What the trick to getter a better sample when cutting sunflowers? Seed is dry but the stalks seem a little tough yet, but we've been getting a lot for wind and rain and the flowers are are going down pretty bad. I have a 2388 and had it set anywhere from 240 to 310 on rotor, 750 to 850 on fan, I'm use one small wire, 2 large wire concaves and the grates have covers on them. I suppose it would work better if everything was bone dry but I'm trying to get them before the all go flat. I'll probably try to get a row crop head and try it if more go down. If you have any experience your input would be appreciated.

I run rotor as low as it will go, fan 780, sieves according to manual, at least two narrow and one wide concave with seperator cover plates and concave indicator on 4. If you go more than that it opens a gap that crap can get through. It can be a royal pain when they get dry as stalks shatter and you get chunks of pith and stalks same size as seeds.

Broc,

normally we set the rotor on 240 to 260 rpm, use in the threshing area 3 corn concaves, in the seperating zone first one keystoch and then slotted grates. I actually do not know how dry your sunflowers are, as this is different to Europe. We usually use our small grain sieves to get a better sample. Upper sieve normally as wide open as a thump, lower sieve a little bit less, wind around 700 to 750.

Good luck
