PL5700 Planter Table of Contents Index Operation
At the start of each season, perform a
GROUND
SPEED CALIBRATION
over 400 ft (100 m), as
described in the console manual. When completed
and entered in the console, check the reported
implement speed against the tractor speedometer or
other reference.
Singulated Rate
A furrow check is the most accurate way to verify
seeding is at the desired population. This is done by
planting for a short distance with one or two rows set
to shallow depth and with press wheels tied up so
furrows do not close.
Seeds are counted in the furrow over a specific
distance and the area rate is calculated. Refer to the
Material Rate manual for details.
The console will also be counting during the test.
Compare the results.
If the checked rate varies from the chart rate or
programmed rate, there may be a configuration error
that requires correction. Do not calibrate to correct
unexpected variations in singulated rates.

Height Switch
The height switch informs the console if the planter is
raised or lowered. On all planters, the console only
counts seed when the planter is lowered and the
drive is activated. On hydraulic and electric drive
planters, the height switch also enables or disables
the drive.
When the hydraulic drive planter is raised,
the switch state is ignored during
FILL DISK
and
5 REV TEST
operations.
To adjust the height switch:
1. Lower the planter to the height at which seed
delivery should begin.
2. Loosen the nut (1) on the height switch.
3. Rotate the switch until the spring actuator (2)
touches the cylinder pin (3).
4. Rotate the switch in until it clicks. Tighten the
nuts to secure the bracket.

5000 Series Row Unit
Down-pressure cam (1) - A row unit is mounted on
parallel arms, allowing the row unit to move up and
down while staying horizontal. Springs set by a cam
add an adjustable force to the row weight.
Pressurization air inlet (2) - Pressure-regulated air
enters the meter here and holds seed in the disk
cells. See “ Fan Adjustment ” on page 34.
Seed inlet (3) - Gravity carries the seed into the
meter at the seed inlet gate. For bulk hopper
planters, air carrying the seed is vented at the bottom
of the air release cone. Remove the hose for
inspection. There are no adjustments.
Seed meter (4) - see “
Seed Meter Setup and
Adjustments ” on page 39.
Seed inlet gate (5) - This controls the level of bulk
seed at the disk. There are four operating settings,
plus fully closed for shut-off or storage. See “ Seed
Inlet Gate Adjustment ” on page 40.
Side depth wheel - The T-handle (6) sets the planting
depth by controlling the height of the side depth
wheels relative to the opener disks. See “ Planting
Depth ” on page 48.
Press wheels (7) - The press wheels close the
furrow, pressing the soil over the seed to provide
good seed to soil contact. See “ Press Wheel
Adjustments ” on page 50. A variety of press wheels
are available, some are region-specific. Consult your
Great Plains dealer.
Row cleaner (8) - Optional row cleaners clear trash
from the row, to a depth set by an adjustment on the
arms.
Unit mount coulter (9) - Optional unit mount coulters
cut remaining trash and begin opening the seed
furrow. Working depth is set by row depth and a
mounting hole selection. See “ Check the new
height measurement. ” on page 51.
Opener disks (10) - Row unit double disk openers
create the seedbed furrow with adjustments for angle
and spacing. See “ Row Unit Opener Disks ” on
page 48.
Seed tube with sensor (11) - Requires no
adjustment.
Scrapers (12) - Optional inside scrapers require no
adjustment. For side depth wheel scrapers, see
“ Depth Wheel Scrapers (Option) ” on page 50.
