You can use your row crop head. You can't use a grain head unless you remove the reel and install sunflower pans. The head of the flower needs to be all brown and dry. We usually wait until it freezes to dry out the stalk. Drive as fast as you can because the machine will clean better when full. Power is not a problem. Check the book settings to begin, they will be close. Keep the air up on the high side of the suggested setting to prevent overloading the chaffer. Sunflowers will stand a long time but can go down with heavy rain when mature. Down or lodged sunflowers are a real mess. About impossible to pick up so get them when their ready.
