の前輪変速操作構造。 A standard drive state in which the transmission system to the steerable front wheels 1 is transmitted at a drive speed approximately equal to the rear wheel drive speed;
It is equipped with a front wheel transmission 10 that switches to an increased speed driving state in which transmission is performed at a drive speed higher than the rear wheel drive speed, and includes a control handle 12 and the front wheel transmission 10.
The front wheel transmission operation structure of a work vehicle is configured such that the front wheel transmission device 10 is operated to the speed-increasing drive side by a steering operation of a predetermined angle or more from a straight-ahead state, in which the steering handle 12 When the switching lever 14 that switches the front wheel transmission 10 between the linked state and the released state is operated to the linked position, the operation of the speed change lever 13 for traveling toward the high speed side is mechanically checked and prevented, and the speed change lever 13 A front wheel shift operation structure for a working vehicle is configured to mechanically check and prevent the switching lever 14 from being operated to the linking side when the switching lever 14 is operated to the high speed side.
