I read a story the other day about a Case 9120 compared to a Lexion 595r. It said that each machine harvested 4000-5000 acres of corn and the grain loss from the Case was enough to pay for the entire Lexion combine in two seasons. (They were comparable in beans.) I suspect something was set up wrong on the Case or is this true? I just don't believe it. Anyone had bad experiance with grain loss in corn with a 9120?


Thanks,
Mac

Did anyone go to farm progress? Grain loss from the 9120 was so high they switched from a 16 row to a 12 row and still had high losses. Heck all Deere could run was an 8 row.

9120 Definetly had a lot higher losses in wheat when we went head to head. In fairness to the case we did not really now how to set it and I am presuming the salesman did. The ST rotor makes them very tough to set from what I've heard. I don't know if I would get the ST rotor.

Our neighbors with 8120 with small tubes threw over a lot more grain than anybody else too. Just by how green the fields are.

If you know how to set it you shouldn't have very much loss at all in any crop. I have cut 250 corn at 6.3 mph at 20% moisture and had little loss, and 85 bushel wheat with very little loss at 4.5 mph. 7010 combine.

I have an 8010 and If I am not watching closely I am throwing over a bunch. I had great control of the loss with the 2388. When it was getting tough with the 2388 you knew it because it would tell you with the rumble and excessive power. Which would result in loss.
I think that there is so much power in the 8xxx and 9xxx that a guy is able to just keep on going without the combine slowing down. So that is a down fall. I think that all the crop isn't getting thrashed out and the return thrasher thing is a pile of junk. I do wish they would bring back the return back into the rotor. I think the paddle thrasher overloads the sieves too much on the right side which also casuses me to throw more over.
Love the combine to death except I have to be married to the loss monitor and to be sure to have it set well. Don't worry if your not combing at 7 mph becasue the salesman says it will. Yes it will do it but I want more grain in the bin. With the large crops we have had around here a guy just has to slow down some to do it right. Don't care what color you have. My 2 cents

Bobeagle do you have the small tube rotor? I don't remember 8010's being as bad for throwing over before the small tube rotor came out.

depends on the year. after 06 they all got better. all these machines take more fiddling with. esp the vanes and straight bars. slow the rear vanes and run a couple straight bars none of them will throw corn over. raise the choppers up on the lex and deeres and see whats coming out...

On that many acres, the story is indeed plausible. The 8010/7010/7120/8120/9120 models have struggled with high shoe losses from the start and continue to present day, especially in anything approaching higher moisture corn. If you start to add in some rotor loss as well, your total harvest losses add up pretty quickly. As I understand this comparison, it was done with a 9120 that was equipped with a Small Tube rotor. Not the best rotor for corn. One does have to watch harvest losses quite carefully on these machines as they can be pretty touchy in high capacity corn situations.

We have ran 8010's with the AFX rotor since they came on the market. Grain loss was never a concern. In 2009 went to the 8120 with ST rotor. In wheat, dry edible beans, and sunflowers the ST rotor worked fine. However in corn it was definetly harder to keep grain losses down to what we were used to. Have already informed dealer that our next combine will be equipped with AFX rotor.

yes seem to spend more time looking at monitor at times than anything else would be good idea if most combines worked similar to harvest smart or cruise on deere or whatever u call it when crop got thicker it slowed down and lighter crop it increased speed 1 thing i did find very good is 1 and 2 settings on newholland ,s for going up and down steep hills .clever idea.

I haven't ran it in corn yet but my 8120 did the best job I have ever seen done in wheat this year. First pass set close to the book settings with a few tweaks from a CIH combine spec. had her perfect. Nothing on the ground behind the machine and a great sample in the bin. Cant wait to run her in corn.

Sorry be pretty busy lately. No I have the AFX rotor in mine and it is an 06'. Another farmer I was talking to a few years back at a combine clinic thought the same as me that the 8010 threw a little more over than our old 2388's.
I just grow wheat soys and occasionally flowers. The wheat yield here has been between 70 an 90 bushels the last three years and this year looks to be about the same. Before I got the 8010 and the yields were in the 50 to 60's there was less straw, maybe that has alot to do with it also. I am asking an awful lot of the machine to shove through all that sttraw and move down the field at 5 mph.

Again alot of ponies under the hood and you just don't feel it like a guy did with 2388. I find myself always fidling with the rotor, concave, fan, and sieves. Trying to reduce the loss. It is nothing horrible the loss. 6- 14 kernels in a foot. With the 2388 I would always be in the 4-8 range. Yes I take into consideration the wider header and all.

Again not bashing the combine I do love it. I am just being honest.

Wheat was the crop we were having a tough time setting it as well. It was around 60 bu but like you said lots of straw. Not bashing either but the lexion running right beside it was doing far better. To be honest I really liked everything else about the machine. If we had it for a week or something we may have learned to set it better. It was set by the "combine specialist" who works for the local dealer.
