ROLLING MEADOWS, IL - Komatsu America Corp. introduces the new WD600-6 wheel dozer equipped with a Tier 3 compliant engine.  The 108,280 pound WD600-6 is designed to work with either a straight blade or U blade in many applications.  It offers improved productivity, lower fuel consumption and increased reliability.

The WD600-6 is powered by a Komatsu Tier 3, SAA6D170E-5 six-cylinder engine, which produces 502 HP at 1,800 RPM, a significant increase in horsepower over the previous model.  Komatsu's Tier 3 engine is equipped with new technologies including an electronic control system to optimize vehicle performance; a heavy-duty High Pressure Common Rail Fuel Injection System; a new combustion system for reduced noise and fuel consumption; a cooled Exhaust Gas Recirculation system and an air-to-air charge air-cooling system.  The WD600-6's engine comes standard with dual-mode engine power: an Economy mode for maximum fuel efficiency, and a Power mode for maximum productivity.

Designed for Operator Comfort
The WD600-6's large operator's cab has been ergonomically designed to provide the operator with more room and easy access to all switches and levers to minimize operator fatigue and improve productivity.  The cab features AJSS (Automatic Joy Stick Steering) which allows for easier and more accurate directional control.  An EPC (Electronic Pilot Control) mono-lever is provided for efficient control of the work equipment.  The operator's cab comes with large fully-adjustable left and right armrests, increased fore and aft travel of the air ride seat and an automatic heater/defroster/AC. 

Komatsu developed a Level-2 ROPS/FOPS integral cabin with rubber and silicone viscous damping mounts to reduce cab vibration and noise levels.  The large-size flat glass windows provide maximum visibility. 

Power and Productivity
For dozing applications, a new, large capacity torque converter with lock-up transmission provides increased productivity, faster cycle times and improved fuel consumption.  With a 3-element, single stage, double-phase torque converter and a full-powershift, planetary type transmission, travel speeds have increased over the previous model, with a forward top-speed of 23.4 mph and a reverse top-speed of 22.4 mph.
