Would like to know where ya'll set your vanes for hi yield corn, 16-24% moisture. Will have 4 straight bars on seperator portion of rotor. '07 7010.
Ran 2388's for a long time, vane position was important, ran a 8010 last yr. and dealer said vanes were not an issue, leave them alone.
Want to free up as much hp. as possible w/o screwing corn out the back.

Why are you installing the straight bars?
2003 and 2004- 8010's had straight bars. All the 2005 to 2007 machines have spiked rasps in the rear separating area of the rotor instead of straight bars. It was discovered the machines worked better this way and hp consumption was greatly reduced.
CNH combine field rep said their testing proved it, he said the spiked rasps worked to keep the rotor cage more open and results in better separation, at least in a 7010/8010.
The 88's seemed to require four bars but the 7010/8010 don't, I have also found that the rotor rpm can be set faster in corn on a 7010/8010 than an 88 and not see rotor loss like the 88 would. The rotor cage is much more open in the 7010/8010 than the 88 series cage.

medium with at least 2 sets of round bars concaves. had not heard about the spiked rasp bars round bars will make it a monster and grain quaility will be superb. i run a 12 row on a 8010 in heavy irrigated corn round bars help alot

Midwest; Was planning on running the factory large wire, small wire setup w/ 4 bars over the seperator. That is what made the 2388 perform w/ a 12 row. With the cage being more open on the 7010 makeing that big of a difference, then it sounds like I don't need the straight bars. Just go w/ some round bar modules and leave the spikes on? Ran over a million bu. through an 8010 last year w/ some round bar modules and 4 bars, right front module was plugged the whole time. Was short on hp. Maybe I'll go w/o bars and have them put some round bar modules in. NC IL corn is around 24 to 25, not seen anyone out yet.

All the guys near me run the Kuchar grates in at least the front set of concaves in the 80-7010s. They say it pretty well eliminates the the plugging in the front right module and is more gentle on the grain. Our dealer put them in our 7010 but I can't give much firsthand knowledge yet.

Did about 10acs of some 104day corn this morning to make sure everything works and to get some corn to feed the hogs. Was running right at 200bpa at around 24%.

Not really sure how they perform in beans as compared to corn firsthand yet, but they must work good because the guys around me do not switch them out between corn and beans. After the little I have combined so far it looks like they help a lot in corn. There is no plugging on the front concaves at all. Not sure what conditions would be the worst for this? Wet or dry stalks? There is no green left in my stalks on this number and it was about 24%M.

with a high powered combine like a 70-8010, one set of concaves might not do the trick use round bars in the second position right hand side if it shells easy use two. NO interrupter bars in a 70- 8010 put spiked bars over the back tried and true everyone thinks they make a better mouse trap. be prepared to change bettween corn nad beasn for top performance

we started on the 11th with a 7010 12 row. tried a couple of fields with moisture 21-24% running around 220-250 wet. we did alot of pissing around trying to get everything set. first there was a problem with the software and we could only start counting acres manually and when it started we were counting acres way to fast according to the moniter we did like 14,000 acres on day one. got the new software in on day 2 and fixed that. we were haveing a terrible problem trying to set the machine we shifted the cage to left and it helped but it would still randomly just start pouring corn over the sieve on the left side, on day 3 we finally got 2 sets of round bars modules and it is an entirely different machine now. not sure how they got by with the just large wire before in good corn just seems to be night and day difference in our findings.
