Basic Calibration Procedure (Continued)
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
1Remove the calibration tray from the storage brackets on the seedbox. Place the calibration tray (1) adjacent to the seeder units (Fig 6).
2Position all the clear plastic seed diverters (2) to redirect the seed into the calibration tray (Fig 6).
3Make sure all the shutters are open and set to the position indicated in the seed charts for the particular seed (Table 2. Page 14.
4Check the Sowing Chart ‘Hints’ (Page 14) to see whether to connect or disconnect the agitator shaft by removing the lynch pins (1) during seeding (Fig 7).
5For the test, half fill the box with seed. If this is not possible make sure the seed is evenly distributed within the box.
6For setting method refer to Basic Calibration Procedure (Page 15).
Note For seeds which are not covered in the Sowing Chart (Page 14), use the figures for a seed of comparable size and shape.
7Place the crank handle over the hexagonal drive dog on the gear box and turn clockwise until the seed flows consistently from the seeders (Fig 8). 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.
