PL5800 Planter Table of Contents Index Operation
Side gauge wheel scrapers may be useful in moist or
sticky soils that tend to accumulate on gauge wheels
reducing the intended planting depth.
To adjust gauge wheel scraper:
1. Loosen the nut (1).
2. Slide the gauge wheel scraper (2) toward the
gauge wheel until the scraper touches the tire.
3. Slide the scraper away from the wheel leaving a
1/2 inch (3 mm) gap (3).
4. Rotate the scraper left and right around the bolt,
making sure it cannot touch the tire if bumped in
the field. If it can touch the tire, back the scraper
away from the wheel until it cannot.
5. Center the scraper angle on the bolt until the gap
(3) is constant.
6. Tighten the nut (1).

Press Wheel Adjustments
Press wheels are attached to each row unit body.
The press wheels close the seed trench and press
soil over the seed.
To provide consistent seed firming, the press wheels
are free to move downward from the normal
operating position. This system maintains closing/
pressing action even if the row unit arm is lifted when
the disks encounter obstructions.
There are three adjustments on the press wheel
assembly:

Down Pressure . An adjustable spring in the press
wheel mechanism creates the down pressure needed
to close the seed trench. The amount of force needed
will vary with field conditions.

Wheel Stagger . The factory setting is staggered to
achieve the best residue flow.

Centering . Press wheels should be centered over the
seed trench.
If the press wheel adjustments do not provide
satisfactory furrow closing, your conditions may
require alternate press wheels. A variety of press
wheel assemblies are available. See your Great
Plains dealer for information.
Press Wheel Down Pressure
To adjust the press wheels, move the adjustment T-
handle (1).

For less down pressure, move the T-handle forward
(2) toward the planter.

For more down pressure, move the T-handle back
away (3) from the planter.
Increased press wheel spring force may
require increased row unit down force to
maintain depth.
Press Wheel Stagger
Crushing Hazard
Make sure machine is secure before working
on the machine. A falling machine can cause
severe injury or death.
To change the stagger:
1. Raise the planter.
2. Remove the bolt (1), lock washer (2), and
spacers (3).
3. Reinstall the spacers, press wheel (4), and
hardware to the other hole location (5).
