PL5800 Planter Table of Contents Index Operation
holds seed in the disk pockets. See “ Fan and
Meter Pressurization ” on page 32.
(5) Seed Inlet (standard). Air carrying the bulk
seed is vented at the bottom of the air release
cone. Gravity then carries the seed into the
meter at the seed inlet gate. Remove the hose
for inspection. There are no adjustments.
(6) Seed Meter (standard with choice of disks).
See “ Seed Meter Setup and Adjustment ” on
page 43.
(7) Seed Inlet Gate (standard). 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 43.
(8) Side Gauge Wheel Depth (standard). The T-
handle sets the planting depth by controlling the
height of the side gauge wheels relative to the
opener disks. See “ Setting Planting Depth ” on
page 40.
(9) Press Wheels (standard with choice of
wheels). The press wheels close the furrow,
pressing the soil over the seed to provide good
seed to soil contact.
(10) Row Cleaner (option). Row cleaners clear
trash from the row, to a depth set by an
adjustment on the arms.
(11) Unit Mount Coulter (option). Coulters cut
remaining trash and begin opening the seed
furrow. Working depth is set by row depth and a
mounting hold selection. See “ Unit Mounted
Coulters ” on page 48.
(12) Opener Disks (standard). Row unit double
disk openers create the seedbed furrow with
adjustments for angle and spacing. See “ Row
Unit Opener Disks ” on page 39.
(13) Seed Tube with Sensor (standard).
Requires no adjustment.
(14) Scrapers (optional). Inside scrapers require
no adjustment. For side gauge wheel scrapers,
see “ Side Gauge Wheel Scraper (Option) ” on
page 41.
(15) Seed Firmers (seed flap, standard, not
shown; Keeton, optional, shown). The seed
firmer minimizes seed bounce and improves soil
contact. It may also deliver fertilizer. See
“ Coulter Row Adjustment ” on page 49.

Row Unit Down Pressure
The ideal amount of down force causes the side
gauge wheels to compress any loose surface soil,
but not press a trench into the subsoil.
To check down force, operate the planter for a short
distance on typical ground (with or without seeding),
and stop. Leave the planter lowered with row units in
the ground.
At several row units, inspect the furrow created by
the opener disks, but before the furrow closing by the
press wheels (A).
Be sure to inspect rows in and out of tire
tracks.
(1) If the side gauge wheels are leaving no
tracks, or light tracks, increase down force.
(2) If the side gauge wheels are compressing
trash and loose soil, and leaving clear tracks at
the top of the subsoil, down force is correct and
needs no adjustment.
(3) If the side gauge wheels are creating a trench
into the subsoil, down force is too high and needs
to be reduced.
