The stator includes a stator core including a cylindrical yoke and teeth protruding radially outward from the yoke, an insulator fixed to the stator core, and coils each wound around a corresponding one of the teeth with the insulator in between. The insulator includes a first cover covering a first end face of the yoke in a first axial direction and a rib on the first cover and supporting a wire connecting the coils. The rotor includes a rotor core outside a periphery of the stator and a magnet fixed to the rotor core.

An electric work machine can appropriately detect rotation of a rotor. The electric work machine includes a stator including a stator core, an insulator fixed to the stator core, and a coil attached to the insulator, a rotor rotatable about a rotation axis and including a rotor core and a magnet fixed to the rotor core, a stator base supporting the stator, a sensor board supported by the stator base and including a magnetic sensor that detects the magnet, and an output unit drivable by the rotor.

A walking mechanism for driving a machine body includes a walking wheel group having a plurality of walking wheels attached to the machine body, with two front and two rear wheels relative to a traveling direction. The machine body has two sides with a pair of one of the front wheels and a one of the rear wheels being respectively located on each of the sides and driven to rotate synchronously. Each walking wheel includes an auto tire casing with a tread outer side having a tread pattern distributed along a circumferential direction of the auto tire casing. The tread pattern is configured as a plurality of tread ribs with a respective tread groove formed between each adjacent pair of the tread ribs, the tread pattern radiating outward from an axial center of the walking wheel. A related robot and self-walking mower are also disclosed.

Described herein are self-propel accessories for walk behind/push-driven machines/devices comprising: drive assembly motor(s) operatively connected to at least one power supply; at least one drive assembly for imparting drive from the drive assembly motor(s) to at least one accessory wheel assembly that is operatively connected to an output shaft of the drive assembly motor(s) and one of an axle or a drive engagement surface of the at least one accessory wheel assembly having accessory ground engagement wheel(s) coupled to at least one end of the axle for rotation therewith; a controller for the drive assembly motor(s) having an actuator for engaging the drive assembly motor(s); and an attachment assembly for coupling the drive assembly motor(s), the at least one drive assembly and the at least one accessory wheel assembly to a housing of the push-driven machine or device in place of a wheel assembly/sub-assembly of the push-driven machine or device.

A lawn mower includes a blade, a motor connected to the blade, and a housing storing the blade in the housing and is configured to mow grass underneath the housing. The lawn mower includes a grass container to contain the mowed grass and a connecting member that connects the housing to the grass container. The housing is provided with a ceiling opening communicating with a flow path inside the connecting member. The ceiling opening overlaps with a region corresponding to a rotation range, of the blade, projected upward along a drive shaft.

A grounds maintenance vehicle having a vehicle frame is disclosed. An implement is coupled to the vehicle frame and has a first implement end and a second implement end. A height selection tool is configured to select one vertical position of a plurality of selectable vertical positions, where each vertical position limits a distance between the implement and the vehicle frame. An implement angle selection tool is configured to change the elevation of the first implement end relative to the second implement end and fix the elevation of the first implement end relative the second implement end. The implement angle selection tool has a manually engageable mechanism configured to change the elevation of the first implement end relative to the second implement end when the implement angle selection tool is disengaged.

A work system includes a plurality of working machines each including a working unit; and a power feeding device configured to supply power to the plurality of working machines. The plurality of working machines includes a plurality of types of working machines different in amount of power required to drive the working unit. The power feeding device includes at least one first power transmission unit configured to wirelessly transmit power to a working area of the plurality of working machines. Each of the plurality of working machines includes a power reception unit configured to receive the power wirelessly transmitted to the working area.

The present disclose provides a combination of a piece of landscaping equipment moveable over a terrain, a laser, and a mounting assembly. The mounting assembly is configured to engage the laser to the piece of landscaping equipment. The laser is selectively operably to emit a laser beam across a portion of terrain that is located in front of the piece of landscaping equipment as the piece of landscaping equipment moves over the terrain. The mounting assembly is operable to adjust a position of the laser relative to the piece of landscaping equipment.
