bulk material handling, land clearing, and rough loading tasks. It delivers 149.14 kilowatt engine power, a 2.22 cu m bucket, and a 3.2 m dump height, providing solid production capability on difficult ground conditions.

Expert rating: 3 stars

Pros Strong traction and stable bucket performance on rough and uneven job sites.
Cons Older machine platform with slower travel and less refinement than newer loaders.

Performance & Efficiency

The 149.14 kilowatt engine, 2.22 cu m bucket, and 3.2 m dump height give the D75S practical loading power for bulk earthmoving and site material handling, while the tracked undercarriage improves traction on softer or uneven ground.

In Comparison

John Deere 655: Practical crawler loader with comparable site-loading ability.
Komatsu D70: More focused on dozing rather than dedicated loading work.
Komatsu D75S: Better suited to buyers wanting tracked loading performance and stronger bucket-focused capability.

Final Verdict

Rated 3 stars, the Komatsu D75S offers practical crawler-loader performance within the AED 58,000–110,000 range.
