Default kemper head problems

Hi - just wondering about anyone's experiences with kemper small drum 10 row heads, we were very disappointed with the one we had on our FR9090 this season. It did not feed well at all, we are going to be getting a large drum for next year but am curious as to why they still make them if they all perform like the ones we had. The first one would not feed in anything but perfect conditions and the second one the slip clutches would start slipping under normal load, there was no build up underneath. Both heads only had some demo hours on them and nothing appeared to be wore out. We chopped 1 field that was irrigated - 28-30 ton/acre and it worked pretty good but most of the fields were between 15 and 20 ton/acre that caused problems. It appeared to just stop feeding for no reason right before the feed rolls, no slip clutch would go off. Sometimes you could not even reverse it and get it to go in. Our biggest problems occurred when we were in some sorghum that was not down but was leaning, we had to travel at half the speed going against the lean as we could going the other direction. Kemper advertises that they are made for difficult harvest conditions, but I would hardly categorize leaning crop as difficult- more like normal to me. Does the 9090 have more power than that head can feed adequately? any helpful insight would be appreciated.

Just have a quick question. How does the head do in grass. The reason I asked that is the sorghum and low tonage corn might have small stems and impead the feeding. Also looked at the pictures that you just posted and was wandering if the two kemper heads are different. I noticed that the one is all yellow and the other yellow and black? I would also check with your dealer about your clearences with your drum scrapers and just about every clearence that you can check. Sometimes millimeters on a corn header can mean alot!

Can you update us on how your 9090 does compared to the two 870s that you had before. Your picture shows Two 9090's

We never got into much grass, all the fields were pretty clean this year the sprays must have done their job, the stems were actually larger due to the low population that they planted. In the pictures you are correct there are 2 different heads, the one on the right was our machine with the 10 row head, the other one was a demo machine with the new 12 row and wider throat that the dealer brought out for us to try, we had a couple of guys from New Holland there that day also and they checked it over and all they could say was that it shouldn't be doing it but they had no answers. We had one NH "forage specialist" go as far as to tell us that he thought that plugging once and hour was acceptable. As far as the 12 row went it didn't seem much better as it plugged up 3 times I think just while they were there - same issue - it got to the center and just stopped.

As far as the chopper goes we were pretty happy but the head problem kind of jaded us so when some other minor problems emerged they seemed worse than they really were, bottom line was that it ran all year without any major problems except the KP - one of the grease lines broke and a bearing went out - they brought another one out and had it switched in a couple of hours, that's the longest we were down. We were able to get to almost all of our customers on time but we did lose a couple of jobs because of the time lost with the head and having to drive slower than what the machine was capable of - most of the 15 ton acres were run in economy mode because we were not able to use all the power anyway - sorry this got so long just wanted to make sure you had all the important info. Definitely more efficient with one big machine VS. two smaller ones, don't regret that move one bit.

Also forgot to mention that we had an 8 row large drum to try for awhile - much better feeding but had to drive alot faster that we wanted to. hence the other 10 row small drum (they didn't have any large drum 10 rows to try).

I am interested in the story on these machines.
I sure would like to hear of a solid performer. Day in day out.
Length of cut and processing comparison in your opinion as well would be nice.

We demoed the large drum 8 row, and the ten, Both seemed to perform good. The ten row performance was definitely better between the two big drums. Wish we could get the 8 row head with ten row head drums. Less rows of teeth on the ten giving it more room in the pinch points. Especially important in bad conditions.

Joblo - what is your opinion on the feeding of the large drum 10 row NH/JD versus the orbis 750 with the different small drum location - did you notice any difference between the two?

The chopper is back at the dealer for service now so when they get it apart I need to go and inspect the knives and shearbar a little closer but this was the second season on the corn knives and shearbar and I was very impressed at how they seemed to be wearing over the season, most of our customers are beef operations and before we started chopping for them they had never ran a processor so they are not to picky about the length of cut and processing. We set it at about 3/4 inch and tighten the KP up till all kernels are cracked. It was better than the claas' but I know that was because of the head feeding - with the RU's you get more stems in sideways so there are more long fractions, this was almost eliminated except in shorter corn. Fuel economy also seemed to be better than the two claas' as well.

Our areas are so different its hard to compare - how many acres or tons can you do on a set of knives?

The kemper seemed to bulldoze in the very center less. Probably because of the two big drums side by side allowing them to grab stalks a little better. The little outside drums did a lot better than I expected too. Maybe the buldozing is caused by shape in the center of the sheet metal more than anything. If you get the pile to the side where the small drum is on the claas it will normally pull it in.

Knife wear for us. If we get most of a corn season we are doing pretty good. We recently replaced them in the 1000, and they were installed in june before we started. We have run a lot of milo/forage sorghum which for us is almost as abrasive as wheat for us. So that has been pretty good, and is fairly typical for most of our machines.

We were very dissapointed with the 6 row small drum we had on our deere. It wouldnt feed one row, or two rows or even 3 rows sometimes, but it was absoluteley impossible to get it to feed one row, it would all just kind of fall over and lay on the head.

It performance also got very poor at night when the dew would start to set it, the head would start slugging and plugging.

The operators complained that it never did feed the crop smoothly when compared to the Orbis 600 and Krone 6000, they said you would sit in the seat and feel the chopper slug all day long like you were driving across the rows, even though you weren't.

We told the Deere salesman we wanted to try a 678 Big Drum 8 row, he said they were junk because the brakes always go bad and they knock over more corn when opening up. Both were valid points, but at least with the big drum you didnt have to leave corn in the field as it would actually feed it.

But that Unit just got traded in now.
