Patent

CA 2167123

A disc-type opener and seeder useful in direct seeding during zero-till operations includes index/presser wheels to prevent hairpinning of trash etc. A soil retainer wheel cooperates with the disc to close the furrow cut by the disc and to cover the seeds placed therein. All of the above wheels are adjustably mounted to a main frame together with a spring-biased furrow finishing wheel. Improved seed supply means designed to reduce seed bounce are provided. Multiple units are mounted to a tool bar. Minor modifications permit the opener/seeder to be installed on the shank of a chisel plow air seeder.
