Choice of automatic or direct drive tranny

Komatsu’s Laterra grader line offers three models, the GD555A-3, the GD655A-3 and the GD675A-3 ranging in operating weight from 30,525 to 34,390 pounds and in horsepower from 140 to 200. Variable horsepower is available for all models. The Laterra line features a dual-mode transmission that allows the operator to move from torque-converter to direct-drive mode by the flip of a switch. The direct-drive mode offers you the chance to use the same transmission used on most motor graders. The torque-converter mode gives you slow speed control and power without stalling out under load.
