ある作業車の変速操作構造。 This is a speed change operation structure for a work vehicle that is connected with a ground work device 5, which allows movement of a speed change operation lever 14 for traveling from a high speed side to a low speed side, and allows the movement of the operation lever 14 from a low speed side to a high speed side. A check mechanism B that prevents movement of the control lever 14 is provided on the operation frame 16 that supports the operation lever 14. A restraining device 20 that is movable to an avoidance posture that is evacuated from a position, and a low-speed side lever receiving portion 20 of a protruding portion of the restraining device 20 in a protruding posture.
A stop member S that prevents a from moving toward the high speed side
Further, the high-speed side lever receiving portion 20b of the protruding portion in the protruding posture is configured to be movable out of the operation path 19 by an external force acting on it toward the low-speed side. The gear change operation structure of a working vehicle.
