The WD900-3A comes with a powerful, fuel-efficient SA12V140 engine and down-switch on the blade control lever for the most efficient dozing operations. A stick-steer control system makes for low-effort steering while a high-capacity air conditioner is installed in the roomy, quiet cab to prevent operator fatigue. Key components are designed and manufactured by Komatsu to work together in an integrated package.

Automatic transmission
The automatic shift control provides maximum control with minimum effort. The transmission hold switch allows the operator to select automatic and manual gearshift. The unique combination of transmission hold and kick-down switches, in the hydraulic blade controller, provides an optimum control in every condition.

Kick-down Switch
The kick-down switch is conveniently located in the blade controller. A simple movement with the thumb activates this valuable feature.
