High Productivity and Low Fuel Consumption

A powerful SAA6D107E-1 turbocharged air-to-air aftercooled diesel engine provides a net output of 103 kW / 138 HP for the WA250PZ-6. This engine is EPA Tier 3 emissions certified, without sacrificing power or machine productivity. The high-torque engine and Hydrostatic Transmission (HST) with maximum efficiency in the low-speed range provide low fuel consumption.

Electronically-Controlled HST

The electronically-controlled HST consists of a 1-pump, 2-motor system. This system allows for high-efficiency and high tractive effort. The HST provides quick travel response and aggressive drive into the pile. The variable displacement system automatically adjusts to the tractive effort demand to provide maximum power and efficiency

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.
