連動連結してある作業車の前輪変速操作構造。 A front wheel transmission device that switches the transmission system to the front wheels 1, which can be freely steered, between a standard drive state in which transmission is performed at a drive speed approximately equal to the rear wheel drive speed, and an increased speed drive state in which transmission is transmitted at a drive speed greater than the rear wheel drive speed. 10, and the operating handle 12 and the front wheel transmission 10 are linked so that the front wheel transmission 10 is operated to the speed-increasing drive side by a steering operation of a set angle or more from a straight-ahead state. In the front wheel transmission operation structure, when the switching lever 14 for switching the control handle 12 and the front wheel transmission 10 between a linked state and a linked release state is operated to the linked side,
In conjunction with this, the speed change lever 13 for traveling is operated to switch from the high speed side to the neutral stop position N, and when the speed change lever 13 is operated to the high speed side, the change lever 14 is moved from the link side to the link release side in conjunction with this. A front wheel speed change operation structure for a work vehicle in which a switching lever 14 and a speed change lever 13 are interlocked and connected so that they can be operated.
