Combines Chaffer size in Beans on 1660

We have the adjustable airfoil for both the chaffer and the lower sieve. We got them from loewen and if you are going to get an airfoil, I would suggest the adjustable over the fixed. In beans the adjustment is critical in that if the setting is a little too tight for the size of the bean, the crop plugs up the openings and you have to stop and open them up a little. A tiny little change in the lower sieve setting (one notch, or 1_2 of a number) will take us from running a full return at less then 2 mph to basically no return at 4 mph. That gives you an indication of how precise the adjustment is. This combination with the fan deflector usually gives us a sample that looks like it's ready for the planter. I can send you some pictures if you like. Mike

Check out Gordon's AirJet Chaffer before you buy a new chaffer. Just click the "AirJet Chaffer" spot at the left.

I was having the same trouble. I bought an Air-Jet chaffer. I set the shoe seive and the wind wide open. I then set the concaves as tight as possible and use cover plates on the front 1 1_2 concaves. The results are amazing and near perfect. Sure cuts down the stress of having to "tweak" all the time. Works the same way on wheat with the different screens. Takes about 10 minutes to change over. Naturally, I was skeptical and the price of about $1500 deterred me for awhile. I looked at it as a long term investment. Don't think you'd be sorry!

Stosh, Couldn't have said it any better, as I have used the AirJet for the first time last fall. JWK
