Marker Disk Adjustment
The aggressiveness and mark left by the disk can
be changed by two methods.
Changing disk angle. Refer to Figure 5. To
change angle of cut, loosen two 1/2 inch bolts (1)
and rotate disk assembly. Retighten bolts.
Changing disk tip. To change the tip of the disk,
loosen two 1/2 inch bolts (2) and rotate disk as-
sembly until marker disk is square with the
ground.
Marker Width Adjustment
To change marker width, loosen marker tube u-
bolt (3), see Figure 5. Slide the marker tube in or
out to desired width. Retighten u-bolt.
Seed Lok Lock Up
Optional Seed-Lok firming wheels provide addi-
tional 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.
