Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER, and the color Safety Red, indicate an
imminent hazard which, if not avoided, will result in death
or serious injury. This signal word is limited to the most
extreme situations, typically for machine components
that, for functional purposes, cannot be guarded.
WARNING, and the color Safety Orange, indicate a
potential hazard which, if not avoided, could result in
death or serious injury, and includes hazards that are
exposed when guards are removed. It may also be used
to alert against unsafe practices.
CAUTION, and the color Safety Yellow, indicate a
potential hazard which, if not avoided, may result in
minor or moderate injury. It may also be used to alert
against unsafe practices.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 5,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

coulters and double-disk openers. The openers are
mounted on parallel arms. Press wheels follow the
opener disks to firm the seedbed and control seeding
depth.
Intended Usage
This machine is intended for use in minimum- or no-till
applications.

Drill Preparation and Setup
This section will help you prepare your tractor and drill for
use. The drill hitch must be adjusted to match drawbar
height, and the drill control console must be installed in
your tractor.
This section also covers bleeding the drill hydraulics and
making drill frame and box adjustments. As the operator,
you may need to perform these functions after dill repair.
Before operating the drill, check that the hydraulic
systems are free or air, the frame is level, and boxes are
aligned.
Pre-start Checklist
1. Read and understand “Important Safety
Information,” 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
lubricated. Refer to Lubrication, page 47.
4. Check that all safety labels and reflectors are
correctly located and legible. Replace if damaged.
See Safety Decals, page 5.
5. Inflate tires to pressure recommended and tighten
wheel bolts as specified. See Tire Inflation Chart
page 57.
Hitch Height Adjustment
Refer to Figure 3
For proper operation, the drill tongue must run parallel
to the ground in field position. Follow these instructions
to adjust the drill hitch to match your tractor drawbar
height.
1. Check the distance from under the tongue to the
ground as shown in Figure 3. Using the drill jack,
adjust the tongue up or down until the distance is
about 28 inches.
2. Back the tractor drawbar up to the drill hitch.
Determine how much adjustment is needed for the
drill to match drawbar height.
3. Unbolt the hitch from the tongue. Bolt the hitch so
the drill matches drawbar height. Keeping in mind
your drill size, refer to Figure 4 or Figure 5 for the
different ways you can bolt the hitch and the
resulting hitch heights.

4. Hitch the drill to the tractor using a hitch pin at least
one inch in diameter. Install a retaining clip on the
hitch pin to prevent it from working up.
A clevis-style hitch, Great Plains part number
196-136H, is available through your Great Plains
dealer.
When hitching the drill to a different tractor, check for
differences in drawbar heights and re-adjust the drill hitch
accordingly.
Installing Drill Control Consoles
1. Mount the control boxes at a convenient location in
the tractor cab. Connect the 12-foot extension cable
to the pin connector on the back of the control box.
Route the cable to the tractor drawbar area. Secure
the cable to avoid damage.
2. Connect the power cords to a 12-volt power source
on the tractor. The polarity of the power supply is
very important. The red wire must be connected to
the positive (+) battery terminal. The white wire must
be connected to the negative (-) battery terminal.
To help with console and wire harness installation
refer to diagram on page 56.

Bleeding Hydraulic Systems
A hydraulic system with air in the circuit will move in
jerky, uneven motions. If your hydraulics have not been
properly bled or you replace a hydraulic component,
bleed the hydraulics.
Field-Lift Hydraulics
The field-lift system is equipped with four rephasing-type
hydraulic cylinders that require a special procedure for
bleeding air. Read and follow the procedure carefully. Air
in the system will cause uneven seeding across the drill.
Do not loosen hose fittings in order to bleed air from this
system.
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.
This drill has a negative tongue weight when unfolded and
raised. Be certain that the drill is hitched securely to your
tractor drawbar and the hitch safety chain is securely attached
to the drill.
Never allow anyone under the drill when fittings are opened.
Escaping fluid may allow the drill to drop suddenly.
1. Check that the tractor reservoir is filled to the proper
level. It will take 4 gallons to charge the field-lift
cylinders.
2. Put the tractor in park and set the parking brake. If
your tractor does not have these features, block
wheels to prevent tractor from rolling.
3. Raise and support the main frame and outside ends
of boxes just high enough to take the weight off all
four field-lift cylinders.
4. With the drill blocked and supported, unpin both
ends of all four field-lift cylinders. The field-lift
cylinders are located on the wing gauge wheels and
the main-frame transport wheels. Remove and safely
position the cylinders so the rod ends are higher than
the base ends. Check that there is enough room for
the cylinder rods to fully extend without contacting
anything.
To prevent trapped air pockets, the rod end must be higher
than any other part of the cylinder.
5. With the tractor at idle, engage the lift-hydraulics
lever. When the cylinders for both gauge wheels
have completely extended, hold the lever on for one
minute.
6. Retract the cylinder rods. Extend the rods again and
hold the lever on for one more minute. Repeat this
step two more times to completely bleed the system.
7. Retract and reattach the hydraulic cylinders.
8. Recheck the tractor hydraulic reservoir level and add
clean fluid as necessary.
Transport-Lock Hydraulics
The transport-lock cylinders are not rephasing. The two
transport-lock cylinders are on each side of the main
frame above the transport axle pivot tubes. Follow these
steps to properly bleed the transport-lock hydraulics.
1. Check that the tractor reservoir is filled to the proper
level. It will take about one gallon to charge the
transport-lock cylinders.
2. Raise the drill to field position and support the main
frame.
3. Select the locks system on the control console.
Retract the lock cylinders completely.
4. Loosen the connection between the hose and base-
end tee fitting on the left lock cylinder. With the
tractor at idle slowly work the remote lever to feed oil
to the base end of the lock cylinders. Stop when you
see oil coming from around the fitting. Do not attempt
to fully extend the lock cylinders when bleeding the
base ends.
5. With the cylinders completely extended, repeat step
4 for the rod-end fitting.
6. Recheck the tractor reservoir and add clean fluid as
necessary.
7. Retract and extend the lock cylinders several times
to expel most air from the system. The remaining air
will be expelled gradually during day-to-day
operations.
8. Recheck the tractor hydraulic reservoir and add
clean fluid as necessary.
