High Productivity and Low Fuel Consumption

An electronic heavy duty common rail fuel injection system provides optimum combustion of fuel. The system also provides fast throttle response to match the machine's powerful tractive effort and fast hydraulic response.

Large-Capacity Torque Converter

Newly designed drive train has a large-capacity torque converter for optimal efficiency. The WA430-6 has plenty of acceleration and it can achieve high travel speeds, even on grades. This significantly assists productivity and also delivers great value for load-and-carry operations.

Easy Maintenance

The operator can open and close each gull-wing type engine side door easily with the assistance of a gas spring to perform daily service checks from the ground.
