Abstract

The invention discloses a self-driven mower. The self-driven mower comprises a main body of the mower, a plurality of rollers for supporting the main body of the mower, a motor for driving at least one roller, an operating lever of which one end is connected with the main body of the mower rightly, and a control device for regulating the self-driving operation of the mower. The control device comprises a holding handle movably arranged on the operating lever, and an electronic control device, wherein the holding handle can move between the first position where the rotating speed of the motor of the mower is zero and the second position where the rotating speed of the motor is more than zero relative to the operating lever; and the electronic control device detects the position of the holding handle and regulates the speed of the motor according to detection results. The self-driving operation of the mower can be controlled conveniently; and the mower walks steadily.

Description

technical field [0001] The invention relates to a lawn treatment appliance, in particular to a self-propelled lawnmower. Background technique [0002] Usually, outdoor gardening cutting tools such as lawn mowers are provided with operating levers for pushing, and a switch box and a control mechanism are provided on the operating levers near the gripping part for easy operation and control by the operator. The mower relies on the thrust applied by the operator to the operating rod to travel on the ground and perform cutting operations, and the labor intensity for the operator to operate this push-type mower is very high. The lawn mower with self-propelled function no longer requires the operator to push hard. This type of lawn mower is provided with a drive motor to drive the front or rear rollers of the lawn mower. The control mechanism can control the speed or retreat of the mower. [0003] U.S. Patent No. 5,442,901 discloses a speed regulation control scheme for a self-p...
