Abstract
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.

A method of refurbishing a handheld landscape power tool, comprising:
- providing the handheld landscape power tool, the handheld landscape power tool including:
- a tool head, the tool head including a tool shaft;
- and
- an original power head having a complementary configuration to the tool shaft, the original power head including an original motor;
- separating the original power head from the tool head;
- providing a replacement power head, the replacement power head including:
- a motor;
- and
- a power shaft mechanically coupled to the motor of the replacement power head, wherein the power shaft lacks a complementary configuration to the tool shaft;
- providing a shaft coupler, separate from the tool head and the replacement power head, the shaft coupler including:
- a power shaft connecter configured to be capable of being mechanically connected to the power shaft;
- a shaft-specific connecter having a complementary configuration to the tool shaft, configured to be capable of being mechanically connected to the tool shaft, the shaft-specific connecter being mechanically coupled to the power shaft connecter;
- and
- a coupler housing, wherein the power shaft connecter and the shaft-specific connecter are rotationally supported in the coupler housing;
- coupling the shaft coupler to the tool head, including connecting the shaft-specific connecter to the tool shaft;
- and
- coupling the shaft coupler to the replacement power head, including connecting the power shaft connecter to the power shaft.
