Abstract
PURPOSE: To facilitate operation and prevent wrong operation of an agricultural macnine such as crawler only by swinging one operating lever forward, backward, left and right to permit speed change and steering.
CONSTITUTION: Forward and backward swing of an operating lever 31 operates a transmission 47 to change simultaneously speed of left and right travelling devices 59, 59 in a gear box 53. Further, left and right swing of the operating lever 31 operates a side clutch device 65 to turn on and off individually the power of the left and right travelling devices 59, 59 respectively. Namely, the left swing of the operating lever 31 raises the right portion of an operating plate 35, pushes up an operating plate 27 of a limit switch 19, presses a sensor and passes current from a battery 67 to a coil 75 of a solenoid valve 71 to shift the valve 71 to position (a) so that a hydraulic cylinder 81 is operated. Hence, a swing body 103 swings in the direction F to operate a clutch 109 for applying brake to a left axle 141. Also, power rotates an axle 143 through a gear 115 of a right clutch 111 so that left turning can be carried out.
