摘要:
This invention is directed toward a combination cutting blade/raking device where the blade portion slices weeds off under the soil, thereby effectively killing the plant, and a raking portion collects the uprooted weeds. The blade and rake also flatten the surface of the soil. The raking section of the invention can be lifted independently of the cutting blade. The cutting blade is reversible so a user of the invention can cut twice as much area before having to remove the blade for sharpening. The blade is slightly curved in cross section, allowing for a smoother cutting path through the soil
