| 摘要 | An agricultural tillage blade having a central opening is adapted to be disposed on a shaft for rotation to cut trash and penetrate into the soil. The blade has an outer periphery substantially in the shape of a sine curve formed about a circle. The outer periphery of the blade is sharpened to more easily penetrate the soil and cut trash. | ||||||
