Field Operation
1. Perform all checks listed on Pre-Start Checklist on
page 22.
2. Hitch planter to a tractor with sufficient horsepower.
Refer to Tractor Requirements, “Specifications and
Capacities” on page 97, and “Hitching Planter to
Tractor” on page 13.
3. Set and calibrate planting rate per Planting Rate.
See “Seed Rate” on page 31.
4. Load seed hoppers with clean seed. Add 1 teaspoon
of graphite to each seed hopper. Replace hopper
lids.
5. Adjust down pressure on row units to match field
conditions. Set row units to desired planting depth.
See “Row Implement Adjustments” on page 42.
6. Ensure planter is level. See “Leveling Planter” on
page 17.
7. Lower planter, pull forward and begin planting.
8. Always raise planter for field turns. Meters will stop
automatically as you raise your planter.
Raising/Lowering Planter
Refer to Figure 29
Planter raising and lowering relies on four lift
cylinders
. To raise or lower the planter, move the lever
for the Lift circuit.
Crushing Hazard:
Use transport/lift locks when working around a raised planter.
Do not rely on hydraulic pressure alone to keep the planter
raised. The bypass orifices in the re-phasing system will cause
it to slowly lower unless locks are used.
Disengage transport locks before lowering.
Always raise the planter for any reverse/backing.
Always fold markers before raising or lowering.
