GD655-6 Motor Graders

Now with a low-emission Tier 4 Final-compliant engine, Komatsu’s GD655-6 grader includes variable horsepower (134-165 kW), as well as outstanding visibility to the blade and work areas and our unique dual mode transmission system that combines the ability to switch between full powershift and lockup automatic torque converter. As with all our graders, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our NZ-wide service and support network.

High Performance Komatsu Engine

The GD655-6 features a new SAA6D107E-3 Tier 4 Final compliant engine and when coupled to Komatsu's Dual Mode Transmission, operators benefit from maximum control while reducing fuel consumption by up to 5% in Power Mode and 15% in Economy Mode.

Komatsu Diesel Particulate Filter and Selective Catalytic Reduction System

The KDPF and SCR reduces particulate matter and NOx while providing automatic regeneration that does not interfere with daily operation.

Versatile Moldboard Geometry

Komatsu graders feature a versatile moldboard geometry. Save time and money when pulling ditches by throwing the windrow to the right, not the roadway - without narrowing the road bed. It's made possible by Komatsu's extraordinary reach and aggressive blade angle.
