Well, here we are at the end of September and the combines are just getting rolling. What a strange year for weather! Since we are finally getting to the field, I thought I would take a moment to remind everyone of some tips and calibration hints to get the best data possible out of your yield monitor.
Make sure you have the right grain type set for the field you are harvesting. Over and over again I see people harvesting soybeans and their monitor is set to corn. This data can’t be saved.
Check to see the monitor is giving you “believeable” readings. Things as simple as incorrect ground speed or too many or too few acres counting are signs of a real problem that needs fixed.
Calibrate in this order: Temperature, Moisture, Weight.
When calibrating moisture, make a new load and calibrate from a small load. This will allow for less averaging and get you better results.
Weight calibrations should not be done with truck loads of grain. Follow these rules: All loads should be around 3000 lbs, each load should be a consistant speed for the whole load, but each load should be a different speed (or flow rate). Run one load at the slowest speed your machine will ever run, then run one at the fastest speed that your machine will run. Finally stagger two more loads between these two extremes, and you will have your 4 calibration loads to get great results.
Calibrations need to be done for each grain type.
Calibrations should be completed each year, even if the monitor was accurate last year.
Follow these guidelines, and you will have one of the best calibrations you have ever seen on your monitor, not to mention avoid frustrations of finding out a problem after it is too late to correct.
