Row-Unit Planting Depth
Refer to Figure 61
Side depth wheels
outside the row-unit disks con-
trol row-unit planting depth. The position of an adjustable
T-handle stop
determines planting depth.
Set planting depth by adjusting handle . To adjust, first
raise row-units slightly, then lift and slide handle on top of
row-units. Adjust all handles to the same setting.
For shallower planting, slide handle forward toward
planter.
For deeper planting, slide handle back away from
planter.
Side Gauge Wheel Adjustments
Refer to Figure 62
The side gauge wheels have two, interrelated adjust-
ments:
• angle of side gauge wheel, and
• distance between side gauge wheels and disks.
Refer to Figure 63
Adjust side-gauge-wheel angle so wheels contact row-
unit disks at the bottom of wheel at 2in planting depth
and gaps open
3 ⁄
8
to 5 ⁄
8
in at top. Check with row-units in
soil so wheels are held up.
At the same time, keep side gauge wheels close to
opener disks so openers do not plug with soil or trash.
However, wheels should be out far enough so disks and
wheels turn freely.
Refer to Figure 64
To adjust side gauge wheels:
1. Raise planter slightly removing weight from side
gauge wheels.
2. Loosen hex-head bolt . Move wheel and arm out
on o-ring bushing.
3. Loosen pivot bolt . Turn hex adjuster so indica-
tor notch is at 5 o’clock to 7 o’clock.
Note: Use this as the starting point for adjustment.
4. Move wheel arm in so side gauge wheel contacts
row unit disk. Tighten hex-head bolt
to clamp arm
around bushing and shank.
