Seed Calibration
The calibration test should be done to confirm the required
seed rate and is done with the drill stationary and level.
Seed Calibration Procedures
1 Remove the calibration tray from the storage brackets
on the seedbox. Place the calibration tray (1) on the
support members below the seeders (Fig 5).
2 Position all the clear plastic seed diverters (2) to redirect
the seed into the calibration tray (Fig 5).
3 Make sure all the shutters are open and set to the
position indicated in the seed charts for the particular
seed (Table 1, Page 14).
4 Agitator Shaft - Check the Seed Chart “Hints” (Table 1
Page 14) whether to connect or disconnect the shaft by
removing the lynch pin (1) during seeding (Fig 6).
5 For the test, half fill the box with seed. If this is not
possible make sure the seed is evenly distributed within
the box.
6 For setting method refer to Basic Calibration Procedures
(Page 15).
Note For seeds which are not covered in the Sowing Chart
(Table 1, Page 14), use the figures for a seed of
comparable size and shape.
7 Place the crank handle over the hexagonal drive dog on
the gearbox input shaft and turn clockwise until the seed
flows consistently from the seeders (Fig 7). To ensure
complete filling of the seed unit continue turning the
crank until the calibration tray is approximately half full
then empty into the seedbox. The drill is now ready for
calibration.
8 Turn the crank handle clockwise the required number of
revolutions as detailed in Table 2, Page 17.
Note The calibration is usually done for 1/40th hectare.
For very small seed rates or when using inaccurate
scales (i.e. unable to measure to the nearest gram) the
calculation based on 1/10th hectare should be used.
Scales must be accurate to 2 grams, as any error
will be multiplied by either 10 or 40 and give
inaccurate calibration results.
