The sensitivity setting on the upper sieve and lower sieve can't be set any higher than 30, regardless of whether it's the original shoe or the 'enhanced' shoe and still keep the loss monitor within range. This would be harvesting 25% corn at 2500 bu_hr. If you reduce the setting you can speed up but I'm not satisfied with losses at the 30 level. I've seen the same thing in the 8010 combine. If you are willing to sacrifice grain tank sample and_or accept higher losses that will increase capacity. With the original shoe, major losses would occur around 3000 bu_hr and with the enhanced shake shoe that limit moved up to around 3500 bu_hr. I always want losses to be one-half of one percent of the yield or less, regardless of the crop.
