Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance based on crop type and conditions to optimize threshing performance and minimize grain damage.
- Belt and Chain Tension: Inspect belt and chain tension regularly. Loose belts or chains can slip, reducing efficiency and potentially causing damage.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to prevent plugging and maintain optimal cleaning performance. This will minimize grain loss out the back of the combine.
- Bearing Greasing: Regularly grease all bearings according to the manufacturer's recommendations to ensure smooth operation and prevent premature wear.
