ABSTRACT OF DISCLOSURE The specification discloses an improved row cleaning apparatus to be mounted on a tractor-drawn planter unit to clean away mulch and crop residue without cultivation of the soil. The cleaning action of the present invention improves depth control and planting speed of the planter unit and facilitates seed germination while retaining the mulch and residue between crop rows for erosion control and yield enhancement. The row cleaner disclosed herein comprises a pair of toothed wheels journaled for rotation about intersecting axes mounted on the planter unit ahead of the furrow opener. The toothed wheels are mounted with their teeth intermeshed above the soil surface and rotate in planes symetrically inclined downwardly, outwardly, and forwardly of the direction of travel of the planter unit. The toothed wheels penetrate the soil ahead of the furrow opener to a depth sufficient for the forward motion of the planter unit to drive the wheels in rotation, thereby clearing mulch and drop residue from the path of the planter unit, yet not so deep as to substantially cultivate the soil. The advancing planter unit is thus presented with substantially bare, untilled soil.
