Combines settings for popcorn

First, chrome bars, if worn a little might, I repeat might, be just fine for pcorn. I had rather chance them than a NEW set of black bars. If you do change bars, only change the first two of three rows on the small Pn3 and then leave every other row out. This means you only need 8 bars. The last row will be fine as is or you can remove every other row if it will make you feel better or if you think someone will look in and ask you a question it will take days to answer-). If your combine has those T.P.'s of black metal on top of the cyl. cage- remove them for a 2-3% increase in capacity in all crops. Now start at the header. Narrow the stripper plates to the stalk size and leave the rear open at least an 1_8" wider than front. Either raise the header auger as high as possible ,rare incidence, - or set it down and back as far as possible for white and other corn corn. You either want an entire ear to pass under the auger (only on certain very small varieties) or you want NOTHING to pass below the header auger as in 99% of the fields_varieties. Run header at slow variable speed. Feeder chain in slow position. (special pop corn smooth bars are available for certain pesky, easily scuffed varieties) If you don't have shock kit, install one now. Remove the 'wear strip' on the door. We like the 'hump kit' but it is optional. Remove any filler concave strips. level the grate perfectly per op man then lower front setting one or two marks toward max.(9_16" at front while upper back bar is at 0") Set cyl clearance to the average size cob diameter. Cyl speed at 250 for starters. Extended bars_ cut paddles are great to reduce cob breakup and solve other non-pcorn problems. We remove every other wire in separator grate and leave them out for all our crops. (corn, soft red winter wheat, soybeans and small light grains) Set top seive at 1_2" and chaffer at just over 1_4" or at the largest kernal diam. The slots will give you enuff capacity. Air on 5 or 6. Make sure elevator chain is tight as well as tailings. Make sure clean grain and tailings elevator have enough clearance to let kernals pass between the auger and the auger floor. Same for the bin loader.(special undersize augers are available) leave bin loader in as low position as feasable and don't fill the bin over it unless you have to have the capacity to make it to the rows end. In any case try to dump before it covers the tube end and starts pushing grain up through the auger end. Unload at an idle or just off idle. Don't be afraid to change from these settings but MAKE ONE CHANGE AT A TIME. Remember we have discussed here that about half the damage in white or popcorn come from places other than the cyl. Now for a few extra tricks if needed. Fabricate a set of fairing (spIJ) extentions as the grain tables use to cover the ends of the feeder chain in the header. They will work but need a little bending. The corn hd hopper bottom riser is a real good item to raise the floor closer to the chain. In white corn the 7" drum is a help. Also harvest at maximum rate possible. Corn shelled on corn is the gentlest action one can have. (short of x-lax treatment, but I digress) Any questions ask and ye shall receive as we have to diverge, or divulge or whatever.
