A grass trimmer includes a cutting head for mounting a cutting member, a drive head having a output shaft for driving the cutting head to rotate, and an anti-winding member for preventing the output shaft from being wound to by grass. The drive head includes a drive device to drive the output shaft and a head housing for accommodating the drive device. The output shaft connects to the cutting head and passes through the anti-winding member and the anti-winding member is mounted to the cutting head so as to rotate with the cutting head and is disposed between the cutting head and the head housing so as to fill the space between the cutting head and the head housing.

A trimmer has a guide tube and a tool unit connected to an end of the guide tube. A handlebar is secured to the guide tube and has handles connected to a respective end of the bar of the handlebar. Each handle has a shaft with a fastening end and a free end. The fastening end is provided to secure the handle on the power tool. The handles each have a front side facing the tool unit of the guide tube end and an oppositely positioned rear side. The handles each have an inner side and an outer side, wherein the inner sides face each other and wherein the outer sides face away from each other. At least one of the handles is provided with a heel of hand support designed as an elevation extending at the inner side and at the rear side of the shaft.

A system in one aspect of the present disclosure includes a battery pack and an electric work machine. The battery pack includes a battery, a first interface, a first memory and a first controller. The first controller is configured to transmit battery data identifying a type of the battery pack. The electric work machine includes a motor, a second interface, a switching element, a manual switch, a second memory and a second controller. The second controller is configured to transmit electric apparatus data identifying a type of the electric work machine.

A blade has a flat body with a first side, a second side, an aperture extending between the first side and the second side, and an outer peripheral edge. The aperture has a central axis defining an axis of rotation. A plurality of teeth is formed along a portion of the outer peripheral edge forming a cutting edge. Each of the teeth has a tip that is a radial outermost part of the flat body in a plane defined by the tip and the central axis of the aperture. The cutting edge has a first end and a second end. The distance between each tip of the teeth increases from the first end of the cutting edge to the second end thereof. The distance between each tip and the central axis increases from the first end of the cutting edge to the second end thereof.

A job-site tool in one aspect of the present disclosure includes and a display. The display is configured to display information regarding the job-site tool. The display includes a circuit board, at least one light emitter, an electric conduction member, at least one lens, and a resin member. The at least one lens is provided on the circuit board to cover the at least one light emitter. The resin member includes a lens cover area that covers surroundings of the at least one lens to thereby secure the at least one lens to the circuit board, and an electric conduction cover area that covers the electric conduction member.

A work apparatus includes a housing, an electric motor arranged in the housing, the electric motor including a rotor shaft driven rotationally about a rotor axis, an output shaft for driving a tool, the output shaft being connected with a form fit to the rotor shaft on a receptacle of the rotor shaft, and a flange supported on the housing. The rotor shaft is mounted rotatably via a rotor shaft bearing arranged in the flange, the rotor shaft bearing extending along a bearing section in the direction of the rotor axis, and wherein the output shaft extends at least as far as the bearing section of the rotor shaft bearing.

An arm support tool attachment includes a shaft extending from a first end to a second end; a clamp positioned at the second end of the shaft, the clamp to removably secure to a handle portion of a tool; and a cuff having an elongated channel to receive and support a user’s arm, the cuff attached to the shaft at the first end; the shaft extends the cuff away from the handle portion of the tool such that the cuff provides user support.

A method of refurbishing a handheld landscape power tool includes separating an original motor of the power tool from a tool head of the power tool. The tool head includes a tool shaft extending proximate to the original motor. A replacement power head and a shaft coupler are provided. The replacement power head includes a motor and a power shaft mechanically coupled to the motor. The shaft coupler includes a power shaft connecter coupled to a shaft-specific connecter. The replacement power head is coupled to the shaft coupler by connecting the power shaft connecter to the power shaft of the replacement power head. The tool head is coupled to the shaft coupler by connecting the shaft-specific connecter to the tool shaft of the tool head.
