Komatsu D80 expert review

Reviewed by Raul M. on April 22, 2026

Overview

The Komatsu D80 (1978–1996) is a traditional crawler dozer designed for grading, land clearing, and general earthmoving tasks. It delivers a 21,550 kg operating weight, a 3 m blade width, and a direct drive system, providing steady and practical pushing performance on demanding job sites.

Expert rating: 3 stars

Pros Strong machine weight and simple direct drive setup for dependable dozing work.
Cons Older machine platform with less refinement than newer crawler dozers.

Performance & Efficiency

The 21,550 kg operating weight, 3 m blade, and direct drive layout give the D80 steady pushing power for grading, clearing, and general site earthmoving, while the tracked undercarriage supports traction and stability on rough ground.

In Comparison

Cat D7: More modern dozer with better refinement and broader jobsite appeal.
Komatsu D70: Smaller dozer better suited to lighter contractor work.
Komatsu D80: Better suited to buyers wanting heavier weight, mechanical simplicity, and practical push performance.

Final Verdict

Rated 3 stars, the Komatsu D80 offers solid crawler dozer performance within the AED 280,000–390,000 range.
