A working machine may include an operation rod; a tool disposed on a front portion of the operation rod; a prime mover configured to drive the tool; a first harness connector disposed frontward of a center of gravity of the working machine and configured to be connected to a first end of the harness; and a second harness connector disposed rearward of the center of gravity of the working machine and configured to be connected to a second end of the harness opposite to the first end. In a side view of the working machine, the center of gravity of the working machine may be positioned on a first harness connector side with respect to a plane that passes through a midpoint of a line connecting the first harness connector with the second harness connector and is perpendicular to the line.

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 riding grass mower includes a driver seat 11 in a travel chassis 10, a mower deck 30 supported by the travel chassis 10, a rotary blade 20 in a glass-cutting space defined by side wall and a top plate 31 of the mower deck 30, a blade motor 4 configured to supply motive power to the rotary blade 20, and a blade motor control unit 55 configured to control the blade motor 4. The blade motor control unit 55 includes a main drive control unit 55a configured to rotate the rotary blade 20 forward, an auxiliary drive control unit 55b configured to rotate the rotary blade 20 backward, and a drive selection unit 55c configured to selectively operate the main drive control unit 55a and the auxiliary drive control unit 55b at a start of mowing with use of the rotary blade 20.

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor; a driving circuit to transfer power from at least one of the energy storage devices to at least one of the motors; and a charging circuit to charge at least one of the energy storage devices. The riding lawn mower further includes a first identification terminal engageable with the second energy storage device and a second identification terminal engageable with the first energy storage device; the riding lawn mower identifies a type of the energy storage devices through the identification terminals and selectively connects them to the driving circuit and the charging circuit.

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.
