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 work machine comprises a work unit that performs work on a travel path, an internal combustion engine configured to generate power for driving the work unit, a traveling unit including a front wheel and a rear wheel, an electric motor configured to generate power for driving a first wheel of the front wheel and the rear wheel, and a first clutch for switching between transmission and discontinuation of the power from the internal combustion engine to a second wheel of the front wheel and the rear wheel.

A work machine determines, when a request to restart an engine is made, whether or not a reason indicated by stop information stored in a memory is a reason related to locking of the work portion. The machine sets an operation mode of the engine and a work portion to a safe mode if it determines that the reason indicated by the stop information is a reason related to locking of the work portion. The safe mode is an operation mode for lessening damage resulting from causing the engine and the work portion to work during the work portion locked or damage resulting from an object coming into contact with the work portion during the engine and the work portion working.

A dual powered riding lawn mower including a riding mower. The riding mower includes a mowing deck having at least one mowing blade therein. The mower blade is connected to a blade shaft. The blade shaft is connected to a clutch and gear box. The gear box will enable a user to switch between manual power and a battery powered motor. The manual power will include a set of pedals that will spin the blade shaft and propel the riding lawn mower forward. When the electric motor is engaged the pedals are used to charge the battery via an alternator connected to the gear box.

A drive train for driving a working unit of a self-propelled harvester is disclosed. The drive train includes a selectable belt drive with a drive belt, which operationally combines a drive belt pulley and an output belt pulley. The output belt pulley of the belt drive is operationally connected to the working unit via a drive shaft. The drive train comprises a clutch system, combining the functions of a belt clutch and an overload clutch into a single construction unit, with the response characteristic of the overload clutch system being hydraulically adjustable.
