A self-aligning driveshaft coupler includes a receiving clutch mounted to a driveshaft and a locking clutch assembly mounted to an implement. The locking clutch assembly includes a collar and a yoke that rotate together, and a spring between the collar and the yoke. A locking pin may be pivotably attached to the yoke to move a projection on the locking pin in and out of the retaining groove. A plurality of drive pins extend axially from the collar. The spring biases the drive pins into engagement with the receiving clutch when the locking pin projection is in the retaining groove and the output shaft and receiving clutch are rotated less than 180 degrees.

An energy storage arrangement includes a shaft for transmitting torque, a housing, an actuator configured to be axially moved, a freewheel disposed between the shaft and actuator and fastened to the shaft, the freewheel being configured to transmit no torque in one rotational direction, an energy store configured to store torque, a support element, an outer coupling between the housing and the support element, and an inner coupling between the support element and the shaft.

A method for controlling engagement of a power take-off (PTO) clutch of a work vehicle may generally include transmitting, by a computing device, a control signal associated with initiating engagement of the PTO clutch, determining a clutch slippage energy generated during engagement of the PTO clutch due to clutch slippage and, while the PTO clutch is getting engaged, calculating a clutch engagement time remaining until engagement of the PTO clutch is completed based on the clutch slippage energy and a maximum clutch engagement energy associated with the PTO clutch. In addition, the method may include determining a torque command for controlling engagement of the PTO clutch as a function of the remaining clutch engagement time and controlling the engagement of the PTO clutch based on the torque command.

A clutch for an agricultural implement including a rotating unit for connection to a powered shaft, a selectively disengageable unit, a zero-backlash torque limiter operable in an engaged position where a biased plunger is housed in a seat to angularly connect the rotating unit and the selectively disengageable unit for torque transfer until a maximum torque level is reached; and in a disengaged position where the plunger is retracted outside the seat. Further, a safety occlusion mechanism having an obstructing element selectively movable in an obstructing position to hinder the seat from housing the plunger and in a release position to allow shape coupling when the plunger and the seat overlap. The occlusion mechanism is biased to switch in the obstructing position and the release position is instated by an operator.

A method for controlling power takeoff (PTO) clutch engagement includes determining an output clutch speed, adjusting a clutch current at a predetermined rate, estimating an inertial load of a PTO implement and adjusting the clutch current for one or more times at a time interval, and selecting a clutch control algorithm configured for the inertial load of the PTO implement.

An agricultural working machine, method, and power take-off transmission are provided. The agricultural working machine includes an internal combustion engine, at least one power take-off, and an arrangement for dynamically adjusting at least one of a speed and a torque of the PTO. The arrangement includes an electric machine and a transmission summing the driving force of the internal combustion engine and the electric machine. The transmission includes at least two gear elements that are magnetically coupled.
