Updated Komatsu Motor Grader

New Features in the GD655-7 Deliver Better Ergonomics to Lessen Operator Fatigue and Boost Productivity

If asked to describe the ease of use with typical motor graders, most operators would steer clear of calling it a low-effort task. However, today’s updated models provide a host of features designed to significantly reduce operator fatigue and increase productivity.

“The GD655-7 provides an all new, ultra-ergonomic working environment, and the new spacious cab allows more room during long working days,” said Komatsu Senior Product Manager Bruce Boebel. “Operators will appreciate the low-effort operation and steering levers, new transmission controls as well as the articulation stop-at-center function that simplifies use.”

New performance features include a transmission shift lever with finger-operated forward-neutral-reverse switch that reduces required hand movement. That’s in addition to the already standard Komatsu power-shift transmission that was designed and specifically built for Komatsu graders and delivers on-the-go, full-power shifting.

Greater Speed, Less Fuel

The GD655-7 offers inching capability and automatic shifting in higher ranges. An industry exclusive, dual-mode transmission with eight forward and four reverse speeds, allows higher travel speeds and reduces fuel consumption of a direct drive. It also delivers increased tractive effort and the control of a torque converter.

“It is grade-control ready, with no aftermarket valve required,” Boebel noted. “Additionally, the GD655-7 has two standard, five-section hydraulic control valves that enable the addition of attachments and are strategically located to improve forward visibility.”

New cab enhancements include a slightly smaller but “right-sized” steering wheel that provides more visibility and room and is convenient for long “blade-up and roading” trips. A steering lever allows operators to keep hands on the low-effort equipment levers and make small steering adjustments while at work, without the need to turn the steering wheel. Highly adjustable arm rests and consoles have power raise and lower functions and mechanical fore/aft adjustments to precisely fit user preferences.

“Operators can select Power or Economy mode to match conditions and optimize fuel savings,” said Boebel. “This is a highly productive machine, and a solid choice for anyone who uses a motor grader for construction, road building, snow clearing or other applications.”

Boebel points out that the new GD655-7 is among the leaders in the 20-ton range, and it will be sold concurrently with the Dash-6 model to offer customers an additional choice to meet their needs.
