Komatsu Wheel Loaders WD600-6
WD600-6 Wheel Dozer
High productivity is the story of the WD600-6 wheeled dozer. The operator has two engine power modes, load sensing hydraulics and a modulated clutch system to harness the 527 horsepower to maximize production when moving mass quantities of soil, coal, chips, slurry or whatever gets in the way.
