操作構造。 In the transmission system to the steerable front wheels 1, 1, the rear wheels 2,
2, and a front wheel transmission 10 that switches between a standard drive state in which transmission is performed at a drive speed substantially equal to the drive speed of the rear wheels 2, and an increased speed drive state in which transmission is performed at a drive speed greater than the drive speed of the rear wheels 2, 2. Left and right side brake pedals 12a, 1 that brake 2 independently on the left and right sides
2a, the front wheel transmission device 10 is configured to switch from a standard drive state to an increased speed drive state in response to a depression operation of either one of the left and right side brake pedals 12a, 12b. Wire support arms 13a and 13b are connected from each other, and one wire support arm 13a connects and supports the inner wire 14a of the first release wire 14 and the outer wire 16b of the second release wire 16, and the other wire support arm 13b connects and supports the outer wire 14b of the first release wire 14 and the inner wire 16a of the second release wire 16, and connects the other end of each inner wire 14a, 16a of the first and second release wires 14, 16 to the In conjunction with the operating lever 10a of the front wheel transmission 10, only one of the first and second release wires 14, 16 is pulled by depressing either the left or right handbrake pedals 12a, 12b, and the aforementioned operation is performed. A front wheel speed change operation structure for an agricultural tractor configured so that a lever 10a can be switched to an increased speed transmission state.
