Komatsu GD555 Motor Grader
Motor Graders 2011
The GD555 gets exceptional power and efficiency from the turbocharged and air to air aftercooled engine. Output is 119kW 160 HP SAA6D102E (variable horsepower in higher gears) providing excellent tractive effort with good fuel efficiency.
Electronic Overspeed Protection helps prevent engine and transmission damage from premature downshifting and grade-induced overspeeding.
Electronic Transmission Control produces smooth shifting, which enables the operator to maintain a uniform grading surface if shifting is required. Smooth shifts also extend the life of the transmission by placing less stress on transmission clutches. A single lever controls direction, speed and parking brake.
