Abstract
Abstract A seed drill has a hoe point operable to create a furrow and a fertilizer feed shank to apply fertilizer in the furrow. A seed tube is operatively positioned behind the hoe point and fertilizer feed shank within the furrow and is vertically adjustable relative to the fertilizer feed shank and hoe point. An adjustable hoe bed provides vertical movement of the hoe points and seed tubes relative to the main frame of the seed drill. An adjustable banding cup adaptor meters the feed of fertilizer to either the fertilizer feed shank or the seed tube. V-shaped packer wheels create V-shaped soil compaction which allows for water retention and plant protection.
