I STARTED BEANS TODAY.ADJUSTED EVERYTHING AS CHART IN BOOK SAID. SEEMED LIKE I WAS GETTING SOMEWHAT A LOT OF PODS IN TANK. TURNED UP FAN SPEED BUT NO HELP. THE ROTOR IS RUN IN LOW GEAR. WHAT WOULD HAPPEN IN HIGH.NEED ANY HELP I CAN GET.

Pods in the tank are not threshed, and the lower sieve is too far open. They should be going to the tailings return. If a higher fan speed took them out, there would be a lot of beans blown out as well.

I thought rotor should be in high for beans. You need to increase rotor speed, and or close the concaves. Unless you are having a lot of splits I would increase rotor speed until they become unacceptable. Another option is to retard the vanes to move the crop slower which is a pain. You can close the sieve slightly to return the pods for rethreshing, however this tends to reduce air flow to the chaffer and could hurt capacity.

Set rotor to 650rpm (that"s about max on low side) and fan 1050-1100rpm and concaves at #2-3, maybe even at "hard thresh" setting. In the 20 yrs we had a 1640 and now a 2166 I only used the high side once or twice and that was in green stem beans and ran 750rpm. I"ve always had the sieves set by the book and really never had to adjust them much from there recommendations.

When you mention "pods in the tank" are you getting unthreshed pods or just open pods that are threshed? It will make a big difference in what you do to control your problem. If it is simply open, threshed pods then you need more air. If you have a lot of unthreshed pods you have an underthreshing condition. You should get very, very few unthreshed pods as far as your return elevator. There may be a few that bounce that far but if you are getting more than a few you are underthreshing your beans. Tighten your clearances and/or speed up your rotor to take care of this, REGARDLESS of what the book says. The book is only a starting place, not gospel. Mike

Run rotor on high side and close concave all the way. If you start busting beans leave concave closed and slow rotor speed.
