Background
A lawn mower is a widely used outdoor tool that can level a lawn using mechanical force. The existing mower has some defects in weeding. For example, when a low-powered lawnmower is used, the rotational speed of the motor is small. At this time, if the grass or other vegetation in the lawn is dense, the impeller of the mower has low rotation speed, and the power shortage will cause low mowing efficiency. And if the resistance is too great when mowing, there is a risk of jamming, causing the motor to heat up and damage the mower. In contrast, when a high-power mower is used, the rotational speed of the motor is large. If the area of grass or vegetation concentration present in a lawn is small, there is a potential for wasted energy and when the impeller of the mower is rotating at too high a speed, it is prone to worker fatigue.
