An agricultural machine configured to be operated by an operator and including a drive mechanism having a drive shaft and a gear assembly for driving an agricultural implement. The agricultural machine includes a slip clutch that has an outer sleeve operatively coupled to the gear assembly, an inner sleeve positioned within the outer sleeve and coupled to and rotatable with the drive shaft, a plurality of torque-transfer members positioned between the outer sleeve and the inner sleeve and configured to selectively couple the inner sleeve to the outer sleeve, and a position sensor in communication with one of the plurality of torque-transfer members and configured to output a signal in response to radial displacement of the one torque-transfer member being detected. The agricultural machine includes a control unit in communication with the position sensor and configured to alter an operating parameter of the machine in response to receiving the signal.

A garden tool power system comprises a motor, a reducer and a transmission shaft. The motor transmits the power to the transmission shaft through the reducer to drive wheels on the transmission shaft. The reducer comprises a pinion connected to an output end of the motor and a gear engaged with the pinion. The transmission shaft includes left and right shafts connected with each other through a connecting shaft. The gear mounted on the connecting shaft has at least two guiding rods transversely located thereon and two centrifugal blocks located between the guiding rods. Each guiding rod has a spring surrounded therearound and each spring located between two centrifugal blocks has two opposite ends respectively abutted against the corresponding portions of the centrifugal blocks. A fixing sleeve provided on the periphery of the centrifugal blocks is mounted on the transmission shaft and has buckle structures matching with the centrifugal blocks.

An agricultural baler including a flywheel and a drivetrain for coupling the flywheel to a connector that is arranged to be connected to a power take-off (PTO) of a tractor. The drivetrain includes a decoupling mechanism for decoupling the flywheel from the connector in case of an overload. The decoupling mechanism includes a controllable member that is movable between an engaged state in which the flywheel is coupled to the connector and a disengaged state in which the flywheel is decoupled from the connector. The decoupling mechanism further includes a detector configured for detecting the overload. The detector is configured for providing an overload signal to the controllable member triggering the controllable member into the disengaged state.

A dethatcher includes a frame having front and rear ends, a cover coupled to the frame and configured to selectively move between an open position and a closed position, a handle extending from the frame, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the cover is in the open position, a user may access the cutting reel from a top end of the frame.

A pickup unit of an agricultural baler that includes a reel with a plurality of tines configured for lifting a crop material from a field, the reel is rotatable in an operating direction and a reverse direction, and a drive system configured for driving the reel. The drive system includes a gearbox configured for receiving motive power from a power take off (PTO) shaft, a drive shaft operably connected to the gearbox, and a first clutch connected to the drive shaft. The first clutch is configured for operably disconnecting motive power to the reel so that the reel is manually rotatable as the PTO shaft remains operably engaged with the gearbox.

The present disclosure relates to an agricultural operation vehicle comprising a body; a transmission; a clutch pedal; a hand lever; a clutch switch; a clutch link unit connected to the clutch such that the transmission is fastened and unfastened from the clutch; a clutch pedal link unit coupled to the clutch link unit to rotate around the connecting shaft; a pedal link unit connected to the clutch pedal link unit and the clutch pedal so as to rotate the clutch link unit around the connecting shaft responsive to manipulation of the clutch pedal; a clutch switch link unit coupled to the clutch link unit to rotate around the connecting shaft with the clutch link unit; and an operation unit for rotating the clutch switch link unit around the connecting shaft such that the clutch link unit is rotated around the connecting shaft responsive to manipulation of the clutch switch.
