If your operators want lots of power but with complete control in a small package, the WA200-7 is a machine they’ll love. Hydrostatic drive gives the WA200-7 the advantage of having a fully automatic drive system without the weight and wear of a torque converter and geared transmission. The result is quick response, lots of power to dig and climb, the ability to control traction level and dynamic braking which saves wear on the wet multi-disc brakes.

WA200-7 Walkaround  >


Komatsu Diesel Oxidation Catalyst (KDOC)

The new Komatsu Diesel Oxidation Catalyst (KDOC) has an integrated design that does not interfere with daily operation. This smart and simplified system removes soot using 100% "passive regeneration" without the need for a Diesel Particulate Filter. The KDOC's simple design does not have a scheduled service interval and no required maintenance. For owners, this means lower owning and operating costs due to less complexity and truly seamless operation for the operator.

Right-side Control Panel

The operator can select the speed range, variable speed control, and tractive effort on the right side control panel. This is also where the directional selector switch (activates the FNR switch on the multi-function mono lever) is located. The control panel allows the operator to control the auto reverse cooling fan, 2-stage low idle function and select between two attachments, when equipped. Finally, the work equipment lock switch can be found here.

Multi-Function Mono Lever

The servo-assisted multi-function mono lever, with control for optional 3rd spool, is standard. It includes a forwardneutral- reverse switch for quick and easy travel. Third spool attachments can be set to continual or proportional control allowing the operator to control the boom, bucket and attachment all with a single lever.

Variable Flow Turbocharger (VFT)

The variable flow turbocharger features simple and reliable technology that varies the intake airflow. This provides optimum air flow under all speed and load conditions producing cleaner exhaust gas without sacrificing power or performance.

Variable Speed Control

Creep mode limits the travel speed while still allowing for full hydraulic flow.

Electronically Controlled Suspension System (ECSS)

The Electronically Controlled Suspension System (ECSS) or ride control system uses an accumulator which absorbs some of the shock in the boom arm, giving the operator a much smoother ride. This reduces operator fatigue and reduces material spillage during load and carry operations. ECSS is speed sensitive, meaning that the boom won’t move during stationary digging. ECSS is standard on the WA200-7.
