Komatsu WF450 expert review
:quality(50)/55272/8c2d1d6b-e9a4-40d8-9825-964e2a331151.webp)
Overview
The Komatsu WF450 (1991–1996) is an older heavy crawler dozer designed for pushing, grading, clearing, roadwork, and heavy earthmoving support. It delivers 194.03 kilowatt gross power, uses an SA6D125E-2 engine, and carries a 26,000 kg operating weight, giving it strong traction and stability for demanding ground work.
Expert rating: 3 stars
Pros Strong 194.03 kilowatt gross power and 26,000 kg operating weight for heavy pushing work.
Cons Older machine age makes undercarriage, blade, hydraulic, and engine condition critical.
Performance & Efficiency
The 194.03 kilowatt SA6D125E-2 engine gives the WF450 practical strength for dozing, clearing, grading, and heavy site preparation. Its 26,000 kg operating weight helps with traction and blade control, while the crawler platform makes it more suitable for loose, rough, or uneven ground than a wheel dozer.
In Comparison
Komatsu D155: Stronger-known Komatsu crawler dozer with a broader heavy-earthmoving reputation.
Cat D8: Popular heavy dozer with strong support and resale confidence.
Komatsu WF450: Capable for pushing and grading work, but condition and maintenance history carry more weight.
Final Verdict
Rated 3 stars, the Komatsu WF450 is a capable older crawler dozer within the AED 250,000–380,000 range. It offers solid pushing power, but clean undercarriage condition and a clear service history are essential before purchase.
