AI Technical Summary
Technical Problem
Existing gardening tools require manual operation to control their movement, which is user-unfriendly and places a heavy mechanical load on them, affecting their lifespan.
Method used
The automatic driving system uses a combination of clutch and electric motor drive to enable automatic propulsion and idling of gardening tools. It uses back EMF to detect the stop standard and automatically switches between forward and reverse rotation modes, reducing the electric motor speed to achieve user-friendliness and extend service life.
Benefits of technology
It achieves high user-friendliness and long service life for gardening tools, eliminating the need for manual operation, reducing mechanical load, and improving the ease of operation and durability of gardening tools.

Abstract
Method for operating a garden appliance and garden appliance. The invention relates to a method for operating a garden appliance having a drive system with a clutch, which is configured to be automatically engaged by forward rotation to propel the garden appliance and to be automatically disengaged by reverse rotation to freewheel the garden appliance, an electric motor drive system, which is configured to rotate the clutch in forward and reverse rotation, and a user-activatable signaling device, the method having the steps of a) operating the electric motor drive system in a freewheeling and / or braking operating mode by changing the signaling state of the signaling device in a user-activated manner to reduce the motor rotational speed, b) detecting whether a counter electromotive force or a variable based on the counter electromotive force caused by the electric motor drive system meets a stop criterion, and c) operating the electric motor drive system in a reverse rotation operating mode to rotate the electric motor drive system in reverse in order to disengage the clutch to freewheel the garden appliance if the stop criterion is met.
