4.6 CHECKING AIR AND 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 (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.
NOTE: In the case of a single fan configuration used to double-
shoot product, follow the above procedure and adjust the position
of the air damper, 1, FIG. 33, to set an effective air flow for each
product.
IMPORTANT: DO NOT set fan speed above 5000 rev/min. Excessive fan
speed will damage the fan drive motor and requires more power from
the tractor hydraulic system.
