Komatsu WA90-6 overview

Komatsu WA90-6 features overview

Walk-Around

Small but powerful! Our new Dash 6 compact wheel loaders further improve the features and benefits of their successful predecessors. No matter what the job is, the new models are more flexible, more versatile, and deliver top class performance. Compact and safe, comfortable and reliable, these powerful Dash 6 machines reflect Komatsu’s long experience in wheel loader manufacturing, and the company’s ongoing commitment to both security and a cleaner environment.

Visibility and Comfort

Large glass surfaces and the standard heated rear window offer great visibility of the surrounding area – no matter the job. Optimal noise insulation, easy-to-reach buttons and adjustable vents complete a comfortable work environment.

A reliable partner

Komatsu compact wheel loaders are known around the world for their robustness and durability. All maintenance and service can be done easily and quickly thanks to their unique tilting cab. The engine hood can be opened widely for a quick daily inspection, the electric equipment is well protected behind a maintenance cover inside the cab, and the easy-to-clean radiator is conveniently accessible.

Engine / Powertrain / Drivetrain

Full power for the highest performance

Environmentally friendly, the new Komatsu ecot3 engine is part of a long Komatsu tradition of efficiency and reliability and meets EU Stage IIIA & TIER III emission regulations. As the engine is optimised for tough construction applications it delivers high torque even at low rpm. With high rimpull and enough reserves even in the most difficult ground conditions it still features a low fuel consumption.

Transmission and Fuel Capacity

A fully automatic, hydrostatic transmission sends power to all four wheels while the large 140 l fuel tank guarantees long and uninterrupted working hours.

Operator's cab

Highest safety

The low centre of gravity enhances stability and compact dimensions ensure an exceptional all-round visibility, resulting in maximum operational safety. Standard safety features such as the ROPS/FOPS cab, back-up alarm, reversing light and large mirrors add up to make the WA90-6 a truly safe machine.

Bucket and Ground Engaging Tools

High productivity

If you’re looking for a small machine with huge performances, then this compact wheel loader is made for you. With its amazing lifting and dumping height and superior breakout power, it works like a bigger machine. When equipped with one of Komatsu’s extremely robust and easy to fill buckets, or with pallet forks, high payloads guarantee maximum productivity.
