Abstract
An opener assembly for an agricultural seeder has an opener disc attached to an opener subframe for rotation about an axis. The opener disc is angled to the direction of travel to create a furrow for depositing seeds. A boot is mounted to the opener subframe beside the opener disc for preventing loose soil from falling into the furrow ahead of seed deposited therein. The boot contacts and scrapes the opener disc and creates an enclosure between the boot and the opener disc. A flexible seed bounce flap provides the rear wall of the enclosure. The boot has a lower edge that fits entirely within the furrow created by the opener disc. A seed tube having a lower end extending into the enclosure is mounted to the opener subframe by a bracket independently of the boot. A structure is also provided for limiting downward movement of a firming wheel arm.
