摘要： A working vehicle includes: a clutch displaceable to a connected state in which power is transmitted to a drive, a disconnected state in which the transmission is disconnected, and a half-clutch state in which power is slidably and partly transmitted to the drive; a detector that detects an operation position of a clutch pedal and outputs a detected value corresponding to the operation position detected; a control device that brings the clutch into the half-clutch state if the detected value corresponds with a threshold, and brings the clutch into the disconnected state if the detected value is less than the threshold and into the connected state if the detected value is greater than the threshold, and vice versa; and a change unit that changes the threshold to a different value in accordance with an operation on the operation member.

摘要： Work vehicle having a coupling member which is switchable between a coupled state where left/right brake operation tools are integrally coupled and a released state releasing the coupling. A coupled state detector is utilized. A controller controls a traveling state and is switchable between a first or normal mode and a second or vehicle speed suppression mode. The second or vehicle speed suppression mode can be switched back to the first or normal mode when the coupled state is detected and a predetermined releasing operation is performed.

摘要： A working vehicle includes a traveling clutch to be switched between an engaging state and a disengaging state, a brake to brake the traveling device according to an operation of a brake operator, and a controller to perform a braking control to perform the braking, and an auto-switching controller to switch the traveling clutch from the engaging state to the disengaging state. The controller performs a first processing to switch the traveling clutch from the engaging state to the disengaging state when the brake operator is operated in a case where the auto-switching control is valid and a vehicle speed is less than a threshold, and a second processing to prevent the traveling clutch from being switched from the engaging state to the disengaging state even when the brake operator is operated in a case where the vehicle speed is equal to or higher than the threshold.
