I had some issues last year harvesting wetter corn (above 22%) with the machine losing corn out the back. I run a 6 row 974 head. I usually run concaves at 10 to 11, fan at 1100, top sieve usually 5/8 and bottom at 3/8". Rotor speed in dryer corn I can run down to 570 (Love the 2 speed rotor option) up to 750. I wouldn't want another machine without 2 speed rotors. I guess it's pretty rare on an 86. I try to run 4 to 4.7 MPH. (Up to 220 bushel corn!) Is this too fast or slow? I try to watch the grain loss monitor to judge my speed.
Do any of you remove the beater grate covers for corn? I never have on this machine, but I did on my TR70, put it back in for soybeans. Just the back 1/2.
On some varieties of corn I seem to get small cob pieces in the grain tank. Especially white cob corn. I can't seem to get rid of them no matter what I do. It's mostly the end tip breaking off. The slow rotor speed helps some.
It does a great job on soybeans with a 20' 973 platform, just a little finicky on corn.
Any advice is appreciated, thanks.
