Marker Disk Adjustment
The aggressiveness and the mark left by the disc may be
changed by two methods:
Changing disk angle. Refer to Figure 29. To change
angle of cut, loosen two 1/2 inch bolts (1) and rotate
disk assembly. Tighten bolts.
Changing disk tip. To change the tip of the disk,
loosen two 1/2 inch bolts (2) and rotate disk assembly
until marker disk is square with the ground.
Marker Width Adjustment
To change marker width, loosen marker tube U-bolt (3),
see Figure 29. Slide the marker tube in or out to desired
width. Tighten U-bolt.
Seed Lok Lock Up
Refer to Figure 30
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, hook one end of the
chain in the opener-body hole just above the wheel arm
(1). Pull the firming-wheel arm (2) up as high as
possible and wrap the chain around the arm. Hook the
other end of the chain in a link. Leave no slack in the
chain; secure the wheel arm in the highest position.
