A motor grader is configured so that, when working while traveling at a very low speed, the motor grader can perform the work at an appropriate vehicle speed depending on situations. This motor grader is provided with: an engine (8); front and rear travel wheels (5, 6); a transmission (10) 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 (8), and transmits the power to either the front travel wheels and/or the rear travel wheels; a work machine (4) which includes a grading blade (32); a very low speed travel-controlling means; and a vehicle speed-adjusting knob (21). 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 clutch for braking, causing the motor grader to travel at a very low speed. The vehicle speed-adjusting knob (21) is a member for setting the vehicle speed during very low speed travel to an arbitrary speed.
