[0064] When using, Figure 8 As shown, adjust the height of the adjusting block 9 on the slide rail 12 so that the cutting wheel 14 reaches the height of the lawn to be mowed, and then tighten the bolt 10 to fix the adjusting block 9; start the motor 7 to drive the cutting wheel 14 to rotate clockwise; Figure 6 As shown, the cutting wheel 14 cooperates with the rake teeth 15 to mow the lawn. The cut grass clippings enter the storage box 4 through the feed port 16 due to the inertia of the cutting wheel 14. During the mowing process, the staff can observe the content of the storage box 4 through the cover plate 3. When the storage box 4 is full, it can be opened as shown in FIG. Figure 1 The second buckle 13 shown is used to open the baffle 11 along the hinge, and the storage box 4 is taken out to replace the storage box 4; the storage box 4 opens the first buckle 2, the cover 3 swings upward, and then the grass clippings in the storage box 4 are cleaned.
[0065] The above scheme can effectively solve the problem that the grass clippings after mowing will be scattered on the ground and need to be cleaned manually, thereby reducing labor and saving time costs; by raising and lowering the wheels 8, the specific height requirements of different lawn types and mowing needs can be met; the installation of the rake teeth 15 can also prevent foreign objects such as stones on the lawn from damaging the cutting wheel 14, thereby increasing the service life of the lawn mower.
