Gear-Drive Tandem for Largest Model

摘要

Model 785, largest in the LeeBoy motor-grader lineup, uses a 6F/3R power-shift, torque-converter transmission and a gear-drive tandem (no chains) that features a differential lock and multi-disc braking system. The smaller 685B and 635B are hydrostatically driven, with the 685B incorporating a heavy-duty two-speed gearbox and the 635B a heavy-duty two-speed hydraulic motor.
