
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(300mm)belowtheframe.

2. Begin seeding at normal field speed and observe distance product discharges from
hose(s)attachedtotheframe.

NOTE:Allproductshoulddischargewithinarangeof12‐24in(300‐600mm).

3. Adjustfanspeed,ifnecessary,toensureoptimumairflowforproductdischarge.
