Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concave clearance based on the crop being harvested to optimize threshing performance and minimize grain damage.
Belt and Chain Tension: Check belt and chain tension frequently and adjust as needed to prevent slippage and premature wear. Proper tension ensures efficient power transfer throughout the combine.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer regularly to remove debris and ensure proper separation of grain from chaff. Clogged sieves reduce harvesting efficiency.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations to prevent premature wear and failure. This is especially important for bearings exposed to dust and moisture.
