Hello. More questions. Have a specialty rotor with gordon bars in front, small wire concaves with every other wire pulled because they have a more square edge than the large wire that were in there. Plan on using cover plate on front half of concave. Front two grates are keystock and back is slotted without the bars attached to it. Gordon airjet chaffer. I have either 4 or 8 straight bars in the middle of the rotor mainly for corn. Would I be ahead to take these out and put spiked rasp bars in for wheat harvest? My understanding is these straight bars only help in high yielding corn and hurt everything elso, efficiancy, power consumption etc...Expect 50+ bushel soft red winter wheat. What do you think, thanks in advance. P.S. Anyone use Gordon airjet wheat chaffer for k-31 fescue harvest? I am going to try it soon.
