Back to top Stripper Adjustments Combine settings vary from those recommended with a cutterbar. Worn or damaged components or skewed concaves should be corrected. To handle more rice, open sieves a bit wider and increase fan speed to increase airflow. In addition, check for good airflow distribution across the sieves. To extend the life of the stripping fingers, select a rotor speed that is just aggressive enough to remove all the kernels.
Losses increase as fingers wear.
Threshing rice from the stalk requires excessive rotor speed if worn fingers are not replaced. Wherever rice height differs, front hood and header height adjustments are profitable. The hood should contact rice heads at their midpoint. A gap between the hood and the rotor that is too wide or too narrow increases gathering loss. Harvester influence on rice yield and milling quality have been evaluated in an experiment.
