Combines concave filler plates

[kornkurt]

I have found that the secret to getting these pods threshed out is to run a real close cylinder concave clearance. I set the rear to just barely clear and run the front from 3_8 to 1_2". Also if unthreshed beans are going thru the returns to your rethresher, you should put some of the concave strips inside the rethresher so it can do its job. Make sure your fan deflectors are set so that the air is blowing on the front part of your triple cascade shoe. Remember that any thing that goes thru the front of the top sieve goes directly to clean grain, so this should be your first area of concern. I hope these thoughts will help you.

Filler plates can help with this, but only if the beans are above 15% moisture. Once they hit 14%- we seem to have too much trouble with splits and have to reduce our thresh.Standard settings for soybeans (by my standards) are: 5_8 clearance front, 3_16 clearance rear, 550 RPM. Reduce rpm as beans begin to split.Increase to 600 if tough. Tougher than that - go home and put your feet up. If every second wire is removed in the rear two thirds of the concave, you could leave the filler plates in. If the pods in the tank are only sucker pods then separate them by closing the front of the top seive slightly more than the rear section. Ride these suckers to the rethresher, install the channels and hope that it will do it's job for once. The rethresher on these combines is a joke, try and make the best of it. The best solution to your problem would be to overhaul the threshing cylinder and concave during slack time. Balance it,install a modified concave and shim the bars to a perfect circle. If it's ready for this of course.

Forgot to add in earlier reply. Make sure you keep machine full and running at capacity. Too slow a ground speed or small a header can hurt you here. An MF 860 should have no less than a 20' flex. Ran one once for two years with an 18'head, had to drive nearly 7mph to keep machine full depending on crop. Way too fast to do a nice cutting job and prevent header loss.

Thanks for the reply. You are right about the header size. I have a 220 JD..(rockpicker) header on it now. When I could push it hard, the sample in the tank was relatively clean and verry little splittig of beans. However, when that header does what it does best..pickup rocks, not feed evenly pile beans up between the auger and reel, I had to slow down and watch the slugs go thru. I had just put a new loewen concave in it along with corn and soybean bars (100 acres ago). I rearranged the seive configuration a little and I am happy with it so far. I put an Air foil chaffer in the top section, nothing in the middle section. Then I put an air foil extension in the front section on the lower section along with the regular blunt finger seive. The trick is to put a flap across the rear of the top chaffer to where it is about an inch from the top of the lower seive. Without it the air flow goes everywhere but where it is needed. I can actually adjust fan speed now. Before I always had full blast and thought I needed more. I have one silly question to askIJ On the mf floating cutterbars with the hart carter system , If this is such old technology (Has a step to climb) why did it seem to work so wellIJ In all the time that I ran one of those heads I hardly ever put rock in the machine. they stayed out at the cutter bar and would stay there til I got to the end. Tap the brakes it fell off and then keep going. The reel would feed the material right up that small incline and into the auger , no problem. Enough for now. Happy Harvesting

Wondering why one would put a JD header onto a perfectly good massey when you were happy with the way it worked. The problem I find with the hart-carter system is that there are too many parts fastened together. Bolts break or come loose and moving parts wear. Nice that it is adjustable, you can really fine tune it's performance. But it seems to be necessary to use an aftermarket cutting system to improve the cut. The 18' 1859flex we used to run did the most amazing job when it was on our MF850 with 28l26 tires. Interestingly, it also had a 6 bat reel. This helped the feed considerably. Been disapointed by the fact that I've never seen a 9100 series with a six bat reel. Anyways, as soon as we used this header on our MF860 with 30.5-32 tires, our cut deteriorated. Even after rebuilding the cutterbar. We changed the angle of the gaurds to try and maintain the rock resistance to no avail. Picked up a 50 yr old cultivator tooth one afternoon with the cutterbar and missed it. Ended up bending the chopper rotor and throwing it out of balance. The large tires suck with these headers! One question - Does the bottom front airfoil not block the air from reaching the chafferIJ Unfortunately I've never had the pleasure of working with one of these marvels. Not many in my area interested in these mods. Would like to try some modifications to our MF850 at home this winter. Remember, it all starts at the sickle!
