When the first control lever 32 is pressed from the first initial position to the first predetermined angle to the first set position, the first switch 344 is triggered, and the main blade motor is started to drive the mowing blade. In this embodiment, the first predetermined angle is 15 °.

When the first control part 320 of the first control lever 32 is released, the first control lever 32 automatically rotates to the first initial position by the restoring force of the first elastic member 346, the first switch 344 is turned off, the electric circuit of the main blade motor is cut off, and the control part of the first control lever 32 stops working, and the mowing blade stops.

The operation method for starting self-walking comprises the following steps:

first, the power-on switch 3430 on the first display panel 343 is pressed to power on the lawnmower 100; then, the second control part 330 of the second lever 33 is pulled, so that the second lever 33 rotates clockwise in conjunction with the second cam 355, and the second cam 355 gradually presses the second elastic piece 3541 and the second elastic piece 356 of the second switch 354 to be compressed. When the second control lever 33 is pressed to a second set position from a second initial position by a second predetermined angle, the second switch 354 is triggered, and the self-propelled motor drives the road wheels 20 to walk. In the present embodiment, the second predetermined angle is 20 ° and is greater than the first predetermined angle (15 °), in other words, the rotation angle when the first control portion 320 rotates from the first initial position to the first set position is smaller than the rotation angle when the second control portion 330 rotates from the second initial position to the second set position.

The traveling speed of the traveling wheels 20 can be adjusted by pressing the traveling speed adjusting switch 3530 on the second display panel 353. When the second control unit 330 is released, the second lever 33 automatically rotates to the second initial position by the restoring force of the second elastic member 356, the second switch 354 is turned off, the electric circuit of the self-propelled motor is cut off, and the portion controlled by the second lever 33 stops operating, and the self-propelled motor stops.

After the first control lever 32 or the second control lever 33 which is pulled down is reset, the alarm exclamation point lamp is turned off and returns to the normal operation state.

The starting logic of the main knife motor is as follows: press the power-on switch 3430 on the first display panel 343 and pull down the first control lever 32 within 15 seconds; next, if the power-on switch 3430 is pressed again within 3 seconds, the main knife motor operates; after 3 seconds, the power-on switch 3430 is pressed again, and the whole machine is powered off.

Shutdown logic of the main knife motor: the first control lever 32 is released and the main knife motor is stopped. When the main blade motor is in operation, the power-on switch 3430 is pressed again, and thus no function is performed. After shutdown, the power-up state may be maintained for 10 seconds.

Eco (energy saving mode) logic of the main blade motor: the power-on default is an automatic mode, the power-on default is switched to an Eco mode (energy-saving mode) by pressing the energy-saving switch 3431, at this time, the Eco mode indicator lamp is turned on, the Eco mode is cancelled by pressing the energy-saving switch 3431 again, and at this time, the Eco mode indicator lamp is turned off.

Self-propelled logic of self-propelled motor: when the power-on switch 3430 is pressed, the self-propelled indicator lamp is fully turned on within 5 seconds, the speed of the last shutdown is defaulted after 5 seconds, and the self-propelled speed can be set arbitrarily within 10 seconds. If the second control rod 33 is pulled down within 10 seconds, the self-propelled motor operates; if no action is carried out within 10 seconds, the whole machine is powered off.

The self-walking speed adjusting switch 3530 can set the self-walking speed as follows: 2km/h, 2.5km/h, 3km/h, 3.5km/h, 4 km/h.
