Abstract

PURPOSE: To provide directional control of a self-traveling agricultural machine with less hunting by detecting the working speed and braking effect by detectors and controlling the braking time.
CONSTITUTION: When a right side sensor 47 detects the fact that an agricultural machine body does not travel along rows of plants, a solenoid control valve 41 is switched by an output generator 50 to thereby feed hydraulic oil to left side hydraulic oil to left side hydraulic cylinder 35 to thus disengage a clutch. On the other hand, left side brake 22 is thus engaged via a connecting rod 28 to allow the body to start turning to the left. Revolution sensors 31a, 31b detect the number of revolutions of the left and right wheels 5 to operate the generator 50 for the set time of a timer 51 due to the amplitude of the compared value therebetween. Accordingly, the cource turning angle by the brake does not largely vary according to the working speed and braking effect so as to provide directional control with less hunting.
