Combines Help with wheat settings for 2188

[Farm_Kid2]

Do you have the grain loss monitorIJ That should help you determine where the loss is coming from. If your return volume is reasonable and the return elevator is not plugging, I would suggest installing a keystock grate in the rear position. Assuming you currently have 3 slotted grates, each keystock grate that you add should reduce your rotor loss substantially because the material will now tumble and release the grain. I'm not sure how much extra load this will put on the shoe, but since we've installed the fan deflector we have no problems with the keystock grates in wheat.

What settings are the vanes that are over the concaves atIJ If you have alot of wheat to cut and it is going thru the rotor good, then I would adjust the vanes so that the crop is in the rotor longer. Are you topping the wheat or running as much straw thru as you canIJ

Vane's are in Mid postion and I am leaving approx 6-8 inch of stubble.

I have seen a lot of post's talking about fan deflector's.What are they and how do they workIJI am new to the whole Case IH operation used to run the silver brand.

Remember all that air you had to float the chaff out the back of the GleanerIJ Well, Red ones don't have it. They direct too much of the air blast upward at the front of the shoe and the lesser air volume at the rear of the shoe lets the trash fall down through the chaffer, which then goes through the grain return. It's a simple fix, just click on this link.

So Farm Kid 2 you think that the Red one's do not direct the air in the right areaIJ Should I not be afraid to use too much airIJ I opened up my chaffer a little more in the front so it's the same as the back,I have not messed much with the seive.The fan speed I bumped up aound 1070,I think the main loss is rotor but I not 100% sure. Thanks, Brian

Well, we really need to know more about your machine. Which Rotor, Standard or SpecialtyIJ Which concaves, large Wire or Small WireIJ Which grates, Slotted or KeystockIJ Do you have a chopperIJ How much return volumeIJ Is the return made up of whitecaps or chaff that has been completely threshedIJ As for the fan, you need all the air you can get so you should run it at max speed. It won't blow any wheat off the rear of the chaffer, the velocity and volume back there is just too low. However, it is possible blow the grain upward so hard at the front of the chaffer that it hits the top of the machine. Some of it may be launched clear out the back, I'm not sure about that. It's really hard to identify exactly where the loss comes from unless you use the monitor. Do you have the factory grain loss monitorIJ Without the fan deflector, I would completely close down the front 10" or so of the chaffer to force more air out the back.

I have the specialty rotor,I put in the small wire concave,keystock grate,I have a chopper but it's set on low and I took out the chopper concave.Not sure what you mean about the return volume,my bin sample is clean just a little foreign matter,and I do have a factory grain loss monitor,not totally sold on it.I had one in my Gleaner R-52 before this but I never had much luck with it. So you would close the front on the chaffer down to direct more air to the backIJ Thanks, Brian

With the Specialty rotor and keystock grates your rotor loss should be minimal in wheat. I was wondering if you had some unthreshed heads getting threshed by the chopper, but I now doubt that is the case. If you get excessive return volume the return elevator will plug and you get a chance to see what's in there. Since you're not having that problem you might leave the door at the bottom of the return elevator open for a ways and see what comes out. This is a good indicator of how well you're getting the heads threshed. I've had good luck with the CIH grain loss monitors. Take the access door off on the left-rear corner of the rotor. Make sure you don't have straw bridged up and around the rotor cage. If you do, email me and I'll send you a picture of a rubber flap that you will need to put on the leftmost auger. Make sure both the rotor sensors and the chaffer sensors are clean and free of straw. Now, put the grain selector knob on the middle-sized "dot" and the sensor on "Both". Adjust the Meter Position knob until the needle is at the top of the green while you have the machine loaded. Now, keep the load the same and switch the sensor to "Rotor" and watch the needle. These monitors are quite damped, so it may take as much as a 1_4 mile for the needle to fully settle out. Repeat the procedure with the knob set to "Chaffer". As you flip back and forth it will be obvious where the loss is the greatest. I suspect you will find the loss is coming from the chaffer. If that is the case, start closing the front of the chaffer and see if the loss goes down. (All this assumes that all 4 lamps flicker at all times when you have the machine full, indicating that the monitor is functioning correctly.) let me know what you find, Mike

You need to tighten the concaves to 2 or less. Slow down the fan, I don't know what some guys are talking about, but you can push the wheat right out the back, wheat is light and small and a blast of air will send it out the back. Run the rotor as fast as you can and as long as no cracked kernels, then you'll be all set. Make sure pads are in good shape and vanes are good and you probably should have cover plates for the first 1 1_2 concaves. You should not have a problem with putting wheat out. Set the top chaffer to about 3_8" and the back slightly and I mean slightly larger and the bottom sieve to 1_4" and check the return to get the proper settings. I strongly believe you have too much air going to her. Tighten the concave, speed the rotor, slow the fan, and check and double check. Good luck.
