I DON'T THINK THEY MEANT BETWEEN THE CYlINDER AND BEATER. THERE SHOUlD BE CURTAINS BEHIND THE BEATER. DEPENDING ON THE CROP YOU ARE HARVESTING, YOU MAY WANT TO REMOVE THE CONCAVE INSERTS TO GET MORE CROP ON THE SHOE INSTEAD OF THE WAlKERS. ARE YOUR RISERS ON THE WAlKERSIJ I THINK YOU CAN ADD MORE RISERS TO MAKE THE WAlKERS MORE AGGRESSIVE. AlSO SOME COMBINES HAD A 150% BEATER WHICH WOUlD THROW THE CROP FURTHER BACK ON THE WAlKERS. CHECK THAT THE BEATER DRIVE AND DRIVEN PUllEYS ARE THE SAME SIZE FOR THE 100% BEATER DRIVE.

I've heard the hardened rod that is welded to the stripper plate for a wear surface can cause alot of shelling. The cob comes down against the hump from the rod protruding up a bit and it can knock off some kernals. I don't know if you could weld a filler iron up next to rod or grind the hump off on a row and give it a try. I think the Hyper boys told me one time that they have strippers made from stainless steel and do not have any kind of wear rod welded to it to prevent that shelling.

Are you sure that you were walking it out. In our area of North Texas the grain was popping out of the heads before harvest. What caused thisIJ I am not sure but we have a solid stand in all fields now. I walked my fields before harvest and figured at least 10% of the grain had popped out of the heads. Now if you have a green strip right behind the combine that is different. Either slow down or open the screens up more. If you are not getting docked for FM don't worry about a little trash in the bin.

Alot of that grain you see sprouting on the ground you did not want in the tank anyways. If you would look upon closer inspection I think you will see and find that alot of those kernals are the shriveled one's that you simply blew out the back because they had no weight to them. If you were to put them in the tank it would have severely dropped your test weights and harmed your end product. NO combine will keep every kernal no matter how well you try to set it. They will loose some and the book will tell you how much is an acceptable loss for the size of machine you are running with a certain size platform. Even though these kernals were shriveled and lightweight they will still germinate and make green. You could be right.....there might be some simple little adjustments you need to make whether it be the seives or how fast you are driving but without a grain loss monitor you will need to get out consistantly and check till you find a speed that throws the least out the back and even then on hillsides and terraces there's still not much you can do as they all toss it out the back besides a model like a hillside that's made to fix that problem. Good luck on your judgement

All of the comments are appreciated. Additional ones still welcome. I will keep a closer eye when cutting milo. Should do a better job since we will not be ruuning so much straw through it. The milo_corn_beans are looking great. I think all wheat that is left in the field may stay there. Cut a sample last Sat and it had sprouted in the head. At this point everyone is full of sprouted wheat to make feed. I guess we can lay it down and bale it for the mushroom companies. Can not wait to start milo harvest (maybe July 20-25IJ). Have a great weekend.

There is at least one man out there that understands combines. And I sure thank you for your Email solution.

Case man, I've never cut canola but in wheat I try to keep the loss down to one or two kernals per square foot directly behind the combine. like they say, "a kernal of grain always looks biggest behind a combine." And that is especially true to a farmer who is paying a custom harvester. K.A.

From a lost $ standpoint, you can have what looks like a lot of grain behind the machine and it won't amount to much money. However, you really pay for it fighting the volunteer that it causes. We try to keep the amount behind the machine to a tiny level...2 or 3 kernels of wheat per square foot right behind the center of the machine I would guess. I've yet to see a walker machine that can get down that low.

I think the 940 here was set on 30% sensitivity on the sieve pads. Seemed to incicate right. showed very low when running full load but when operator stopped it shot up, which is what it should do. When the combine is adjusted for full load and you run it empty the fan will blow grain out the back. When loaded the MOG produced an air backpressure but when running close to empty there is no output restriction so the full amount of air that can be pushed by the fan at its set speed blows the thinner layer of MOG out the back. I'm not sure if the Jan_2004 software updates fixed the problems with the automatic setting feature but if so you can set up a "headland" setting. When you raise the head above the programmed max stubble hight you can make the combine automatically open the seives further and slow down the fan. Then when you lower the head it will readjust back to your in-field settings.

The 30% setting on the chaffer sensors is usually about right. I like to see a little indication in the funnel when everything is working fine and you are running at about 92% of power. The headland feature is really useful in that a lot of the time we go back and forth instead of around the field so it saves some grain if the machine automatically slows the fan speed as the machine runs empty.

Are you now able to override the auto crop setting and the machine keeps your adjustmentIJ last year yet when operating in auto mode any changes the operator made were readjusted back to the originol preprogrammed setting once the header hight resume was pressed. They said that this was going to get fixed but I never saw anything saying it was in the Jan update which so far was the only one.

Has anyone tried some belting on the bottom sieve at the back to stop the air from escaping.I've heard this helps on the cr970's , when operating the sieve fairly tight.Have not got my combine yet,still about a month away from harvest,sitting at dealers lot.

how do you like the Menuon the CR. it is a pain in the A.... i was just running the 980 for 2 weeks. it is so easy to make changes on your reel and change crop without starting new jobs and what ever.

"starting new jobs" is only needed for use with a yield monitor. Any YM system I have yet seen requires this. As far as header setup once you select the correct header configuration for the crop the 1st time you don't need to change it again. For instance you use a defined crop of "soybeans" and with that you have the header setup as "flex head",also stored is the header width ect. Assuming you use the same head for wheat you set up wheat to use a "rigid head" since the cutterbar will be locked up. From then on when you change crops you just select the crop you will harvest and all of the header settings will still be there from the last time you harvested the crop including the header wieght calibration values. In other words once done the 1st time its just hook up and go.
