Wheel Loaders


Highest in-class productivity - EU Stage V compliant

Designed for maximum operating comfort, the WA900-8 proposes many customer advantages, among which a Modulation Clutch and Variable Traction Control, an Auto Kick Down and an RPM set. Combined with Komatsu’s redesigned extra-large 14,5 m³ bucket and its optimised maximum fill factor, the WA900-8 offers the highest productivity of any wheel loader in its class.

Engine Power
672/901 kW/HP
Bucket capacity
11,5-14,5 m³
Tipping Load
63,61 t.
Operating Weight
116,4 t.
Modulation Clutch system

The Modulation Clutch system gives operators precise control of rim pull, for fast work equipment speeds and a smooth approach for truck loading. The Variable Traction Control system optimises rim pull on all ground conditions, minimises tire slippage and reduces maintenance costs.

Komatsu SmartLoader Logic

On-board Komatsu SmartLoader Logic, a fully automatic engine control, yields precisely enough torque for each work phase, based on the application. By automatically switching between Economy & Power modes it considerably reduces fuel usage, with no loss of productivity.

CLSS hydraulic system

The new generation WA900-8 wheel loader’s hydraulics are also improved with a CLSS hydraulic system that delivers power on demand via the variable displacement piston pumps. It keeps the hydraulic oil cool and increases both your work speed and fuel economy. Fuel savings are further promoted through the Auto Idle Shutdown system and by ECO guidance tips on the in- cab monitor.

Power, Performance & Efficiency
Power, Performance & Efficiency

Environmental concerns are growing worldwide, along with a need for cleaner engines. The Komatsu WA900-8 meets the latest EU Stage V emission regulations with Komatsu-designed, developed and manufactured engine and aftertreatment systems.

Two Diesel Particulate Filters, two Variable Geometry Turbos, a Heavy Duty and cooled exhaust gas recirculation system, new engine control modules, a Closed Crankcase Ventilation system - and no AdBlue® required, will allow WA900-8 customers to be competitive in tenders and to keep their Komatsu machine at work for many years.

Operator comfort
Operator comfort

The redesigned interior of the new and enlarged cabin offers better ergonomics to reduce fatigue, for a happy and more productive operator. To help stay focused and safe, sound insulation and a quieter engine keep noise levels low. 

A new fully adjustable seat, air-suspended, heated and ventilated, with an adjustable bolster and integrated standard EPC levers, makes life on the jobsite easier, as do the colour TFT monitor and a range of new tools and functions. A new fold-up trainer seat allows in-cab operator training. For less experienced operators, the Auto Digging system, the Semi-Auto Approach and the Semi-Auto Dump can assist to provide a consistent performance. 

The new right-hand side console is integrated in the seat. Switches and Bluetooth radio are easily accessible on the overhead console, and the new front panel is styled with a similar look and feel as other Komatsu machines.

Komatsu WA900-8 Walkaround

Not only does this new machine include an efficient engine and offer the highest rated load, but its new and super comfortable cabin is the largest ever on a Komatsu wheel loader

As standard, Komatsu offers up to 14,5 m³ buckets, that have a redesigned spill guard, increased radius and floor angle, and provide better penetration and higher fill factors to boost productivity and income. Their ultra-strong teeth and enlarged sweeper wings increase up time and reduce tire damage to also reduce maintenance costs.


For increased safety and operating confidence, KomVision, a visual aid designed by Komatsu to help avoid contacts or collisions due to blind spots, reduces risks of machine damage and injury. On the WA900-8, five network cameras create a bird’s-eye view of the immediate surroundings on a dedicated monitor. An extra rear-view camera sends a colour image with a distance indicator line on the cabin monitor. Catwalks and handrails on the counterweight provide an additional standard safe exit and easier maintenance. In option, Komatsu proposes an hydraulically operated 45° ladder to the cabin.

For easy servicing, even high up, technicians can attach lanyards to safe anchored tie-off points well-placed around the WA900-8. Standard safety lockout switches at the rear of the machine can be quickly reached from ground level, in an emergency or a critical situation. Engine maintenance points are grouped, and various ladders, stairs and handrails provide safe access to all filters. The optional service centre enables the wireless download of Komtrax Plus data, along with faster and easier oil servicing and sampling.
