Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concave clearance to ensure optimal threshing and minimize grain damage. Consult the operator's manual for specific settings based on the crop being harvested.
Belt and Chain Tension: Check the tension of all belts and chains before each harvesting season and throughout the season. Loose belts or chains can lead to slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to prevent blockages and ensure efficient grain cleaning. Adjust the sieve settings based on the size and density of the harvested grain.
Bearing Greasing: Follow the recommended greasing schedule for all bearings, especially those in the header, threshing cylinder, and cleaning system. Proper lubrication extends bearing life and prevents costly breakdowns.
