Claim 1:
2. A working vehicle comprising:
a traveling device including a front wheel and a rear wheel;
a steering handle;
a vehicle body to travel with either manual steering by the steering handle or automatic steering of the steering handle along a scheduled traveling line set based on a traveling reference line;
a position detector to detect where the vehicle body is positioned;
a reference line setter switch to set a position of the vehicle body detected by the position detector to a start position of the traveling reference line and set another position of the vehicle body detected by the position detector to an end position of the traveling reference line;
a steering switch to switch the automatic steering along the scheduled traveling line between to be started and to be terminated, the scheduled traveling line being not associated with a length of the traveling reference line;
a double-speed transmission to increase a rotating speed of the front wheel to be higher than a rotating speed of the rear wheel under a predetermined operation condition where a steering angle of the steering handle is a predetermined angle or more; and
a controller to:
(i) when the steering angle of the steering handle is the predetermined angle or more while the automatic steering is performed, terminate the automatic steering and cause the double-speed transmission to increase the rotating speed of the front wheel to be higher than the rotating speed of the rear wheel after termination of the automatic steering; and
(ii) while the double-speed transmission is in operation while the automatic steering is not performed, not start the automatic steering even when the steering switch switches the automatic steering to be started.
