Product Description
PA303940 Seed Brake is a critical friction wear part installed inside the seed meter of Great Plains grain drills. This seed brake controls the rotational speed of the seed metering wheel, limits overspin, prevents seed dragging and reduces double seed drops during planting. Made from durable friction composite material, it resists abrasion and maintains stable braking performance under continuous field operation. Worn seed brakes cause inconsistent seed spacing, skips or multiple seeds per hole, which directly impacts crop stand and yield. It is a direct aftermarket replacement for OEM PA303940. Compatible with Great Plains no-till grain drills including Solid Stand, 2SF,3SF and 3PD series. Clean the seed meter housing and inspect seed wheel wear when replacing this seed brake. Install PA303940 seed brake to restore accurate seed metering, achieve uniform seed placement and maximize emergence for wheat, oats, barley and other small grain crops.
