Abstract: A drive control system for a work vehicle is provided with a power transmission device that drives front wheels and rear wheels, a request determination unit, and a drive mode control unit. The power transmission device has a drive mode switching mechanism that performs drive mode switching between a four-wheel drive mode in which drive power is transmitted to front wheels and rear wheels and a two-wheel drive mode in which drive power is transmitted to only the rear wheels. The request determination unit determines a necessity for an increase in drive power on a contact area of the work vehicle, and outputs an increase request based on the determination result. The drive mode control unit outputs a drive mode switching request for switching to the four-wheel drive mode to the drive mode switching mechanism, in response to output of the increase request.

Abstract: A traveling vehicle includes: a body; a steering wheel that is attached to the body and rotates around a rotating shaft; and a forward-reverse switching lever that switches between a forward position, a neutral position, and a reverse position. The forward-reverse switching lever includes: a lever main body that is pulled up at the neutral position and swings forward or rearward in a pulled-up state; and a grip mounted to an upper portion of the lever main body, the grip includes: a base portion including an upper face; and a protruding portion protruding downward from the base portion, and the protruding portion includes: a distal face that is opposite a rotating-shaft side of the protruding portion; a first side face; and a second side face.

Abstract: A work vehicle transmission includes a first transmission mechanism that changes input motive power to any one of multiple speeds, and a second transmission mechanism that changes the motive power changed by the first transmission mechanism to any one of multiple speeds, the number of speeds of the second transmission mechanism being smaller than that of the first transmission mechanism. Multiple speed change multi-disc clutches of the first transmission mechanism are arranged parallel with multiple deceleration multi-disc clutches of the second transmission mechanism so as to be adjacent in the diameter direction thereof.
