Settings need to be adjusted according to individual crop moisture and general conditions. Adjustments need to be made as the harvesting continues. Producers have found that canola, peas or bean settings for the cylinder and concave are a useful starting point for combining hemp. The air, sieve and chaffer are set similar to wheat, for a starting point. 

Proper setting of the combine improves the yield and quality of the grain and reduces wear on the combine. Experiment with ground speed, concave openings, air speed etc.

Following is a suggested starting point to set a combine for harvesting of hemp.  

• Cylinder Speed - 450 - 600 rpm
• Concave - 30 – 50 mm
• Wind - 1070 rpm
• Sieve - 3mm
• Chaffer - 10mm
