Features :- Komatsu Motor Graders
- GD555-3
The advanced monitoring system delivers self-diagnostics and can provide historical diagnostic information.
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.
Operator comfort - is a priority with low noise environment, excellent visibility with slim beams and post and well positioned air conditioner vents.
Excellent visibility to the rear. Front and rear glass is angled to prevent dust build up.
Komatsu SAA6D102E-2 turbocharged and aftercooled diesel provides 140 HP / 104 kW to 160 HP / 119 kW for demanding applications.
Access to all necessary engine maintenance items is easy with wide hinged compartment doors.
Brakes are hydraulically operated wet type multiple-disc and maintenance free. No air system.
The lock-up torque converter provides smooth power for grading and speed for roading or snow removal.
Wheel spin is reduced with the manual lock/unlock differential.
