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.

Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ε) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ε) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ε) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ε) insisting on the cardan (3) is obtained according to the formula: ε=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).

A power take-off PTO connection mechanism (100) for mid mounted tools (101) of a utility vehicle (1000 includes three main assembly members: a frame attachment mechanism (108), a vertical moving frame (or cradle) (106), and a PTO assembly (128). The frame attachment mechanism (108) is fixed to the frame of the vehicle or tractor (1000). The PTO connection mechanism (100) of the present invention helps is easy and quick connection of the PTO shaft to a variety of tools (101) with the tractor. The PTO shaft remains in continuous contact with the tool power input once it is moved in an engaged position.

An attachment structure of a generator and a working machine including a transmission case; and a PTO shaft protruding from the transmission case, includes a structure body attached to a side of the transmission case from which the PTO shaft protrudes, and includes the generator attached to the structure body.

A support assembly for a trailered implement includes an implement support link that is moveable between an implement support position and a stowed position, and a shaft support link that is coupled to the implement support link via an intermediate link. The shaft support link is moveable between a first support position and a second support position. When the implement support link is disposed in the implement support position, the shaft support link may be disposed in the first support position to support and position the rotatable shaft at a first height relative to a ground surface. When the implement support link is disposed in the stowed position, the shaft support link may be disposed in the second support position to support and position the rotatable shaft at a second, lower height relative to the ground surface.

According to the invention, PTO connecting apparatus is provided. According to the invention, this comprises a vehicle PTO connecting device from which an accessory equipment PTO connecting device according to the invention is releasable and nonpositively connectable and couplable.
