The present invention provides a clutch and a work machine having same. The clutch comprises an input member for receiving a driving force and rotating, an output member for outputting rotational motion, and at least one transmission member. The input member has at least one radially extending protrusion. The output member has at least one transmission engagement part. The transmission member is movable between a first position of engagement with the transmission engagement part and a second position of disengagement, being located in a path of rotation of the protrusion, and able to abut the protrusion and be driven to move to the first position. Displacement of the transmission member between the first position and second position has a radial component. According to the technical solution of the present invention, the function of automatically switching between transmission states according to the operating state of a prime mover can be achieved. The fact that displacement of the transmission member comprises a radial component helps to reduce the axial thickness of the clutch, so that the structure thereof is more compact.

A mower is provided and includes: a case; a charging circuit provided in the case, and a combination of a wheel assembly and a charging interface assembly arranged on the case. The combination is electrically connected to the charging circuit. The combination includes: a wheel assembly; and a charging interface assembly electrically connected to the charging circuit. The wheel assembly and the charging interface assembly are integrated molding structure.

An electric riding lawn mower includes a seat for a user to ride, a main frame to support the seat, a power output assembly including a mowing element to output power to realize mowing function and a first motor to drive the mowing element, a walking assembly to at least drive the electric riding lawn mower to travel in the direction of a first straight line on the ground and a second motor to drive the walking assembly, and a power supply device to power the electric riding lawn mower with a first battery pack, which includes a first battery pack housing and a plurality of battery cells disposed therein. The power supply device is mounted to the main frame. At least one of the first battery packs of the power supply device forms a pluggable connection with the main frame. The battery cells are lithium batteries.

An autonomous vehicle (e.g., mower) includes two or more wheels supporting a chassis upon a ground surface. A cutting motor powers at least one cutting blade, and a cutting frame supports the cutting motor relative to the chassis. The cutting frame is movable, relative to the chassis, to allow adjustment of a height-of-cut of the cutting blade relative to the ground surface. First and second guide rods are operatively attached to the chassis and are received within corresponding first and second apertures of the cutting frame to guide movement of the cutting frame. Biased bearings associated with the cutting frame may bias associated bearing members against the guide rods.

A self-driving device system includes a self-driving device, a charging station, and an adapter. The self-driving device can automatically walk and operate in a work area. The charging station is configured to charge the self-driving device. The adapter is configured to convert utility power to a low-voltage alternating current and output the low-voltage alternating current to the charging station. The charging station includes at least an input interface and a first output interface. The input interface is configured to connect to the adapter to receive the low-voltage alternating current. The first output interface is configured to output the low-voltage alternating current to the self-driving device. The self-driving device includes a charging interface. The charging interface is configured to receive a low-voltage alternating current.

A knife drive assembly for use in a harvesting header may be mounted near the center line of the cutter bar of the header. Mechanical power from the power unit behind the header (typically the combine power output shaft) may be translated for application to two knife assembly sections in the cutter bar at the front of the cutter table. Movement of the two knife assembly sections with this apparatus can be fully synchronized and 180 degrees out of phase, to maximize cutting effectiveness and minimize vibration of the header. The unitary drive assembly may allow for rapid repair and manufacture, and the size and weight of the knife drive assembly may represent a significant weight and balance advantage over the prior art.

A semiautonomous robot. The robot includes at least two powered locomotion devices and a monocular capture unit. The at least two locomotion devices are designed to rotate at least the capture unit about a rotational axis, which is situated in a fixed position relative to the capture unit, the capture unit and the rotational axis being set apart from each other. The robot further includes at least one control and/or regulating unit for ascertaining a distance traveled. As a function of a movement of the capture unit about the rotational axis fixed during the movement, in particular, at a known distance from the rotational axis and/or in a known orientation relative to the rotational axis, the control and/or regulating unit is configured to determine a distance conversion parameter, which is provided for ascertaining the distance traveled.
