The working principle of a lawn mower is to use the power of a gasoline engine to drive the mowing disc to rotate at high speed through the transmission system, causing the grass rope to adjust and rotate synchronously, generating a certain cutting force to cut the weeds. The main technical points of using a lawn mower include selecting the length of the straw rope based on the spacing between orchard plants and the height of weeds, using both hands to hold the handle, and maintaining a certain degree of inclination. When using a lawn mower to cut grass, be careful not to use a lawn mower when it is damp. Regularly clean and maintain the lawn mower
