A method for operating a power take-off shaft of an agricultural tractor with an attachment hoist includes providing a power take-off shaft spatially assigned to the attachment hoist, a hoist controller and a control unit. The method also includes detecting an operating state of the power take-off shaft via a first sensor and an upper operating position of the attachment hoist via a second sensor. The method further includes restricting the upper operating position to a first maximum value by the control unit if the first sensor detects that the power take-off shaft is not operating, and restricting the upper operating position to a second maximum value by the control unit if the first sensor detects that the power take-off shaft is operating, where the second maximum value is less than the first maximum value.

An example smart implement includes a power takeoff connector, one or more sensors, a controller, and a communication unit. The power takeoff connector attaches the smart implement to a tractor. The one or more sensors generate implement data. The controller is configured to determine operating parameters based on the implement data from the one or more sensors. The communication unit is configured to communicate with the tractor.

A working machine includes: a first generator having: a rotor to be rotated by power from a PTO shaft; a rotor coil provided to the rotor; and a stator coil to generate electricity when magnetizing current is applied to the rotor coil; a working device to be operated by the electricity generated by the first generator; and a converter device to convert surplus electricity not consumed by the working device into the magnetizing current to be applied to the rotor coil.

Embodiments include a flex wing cutter equipped with a splitter gearbox and a plurality of drivelines. Each driveline is coupled to the splitter gearbox via a clutch assembly, and supplies power to a drive gearbox and cutting blade assembly on a wing of the flex wing cutter. Each clutch assembly is equipped to an actuator, the actuator configured to selectively engage or disengage the driveline from receiving rotational power from the splitter gearbox. Each actuator can be remotely controlled from a control located in a cab of a towing vehicle, such as a tractor, allowing an operator of the flex wing cutter to remotely deactivate the cutting blade assemblies of either or both wings of a flex wing cutter.

An attachment assembly for connecting an agricultural implement to a tractor. The attachment assembly comprises tractor-side frame configured to extend from the tractor. The attachment assembly additionally comprises an implement-side frame configured to be removably attached to the implement. The implement-side frame is configured to rotate with respect to the tractor-side frame. The implement-side frame comprises connection elements configured to attach the implement to the implement-side frame. The connection elements provide at least four points of connection for the implement.

An adaptive operating device (1) for agricultural tractors includes two or more operating regions (2), each of which includes at least one manually operable operating element (3). The operating device (1) includes a detecting device (4) to detect the type of working apparatus (5) coupled to the tractor during use, a configuration device (6) cooperating with the detecting device (4) for configuring the functionality of an operating element (3) or operating region (2) for the type of coupled-on working apparatus (5), and at least one indicating element (7) of indicating a configuration of an operating region (2). Depending on the configuration, at least one operating element (3) can be changed with regard to its spatial position or can be configured with regard to direction or extent of movement.

Disclosed is a connection device for an agricultural machine, the device including: a front having an input shaft coupled with an input yoke and installed passing therethrough; a rear body having an output shaft coupled with an output yoke and installed passing therethrough; a joint part provided to allow each of the bodies to be coupled with each other and to be rotatable via center pins installed on central parts of upper and lower tip ends of each of the bodies; and a connection yoke fastening each of the input and output yokes thereto via “+” shaped bearings, wherein in the “+” shaped bearings, a length “L” of the connection yoke fastening shafts fastened to the connection yoke is formed to be longer than the length “l” of the input and output connection yoke fastening shafts fastened to the input and output yokes.
