If your struggling to close the seed slot, the Needham Ag Poly 20 Point Crumbler Wheels together with the Needham Ag Angle-Changer are a good option, especially if most of your acres are no-till.
The Poly 20 Point Crumbler wheels are 1/2″ thick and 13″ in diameter. They are more aggressive than the factory closing wheels and the Needham Ag 2×13” wheels and they perform best in residue covered no-till conditions, especially moist soils. The Poly 20 Point Crumbler Wheels reach down through the residue better to pull the seed slot closed. The poly wheels also have a small amount of flexibility which really helps shedding mud in higher moisture soils.
The Needham Ag Poly 20 Point Wheels come standard with a heavy duty hub and the PEER® SeedXTreme Bearing.
We don’t recommend adding the Poly 20 Point Crumbler wheels to a Case 500/500T without the angle changer, as the factory arm runs too straight and it doesn’t have the necessary gathering action to utilize the wheel.
