For a long time, the harvest of cabbage still relies mainly on manual labor, which has low labor efficiency, high labor intensity, poor operation quality and high production cost.

[0003] Our company's Chinese utility model patent number is CN202220871201.9, which includes a header device, a power chassis and a cabbage transmission mechanism, and the gasoline engine provides power for the whole machine. The header device is located at the front end of the frame, the cabbage transmission mechanism is located in the middle of the frame, and the gasoline engine, the shift control box and the hand-held handle are located at the rear of the frame. The header device is modularly mounted on the front end of the frame as a whole, and can be controlled by a single button of the oil cylinder to flip and lift the header device relative to the frame; the tension wheel is designed to be movable in front and is kept on the same ground plane as the load-bearing wheel, which extends the contact area between the crawler and the ground, making the walking more stable and reliable; the whole machine is driven by a gasoline engine, and the walking adopts a hand-held integrated design. The whole machine has a compact structure, is small and light, has low cost and is easy to use.
