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.
• For more shallow seeding, slide T handles forward
toward implement.
• For deeper seeding, slide T handles backward
away from implement.

• 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 (1.5-3m) delay
needed for seed to reach openers. If you stop in
middle of field, lift implement and back up 10 feet
before proceeding.
• Check periodically for plugged openers and
hoses. With fan running and implement 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 34.
