4.9 Checking Air & Product Flow
The test procedure outlined below serves as a guideline for ensuring proper fan
speed for effective delivery of product:
1. Remove hose(s) from an outside opener and temporarily attach to the frame
of the seeder with the hose looping no more than 12 in. (300mm) below the
frame.
2. Begin seeding at normal field speed and observe distance product discharges
from hose(s) attached to the frame.
All product should discharge within a
range of 12-24 in. (300-600mm).
3. Adjust fan speed, if necessary, to ensure optimum air flow for product dis-
charge.
DO NOT set fan speed above 5000 rpm. Excessive fan speed will
damage the fan drive motor and requires more power from the trac-
tor hydraulic system.
