Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearance to ensure optimal threshing and minimize grain loss. Follow the manufacturer's recommendations for different crop types.
Belt and Chain Tension: Routinely check and maintain proper tension on all belts and chains to prevent slippage, premature wear, and potential breakdowns during harvest.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer frequently to remove debris and ensure efficient grain separation. Clogged sieves can lead to grain loss and reduced harvesting capacity.
