Seeding Depth
Seeding depth is controlled by coulter depth in front, and
press-wheel height in back. Seed cannot be placed any
deeper than coulter depth. Before adjusting row units,
make sure coulters are performing as desired.
See “Level Frame Side to Side” on page 19.
See “Level Frame Front to Rear” on page 20.
See “Coulter Frame Height” on page 39.
See “Opener Depth (Press Wheel Height)” on page 48.
Consistent seeding depth relies on appropriate
down-pressure for conditions, and an even distribution of
available force across the drill (weight transfer).
See “Frame Weight” on page 41.
See “Weight Transfer” on page 42.
See “Row Unit Down Pressure” on page 44.
While seeding, remember:
• Raise openers before turning. Never back up or turn
sharply with openers in the ground. Doing so will plug
openers and may damage equipment.
• Be aware of the 5 to 10 foot (1.5 to 3 m) delay needed
for seed to reach openers. If you stop in middle of field,
lift drill and back up 10 feet (3 m) before proceeding.
• Check periodically for plugged openers and hoses.
With fan running and drill raised, hand crank metering
system. Look below each opener for seed or fertilizer.
You can adjust the opener height at which seed metering
beings. See “Implement Lift Switch Adjustment” on
page 38.
For information on opener adjustments, see “10 Series
Row Unit Adjustments” on page 43. For information on
troubleshooting opener problems, see
“Troubleshooting” on page 50.
Fan Speed
This information is repeated from the air cart Operator’s
manual, which has additional guidance.
Equipment Damage Risk:
Always engage the fan with the tractor at a low engine speed.
Engaging the fan when the tractor is at high speed may cause
fan damage.
Do not reverse hydraulic flow with the fan running.
