Abstract

A seed brake for a pneumatic agricultural seeding and/or fertilizing machine. The seed brake comprises a curved tube having an inner curved side and an outer curved side. The inner curved side is provided with an opening. The inner curved side is also provided with a baffle located between the opening and the outlet of the tube. The baffle extends into the tube and is integrally formed with the inner curved side. The baffle is formed by kinking the tube.
