lift and slide T handles on top of openers Adjust
all press wheels to the same height. T handles
adjust at

inch (6.4 mm) seeding depth change per
minimum handle step. The range is approximately
0 to 3
1 ⁄
2
inch (0-8.9 cm) seeding depth.
• 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 (1.5-3 m) 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
