MAINTENANCE
Seed Meter Adjustment
IMPORTANT
All the Seed Meters MUST BE CLOSED! It may be
necessary to individually adjust Seed Meter Adapter
with Seed Meter attached or Seed Meter if Meter
Adapter is not used.
All Seed Meters must be set the same to ensure seeding
uniformity. To check, set the Seed Rate Adjusting Nut to
0-A. The "A" on the Seed Rate Adjusting Nut is
positioned over the "0" (the nut covers half of the "0") and
snug against the bearing. All Seed Meter Cups should be
closed. If not, there are three adjustments to make as
needed. See Figure 5-7.

1. Hex Nuts with Set Screws on both ends of the
Adjusting Screw are used to adjust all Seed Meters
the same amount. See Figure 5-7. To adjust Seed
Meters to be closed at "0A", loosen Hex Nuts with Set
Screws (remove set screws first) and set adjusting
screw to "0A". Slide Seed Shaft to close all Seed
Meters. Tighten Hex Nuts with Set Screws against
Adjusting Screw and install set screws to lock against
Seed Shaft flats.
2. There are 4 sections of Seed Meters grouped
together per Seed Box. On each end of each section
there are 3/8 Square Bore Collars with Set Screws.
Loosen Collar Set Screws to move that particular
section as needed.

3. Individual Seed Meter Adapters with Seed Meter Cup
attached or Seed Meter Cups (if Meter Adapter is not
used) can be adjusted as required. Adjustments can
be made by loosening the 1/4-20 x 3/4 Machine
Screws that mount the Seed Meter Adapter or Seed
Meter Cup to the Seed Box and the 1/4-20 Nut that
attaches the Seed Meter Support to the Seed Meter
Cup. Adjust the affected Seed Meters so the Feed Cut
Off is against the star washer in the Seed Meter Cup
(closed). Be sure the Meter Feed Roll stays engaged
in the Seed Meter Star Washer. See Figure 5-9. After
adjustments have been made seal the Seed Meter
Adapter to Seed Box with clear Silicone.
