The invention discloses a self-powered mowing machine which comprises a mowing machine main body, a plurality of rollers for supporting the mowing machine main body, a motor for driving at least one roller and a transmission clutch arranged between the motor and the driving rollers, wherein the transmission clutch comprises a first clutch element, a second clutch element, an operating rod and a control device; the first clutch element and the second clutch element can be selectively meshed or separated; one end of the operating rod is connected with the mowing machine main body; the control device is used for controlling the self-powered operation of the mowing machine and comprises a holding handle of which a pivot is connected with the operating rod; the holding handle at least comprises three positions; when the holding handle is positioned in the first position, the self-powering speed of the mowing machine is zero; when the holding handle is positioned in the second position, the self-powering speed of the mowing machine is greater than zero; and when the holding handle is positioned in the third position, the first clutch element and the second clutch element are mutually separated and the self-powering speed of the mowing machine is zero. The self-powered mowing machine is labor-saving in operation and has good stability and a better human-computer function.
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 wheels of the lawn mower. The control mechanism can control the speed or retreat of the mower. [0003] U.S. Patent No. 4,835,949 discloses a self-propelled propulsion system that is cont...
