Komatsu launches GD655-7 motor grader with more spacious cab

Komatsu America has launched its GD655-7 motor grader which it says comes with a spacious cab, providing more room for operators working long days.

Bruce Boebel, senior product manager, Komatsu America, says: “Operators will appreciate the new low-effort equipment and steering levers, new transmission controls and articulation stop-at-centre feature. Collectively, they significantly reduce operator fatigue.”

The GD655-7 is equipped with an EPA Tier 4 Final certified emissions regulations-compliant engine, which will be sold concurrently with the current GD655-6 model to offer customers additional choices to meet their needs.

Standard features of the GD655-7 include:

New Cab Enhancements

  • 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

Under The Hood

  • 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

Power Train Performance

  • 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

Other Standard Value Features Included

  • 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

Serviceability / Komatsu CARE

  • 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.
