Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance based on the crop being harvested. Proper concave settings ensure optimal threshing and minimize grain loss.
- Belt and Chain Tension: Inspect belt and chain tension regularly, especially before and during the harvest season. Loose belts or chains can lead to inefficiencies and potential damage.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to prevent buildup of crop residue. Clogged sieves and chaffers reduce cleaning efficiency and increase grain loss.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings on the combine. Proper lubrication extends bearing life and prevents costly downtime.
