I am having trouble with my 2166 spreading chaff or bean hulls. When I have a lot of material running thru such as 60 bushel beans I have no problem or when material is heavy, (for example when a rain shower makes things tough)I have no problem. When running a short crop and material is dry the bean hulls will not spread and end up piled in the middle of the 20' swath. What modifications can be done to get the bean hulls to spread out on the ground and for that matter even wheat straw was doing the same thing in wheat harvest. Than You.
