Abstract
In a motor grader, controls for running the vehicle at a constant speed are provided when a work for improving a land surface with a blade is started by running a working vehicle at a low speed from the low idling start. With this operation, it is possible to perform the work for improving a land surface by maintaining an actual revolution speed of the engineat a value obtained by subtracting a prespecified revolution speed from the revolution speed for low idling to run the working vehicle at a low speed. With this feature, it is possible to continue the work at a constant speed and also to prevent occurrence of engine stop during the work at a low speed, when a higher duty of the engine is required and the actual revolution speed drops like in the case where an ascending slope of the land to be improved becomes large or where the cutting rate temporally increases due to local irregularities of the land surface during the land surface improvement work.
