速操作構造。 The transmission system for the freely steerable front wheels 1a and 1b includes a front wheel that switches between a standard drive state in which power is transmitted at a drive speed approximately equal to the rear wheel drive speed, and an increased speed drive state in which power is transmitted at a drive speed greater than the rear wheel drive speed. Transmission device 18
and a work in which the steering handle 28 and the front wheel transmission 18 are linked so that the front wheel transmission 18 is operated to the speed-increasing drive side by a steering operation of a set angle or more from a straight-ahead state. A front wheel speed change operation structure of a vehicle, wherein the control handle 2
8 and the front wheel transmission 18 between the linked state and the linked disengaged state, when the switching lever 13 is operated to the linked side, the speed change lever 14 for driving is forcibly switched to the low speed side in conjunction with this, Further, the front wheel shift operation structure for a work vehicle is configured such that when the shift lever 14 is operated to the high speed side, the switching lever 13 is forcibly switched to the disengagement side in conjunction with this operation.
