Most of the grain losses from combine operation can be prevented if the grain is ripe enough when it is cut and if the machine is correctly adjusted. The machine should be adjusted for each field that is cut and adjusted several times each day for changing weather conditions. Good operation of the combine is difficult where there is a large proportion of weeds in the crop, but correct adjustment reduces the trouble. Grain loss may be at the following places: the grain platform (reel or cutter bar), the cylinder, the straw rack, and the cleaning shoe.
