業車。 One shift member 1 is provided for a standard drive state in which transmission is performed at a drive speed substantially equal to the rear wheel drive speed, and an increased speed drive state in which transmission is performed at a drive speed greater than the rear wheel drive speed.
A four-wheel drive working vehicle is provided with a front wheel transmission 7 which can be selectively switched by a sliding operation 5 in the transmission system to the front wheels 1 which can be freely steered, and wherein the shift member 15 or this shift fork 1 for
9 toward the standard drive side, and an operating member 24 that contacts and pushes the shift fork 19 from the standard drive side to the speed-up drive side when the front wheels 1 are steered at a preset angle or more. A four-wheel drive type work vehicle which can be operated to switch between an active position A, which is applied, and a non-active position B, which is separated from a shift fork 19.
