491647 Sunflower Seed Disc - 21 Hole Vacuum Seed Plate for Väderstad Tempo Planter

491647 Sunflower Seed Disc is a precision vacuum seed plate specially manufactured for Väderstad Tempo high-speed precision planters, dedicated for sunflower planting operations.

**Material features**: Constructed from rigid, low-friction wear-resistant engineered plastic. This material maintains stable rigidity and smooth surface under continuous vacuum suction and repeated seed contact. It resists abrasion, temperature fluctuation and deformation during long planting seasons, avoiding burr generation on the edge of seed holes.

**Product characteristics**: Optimized 21-hole layout precisely matched to sunflower seed dimension. The hole profile is carefully optimized for vacuum singulation, grabbing only one seed per hole to effectively reduce empty holes and double seeding. It supports high-speed field planting and keeps consistent seed spacing across the whole working width. Worn, scratched or deformed seed disc causes poor seed singulation, resulting in uneven plant population and yield loss.

**Compatibility**: Direct aftermarket replacement for OEM 491647, fully compatible with Väderstad Tempo F 6-8, Tempo K 24, Tempo L 8-24, Tempo L 8-32 Central Fill, Tempo R 4-6, Tempo R 12-18, Tempo T 6-7 and Tempo V 6-12 precision planter models. Clean the seed plate cavity, check knockout wheel and vacuum seal gasket before installation. Install 491647 sunflower seed disc to restore high precision singulation, improve planting consistency and get uniform sunflower emergence in the field.
