Taking just a little extra time before harvest to make simple adjustments can significantly increase farm profitability. Proper maintenance is important and will save money and down time during harvest. Start harvesting with all combine settings set according to owner’s manual and in the least aggressive part of the range (slowest rotor speed, widest rotor/concave clearance), then make adjustments one at a time and observe the effect of each change. Take an inventory of pre-harvest losses so you can determine what the harvest losses are. Getting out of the combine to check for crop loss is a must! Combine related loss should be 1 bushel/acres or less if crop is standing well. 2 kernels found in 1 square foot represents 1 bushel/acre yield loss.
