Combines 2188 with Stripper head settings

[Farm_Kid2]

Are you using the monitor to determine where the loss is coming fromIJ Where do you have to set the Meter Position Knob to get the needle in the greenIJ

 

[Randy]

I have the seed size knob in between medium dot and small dot and the sensitivity on 6 The faster I go the further to the right the meter goes, but the more wheat it throws over--If I slow down the meter goes to the right but less wheat going over. I done a kill stop and the back grate is 1_2 empty so I think the loss is over the sieves. I have a speciality rotor with Gorden bars over two small wire concave and one large wire concave with all wires installed-- two cover plates--2 slotted grates 1 key stock. Air jet sieve with bean element-air deflector-tried air from 1100-1250 Rotor from 800-1050 My wheat is yielding from 14 to 30 bu. I got tired of fighting this combine so I just slow down to 4 mph in the best wheat. Randy

Your hardware seems fine to me. I assume you have about 12 Gorden bars on the front of the rotor. If I were going to change anything it would be to put in all three keystock grates, but you don't need them for 40 bu wheat. Try this: Rotor speed 1000 rpm, concave clearance very tight, fan at 1100. Set the grain selector knob on the medium setting for wheat. Turn the meter position knob to 5. Set the sensor on "Both" and pull into the crop at a speed that pulls about 50-75 rpm off the motor. Go for atleast 300 yards at a steady speed to let the machine fill up and the grain loss meter to reach a steady position. If the needle is pegged out, use the meter position knob to put it in the middle of the green (Clockwise moves the needle to the right, CCW moves the needle to the left). Note the speed you are running and the engine rpm. Now, try to keep the machine at that same load and switch the sensor to "Chaffer". Give it 300 yards to settle out, then switch it to "Rotor" and let it settle out. This will tell you where your loss is coming from. If the loss is from the sieves, the needle should drop to the left when you are on "rotor", indicating very little rotor loss. It is important to remember that the grain loss sensor reacts pretty slowly. I always give it plenty of time to settle out while the machine operates at a steady load. If you find out the loss is over the chaffer, I would put the sensor on "chaffer" and play with the fan speed to try to bring in down. let us know how that goes, but I probably won't have access to a computer over the weekend. Good luck, Mike

Randy, Did you get a chance to try any new settingsIJ Just curious how things are going. Mike

Mike, I have tried the settings you recommended along with about every thing I can think of. The field I am in now is making between 15-20 bu and testing 54 lbs. I have the rotor on 1030,fan on 1150. The monitor is set with the grain position knob between the medium seed size dot and the small dot and the sensitivity knob 0n 6.5.As long as I don't go over 5.4 mph the meter stays in the green and there is not to much grain on the ground. last year I had the local dealer who has set up a lot of stripper headers on Case combines come out to the field to set my machine along with a shelbourne rep. They spent the whole day and did not help one bit. The next day I set every thing back to the way I had it. One thing that Shelbourne does is change the pinch point to the bottom of the conclave's. If I still have this same combine next year I will put the pinch point back to the Case spec's. I think the problem with running a stripper head is nothing goes out the rotor all MOG (witch is a lot more than everyone thinks)goes on the sieve. I over load the the left side of the machine unless I slow the rotor down to less than 850 and then it does not thresh well. Thus I run a corn screen on the left side of the sieve. I could combine wheat faster and do a near perfect job until I run the stripper header but the land I farm benefits so much with the stripper stubble I will change combines before going back to a direct cut header. Thanks Randy

I agree with you that moving the pinch point might help. I always set it to the factory spec but we are running 1010 headers. It seems reasonable that having the pinch point at the bottom of the concave would overload the left side with a stripper header. Did you get a chance to confirm the bulk of the loss is from the chafferIJ How high can you set the sensitivity when the monitor is only on "rotor"IJ On a positive note, running in the green with the sensitivity at 6.5 should be a pretty small loss rate per acre.

We run a 1480 with a 24 ft (CX72)Shelbourne stripper header in spring wheat with all harvest brand large wire concaves. we NEVER run less than 3 cover plates in wheat or we have problems with uneven loading of the Harvest fixed air foil chaffer. grain loss over the chaffer is almost 0 at speeds of up to 6-1_2 mph. Try another cover plate and put the pinch point at factory specs.
