Outdoor motor grader GD655-6

for construction

Overview
The GD655-6 motor grader by Komatsu delivers precise surface grading with operator-focused visibility and dual-mode transmission for adaptable performance.

• Exceptional operator visibility and job-site awareness
• Smooth power delivery with selectable fuel-efficiency modes
• High-flow CLSS hydraulics for responsive implement control
• Improved fuel efficiency up to 15% in E-Mode versus previous generation

Features and benefits

• Dual-mode powershift transmission with torque converter — Selectable P-Mode/E-Mode and anti-stall functionality for precise finish grading and heavy-push performance.
• Fuel-efficiency power modes — Eco mode for low-consumption fine work and power mode for high-demand tasks.
• Standard blade lift accumulators — Protects moldboard, drawbar and circle by absorbing impacts.
• Operator comfort — Air-suspension seat and low-profile hexagonal cab for reduced fatigue and enhanced visibility.
• CLSS closed-center load-sensing hydraulics — Multi-circuit capability provides constant implement speed and simultaneous operations independent of engine speed.
• Hydraulic reversing cooling fan — Variable operation according to engine load and temperature for efficiency.
• Telematics (Komtrax) — Remote service alerts, operating history and fuel usage data for fleet management.
