Equipment Overview
The Komatsu GD555 is a motor grader built for road construction, maintenance and quarry work, part of Komatsu’s grader range alongside the larger GD655. It runs a 3.71 m (12 ft) moldboard as standard, weighs around 18,120 kg typically equipped, and produces up to 144 kW (193 hp), suited to council road work, civil earthworks and haul road maintenance on quarry and mine sites.
Power comes from a Komatsu SAA6D107E-1 engine, meeting Tier 3/Stage 3A emissions standards. Komatsu’s dual-mode transmission lets the operator switch between full power shift and a lock-up torque converter, giving smooth low-speed control for fine grading or stronger tractive effort for heavier work. A hydraulic reversing cooling fan and ground-level refuelling keep servicing straightforward, and the hexagonal cab is built for a clear view of the blade.
