Purchase options
Request a quoteThe agile WD600-6 comes with a low-noise, high-torque engine that greatly reduces fuel consumption while a large-capacity torque converter provides for maximum efficiency in the low-speed range. The cab area is the largest in its class and provides the operator with exceptional front visibility. Key components are designed and manufactured by Komatsu to work together in an integrated package.
Resources
Features and benefits
High productivity & low fuel consumption
The WD600-6 Wheel Dozer features a high performance SAA6D170E-5 engine, which is EPA Tier 3 and EU Stage 3A emissions certified, without sacrificing power or machine productivity. The Komatsu designed lock-up torque converter provides increased production efficiency, reduced cycle times and optimum fuel savings in hill-climb operations.
Excellent operator environment
The WD6006-6 has a wide pillar-less flat glass provides excellent front visibility. The wiper arm covers a large area to provide great visibility even on rainy days. The cab area is the largest in its class providing maximum space for the operator.
Reliability
Komatsu manufactures the engine, torque converter, transmission, hydraulic units, electric parts, on this wheel dozer. Komatsu dozers are manufactured with an integrated production system under a strict quality control system.
