Abstract:
1. A working vehicle comprising: an engine; a main speed-changing device that changes the rotation power of the engine to any of a plurality of shift positions; an auxiliary speed-changing device that further shifts the shift position selected by the main speed-changing device to any of the plurality of shift positions; wheels that are transmitted the rotation power of the engine through the main and auxiliary speed-changing devices; a shift lever that switches the shift position of the auxiliary speed-changing device by manual operation; an accelerator pedal and/or a throttle lever for adjusting the rotation speed of the engine by manual operations; shift means that makes the shift lever switchable between an operation position P a shift control device that switches the shift position of the main speed-changing device by interlocking with a manual operation on the accelerator pedal and/or the throttle lever, disables shifting of the main speed-changing device to the shift range of the low speed side, and enables shifting to the shift range of the high speed side when the shift lever is switched to the operation position P
