KOMATSU GD655-3E0 MOTOR GRADERS

Technical Description

The 2008 Komatsu GD655-3E0 is a heavy-duty motor grader powered by a SAA6D114E-3 engine with 180 net horsepower at 1900 rpm, delivering 200 hp in higher gears with peak torque of 719 lb-ft. This full power shift transmission features eight forward and reverse speeds, enabling precise ground-level control for finish grading and road maintenance operations. The machine operates at approximately 35,000-40,840 lbs, providing substantial traction and stability across varied terrain. Its 12-foot moldboard with 24-inch blade height facilitates efficient material movement and grading precision. The GD655-3E0 incorporates a closed-center, load-sensing hydraulic system with variable displacement piston pump delivering 51 gallons per minute at 3000 psi, enabling simultaneous operation of multiple circuits independent of engine speed. The cab features an ergonomic air suspension seat designed to reduce operator fatigue during extended working days, combined with enhanced visibility through a low-profile hexangular design. EPA Tier 3 and EU Stage 3A certified, the engine balances power with fuel efficiency through common rail fuel injection technology. Standard equipment includes a rearview monitor system with dedicated display for improved safety and situational awareness on job sites. The machine's responsive hydraulic controls and anti-stall technology provide steady efficiency for both fine precision work and heavy-duty pushing applications, making it suitable for diverse grading, road maintenance, and site preparation tasks.
