Section 2
Operation
Basic Planting Operation
For the best planting results:
• plant at 5 mph,
• maintain tire pressure in the gauge tires and
• replace worn meter parts.
Rephasing the Hydraulic System
The hydraulic lift system on your Great Plains pull-type
planter is a master-and-slave system. All cylinders in the
system are two way. Each time the planter is lowered into
planting position, the system is rephased.
If unlevel lifting occurs, lower the planter to the ground and
hold the remote lever momentarily.
If following this procedure does not level planter lifting, re-
fer to “Section 5 Maintenance and Lubrication” on
page
35.
Seed Meter and Hopper Operation
This planter is equipped with a 12-finger mechanical corn
meter.
To disengage the seed-meter or chemical-hopper clutch,
pull the knob and rotate 90 degrees clockwise or counter-
clockwise until the roll pin aligns with the notch in the end
of the drive hub. Release knob. See Figure 2-1.
To engage, pull and rotate the knob until the shaft aligns
with the drive hub, then release.

To extend the life and maximize efficiency of the finger
pickup meter, sprinkle 1 teaspoon of powdered graphite
on top of the seeds in the hopper. The graphite will work its
way down to lubricate the meter mechanism.
For more information on the seed meter, see also Planting
Rates, “Adjustments,” page 15, “Section 4 Trouble-
shooting” on page
32 and “Section 5 Maintenance and
Lubrication” on page 35.
The row unit is equipped with a 2-bushel seed hopper.
Before filling the seed hopper, clear it of foreign objects. To
remove the hopper, disengage the meter drive clutch and
the hopper latch. See Figure 2-2.

After filling the hopper with clean seeds always replace the
hopper lid. Operating with the lids attached prevents ob-
jects from entering the hopper and also aids in keeping out
moisture.
Empty the contents of the hopper periodically to avoid the
collection of dirt and other materials.
