Komatsu WB146 expert review
:quality(50)/60955/11289297-4fd3-4db8-aa77-83a15321cf02.jpeg)
Overview
The Komatsu WB146 (2006–2013) is a practical backhoe loader designed for excavation support, loading, trenching, backfilling, and general construction work. It delivers 66.07 kilowatt net power, 406.74 Nm torque, a 7,300 kg operating weight, and a 150.26 liter fuel tank, giving it a balanced setup for daily contractor use.
Expert rating: 5 stars
Pros Strong torque, practical operating weight, and good fuel capacity for daily site work.
Cons Larger dimensions need more care in tight access areas.
Performance & Efficiency
The WB146 produces 66.07 kilowatt net power and 406.74 Nm of torque, giving it useful strength for loading, trenching support, backfilling, and daily site work. Its 7,300 kg operating weight gives it good working stability, while the 150.26 liter fuel tank supports longer operating periods between refueling stops.
In Comparison
Komatsu WB140: Heavier backhoe loader with a larger footprint and stronger weight on the ground.
Komatsu WB142: Lighter option with easier handling, but lower power and torque.
Komatsu WB146: Balanced choice for buyers who want stronger torque than the WB142 without stepping into the heavier WB140 profile.
Final Verdict
Rated 5 stars, the Komatsu WB146 offers dependable power, useful torque, and balanced backhoe loader performance within the AED 180,000–270,000 range.
