Depth Wheel Scrapers (Option)
Side depth wheel scrapers may be useful in moist or
sticky soils that tend to accumulate on side depth
wheels reducing the intended planting depth.
To adjust depth wheel scrapers:
1. Loosen the nut (1).
2. Slide the depth wheel scraper (2) toward the
depth wheel until the scraper touches the tire.
3. Slide the scraper away from the wheel leaving a
1/8 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
Crushing Hazard
Ensure machine is secure before working on it.
A falling machine can result in severe injury or
death.
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 - factory setting is staggered for
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
Plainer dealer for information.
Down Pressure
To adjust the down pressure:
1. Lower planter into field position.
2. Move the adjustment handle (1).

For less down pressure, move the handle
forward (A) toward the planter.

For more down pressure, move the handle
back (B) away from the planter.
Increased press wheel spring force may
require increased row unit down force to
maintain depth.
Press Wheel Stagger
To change the press wheel stagger:
1. Raise the planter.
2. Remove the bolt (1), spacers (2 and 3), lock
washer (4), and nut (5).
3. Reinstall the spacers, press wheel (6), and
hardware to the other hole location (7).
