Combines N6 CONCAVE

Pete, Have you tried a faster cylinder speedIJDepending on cob size,hardness,or sponginess,slow cylinder speeds can give you broken cobs.Also,too wide of concave clearance can give you broken cobs.Try one thing at a time,but first try 300-350rpm to see if that helps.Then try a 7_8" concave setting to see if that helps.Sounds like you are close,just a little fine tuning. Good luck, Hyper Harvest II

Pete - keep playing around with settings like Hyper suggests, maybe you'll hit it right. But the biggest factor we have noticed is the hybrid itself. Some hybids just have soft cobs that will break up no matter what you try. Dryer corn seems to be somewhat better too. We were having the same problem as you with our R52 last week - cob break-up, comming through concave with wires removed and overloading our shoe. Slowed us down to 3 mph at places. That corn was 20%. The past two days, we've been cutting corn ranging from 30 - 36% and rolling out whole cobs, very little shoe load other than grain and flying along at 5 mph in 180 bu corn. limiting factor for us in these conditions is clean grain elevator. Funny thing is, this corn is some cheaper no-name variety while the soft cobbed stuff was Pioneer. Keep tryin'!

Pete, I don't think cutting every other wire out is going to add a bunch to shoe load. Have you tried slowing up rotor all the way. We run 200 RPM alot of the time with 19% or less moisture. It may be the distance from crossbars down to the wires more than anything if it is you concave doing the breaking. Not much you can do with that without replacing with hi wire concave or plaining yours down. Which chaffer do you haveIJ Can you run chaffer closed more without loss or if there is loss open it back up and shut down sieve a bit. Good luck. Dan
