Abstract
PURPOSE:To improve the operational performance, etc., of the tractor in the caption by changing over its running speed according to the operation of a pedal for adjusting the speed of a prime mover, in the case that the running speed is controlled according to the selection of both work and turn speeds. CONSTITUTION:A power transmission mechanism within a front power transmission case 8, to which power is transmitted from a prime mover 17, transmits power to right and left rear wheels 9 via a speed change transmission mechanism 2 within a rear power transmission case 11. Furthermore when a speed indicator 1 is operated to select a work speed, the speed change transmission mechanism 2 is set to the selected work speed via a control part 3 and a solenoid valve 10. In this case, when a censor 4 detects that a pedal 4 for adjusting the speed of the prime mover 17 has been operated, the speed change transmission mechanism 2 is changed over to a turn speed via the control part 3 and the solenoid valve 10. Also when the censor 4 detects that the operation of the pedal 4 has been suspended following the completion of turning, the speed change transmission mechanism 2 is changed over to the initial work speed via the control part 3 and the solenoid valve 10.
