3 Terms and definitions

The following terms and definitions apply to this document.

Rolling lawn punching machine rotatinglawnaerator A punching needle is radially arranged along a radial direction of a knife roll or a cutter head, and a gasoline machine drives a knife roll or a cutter head through a mechanical transmission, depending on the weight of the machine the force causes the punching needle to penetrate into the soil, forming a tubular cavity on the flat bed, and is a machine for ventilating the flat bed.
