Adjusting the fan speed with the PTO shaft

REQUIREMENTS

  • The seed hoppers are filled

  • The fan is switched on

  • The singling discs are filled with seed grains

A sticker on the fan housing marks the permitted tractor PTO shaft speed 1 of the tractor.

Depending on the equipment, the air overpressure is displayed by a pressure gauge or the control terminal. The specified fan pressures are reference values. Check the grain placement after driving a short distance.

NOTE
Use of the cyclone separator requires a higher fan speed.
For more information, contact your specialist workshop.
