The Komatsu GD655-7 Grader provides operators with an all new, ergonomic working environment and the new spacious cab allows more room for operators working long days. Operators will appreciate the new low-effort equipment and steering levers, new transmission controls and articulation stop-at-center feature. Collectively, they significantly reduce operator fatigue.

Features

Slightly smaller but “right sized” steering wheel provides more visibility and operator room in the cab, convenient for those long, “blade-up and roading” trips
New steering lever allows the operator to keep hands on the low-effort, work equipment levers and make small steering adjustments, while operating without needing to turn the steering wheel
New multi-position adjustable arm rests and LH/RH consoles have power raise/lower and mechanical fore/aft adjustments to precisely adjust to operator preferences.
New, high-capacity, air-suspension seat softens in-cab machine vibrations for operator
New stop-at-center articulation feature simplifies operation
New operator presence monitoring system alerts the operator if they leave the seat and controls are not locked out properly

A powerful 218 HP (163 kW), EPA Tier 4 Final certified, SAA6D107E-3 engine
2-mode, 3-stage Variable Horsepower Control (VHPC) allows the selection of the appropriate mode, economy or power, to match operating parameters to application requirements for optimal fuel savings
Komatsu Diesel Particulate Filter (KDPF) and other after treatment components are designed in conjunction with the engine for efficiency and long life
More than 98 percent of KDPF regeneration is performed passively, with no action required of the operator and no interference with machine operation

New transmission shift lever with finger-operated forward-neutral-reverse switch simplifies operation and dramatically reduces required hand movement
Komatsu power shift transmission designed and built specifically for Komatsu graders provides on-the-go, full power shifting, as well as inching capability and automatic shifting in the higher ranges
Industry exclusive, dual-mode transmission (8 forward, 4 reverse) allows operators to benefit from the high travel speeds and reduced fuel consumption of a direct drive, as well as the increased tractive effort and control of a torque converter
An inching pedal gives the operator precise control of machine movement
Full locking differential provides the traction required in the most severe operating conditions

Grade control, TOPCON 3DMC plug-and-play ready, with no aftermarket valve required
Two, five-section hydraulic control valves are standard enabling the addition of attachments and is strategically located to improve forward visibility
Closed-center Load Sensing (CLSS) hydraulic system, with variable displacement pump, supplies flow and pressure only when required, resulting in less heat and lower fuel consumption
Blade lift accumulators absorb shocks when the moldboard hits immovable objects
Circle slip clutch, for accidental contact with hidden objects with the moldboard
Greaseless circle wear plates for long life
Independent blade lift float
AM/FM radio with auxiliary input jack and two 12-volt ports
Seven-inch, full color, high resolution monitor with Ecology Guidance
Separate, full color, rearview monitoring system
Pioneering KOMTRAX telematics system and monitor, providing machine metrics, including KDPF status and DEF-level data, fuel consumption, plus performance information collected and sorted by operator ID
Komatsu Auto Idle Shutdown to reduce idle time and save fuel

Reversible, variable speed hydraulic fan to blow out dust accumulation in the cooler
Completely sealed and adjustment-free hydraulically actuated, wet, disc brakes
Ground level access to fuel and DEF fill
Easily accessible engine and hydraulic oil, and coolant drains
All Komatsu GD655-7 units come with Komatsu CARE. Komatsu CARE provides scheduled factory maintenance for the first 2,000 hours or three years including a 50-point inspection at each service, and two complimentary KDPF exchanges in the first five years.
