Calibrating Grain Weight

Step Action

1 With the combine stopped, the combine grain tank empty, and a

hauling vehicle empty, set the monitor on a load that does not have

any data. Make sure the load is set on the correct grain.

2 Decide the speed at which you will drive or the swath width you

will use for this load to vary the grain flow rate going through your

combine. Try to keep your speed or swath width as constant as

possible for the entire load.

Example of grain calibration loads (Ld) with varying speed (S)

or swath width (SW):

Ld 1 Ld 2 Ld 3 Ld 4 Ld 5 Ld 6

S (mph)

5.0 4.5 4.0 3.5 3.0 2.5

SW (rows)

6 5 4 3 2 1

3 Harvest grain into the calibration load in the monitor.

NOTE: Harvest 3,000 or more lbs for calibration loads.

4 Unload one or more times into the hauling vehicle, finishing with

the following:

• Combine grain tank again empty

• All the grain from the calibration load on the hauling vehicle

• No grain from any other combine on the hauling vehicle

5 Immediately change to another load that does not have any data.

6 Weigh the grain on the hauling vehicle and record the actual load

weight on a log sheet in the back of this section of the manual.

NOTE: If you are using a weigh wagon to weigh the grain, make

sure the wagon has been calibrated properly.

7 Repeat the above steps and harvest another calibration load. You

can also enter an actual weight and calibrate as you obtain each

actual weight.
