Figure 1.9
The seed drill fan is located on the front wall of the machine and is driven by the tractor’s hydraulic
system.
The amount of air in the feed system is regulated by the fan rotation speed and by a flap in the air hose’s
distributor to the two seed meters.
The rotation speed of the fan is adjusted by the tractor flow valve and displayed on ControlStation.
Set the fan rotation speed and flap position in accordance with the following tables.
Alarms
The alarm in ControlStation warning of too low a rotation speed is best set to 500 rpm below the preset
rotation speed, and the alarm warning of too high a rotation speed to 500 rpm above the preset rotation
speed; see “Programming” under the section “ControlStation” in the Instructions for the Spirit 400C.
