Adjusting the fan speed with the tractor control unit

REQUIREMENTS

  • The seed hoppers are filled

  • The machine is unfolded

NOTE
Depending on the equipment, a pressure gauge, control computer or control terminal shows the air pressure. The specified fan pressures are reference values. Check the grain placement after driving a short distance.
Use of the cyclone separator requires a higher fan speed. If the desired fan pressure is not reached, use a bigger hydraulic motor. For more information, contact your specialist workshop.

Seed

Fan pressure

Beets, rapeseed, sorghum or sunflower

35mbar ±5mbar

Maize, soya or field beans

45mbar ±5mbar

  1. Read the fan pressure from the table
WARNING
Risk of injury due to parts of the fan being flung out
If the fan is operated at excessive speeds, fan parts can break and be flung out.
Make sure that the fan speed does not exceed 5.0001/min.
  1. Depending on the machine equipment:

    Unfold the machine.
  2. To switch on the singling fan:

    Switch on the red 1 tractor control unit.
  3. To warm up the hydraulic oil for optimal regulation of the hydraulic system:

    Run the fan for about 5 minutes at 2.5001/min.
  4. To fill the singling discs with seed grains:

    See ISOBUS software > Working > Filling the singling disc.
  5. To correct the fan pressure:

    Adjust the oil quantity on the tractor control unit.
  6. If the cyclone separator is used:

    Check the fan speed setting.
  7. To monitor the fan:

    refer to Configuring the fan speed monitoring in the ISOBUS operating manual

or

refer to Configuring the fan speed monitoring in the control computer operating manual

or

Read the fan pressure on the pressure gauge.
