aSSsume you have high wire grate w_ 3_4" wire spacing in threshing grate. Make sure this is level and drop the front of the grate two marks toward 'max' . Set the clearance to the diameter of the average cob diameter. Cyl speed at 275. Do you have high wire separator grateIJ If the wires are spaced at 1_2" then pull everyother wire out. Not the easiest job but worth the effort. This gives 1" spacing to let the grain through w_o facing the cob plugging the grate problem. The separator grate can be tightened up only about 1_4"-3_8" tighter than the -0- setting before cob breakup and power consumption hits hard. What we do is to bolt in a retarder system in the bottom of the grate. We are using a cyl bar out of a conventional cyl (because we happen to have some - these are old IH and DEERE rasp bars that we cut the back lip side off) bolted in in about 18" lenghts -two threaded hole lengths - to the separator grate. This shreads the shucks and or removes them from the cob thus dumping the corn rolled up within. We have bolted in as many as four of these to stop the loss. We ususally don't run as many reverse bars as you have, in fact we are now taking out the reverse bars and leaving them out with nothing in place of them. We are bolting in some disruptors, on the cylinder itself. These are made from the paddle backup gussets and in the thresher area shortend to the height of the cyl bar. This seems to help in green stem soybeans mostly. Keep in mind, when you drop the spreader it takes 18 whole kernels of corn per running foot to = 1 bu_a.
