A high-efficiency blade for a lawn maintenance tool includes a central axis and a mounting portion located on the central axis. The high-efficiency blade includes a cutting blade and a cutting blade sharpened leading edge. A cleaning blade is vertically offset from the cutting blade and is configured to mulch the associated clippings from vegetation and reduce an associated accumulation of clippings on an underside of an associated mower deck. The lawn maintenance tool can also include a deck having a separation distance between the cleaning blade and an underside of the deck. The deck can include an elevation change to vary the separation distance. The deck and high-efficiency blade can also include a forward or rearward tilt.

The present invention is directed to a battery powered mower with a low profile design that minimizes the height of the mower to make the mower easier to operate and store. The low profile design places the cutting blade motor in the center of the deck volute so that it doesn't extend above the volute. Additionally, the batteries do not include a cover and so holes are located within the housing to drain away any water that collects. The invention also covers a simplified manufacturing process for the terminal blocks for the battery and a rear door. Lastly, the invention includes a cable guide to prevent the electrical cable from pinching when the handle is folded for storage.

A turf maintenance apparatus having folding handles facilitating compact storage is presented herein. The folding handles can be compressed or extended to adjust overall length and can rotate between an extended operator position and a folded storage position. Depending on implementation, the folding handles can be locked in the folded storage position and can also lock in the extended operator position. One or more operator presence devices can disable operation of a motor or engine when deactivated. A first operator presence device can deactivate operation of the motor or engine when the folding handles are not locked in the extended operator position, and a second operator presence device can deactivate operation of the motor or engine absent an operator maintaining activation of the second operator presence device.

An electric work machine includes coils formed reliably. The machine includes a stator, a rotor rotatable about a rotation axis, and an output unit drivable by the rotor. 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 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.
