4.6.10 FERTILIZER/GRANULAR CALIBRATION SCREEN
From the main screen depress the number 8 soft-key and then depress the right arrow soft-key six times
to get the operator to this screen.
In this screen the operator can calibrate the fertilizer and granular functions on the planter. It is
necessary to perform this if the planter is equipped with fertilizer or granular prior to starting planting
because it will ensure that the planter is putting on the correct amount. The operator will first start by
gathering an accurate scale and 5 gallon buckets for the right amount of rows for the planter. First weigh
the buckets on the scale and with a marker write the weight of the bucket on the side you will have to
subtract the weight of the bucket to get an accurate weight. Before the operator fills the planter it is
important that the fertilizer gates be set at the same height. Take a ½ inch steel plate to set the gates for
lower amounts if under 1,000 pounds per acre and a 1 inch steel plate if applying over 1,000 pounds per
acre. Once the fertilizer hopper has fertilizer in it and the buckets have been placed under every row the
operator will be able to begin. With the tractor hydraulics engaged depress the number 2 soft-key to start
the calibration. It will only take a couple of minutes for the computer to do this process since it is done
by only turning the shaft a metered amount of revolutions. Once this is finished weigh the buckets
individually and subtract the weight of the bucket. If all rows weigh the same, the operator will then
enter the amount weighed for only one row by depressing the number 3 soft-key and holding it until it
reads the correct amount. If the buckets do not all weigh the same it will be necessary to adjust the
fertilizer gate until the same amount (use gate 1 as your control) is collected across all the rows by
repeating the steps above. Repeat these steps for the granular calibration also.
