Seed Calibration
The calibration test should be done to confirm the required
seed rate to be sown and is done with the drill stationary and
level.
Seed Calibration Procedures
1 Remove the calibration trays from the brackets on the
seedbox. Place the trays on the calibration tray brackets
below the seeders.
2 Push down all the clear plastic seed directers to redirect
the seed into the calibration trays, as in Fig 10/1.
3 Make sure all the shutters are open and set to the
position indicated in the seed chart for the seed being
sown. Refer Page 16.
4 Check the seed chart (Page 16) for hints on whether the
agitator shaft should or should not be connected. If it is
to be disconnected, remove the lynch pin (Fig 11/1).
5 For the test, half fill the box with seed. If this is not
possible make sure the seed is evenly distributed over all
seeders in the box.
6 Now refer to the calibration procedures in the Electric Drive
Operating Manual.
Note The amount of product to be dispensed during
calibration is entered when initiating the calibration
procedure (refer Electric Drive Operating Manual).
Suggested amounts are specified in Table 3, Page 16. The
greater the amount of product dispensed, the more
accurate the process.
7 To check weigh the seed, scales must be setting level
and out of any wind. Scale accuracy must be to at least
two grams.
