摘要：
A tillage apparatus includes a wheeled frame configured with a plurality of concave blades arranged in a plurality of longitudinally extending columns and transversely extending rows. The rows are longitudinally spaced apart by a progressively increasing distance. The blades of each column are transversely tilted alternately to the left and right. The blades of each column are transversely offset from one another to create a swath of tilled ground along the width of the column. In operation, soil is thrown left and right between successive blades of a column to till the soil across the width of the column and leave a substantially level soil surface.
