摘要： A transmission device for a work vehicle includes an auxiliary transmission including forward gear shift stages for the work vehicle to move forward and a reverse gear shift stage for the work vehicle to move backward. The forward gear shift stages include a low-speed gear shift stage with a largest gear ratio among the plurality of forward gear shift stages, and a medium-speed gear shift stage with a gear ratio closest to a gear ratio of the reverse gear shift stage among the forward gear shift stages.

摘要： In a work vehicle, a through-hole in a stay includes first and second regions. When a grip is pulled in an unlocked state in which a collar is located inside the first region and a grip assembly is not locked inside the through-hole, a state is transitioned into a locked state in which a compression spring is compressed by a pin and a plain washer, a brake lever rotates, a claw moves toward a notch, and a rod is located inside the second region and the grip assembly is locked inside the through-hole. When a brake pedal is stepped on in this locked state, the claw and the notch engage with each other, and the brake pedal is locked.

摘要： A vehicle pedal structure includes an accelerator pedal swingable about a swing shaft inclined with respect to a width direction in a top view of a traveling vehicle, and a mechanical link to convert swinging of the accelerator pedal into sliding in a front-rear direction. The link includes a first link structure and a second link structure that include first and second swings and first and second rods. Each of a first end and a second end of the second rod is restricted from sliding along an entering-exiting direction. In the link structures, in the top view, a second angle of a second swing shaft with respect to the width direction is smaller than a first angle of a first swing shaft with respect to the width direction.
