Did anyone else see the corn harvest Sept. 1 at the Farm Show? The 9120 had a 16 row head on and didn't make a very good showing. Shoe loss was excessive (and I'm being kind). Anybody know what was up with that machine?

at 50% moisture, I don't think anyone's machine was looking great. I've dumped less water out of a can of corn.

I agree I was there but missed the corn harvest we had to take the Monsanto tour which was right in the middle of the combine demo's so we didn't have time before or after. I heard 45-50% moisture on the corn from guys that went. We have trouble with loss in 25-30% corn with a 12 row head on a 8120 which has the same cleaning area as the 9120. They would have to go less than 1 mph to have a chance of having acceptable loss at that moisture and even then I don't know that is wet corn!

I was there and can verify that the corn was wet..the kernels and ear or two I found on the ground were not black layered...several kernels had milk line 3/4ths down the kernel. My estimate was 35-40%. I saw the loss from the 9120 on the first pass..second pass looked much better. Lexion had issues as well on the first pass.

I was at the show tues.crop loss of the 9120 was excessive much worse than any of the other machines. Corn was to wet but most of the other combines were doing ok. I questioned a Case rep. but he had no answers. Hope they got that 9120 saving more crop, it was a embarrassment !

I was at the show on Tuesday and Wednesday and watched the harvest demos both days. The corn was very wet. 35% is extremely conservative. The LEXION did not clog up, its returns plugged up (a very quick resolve - common to any combine in extremely high moisture). The moisture on Tuesday was running in the low to mid 40% and Wednesday was in the mid-upper 30% to low 40% (none of the corn at the show is in black layer yet). The 9120 definitely had some issues running with a 16 row corn head in the tough conditions on Tues. Its grain loss on Tues. was well over 100 kernals per sq. ft. (dropped to about 30-40 on Wed. when they switched to the 12 row corn head). What I noticed to be most significant was the unloading of the lexion 595 vs. the 9120. The 9120 started unloading later into its second pass and finished sooner than the lexion meaning that the lexions grain loss was significantly less - putting more into the tank. The 595 with its 16 row corn head was averaging each pass at about 6-8 kernals per sq. ft. (the 9770 STS with 8 row head the same...with half the head). The corn was about 170-180 bushel per acre. New Holland, Massey and Gleaner (all with 12 row heads) were all around 30-40 kernals per sq. ft. on Tues. New Holland improved significantly on Wed. to the same level as the lexion.

I agree that 35% is extremely conservative. Not all of the combines were emptying the tank when they unloaded. (no comment on unloading time relating to field loss) The corn (that I saw) on the ground behind the 9120 seemed to be in a narrow strip on each side of the shoe. I don't know if it would have been noticeable had the spreaders been running.

Actually we had to combine 42% corn last year for feed for a livestock guy. It was running 170bpa dry with the 8010.. Here ontario we get wet corn .. Wet corn in the midwest ha .. they obviously didn't have round bar concaves in the 9120 and with a 12row corn head 2.2 mph is as fast as you can go without throwing corn out the back. Also running the 15/8th top sieve helps alot. We did plug at first until we got things set up and no problems after that

The cIH website doesnt even list a 16r head for the 9120. Dont really understand how it can be called a true class 1X machine when the only difference is the engine & HP.

i watched the combines run on wed. the gleaner and the lexion had the worst grain loss. I was standing towards the middle of the field. when i went to leave i walked down to the starting point and noticed the grain loss was alot worse at that end. the deere had alot of fine ground corn which surprised me in such high moisture corn.

Certainly high moisture corn is a crop that separates the men from the boys, and it is something that the 8010 has struggled with since day 1, so it is no surprise to me that loss is going to be excessive. If I were still working for CNH, I certainly would not have put a 16 row head on that combine in high moisture corn to show at a farm show! 12 is great plenty and you would want to keep your ground speed within reason. To me, if they don't know their own combine any better than to put it in a situation in which it is going to show poorly, then they deserve it, quite frankly. The Lexion is going to be the best suited to show well in that situation. And while not everyone is going to harvest corn at that moisture, a good combine needs to be able to adapt to it and keep the grain in the tank.

So where is the upper limit? What moisture % would be considered unreasonable?

They should have pulled an FR off the NH lot and chopped that stuff; that's about all it was good for.

Someday the big 3 (4?) need to get together and agree that they're not going to bother wasting their time trying to demo a machine in those kinds of conditions. 90% of the observers could care less how the machine does at 50% (other than it gives them something to razz their neighbors about). They want to know how it performs under typical harvest conditions. Maybe 13 - 30%.
