wheels.
2. Remove 5/8-inch bolt attaching wheel to press-wheel
arm. See Figure 3-15.

Closing Wheel Offset
If the closing wheels are not offset, mount wheels in the
front holes of press-wheel arm.
Closing Disk Option
For proper seed-to-soil contact, the closing disks must
have enough down pressure to close the seed trench with-
out unnecessary soil compaction.
To adjust down pressure on closing disks, ratchet spring
cam to next cam height by turning head of support bolt (1)
clockwise. Refer to Figure 3-16.

Seed-Lok Lock Up
Optional Seed-Lok firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and do
not require adjusting. In some wet and sticky conditions
the wheels may accumulate soil.
To lock up the firming wheels in wet conditions, raise plant-
er. Push lock-up handle (1) on top of row-unit body up into
position shown in Figure 3-17. Push up on firming wheel
(2) until wheel arm latches up.
To unlock firming wheels, turn lock-up handle back to its
90-degree position.

WARNING!
Pinching and crushing hazard. The moving markers could
pinch or crush bystanders. Never allow anyone near the planter
when cycling the markers. Reduce marker folding speed to a
safe speed.
!
WARNING!
Escaping fluid under pressure can have sufficient force to pene-
trate the skin. Check all hydraulic lines and hoses before apply-
ing pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this type of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
