Abstract: This application belongs to the field of a garden tool and specifically relates to a garden tool including: a body; at least two traveling wheels located on two sides of the body; and a driving unit. The driving unit is installed inside the traveling wheel. In the present application, the driving unit is installed inside the rim. Therefore, the overall axial dimension of the traveling unit is reduced, the lateral width of the garden tool such as a mower is reduced. Under the same width conditions, more lateral space is available for the garden tool, allowing for the installation of structures such as battery compartments and standing platforms. This design lowers the center of gravity of the garden tool like a mower, thereby enhancing their stability.

Abstract: The invention relates to an adjusting device, which includes a lifting device for adjusting a position of an attachment in use and a locking mechanism.
