Abstract

PURPOSE: To conduct smooth directional control of an agricultural vehicle by a system wherein a hydraulic control means is provided on a hydraulic circuit for driving a hydraulic cylinder and the hydraulic means is controlled by detected signals.
CONSTITUTION: When a leftward drive signal runs in a solenoid 48a, the parallel circuit opens and high pressure oil discharged from a pump 41 passes through an electromagnetic valve 46. Then, the pressure oil enters a hydraulic cylinder 14a through an electromagnetic valve 48 and makes a piston rod 22a project against a return spring 50. Therefore, a clutch brake mechanism operates. If a brake control signal is output from a terminal C and passes through a solenoid 46a when the clutch is broken, the electromagnetic valve 46 is shut and the oil runs into the hydraulic cylinder 14a through an orifice 47. At this time the oil pressure is reduced by the orifice 47 and its flow rate is decreased and as a result the hydraulic cylinder 14a is driven slowly at a given low pressure. Therefore, the brake is actuated smoothly and directional control is carried out.
