PURPOSE:To facilitate a regular rotation control of driven bodies by controlling a pump and an engine according to a predetermined program on the basis of an established signal and a rotational signal of driven bodies through use of a microcomputer. CONSTITUTION:An established signal from an operation part 3 and signals from a rotational frequency sensor 13 for driven bodies 2 such as a mixer drum and the like are inputted to a microcomputer 12, which controls a pump 6 and an engine accelerator by means of driving devices 9 and 14 on the basis of said signals. Since the microcomputer is used for controlling rotational speed of driven bodies, a drive can be made by a regular rotational speed regardless of whether a vehicle is traveling or stopping. Further, useless engine racing and waste of fuel are excluded. |
