5.
Engage the clutch for the fertilizer drive. See
page 86.
6.
If not already done, disengage the clutch for main
seed drive (see page 77).
7.
If not already done, adjust the seed/fertilizer divider
for the intended field operations (see page 33).
8.
Place about 50 liters (20kg, 40 lbs, 2 cu.ft, or 1.5bu)
of material in the fertilizer box.
Rotate the latch
and remove the calibration tray
. Empty and clean it. Re-insert it with the opening
facing up.
10. Make sure the calibration bag is empty and clean.
Hang it from the scale, and adjust the knurled disk
on the top of the scale until the scale reads zero (0).
Refer to Figure 96 - The diverter shaft for the fertilizer box is
behind and above the calibration tray.
11. Remove the calibration crank from its storage loca-
tion on the ground drive.
12. Position the square socket of the handle end of the
crank over the calibration shaft index collar for the
fertilizer box. Push in and rotate the shaft counter-
clockwise to set the diverter gates to send material
to the calibration tray.
13. Also use the crank on the seed diverter shaft to close
the gates, so that no seed is mixed with the fertilizer
sample. See page 79.
14. Raise the drill openers and install lift locks.
Refer to Figure 97
15. Position the hex socket end of the calibration crank
on the ground drive contact wheel shaft, and rotate
the shaft counter-clockwise 3 turns. This is to ensure
that the meters are full of material and metering at
the current rate.
16. Remove the calibration tray. Empty it into the main
seed box, and re-insert it (open side up).
17. Rotate crank counter-clockwise. Stop after the first
two turns and check that material is flowing from all
meters. Slowly remove the tray and check for compa-
rable seed piles.
Continue rotating, at an rpm that simulates the
expected application speed (see table on page 74).
Stop periodically. Check that the tray is not over-full.
Stop when the count (from step 4) is reached.
