A method of operating an agricultural vehicle including a range gearbox, an independent PTO system driven from an auxiliary drive shaft and a ground speed PTO system driven from an output shaft of the range gearbox. The method includes transferring torque from the auxiliary drive shaft to the output shaft of the range gear box via the independent PTO system and the ground speed PTO system while drive to the range gearbox is interrupted during a change in the range gear.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

A power take-off shaft system includes an output shaft with a socket for a power take-off shaft stub located at one end of the output shaft. A control valve is arranged in the output shaft and includes a valve bore extending axially from the socket into the output shaft. A first piston is adjustably arranged inside the valve bore in the output shaft, and a shifting element is adjustably controlled by the first piston. A first gearwheel and a second gearwheel are disposed in engagement with the output shaft via the shifting element such that the first piston moves between a first position and a second position. The control valve includes a second piston arranged on the first piston, and the second piston is adjustable such that movement of the first piston into the second position is blocked by the second piston.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

An auxiliary power take-off assembly in an automatic transmission of a motor vehicle provided with a torque converter, having a transmission input and transmission output having a drive shaft at the transmission input that is permanently connected to a drive motor of the motor vehicle via a pump shaft of the torque converter. A transmission output shaft at the transmission output, and a transmission chain includes at least one drive element and one output element. The output element can be connected to an additional unit to be driven. A switch element, which is arranged so as to act between the drive shaft and the drive element of the transmission chain for optionally connecting the drive shaft to the drive element. The drive element and the output element are designed as gearwheels which are engaged with one another without an intermediate wheel.

A vehicle is operable in a first mode in which vehicle actions are controlled in response to inputs received by an input device carried by the vehicle from an operator while being boarded on the vehicle and in a second mode in which vehicle actions are controlled in response to inputs received from the operator while the operator is proximate the vehicle, but no longer boarded on the vehicle. The vehicle carries a sensor configured to output a sensed input, as sensed by the sensor, from the operator proximate the vehicle, but not boarded on the vehicle. The sensed input is recognized and associated with a vehicle action and control signals are output to the vehicle based on the sensed input to cause the vehicle to carry out the vehicle action.

A work vehicle is provided with a support member that supports an output shaft of a wheel differential mechanism between a differential case and a planetary reduction mechanism. The support member is configured to engage the output shaft relatively immovably in a direction along the axis of the output shaft.

A method of selectively controlling a power take-off (PTO) assembly includes positioning a clutch assembly radially between a shaft and a PTO gear, operably controlling the clutch assembly with a controller, and selectively engaging the clutch assembly with the controller. The controller monitors signals received from a plurality of sensors and compares the monitored signals with respective signal thresholds. The clutch assembly is engaged when the compared monitored signals are within the signal thresholds.

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.
