せてある農用トラクターの走行用操作構造。 A first four-wheel drive state in which the average circumferential speed of the pair of left and right steerable front wheels 1a, 1b and the average circumferential speed of the pair of left and right rear wheels 2a, 2b are the same or almost the same, the front wheels 1a, 1 for each of a two-wheel drive state in which power transmission to the pair of front wheels 1a and 1b is cut off, and a second four-wheel drive state in which the average circumferential speed of the pair of front wheels 1a and 1b is greater than the average circumferential speed of the pair of rear wheels 2a and 2b.
A transmission 15 that can switch between the two-wheel drive states using two shifters 26 is installed in the transmission case 14, and when the steering angle of the front wheels 1a, 1b is less than a set value, the transmission 15 is in the first four-wheel drive state, and the front wheel 1a
, 1b are steered beyond the set value so that the transmission 15 is automatically switched to the second four-wheel drive state. The interlocking member 11 is provided with an interlocking mechanism 43 that interlocks the shifter 26, and the interlocking tool 31 constituting the interlocking mechanism 43 is located closer to the shifter 26 than the interlocking tool 31 and penetrates into the mission case 14. The first rotation interlocking tool is configured to rotate integrally with the first rotation interlocking tool 30 provided therein, and to engage and disengage from the second rotation interlocking tool 34 located closer to the interlocking member 11 than the interlocking tool 31. 30 is integrally rotatably and slidably attached to a portion located outside the mission case 14, and the interlocking mechanism 43 is switched between an interlocking state and a non-interlocking state by sliding and rotating operations of the interlocking tool 31. , and an operating mechanism 53 is provided for switching the transmission mechanism 15 between the first four-wheel drive state and the two-wheel drive state when the interlocking mechanism 43 is not interlocked, and the first rotation interlocking tool 30 of the interlocking tool 31 is provided. This operating structure for running an agricultural tractor is provided with a detent mechanism 65 attached to the interlocking tool 31 for positioning in a sliding direction relative to A spring 33 attached to the interlocking tool 31 and urging the shifter 26 to a position where the transmission 15 is in the first four-wheel drive state is locked to the loop portion 64a of the split pin 64a. Tractor running operation structure.
