What Environmental Factors Can Cause Seeding Error %

Seed Stuck in Seed Disc

• Error repeats in one row with a pattern (e.g., 20% error on a 5-hole disc = one hole clogged).
• Solution: Clean clogged holes.

Seed Clogged in Tube or Valve

• Seeds stop dropping; visible in funnel-to-valve tube.
• Solution: Clean tube and test valve in Manual Function Test (page 4.3).

Dirt on Light Sensor

• Dust makes seed detection harder, raising error %.
• Solution: Keep sensor clean, set threshold ~97%, lower for tiny seeds.
