GD655-7 Motor Graders

Komatsu’s GD655-7 grader includes technology innovations so it’s easier and safer to use, as well as more productive. With a Komatsu SAA6D107E-3 Tier 4 Final engine, rated at 163-165 kW, operating weight is 19.3 tonnes. Technology innovations include updates to the transmission and control improvements. Plus, it’s factory-fitted for “plug-and-play” use of a 3D machine control system from leading third-party suppliers. 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 New Zealand-wide service and support network.
