Pokey is right, it will help. It also will hurt you on level land because you have just overloaded the middle of your sieves from both sides. ac tried this same thing by using a big air delivery blower with a gravity controlled valve to always have the flow toward the lower side. The problem they all had around me (I am in big hills) was when the slope evened out the thing blew on both sides, narrowing the sieves and cutting capacity to less than what it was without anything at all. If you want the corn to lay evenly across the seives, you are going to need a self leveling machine. Big benefits to this are the grain tank can be utilized to it's fullest every cycle, field speed can be about max for whatever your machine is capable of at all times, and the operator is always sitting level, which has for me been an very comfortable feeling after a long day. big downside is a leveling machine is expensive. gs
