Airflow and Fan Settings
1. Hydraulic Fan -connect the hoses in the following order:
First - connect Zero pressure Case Drain 3/8” hose (1/2” BSP Female QR) to hydraulic
reservoir *
Second -connect Motor Return 3/4” hose (3/4” BSP Female QR) to tractor high flow low
pressure return port.
Finally - connect High Pressure Motor Feed 1/2” hose (1/2” BSP Male QR) to tractor
remote.
Disconnect in the reverse order to prevent motor seal damage.
*The tractor hydraulic reservoir or free drain connection must have zero backpressure.
2. A higher fan speed is usually required to correctly deliver high rate or heavier product such as
fertilizer from the front box. The airflow to the rear box is reduced by setting the butterfly valve
to the approriate position as shown in the table. If this is not done the seed delivered to the disc
units from the rear box may well bounce out of the seed slot.
The following table shows box fill combinations, butterfly position and recommended fan speeds
for normal/fine seeds and fertilizer:-
