I was just doing some quick figuring on the bushel output of my 2377 and 2388 with the 6 and 8 row corn heads in 170 bpa corn. Harvesting at 4.8 mph (my ave. mph last fall app.)with the 6 row the 2377 is running at about 1480 BPA and the 2388 with an 8 row would be running at about 1970. Both elevators are set on the slow speed, I have never run high speed, now if both machines are rated for 3000 BPA is that when the elevators are set on the high speed, if so, then what is the elevator capacity on the slow speed which I always use? It has always worked fine on slow speed for all the corn wheat and soybeans I cut, but am I getting close to maxing the elevators with those kind of bushels per acre at 4.5-5 mph on the slow speed?
