Provided is electric power equipment that allows a battery to be installed and removed with ease. The electric power equipment (1) includes a main body (2) defining a battery receiving recess (40) having an open upper end, and a battery (20) configured to be received in the battery receiving recess, wherein an upper part of a front end part of the battery is provided with a projection (108) projecting in a forward direction, and a rear end part of the battery is provided with a grip, and wherein an upper edge of the front end part of the battery receiving recess is provided with a supporting surface (36) configured to support a lower surface of the projection at least when the battery is being removed from the battery receiving recess.

A charging control system includes a lawn mower that has a battery and performs a lawn mowing work while traveling autonomously, and a charging station for charging the battery. The lawn mower includes a period calculator for calculating a shutoff period of supply power supplied from the charging station, and a first communication unit. The charging station includes a second communication unit communicating with the first communication unit, an information acquisition unit for acquiring shutoff period information indicating the shutoff period from the first communication unit via the second communication unit, a switch for shutting off the supply power, and a shutoff controller for controlling the operation of the switch. The shutoff controller releases the shutoff of the power supply to the lawn mower based on the shutoff period information.

An electric walk behind greens mower includes an electric reel motor rotating a cutting reel; an electric traction motor rotating at least one traction drive roller; and an electronic control unit commanding the electric traction motor and the electric reel motor to rotate at reduced speeds during a turn if an electronic signal indicates a deviation from a normal walk speed. The electric walk behind greens mower also may include a battery management system that activates a low voltage power supply if a key switch is turned from the off position to the run position, and that provides a start signal to an electronic control unit if the key switch is momentarily turned from the run position to the start position whereby the electronic control unit activates a high voltage power supply to the electric reel motor and the electric traction motor.

A method and kit for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.
