Kind Code:
B2
Abstract:
This working vehicle 1 is provided with: a traveling machine body 2 having an engine 5 mounted thereon; left and right traveling sections 4 for supporting the traveling machine body 2; a steering operation device 14 for changing the direction of movement of the traveling machine body 2; and left and right primary transmission/interruption members 48 for transmitting and interrupting power to the left and right traveling sections 4, and the working vehicle 1 is configured such that a primary transmission/interruption member 48 is operated according to the steering operation of the steering operation device 14, thereby interrupting power to a traveling section 4 on the inner side with respect to turning. The working vehicle 1 comprises, separately from the left and right primary transmission/interruption members 48, left and right secondary transmission/interruption members 111 and left and right speed reduction mechanisms 131. As the primary transmission/interruption member 48 is operated to interrupt power to the traveling section 4 on the inner side with respect to turning, a secondary transmission/interruption member 111 is operated and connected to the traveling section 4 on the inner side with respect to turning, and as a result, power for the traveling section 4 on the inner side with respect to turning is transmitted either through a speed reduction mechanism 131 or through both the secondary transmission/interruption member 111 and the speed reduction mechanism 131 to drive the traveling section 4 on the inner side with respect to turning, at a lower speed than the traveling section 4 on the outer side with respect to turning.
