Adjusting the fan speed via PTO shaft

PREREQUISITES

  • The seed hoppers must be filled

  • Fan must be switched on

  • The singling disks must be filled with seed grains

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

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

NOTE
Use of the cyclone separator requires an increased fan speed.
Contact your specialist workshop for more information.
