4. Reset console to reflect new active row pattern.
See console operator manual for more
information.
Seed Pool Slopes
The best seed pool slope results in the most
consistent seeding with minimal skips and doubles.
The illustrations below are found to be the best seed
pool slopes for sample seeds.
Adjust the seed inlet gate if the suggested setting
does not work for your seed.
For medium size and smaller seeds that flow easily,
the slope runs from just above the 8:00 position on
the housing wall, down to one or two seeds deep at
the base of the rear strip brush (1).
For medium size and larger, or heavily treated
smaller seeds that flow less easily, the slope runs at
or slightly above the 8:30 position on the housing
wall, down to three to six seeds deep at the base of
the rear strip brush (1).
Keep the top left/rear end of the pool below the 9:00
position; meter horizontal center
- line.
In general, the seeds at the base of the strip brush
need to be deep enough that no air escapes, and
that just enough seeds are present to begin
populating the cells.

Seed Meter Operation
1. Install disks for your crop/population range
according to the Material Rate manual and the
instructions beginning on page 33 of this manual.
2. Open the gate at the planting rows to the
recommended initial setting from the seed rate
charts.
3. Operate the fan to achieve the suggested air
pressure.
4. With all rows primed, rotate meters one turn to fill
the cells to the edge of the drop brush. Rotate the
drive shaft (top forward) with a 7/8 inch wrench,
or raise and rotate the ground drive wheel (top
forward).
5. Leave the fan running to keep seed in top cells.
6. Install rain covers.
7. Begin planting. Meter operation is automatic from
this point on.

Seed Meter Hydraulic Drive
The hydraulic drive uses a hydraulic motor (1) as the
power source for meter rotation.
The drive requires a separate closed center hydraulic
circuit capable of 4.5 gal/min (17 liters/min). A check
valve (2) at the motor prevents reverse operation in
case the connections are reversed at the tractor or
the circuit lever reversed.
A solenoid valve (3) controls flow to the motor.
A filter (4) in the system requires periodic
maintenance.
Refer to the console manual for more information.
When the planter is raised in normal field operation,
the lift switch causes the console to shut off hydraulic
flow to the motor. Override this shut off and operate
