Abstract
A drawbar packer having an adjustable bias assembly which transfers implement weight between the wheels and the coil packers. Tension on extension springs is adjustable so that sufficient weight is transferred from the wheels to the coil packers such that the wheels pack soil less than the coil packers. In this way, the implement packs soil uniformly in preparation of the seed bed.
