It's a common misconception that the settings laid out in the operator's manual will give a producer perfect performance from his or her combine every time.
As Les Hill, ag and bioresources program director with the Prairie Agricultural Machinery Institute (PAMI), tells Grainews machinery editor Scott Garvey in this video, every combine needs to be adjusted for the condition of the specific crop.
Settings might need to be changed two, three or maybe more times per day, Hill says, depending how fussy the farmer may be about his or her grain samples. Start with the known settings, he says, and make minor tweaks as you learn the "idiosyncracies" of your machine.
