Equipment Overview
The Komatsu GD655 is a motor grader built for road construction, maintenance and quarry work, part of Komatsu’s grader range alongside the smaller GD555. It runs a 4.27 m (14 ft) moldboard as standard, weighs around 20.2 tonnes typically equipped, and produces up to 163 kW (218 hp), suited to council road work, civil earthworks and haul road maintenance on quarry and mine sites.
Power comes from a Komatsu SAA6D107E-3 engine, meeting Tier 4 Final emissions standards. Komatsu’s dual-mode transmission combines full power shift with a torque converter and lock-up clutch, automatically stepping in to prevent stalling under heavy load, while the hexagonal cab gives a clear view of the moldboard and front tyres.
