Angle sensors 15 are fixed to the inside of the electronic throttle pedal 6 and the top of the toothed disc body 8, respectively. The angle sensor 15 is electrically connected to the control board 5. A lawn mower 16 is fixed on the top surface of the frame assembly 2. The lawn mower 16 is electrically connected to the control board 5. A delivery tube 17 is detachably provided at the output end of the lawn mower 16. A collection box 18 is detachably provided at the rear side of the frame assembly 2. A vacuum cleaner 19 is fixed to the right side of the outer wall of the collection box 18. A connecting pipe is fixed between the vacuum cleaner 19 and the collection box 18. The output end of the vacuum cleaner 19 is fixedly connected to one end of the delivery tube 17.

[0024] During use, the lawn mower moves forward or backward in a straight line by stepping on the electronic accelerator pedal 6 (the electronic accelerator pedal 6 contains an angle sensor 15). The system uses a lithium battery as a power source. The electronic accelerator pedal 6 outputs a signal to the control board 5 according to the different stepping angles. The control board 5 processes and calculates the signal, and then outputs the signal to the left and right travel motors 3. The left and right travel motors 3 change the speed according to the received electrical signal data (at this time, the speeds of the two travel motors 3 are the same), thereby controlling the speed of the left and right tires to control the travel speed of the lawn mower. The lawn mower turns by rotating the steering wheel of the steering machine assembly 1. The steering pinion 7 at the lower end of the steering wheel drives the toothed disc body 8 to rotate. The toothed disc body 8 realizes the steering of the front wheels through two sets of connecting rod mechanisms. An angle sensor 15 is installed on the toothed disc body 8. According to different rotation angles, the angle sensor 15 will output different signals to the control board 5. The control board 5 processes and calculates the signals, and then outputs the signals to the left and right travel motors 3.
