[0027] In the further implementable manner of the embodiment, several anti-winding grass blades 204 are evenly distributed on the outside of the blade shaft 201 along the circumferential direction of the blade shaft 201.
[0028] In the embodiment, several anti-winding grass blades 204 are evenly distributed on the outside of the blade shaft 201 along the circumferential direction of the blade shaft 201, and the spacing of each anti-winding grass blade 204 is equal, to ensure uniform cutting of weeds during rotation, avoid local overload, further improve the tillage efficiency and durability of the anti-winding grass blade 204.
[0029] In a further implementation form of the present embodiment, the cutting edge of the grass-entangling-preventing blade 204 is at an acute angle with the tangential direction of the rotation of the blade shaft 201.
[0030] In the present embodiment, the cutting edge of the grass-entangling-preventing blade 204 is at an acute angle with the tangential direction of the rotation of the blade shaft 201, which is designed to make the grass-entangling-preventing blade 204 easier to cut into weeds when rotating, reduce resistance, improve cutting efficiency, ensure the stability of the grass-entangling-preventing blade 204 in high-speed rotation, prolong the service life, and further improve the overall plowing performance.
