A motor grader is provided with an engine, front and rear travel wheels, a transmission, a work implement, a control unit, and a vehicle speed adjusting knob. The transmission has hydraulic clutches for switching between forward and reverse travel and for switching between speed stages. The transmission 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. The work implement includes a blade for grading. During travel at a forward first speed, the control unit causes one of the hydraulic clutches of the transmission to operate as a braking clutch such that the motor grader travels 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.
