MOTOR GRADER

摘要

A motor grader is provided with an engine, front and rear travel wheels, a transmission which has hydraulic clutches for switching between forward and reverse travel and for switching between speed stages, changes the speed of power from the engine, and transmits the power to either the front travel wheels and/or to the rear travel wheels; a work implement which includes a blade for grading; a very low-speed travel controlling means; and a vehicle speed adjusting knob. During travel at a forward first speed, the very low-speed travel controlling means causes one of the hydraulic clutches of the transmission to operate as a braking clutch, causing the motor grader to travel at a very low speed. The vehicle speed adjusting knob is a member for setting the vehicle speed during very low-speed travel to an arbitrary speed.
