Features :- Komatsu Motor Graders
- GD655-3
Electronic monitor with self-diagnostic function.
Tinted glass reduces glare, adding to operator comfort.
A simple blade suspension system allows good forward visibility.
Stable work equipment speeds are unaffected by engine speed.
Low front nose providing good visibility.
A wide working range is accomplished through unsurpassed blade geometry.
Bronze alloy guides on blade and circle provide long service life.
The lock-up torque converter provides smooth power for grading and speed for roading or snow removal.
KOMTRAX equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.
Excellent visibility
Front and rear glass is angled to prevent dust build-up.
Rear window has electric defroster and a wiper as standard equipment.
Komatsu SAA6D114E-3 turbocharged and aftercooled diesel provides 134 kW 180 HP to 149 kW 200 HP for demanding applications. This engine is EPA Tier 3 and EU stage 3A emissions certified, without sacrificing power or machine production.
Access to all necessary engine maintenance items is easy with wide hinged compartment doors.
Brakes are maintenance-free hydraulically operated wet type multiple-disc.
Wheel spin is reduced with the manual lock/unlock differential.
