Setting Materials Rates
Seeding and application rates are independent for all
boxes (changing rates on one does not affect the others).
Rate setting steps, and rate calibration, are different for
each box.
• See “Setting Main Box Seed Rate” in Seed Rate
Manual.
• See “Setting Fertilizer Rate” in Seed Rate Manual.
• See “Small Seeds Rate” in Seed Rate Manual.
All of the boxes use fluted-feed meters. Actual rates
frequently vary from chart rates due to variations in
materials, conditions and application speed. Calibration
is strongly encouraged. It is also wise to monitor material
consumption in the field, both to confirm the calibration,
and to catch any stoppages or other malfunctions.
Calibration is described in the rate setting topics of the
“Adjustments” section.
Note: No meters operate if the lock-out hub is
disengaged. Be sure to re-engage the hub after
transport and calibration.
Initial Seeding Depth
Refer to Figure 13
1.
Set opener seeding depth by adjusting press-wheel
height
. To adjust, first raise openers slightly, then
lift and slide T handles
on top of openers Adjust all
press wheels to the same height. T handles adjust at
1
⁄
4
in (6.4mm) seeding depth change per minimum
handle step.

While seeding, remember:
For information on opener adjustments, see “Row Unit
Adjustments” on page 29. For information on
troubleshooting opener problems,
see “Troubleshooting” on page 34.
• For more shallow seeding, slide T handles
forward
toward implement.
• For deeper seeding, slide T handles backward
away from implement.
• Keep the top of the opener frames level with the
ground for consistent seeding depth.
• Raise openers before turning. Never back up or
turn sharply with openers in the ground. Doing so
will plug openers and may damage equipment.
• Check periodically for plugged openers and
hoses.
