PURPOSE:To prevent the slip of tire when vehicular speeds are improper by a method in which a set value for starting control on a working machine is automatically corrected according to vehicular speed values detected by a sensor during the penetrating and excavating work period. CONSTITUTION:An angle sensor 2 for a bucket 1, an angle sensor 4 for a boom 3, a sensor to detect the oil pressure of a boom cylinder 5, a sensor to detect oil pressure of a bucket cylinder 7, and a sensor 9 for vehicular speed are provided. In a microcomputer in which detected values by each sensor are inputted, the driving of oil-pressure circuit is controlled on the basis of the horizontal and vertical components Rh and Rv of excavating resistance applying to the bucket 1 during excavation by using the detected values, and the set value is corrected according to vehicular speed V detected during the penetrating and traveling work period. The occurrence of slip of tire can thus be prevented, thereby lengthening the life of the tire.
