Large Dumping Clearance
The WA900-3 was
designed with ample
dumping clearance for
dump truck matching.
High Breakout Force
Komatsu wheel loaders have high-tensile steel Z-bar loader
linkages for maximum rigidity and maximum breakout force.
Sealed loader linkage pins extend greasing intervals.

High Performance SAA12V140E-3 Engine
Electronic Heavy Duty Common Rail fuel injection system
provides optimum combustion of fuel.
This system also provides fast throttle response to match the
machine’s powerful tractive effort and fast hydraulic response.
Net: 638 kW
856 HP
Low Emission Engine
This engine is EPA Tier 2 emission certified without
sacrificing power or machine productivity.
Low Fuel Consumption
Low fuel consumption is achieved because of the
low-noise, high-torque engine and the large-capacity torque
converter with maximum efficiency in the low-speed range.
Durable Bucket
Komatsu buckets are manufactured using high-tensile
strength steel with replaceable welded wear plates for
extended bucket life. Additional strength has been added to
the bucket bottom corners, side edges and spill guard ends
for increased durability.

Dual-Mode Active Working System
The machine can be equipped with two mode active working
system. This system provides the most efficient hydraulic flow
for your operation.
The active working
switch has two
modes: powerful
loading or normal
loading.
●
Powerful loading mode:
Hydraulic flow towards the work equipment can be
increased and reduced as and when required.
●
Normal loading mode:
All hydraulic flow is transferred directly to the work
equipment.
Digging/Loading
Reduces hydraulic flow from switch pump when necessary.
Traction is increased, as the hydraulic pressure load for digging/shoveling is reduced.
Easy for heavy digging.
