Abstract: A grass trimmer includes a trimming head, a driving device for driving the trimming head to rotate so as to cut vegetation and an operating device for a user to operate so as to control the driving device. The trimming head includes a spool and a line holding element, the spool is used to wind a trimming line, and the line holding element is formed with a line holding structure. The driving device includes a motor. The grass trimmer has an auto-winding mode. In the auto-winding mode, the motor drives at least one of the spool and the line holding element to make the spool and the line holding element rotate relatively so that the trimming line is wound on the spool automatically.

Abstract: A self-propelled machine includes a drive motor, a handle having two grips, an electromechanical converting device, and a speed adjusting element configured to move relative to the handle to adjust a rotational speed of the drive motor and configured to be operated by a user when the user holds one of the two grips with a single hand. The speed adjusting element is disposed between the two grips. The electromechanical converting device is configured to convert a positional change of the speed adjusting element into an electrical signal for adjusting the rotational speed of the drive motor. The speed adjusting element is movable between a first position and a second position. The rotational speed of the drive motor when the speed adjusting element is in the first position is greater than the rotational speed of the drive motor when the speed adjusting element is in the second position.
