A drive system for an agricultural work machine having a primary drive system configured to drive a performance system for performing a crop preparation or handling operation including a fluid motor, a fluid pump and a tensioner system. The fluid motor is configured to produce a drive force and to be driven by a flow of fluid moving through the motor. The fluid pump is operatively connected to the fluid motor and is configured to drive the fluid motor. The tensioner system is operatively connected to the fluid motor and to the fluid pump, wherein the direction of fluid flow through the fluid motor adjusts the application of at least one force applied to a belt in the drive system. The fluid motor is configured to adjust the force applied to the belt by regulating a belt tension in proportion to a torque provided by the fluid motor.

Work vehicle includes a traveling device. A speed changing device speed-changes a driving force of the engine and transmits the speed-changed force to the traveling device. A belt transmission mechanism transmits the driving force of the engine to the speed changing device. A belt tension clutch switches over the belt transmission mechanism between a transmitting state and a non-transmitting state. A brake operating tool effects a braking operation of the traveling device. A coupling mechanism activates the belt tension clutch.

The purpose is to provide a working vehicle such that, when a reverse switch coupler is detached, or when a wire connecting a reverse switch to a control device is disconnected, driving of a PTO shaft can be reliably prevented and reliability of the reverse switch can be improved. In a tractor, a reverse switch includes a normally closed type first contact, and a normally open type second contact that is switched in association with the first contact. When an input voltage from the first contact is higher than a set voltage, and when the input voltage from the first contact is lower than the set voltage and an input voltage from the second contact is equal to or lower than the set voltage, a control device controls the actuator such that the PTO clutch is disconnected.

A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved.

A clutch for a mower has an electric motor, a drive mechanism connected with the motor and an output mechanism connected with the drive mechanism. The drive mechanism has a cam driven by the motor and a cam follower reciprocating along with the cam. Reciprocation of the cam follower switches the output mechanism between a transmission state and a non-transmission state.

A transmission device and an agricultural harvesting machine include a first drive input element, a second drive input element, a shift sleeve configured as a hollow shaft, and a drive output shaft. The shift sleeve is mounted axially displaceably on the drive output shaft and is configured to be moved by axial displacement into one of a first position, a second position, and a third shift position. An internal toothing is formed on each of the first drive input element and the second drive input element. An external toothing and an internal toothing are formed on the shift sleeve. An external toothing is formed on the drive output shaft.

An agricultural machine includes an engine for power delivery, at least one axle provided with two wheels, a handlebar and a power take-off. The agricultural machine further includes a hydromechanical clutch group interposed between the engine and the at least one axle and a first and a second lever associated with the handlebar controlling the hydromechanical clutch group. The hydromechanical clutch group includes a actuation piston hydraulically controlled by the first and second lever movable between a first raised position, in which the actuation piston imposes to the hydromechanical clutch group the transmission of the motion from the engine to the wheels and to the tool, and a second lowered position in which the actuation piston frees the hydromechanical clutch group by kinematically disconnecting the engine from the wheels and the tool.
