AH223756 Feed Accelerator Stone Trap Beater Wheel - FAST System Beater Wheel for John Deere STS Comb

AH223756 Feed Accelerator Stone Trap Beater Wheel is a critical rotating wear component for the FAST (Feed Accelerator and Stone Trap) feeding system fitted on John Deere STS series rotary combine harvesters.

**Material features**: Fabricated from high-strength wear-resistant alloy steel with surface hardening treatment. It has excellent impact resistance and abrasion resistance to withstand continuous impact from crop stalks, grain and field stones during long harvest seasons. The optimized blade profile maintains structural integrity under high-speed rotation and heavy material loads, resisting chipping and premature wear.

**Product characteristics**: As the core beating wheel of the feed accelerator assembly, it pushes and spreads incoming crop material evenly before entering the rotor threshing section. Meanwhile, the optimized wheel geometry deflects rocks and heavy foreign objects down into the stone trap chamber, preventing hard debris from entering the expensive rotor and concave assembly. Worn, cracked or deformed beater wheel leads to uneven crop feeding, blockages and failure of stone separation, risking catastrophic damage to the combine’s internal threshing components.

**Compatibility**: Direct aftermarket replacement matching OEM AH223756, fully compatible with John Deere STS combine models: S660, S670, S680, S685, S690, S760, S770, S780, S790. Inspect bearings and seals, fully clean stone trap chamber and feeder house debris during installation. Install AH223756 beater wheel to restore stable feeding performance, improve stone protection and avoid costly combine downtime during harvest.
