Abstract
A seed drill planting apparatus includes an opener configured to plant a row of seeds at locations corresponding to the wing tips of the openers and a row of fertilizer at the center of the opener. The press wheels for the opener are constructed of a pair of skewed wheels that are arranged to throw soil inwardly to provide a proper cover for the rows of seeds and fertilizer placed into the ground by the opener. The skewed press wheels are connected to an adjusting mechanism that is operable to selectively vary the angle at which the press wheels are skewed with respect to the direction of travel. A one-way castering wheel is also provided to function to caster for tight turns on the side of the implement at the inside of the turn, but automatically locks into a stable position when the implement is converted into a transport position.
