Abstract
A ridge tillage attachment for conventional row-crop planters for use in minimum tillage planting on row ridges is disclosed. This ridge tillage attachment includes a tool portion and a linkage portion. The linkage portion has a parallelogram linkage support system and is attached to the planter. The tool portion is detachable from the linkage portion and is in the form of a tool support beam with guide wheels, cutting discs and sweep plates mounted thereto. The linkage portion of the unit is designed so that it can remain attached to the planter after the tool portion has been detached. An adjustable compression spring down-pressure system acts directly above the tillage implements to apply maximum down pressure. The guide wheels can be adjusted relative to the tool support beam by a height adjustment structure located directly above the wheels. The cutter discs are slightly offset to prevent plugging between them and to facilitate penetration of the soil. The V-shaped sweep is formed by interchangeable reversible plates to increase the life of the plates.
