Abstract: A work vehicle includes an engine, a transmission to change a received rotational force to a rotational force at a gear ratio that corresponds to a desired vehicle speed and output the changed rotational force, a first operating tool to change the rotation speed of the engine and a deceleration rate of the transmission, a rotation speed controller to control the rotation speed of the engine based on an input provided to the first operating tool, and a second operating tool to receive a holding instruction to hold the rotation speed of the engine constant. In response to the holding instruction being inputted to the second operating tool, the rotation speed controller is configured or programmed to disable control of the rotation speed of the engine which control is based on the input provided to the first operating tool, and hold the rotation speed of the engine constant in accordance with the holding instruction.

Abstract: A working machine has a display device including: an area display portion to display a setting area for setting the first priority value, the second priority value, and the third priority value; a first axis display portion including a first scale portion indicating the first priority value depending on a distance from the reference point; a second axis display portion including a second scale portion indicating the second priority value depending on a distance from the reference point; a third axis display portion including a third scale portion indicating the third priority value depending on a distance from the reference point; and a marker display portion to be indicated in a partial area corresponding to at least two of the first axis display portion, the second axis display portion, and the third axis display portion.

Abstract: A PTO shaft driving device in a working machine, includes a parking switch to detect parking of a vehicle body, a first switch located on a manipulator located on the vehicle body to output a PTO shaft control command that is either a driving command to drive a PTO shaft located on the vehicle body or a stopping command to stop the PTO shaft, a second switch located at a position different from the manipulator to output a PTO shaft control command that is either a driving command to drive the PTO shaft or a stopping command to stop the PTO shaft, a first permission switch to selectively permit or prohibit a stationary work when the parking switch detects the parking, and a controller configured or programmed to control driving of the PTO shaft. The controller is configured or programmed to selectively drive or stop the PTO shaft according to the PTO shaft control command from the first switch or the second switch when the stationary work is permitted by the first permission switch.
