Section 1
Preparation and Setup
This section will help you prepare your tractor and drill for
use. This section also includes instructions for bleeding
the optional marker hydraulics.
Prestart Checklist
1. Read and understand “Important Safety Informa-
tion,” page 1.
2. Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and lubricat-
ed. Refer to Lubrication, “Maintenance and Lubrica-
tion,” page 22.
4. Check that all safety decals and reflectors are correct-
ly located and legible. Replace if damaged. Refer to
Safety Decals, “Important Safety Information,” page
4.
5. Inflate tires to recommended pressure as listed on
Tire Inflation Chart, “Appendix,” page 29. Tighten
wheel bolts as specified on Torque Values Chart, “Ap-
pendix,” page 29.
Tractor Requirements
Your drill is designed and factory set for category III trac-
tors.
Hitching Tractor to the Drill
!
DANGER!
Do not place any body part between the tractor and drill during
hitching.
1. Raise or lower the 3-point links as needed.
2. Install the lower hitch pins.
3. Pin the top link to the drill and adjust so it remains
loose in normal field conditions.
4. Check that all three-point links are securely pinned,
then slowly raise the drill. Watch for cab interference.
5. Unpin the parking stands as shown in Figure 1-1. Ro-
tate the stands up into field position and repin.

Gauge-Wheel Adjustment
Gauge-wheel adjustments affect the operating height of
your drill, and drill height directly affects the working range
of the openers.The drill must be adjusted so your openers
can travel up and down and follow the ground contour.
Before using in the field, adjust your drill so the opener
mount tube runs 18 1/4 inches above ground. You likely
will need to make further adjustments later to compensate
for field conditions. Refer to Gauge-Wheel Adjustments,
“Adjustments,” page 11 for how to make gauge-wheel
adjustments.
Bleeding Marker Hydraulics
If you install or replace part of optional markers, you must
bleed air from the marker hydraulics. Your markers will not
fold properly with air in the hydraulic circuit.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.
1. Be sure tractor hydraulic reservoir if full.
2. With the markers unfolded, crack the hydraulic hose
fittings at the base end of the cylinders. With your trac-
tor at an idle speed, activate your tractor hydraulic
valve until oil seeps out around the hose ends. Re-
tighten the fittings.
3. Repeat step 2 for the hose-end fittings at the rod end
of the cylinders.
4. Fold and unfold the markers slowly to work all the air
out of your marker hydraulics. Use caution when fold-
ing and unfolding the marker for the first time and
check for pinching and kinking of hoses.
