Maintenance Tips

Concave Adjustment: Regularly check and adjust the concave clearance to ensure proper threshing and minimize grain damage. Consult the operator's manual for recommended settings based on the crop being harvested.
Belt and Chain Tension: Inspect all belts and chains for wear and proper tension. Loose or worn belts/chains can cause slippage, reduced performance, and potential damage.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer regularly to prevent buildup of debris, which can reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Lubricate all bearings according to the manufacturer's recommendations. Proper lubrication extends bearing life and prevents premature failure. Pay close attention to header bearings, as these are often exposed to dust and moisture.
