1. Drop a pan and quantify the loss to assess and measure grain loss — this provides a benchmark for further adjustments.
2. Perform a power shutdown to distinguish between sieve loss and rotor loss. If uncertain, adjust based on observations, then re-drop the pan to see if the change improved or worsened the loss.
3. Use the yield loss monitor only after calibrating it against your drop-pan results to track real-time losses accurately.

Start with a calibration check — verify the concaves are zeroed and calibrated to the rotor during installation. Then:

• Open the concave — if set too tightly it restricts filling and unloading, increasing loss. Open gradually to improve separation.
• Slow the rotor — a high rotor speed can push material out the back before grain separates. Reducing rotor speed allows more thorough separation.

Ensure sieves are calibrated at the start of harvest, then minimize sieve loss:

• Chaffer & bottom sieves — open incrementally until the sample gets dirty, then close slightly. Always start with the chaffer, then the bottom sieve.
• Wind speed — adjust by crop. In lighter crops, reduce wind to prevent blowing grain out with the MOG. Balanced sieves support lower wind speeds.
