A power take-off shaft system for an agricultural vehicle includes an output shaft with a socket for a power take-off shaft stub located at one end of the output shaft, wherein the power take-off shaft stub is arranged in the socket. 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 is adjustable between a first position and a second position. The control valve includes a second piston arranged on the first piston, where the first piston is adjustable into a neutral position by the second piston.

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.
