Turbo, We will try and help all we can.How many kerrnels_sq.ft. are you losingIJ We have been running in 180-200bpa.corn @ 26% moisture.19-24 kernels in a 12 inch band width across an 8-30(20ft.) corn head.Two kernels_sq.ft. or 40 total kernels equals a bpa. Our goal 1_2-2_3 bpa.20 kernels would be 1_2 bpa. .25% loss,some say 3% is acceptable,we don't think so.Concave,no wedge 7_8 inch front and back(check it with a 7_8 nut).If your concave rods are an inch apart,remove every other.Seperatreing grate,if your seperateing grate rods are an inch a part remove everyother also.Many concaves plug the inward corner as well as part of the grate with shucks.Add (two)F concave rasp bars to the front of the seperateing grate,(it takes two to span the full width of the seperateing grate).Bolted to the rods.If losses are still high add a flat bar 1_2 inch high by 3_4 inch wide full width bolted to the bottom of the grate bach against a cross bar.I'm sure you are running the extended cylinder bars and helicials.Our grate has narrow rods,we've left all the rods and cut loose everyother cross bar then drove them back and welded to the next remaiming bar. Try some different rotor speeds we are running 360 rpm as the cobbs are still very soft and kernels do not release easy yet.Maybe hyper II will have a couple more commentsIJ Report back. Good luck turbo. Hyper

Turbo, Check all the items that Hyper suggested.A couple of more things to double check.Make sure that inside of seperating grate is flush with inside of cage.In corn_soybean this needs to stay put.You mentioned that you are running a staggered lo bar configuration on the third and fourth row.We tried running a staggered(zig-zag pattern)with low bars and didn't feel we got the seperation needed.We then started running two lo bars side by side,with every other row lo-bar and remaining having two regular bars side by side.This would be worth a change if you are indeed running staggered setup.Definitely get another F2 toothed concave bar installed and have a flat bar as Hyper mentioned made up and ready to install.Give us some feedback on actual losses and if it is heavier on the left.Play with rotor speeds as(How wet is cornIJ)with higher moisture sometimes slower rotor speeds will tend to carry out with the shucks and trash.You mentioned having the high wire concave and seperator grate,what is the wire to wire dimensionIJ Don't give up as this system does work!

My sep. grate is flush with the cage. My wires are 1 5_8 on center. 1 1_4 apart. Does the high wire sep. grate not thresh as wellIJ I thought it would roll through the cobs better. Should I put the low bars on the same row as the discharge paddle or on the row with cylinder bar all the way to the end of the cylinderIJ I was running the cylinder around 280 Beacause of kernel damage. My corn moisture is between 20 and 30 percent in the same field. 25-125 bushel. We had a drought. I beleive the corn is coming out the on left side of the discharge as you can see it when driving along side in the grain cart tractor. Rotor loss is to much when it is more than a stock machine. I did not count it. It is real hard to find behind the stock machine. But the sample is dirtier and it does not have as much capacity.

Turbo, If both the concave and the sep. grate are 1 5_8" on center,then do not remove any wires.The high wire sep. grate is to help lower resisitance as material moves across it.The sep. grate should not be used for threshing,100% threshing should be done at concave.I usually install lo-bars so that they line up with the four remaining paddles and standard bars line up with extended cylinder bars into discharge.Have you reset the concaveIJ Open concave to 8 setting on outside,then set front eyebolts to one mark below mid position(torwards max),this should put you close to 1" at the front.Then lower rear of concave to 1" clearance at the back.When running in corn that has varying yield,it will be hard to keep machine full.This is one reason to add one more F2 toothed concave bar and also have that piece of flat bar stock (1_2" tall by 3_4"wide)ready to put in. let us know how you end up.

Turbo, With highly varible yields and moisture run a little tighter concave to insure complete shelling.Are you running low bars or worn bars,the only reason I'm asking is to make sure you have nearly a 3_4 inch difference in heightIJ If this was our machine we would cut everyother cross bar on the seperateing grate and drive it down to its nearest neighbor and reweld,this would lengthen the opening for more seperation time.Cut a stalk or stick to a 12 inch length,then we get on our knees and slowly work our way across our header width counting kernels or beans.Count both machines.It would be good to know exactly the difference. Thanks!! Hyper

Hyper Do you really mean 3_4"IJ I thought a hi_lo bar configuration would only result in 5_16 to 3_8 inch difference. What is the part no. for the F barsIJ Can they be used even if the separator grate hasn't yet had the cross bars cut and relocatedIJ Have a safe harvest

Me too. The original bars are only 1 inch high. If I have to take 3_4 inch off there would only be 1_4 inch remaining. There would not be any rasps remaining. I guess my bars were not wore out enough. I have the rotor out again and am grinding away. I have ground them down so there is about 1_2 inch height difference. My low bars were just wore on one side. probably not enough. I hope this fixes my problem. I also have put the low bars all on the same row. I am going to move the f rasp bar from the bottom to the front of the sep grate. If I put it at very front on the left side it will be right against the helical I installed. Is this okayIJ I also have ordered another f bar to put in the right side. I saw mentioned about using a reverse bar bolted to the grate. I looked at this but thought there was not very much clearance between the cylinder bars and the reverse bar bolted on the sep grate (regular bar not ground down). Just wondering because I have those on hand.

Turbo, Tooth height on the lo-bars should be 5_16".Normal height is 5_8".You wouldn't think this would do much, but it is enough to releive the pressure of the mat of material going through processor to let grain get dislodged from trash.That is where the F2 toothed thresher bar(71142277)or flat bar stock(1_2"x3_4")comes into play by stirring material over the sep. grate.Disreguard the the reverse bar on the sep. grate,too close to cylinder bars is right and not proven here yet. Good luck, Hyper Harvest II
