    摘要: A tillage element for use in a plough, harrow or the like is described which comprises a disc having a substantially planar portion and an inclined flange portion extending from the periphery of said central portion, an abrupt transition being provided from the central portion to the flange portion. The tillage element provides better penetration, inversion of soil and improved ploughing as compared with a conventional disc plough having concavely curved rotary discs. The invention also relates to tilling apparatus using a-plurality of such tillage elements and description is given as to how the tillage elements can be used in such apparatus in combination with a leg provided with a point with the tillage element being pivotable readily between positions, permitting both left- and right-hand ploughing alternatively to be carried out.
