Pivot Lock Tube Adjustment
Refer to Figure 36
To adjust tension on pivot-lock tubes, loosen jam nut
(1) and screw bolt (2) in or out to desired setting and re-
tightening jam nut. When pivot frame is 90 degrees to
tongue, bolt head should be about 2 mm (1/16 inch)
away from stop on pivot frame (3).
Seed-Lok Lock Up
Refer to Figure 37
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 condi-
tions the wheels may accumulate soil.
To lock up firming wheels, hook one end of chain in the
opener-body hole just above the wheel arm (1). Pull
firming-wheel arm (2) up as high as possible and wrap
chain around arm. Hook other end of chain in a link.
Leave no slack in chain; secure wheel arm in its highest
position.
