This invention relates to a planter guide attachment designed to hold and align conventional corn, soybean planters, or other units on the upper area of a ridge of soil formed by previous cultivation-ridging processes as known in Ridge-Till farming. The unit provides a mounting shaft having a pair of coned blades mounted thereon to allow the tapered faces of the disc blades to hug the sides of the ridges for proper planter alignment. The shaft blade construction is hingedly attached to a mounting bar which is vertically adjustably attached to a tool bar extending transversely of the rear of a towing vehicle for mounting a plurality of guide units thereon. A knee spring-action mechanism is provided to load the shaft, disc structure to maintain the same in ground contacting position, and allow the same to override obstacles that may be in the ridge, and thereafter return the same into ground-contacting position along the sides of the ridge. The knee action includes a counteracting spring having an adjustable actuating shaft attached to the disc combination. This counteracting spring mechanism is adjustable to permit a high lift factor to override obstacles and maintain downward pressure to bring the discs into ground engagement and into contact with the sides of the ridge. Scraper blades are also provided adjacent each of the discs for cleaning the same.
