Abstract
Abstract An attachment for conventional seed planters which permits the planting of crop seed in sodded areas which may have been undisturbed for as many as 20 years. The attachment is selfdrafting; that is, no load weight must be applied to bring about proper ground preparation. The essential components are a semirigid curved foot immediately following a fluted disk colter. These are supported below a frame which has provisions for adjusting row width and has connections for standard three-point tractor hitches and corresponding attaching points on a seed planter unit.

A towed implement to be rigidly attached to the leading portion of a sod planter to prepare soil for the acceptance of seed and to draw an opener-runner of the planter into the sod a desired depth, which comprises: a frame substantially parallel to the ground having a leading edge and a trailing edge and being provided with means at the leading edge for releasably connecting the implement to a towing vehicle and at the trailing edge for releasably and rigidly connecting the implement to the sod planter; at least one ground engaging unit supported by the frame, comprising: a rotatable disk colter having radially-extending flutes alternately projecting at least three-fourths inch on each side of the disk colter; means attached to the frame for mounting the disk colter in a vertical plane below and perpendicular to the leading edge of the frame; a pivot member attached to the frame; a rigid foot supported on the pivot member in alignment with and rearward of the disk colter, the foot having an upper portion above the pivot member and a lower portion below the pivot member extending a greater distance below the frame than the disk colter and being curved forwardly in a substantially circular arc; a pointed pad attached to the extremity of the lower portion of the foot, the width of the pad being less than twice the projection dimension of each flute of the disk colter; and resilient means connected between the extremity of the upper portion of the foot and a rearward portion of the frame; and means on the frame for adjusting the ground engaging unit to a position whereby the foot and colter of the ground engaging unit are in alignment with the opener-runner of the planter.
