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 indicates an imminently hazardous situation
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 indicates a potentially hazardous situation
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 indicates a potentially hazardous situation
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 6,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2014-01-09 Table of Contents Index 155-015M-A
2 2SF24/30 Table of Contents Index Great Plains Manufacturing, Inc.
Wear Protective Equipment
▲ Wear protective clothing and equipment.
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ Because prolonged exposure to loud noise can cause
hearing impairment or hearing loss, wear suitable hearing
protection such as earmuffs or earplugs.
▲ Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This drill requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure at other remotes, and
shutting down tractor before connecting, disconnecting or
inspecting hydraulic lines.
▲ Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ If an accident occurs, seek immediate medical assistance
from a physician familiar with this type of injury.
Use A Safety Chain
▲ Use a safety chain to help control drawn machinery should
it separate from tractor draw-bar.
▲ Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach chain to tractor draw-bar support or specified
anchor location. Allow only enough slack in chain for turns.
▲ Replace chain if any links or end fittings are broken,
stretched or damaged.
▲ Do not use safety chain for towing.

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Negative Tongue Weight
This drill can have positive and negative tongue weight,
and it can change during planting. This poses a serious
hazard during unhitching and it can work the hitch pin
loose during transport. To avoid serious injury or death
due to a rising hitch or road accident.
▲ Always use a leveling hitch pin.
▲ Always use the hitch provided.
▲ Always hitch before connecting hydraulics.
▲ Always lower the openers or fold the drill and install the
jackstand before unhitching.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can create
a hazard when driven on public roads. They are difficult
to see, especially at night.
▲ Use flashing warning lights and turn signals whenever
driving on public roads.
▲ Use lights and devices provided with implement.
Transport Machinery Safely
Maximum transport speed for implement is 20 mph (32
kph), 13 mph (22 kph) in turns. Some rough terrains
require a slower speed. Sudden braking can cause a
towed load to swerve and upset.
▲ Do not exceed 20 mph. Never travel at a speed which does
not allow adequate control of steering and stopping. Reduce
speed if towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of towing vehicle.
▲ Carry reflectors or flags to mark drill in case of breakdown
on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 64.
▲ Do not fold or unfold the drill while the tractor is moving.

NOTICE
LIFT CYLINDERS OPERATING INSTRUCTIONS
This machine is equipped with rephasing master slave lift cylinders which
may after a period of time get out of time or phase. An indication of
this is when one section is running too low or too high because its lift
cylinder is either overextended or overetracted compared to the other lift
cylinders. To rephase the cylinders, raise the implement completely up and
hold the tractor hydraulic lever on for a few seconds giving the cylinders
time to rephase. This should be done each time the machine is raised out
of the ground. Momentarily reversing the hydraulic lever immediately after
rephasing to allow the cylinders to retract about 1/2” will help to maintain
a level implement.

Preparation and Setup
This section helps you prepare your tractor and 2SF24 or
2SF30 Drill for use, and covers tasks that need to be
done seasonally, or when the tractor/drill configuration
changes.
Before using the drill in the field, you must hitch it to a
suitable tractor, inspect systems and level the drill.
Before using the drill for the first time, and periodically
thereafter, certain adjustments and calibrations are
required.
Initial Setup
See “Appendix B - Assembly and Setup” on page 69
for first-time/infrequent setup tasks.
Post-Delivery/Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
• Bleed hydraulic system (page 18).
• De-grease exposed cylinder rods if so protected at last
storage.
Pre-Planting Setup
Complete this checklist before routine setup:
❑ Read and understand “Important Safety
Information” on page 1.
❑ Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑ Check that all grease fittings are in place and
lubricated. See “Lubrication and Scheduled
Maintenance” on page 58.
❑ Check that all safety decals and reflectors are
correctly located and legible. Replace if damaged.
See “Safety Decals” on page 6.
❑ Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 68.

Hitching Tractor to Drill
Crushing Hazard:
Do not stand or place any body part between drill and moving
tractor. You may be severely injured or killed by being crushed
between the tractor and drill. Stop tractor engine and set
parking brake before attaching cables and hoses.
Elevating Mass Hazard: This drill can have both positive and
Negative Tongue Weight and it can change during planting.
This poses a serious hazard during unhitching and it can work
the hitch pin loose during transport. Never unhook from
tractor with boxes unfolded and raised off the ground.
Great Plains 2-Section Folding Drills are engineered to
be used with tractors having a standard drawbar. To
operate your Great Plains Folding Drill in most field
conditions, a tractor of 125 minimum horsepower for
24 foot drills and 150 minimum horsepower for 30 foot
drills should be used.
The tractor will need six remote outlets (three pairs). If
your tractor is equipped with only two pairs of remote
outlets and a marker circuit is required, a marker
sequence valve with double selector is available through
your Great Plains dealer.

Tractor Draw Bar Hook-Up
Refer to Figure 3, Figure 4 and Figure 5
1. The hitch can be used as either a single strap, clevis,
or combination hitch.
Refer to Figure 4
2. When using the combination hitch, remove lower
strap when hooking up to a clevis-type tractor
drawbar. Spacers between the drawbar and hitch
may be added to eliminate some of the movement of
the tongue caused from positive to negative tongue
weight.
Two hitch sizes are available:
• the small hole hitch with or without the hammer strap
(11⁄4 inch maximum pin diameter) and
• the large hole hitch without a hammer strap (up to
11⁄2inch diameter pin). The small-hole hitch is sold as
standard equipment.
The mounting holes in the hitch have been offset so the
hitch can be turned over and bolted on in three different
positions giving you six different hitch heights.
On the clevis-type hitch, always mount the thinner strap
on the bottom. SET HITCH SO TONGUE OF DRILL IS
PARALLEL TO GROUND WHEN DRILL IS IN
PLANTING POSITION. Use tongue jack to level tongue,
then find closest setting of hitch to match your tractor
drawbar height.
3. Attach safety chain on tongue hitch to tractor and
lock hook securely on chain. Adjust chain length to
remove all slack except what is necessary to permit
turning of the drill and tractor.
4. The tongue jack makes it possible to raise or lower
the hitch for tractor unhooking and reconnecting.
Always return jack to its horizontal position on top of
the tongue at the pull bar slide stop.

Most of the procedures described in this section require
the use of a tractor with hydraulic remotes. Before
proceeding with the first time setup, or before making
any adjustments mentioned in this section, make every
effort to obtain and hitch a tractor to the drill.
24foot drill: minimum of 125 horsepower
30foot drill: minimum of 150 horsepower
Be certain that the drill tires have the proper inflation as
listed in the “Tire Inflation Chart” on page 68.
Load seed box with seed. Use clean seed to get the best
results. Always have the drill hitched securely to a tractor
with safety chain connected. Lower the drill before
loading.
This drill can be transported with a full box of grain. It is
best NOT to do this unless necessary because the
increased weight does increase the chances for
problems on the road. DO NOT exceed 20 miles per
hour.
Calibrate each seed box for a proper rate based on the
seed that you are drilling. Calibration information is
located on the inside of your box lid or under "Seeding
Adjustments," page 21. Make sure the seed rate is
adjusted the same across the entire drill.
If your drill comes equipped with an acremeter, it should
be mounted on the left gauge wheel axle on the outboard
side. It will accumulate the total acres drilled with the
drill. In order to find out the acres covered, write down
the beginning reading and subtract it from the ending
reading for the total acres planted.
This drill is offered in different row spacings; therefore,
some of the drill boxes do not have the same number of
seed cups between each internal box divider. The
section with the largest number of cups will tend to empty
sooner.
Make sure that the seed-cup-door adjustment handles
are set the same across the drill.
If you notice excessive cracking on large-grain seeds,
adjust all seed cup door handles to a wider setting.
Machine Damage Risk:
Never back up with openers in the ground. If you do, check all
openers to be sure none are clogged.
After lowering the drill into planting position, observe the
drill from the side. Check to see that the tongue is level to
the ground. If it is not, a hitch height adjustment is
needed. See “Tractor Draw Bar Hook-Up” on page 14.
It is especially important to check for this if the drill has
been hitched to a different tractor.
This drill is not designed to be turned sharply in the field.
ALWAYS lift the drill COMPLETELY out of the ground
when turning at ends of field rows and other short-radius
turns. If the drill is not completely raised, the lift
hydraulics will be out of sequence. Refer to “Lift
Cylinders” on page 26.
Crushing Hazard:
Never allow anyone to ride on the drill.
Maximum seeding speed will vary according to soil
conditions.
You can adjust the tension on each disk spring. This is
especially useful in applying more pressure in tractor tire
tracks.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work with system hydraulics.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. If an accident
occurs, seek immediate medical assistance from a physician
familiar with this type of injury.
Use paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.
For ease of operation, your tractor should be equipped
with six remote hydraulic outlets (three pairs). This will
allow you to connect one pair to the drill lift circuit, one
pair to your drill fold circuit and one pair remaining for
connection of optional markers. If your tractor has only
four remote outlets (two pairs) and a marker circuit is
required, a marker sequences valve with double selector
is available through your GREAT PLAINS DEALER.
Refer to Figure 6
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.

Bleeding The Hydraulic Systems
1. If required, raise your drill 1 inch in order to extend
your lift cylinders a little. Loosen the jam nuts on top
Equipment Damage Risk:
The SAE O-RING and JIC 37˚ FLARE type hose connections
DO NOT require sealant for reconnecting. They DO NOT
require high torque for a good seal.
When using sealant on pipe threads the friction between the
threads is reduced; therefore, be certain not to over tighten,
causing damage to a valve, cylinder port or fitting.
Elevating Mass Hazard:
This drill has a Negative Tongue Weight when unfolded and
raised. Be certain that the drill is hitched securely to your
tractor draw bar and be certain the hitch safety chain is
securely attached to the drill hitch and tractor before raising
or unfolding the drill!
Bleeding the Lifting Hydraulic System
This 2SF24/30 is equipped with rephasing type hydraulic
lift cylinders that require a special procedure for bleeding
air from the hydraulic system. If your dealer has not
already prepared the cylinders for transport use, read the
following information carefully. The rephasing cylinders
will not function properly if this bleeding procedure is not
followed.
Note: DO NOT crack hose fittings in order to bleed air
from this system.
Equipment Damage Risk:
Check the hydraulic fluid level in the tractor reservoir and fill
to the proper level before starting this procedure. If the
bleeding is performed with a low reservoir supply, there is a
chance of drawing air into the system. System capacity is
approximately 3.3 gallons and requires one pair of remote
outlets.
of the transport vertical tubes and screw the
adjustment screw in until it bottoms. Lower the drill
until the cylinders become loose.
2. Unpin the cylinders from the mainframe and turn the
cylinders upside down to a position where the rod
end is higher than the base end. Support the
cylinders in a safe location. One transport tire may
have to be removed in order to unpin the master
cylinder.
3. Start the tractor and run the engine at idle. With the
rod end of the cylinders higher than the base end,
hydraulically extend the cylinders and hold the
tractor control lever in position for sixty seconds after
the cylinders have extended to their maximum
stroke.
4. Hydraulically retract the cylinders, then repeat the
extending procedure several more times until both
cylinders are free of air and operate together.
5. Repin the cylinders to the main frame and axle with
the rod end down. If air is tapped in either cylinder,
the affected cylinder will have a spongy, erratic
movement and the machine will not raise evenly.
Refill the tractor hydraulic fluid reservoir to its proper
level.
Note: After drill is raised, a slight settling will occur due
to the action of the rephasing cylinder.
Note: In order to prevent trapped air pockets, the port on
the rod end must be higher than any other port of
the cylinder during the bleeding operation.
Note: The folding and transport/wing lift cylinders are not
rephasing type cylinders and do not require this
bleeding procedure.

Bleeding Folding Hydraulics
The following section describes a bleeding procedure
that requires you to crack (loosen) a hydraulic fitting. Be
aware that these lines may be under pressure even with
the tractor shut off. Never allow anyone under the drill
when fittings are opened. Escaping fluid may allow the
drill to suddenly drop. Be aware of the following medical
alert.
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient force to
penetrate the skin. Check all hydraulic lines and hoses before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor familiar with this kind of injury.
Note: The drill transport lift systems should be
completely operational BEFORE attempting to
work with the folding hydraulic circuit.
Note: The cylinders are double acting but are not the
rephasing type.
1. The first step in charging the fold hydraulic circuit is
to make sure the tractor hydraulic fluid reservoir is
filled to the proper level. System capacity is
approximately 2 gallons and requires one pair of
remote outlets. If optional selector is used, rotate to
the wing lift position.
2. With the drill fully raised and in the folded position,
disconnect the rod end pin on each fold cylinder and
block the cylinders in a location where they are free
to extend and retract without contacting anything.
3. Cycle the fold cylinders in and out several times to
work the air out of the system.
Note: If the wing fold cylinders do not operate properly,
clean out the small hole in the elbow fitting on fold
cylinders. These orifice are located in the cylinder
elbow as circled in Figure 8.
4. Retract the hydraulic cylinder and repin the rod ends.
5. Recheck the tractor reservoir level and add clean
fluid as necessary.
6. It is advisable to fold and unfold the drill several
times. The majority of the air should now be expelled
from this system. The remaining air will gradually be
pushed to the tractor during day to day operations.

Leveling Drill
This section describes procedures for leveling the drill on
its initial setup. This should be a one-time adjustment
and will not be needed during day-to-day operation.
If while using the drill, it appears to be lifting or planting
unevenly, check the following before re-leveling the drill.
• First, make sure the tongue is running level to the
ground while running in the field. Be sure to check this
if the drill has been switched to a different tractor.
• Second, check the lift cylinders. Be sure they are
properly bled, are operating correctly, and do not have
internal oil leaks before using this section to re-level
the drill.
The opener spring rods located along the back of the drill
boxes are indicators of the level of the drill because they
show the amount of down-pressure exerted on the disk
openers and press wheels. A level drill will have equal
opener down-pressure from end to end.
Check the spring rod cross bolts at the top of the spring
rods to see that they are all extended about 2 inches
above their spring rod castings. This is a general
dimension and may vary with the spring down-pressure
you require for different soil conditions and planting
depths, see “Planting Depth Adjustments” on page 33.
If you require more downward float of your openers you
may want to increase this dimension. Keep in mind when
this dimension is increased your upward motion is
decreased, limiting the vertical travel of the openers for
running over rocks and other foreign objects.
Figure 9
Opener Spring Rods

Opener Damage Hazard:
If your openers’ vertical travel is decreased, considerable
damage will occur to your openers.
If all the spring rods along the drill extend the same
distance above their castings, the drill is level and you
should tighten down the threaded studs as described in
“Transport Wheel Adjustments for Leveling Drill” on
page 21. If the spring-rod extensions vary in length, the
drill can be leveled with transport wheel and gauge
wheel adjustments. These are described on page 21.
To summarize: After leveling your drill, it should have the
same dimension from the ground to the box frame at
both ends of each box. These adjustments may have to
be fine tuned after observing the drill in the field in actual
planting conditions.

Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 21
Transport Wheel Adjustments for Leveling Drill
Refer to Figure 10
When leveling your drill, opener spring rods near the
center of the drill that extend higher above their spring
rod castings than desired can be adjusted by raising the
transport frame. This is done by raising the drill with the
hydraulic lift cylinders.
Spring rods near the center that do not extend high
enough are adjusted by lowering the transport frame by
retracting the cylinders. Once the spring rods are at the
desired setting, screw the threaded studs on top of the
vertical tubes (page 22 Figure 13) down as far as
possible and secure them with the jam nuts. This
adjustment will stop the lift cylinder travel at the same
point each time the boxes are lowered for drilling and
assures accurate seed depth control.
Note: If it is noticed that one drill box spring rod
extension is different from the other drill box at the
center of your drill, this is a sign that your lift
hydraulic master and slave cylinders are out of
sequence with one another.
In order to get them back in sequence, simply
raise your drill all the way up and hold your tractor
hydraulic control valve lever on for a few seconds.
Lower your drill and both cylinders will be in
sequence with one another and the two drill boxes
should be at the same level again.
Figure 10
Wing Fold Hydraulics
Gauge Wheel Adjustments for Leveling Drill
Refer to Figure 10 and Figure 11
The openers near the outside of the drill are adjusted by
raising or lowering the gauge wheels.
Raise the drill out of the ground and loosen the jam nut
located near the bottom clevis of the gauge wheel
turnbuckle. This turnbuckle is threaded to allow easy
gauge wheel adjustment. By lengthening the turnbuckle
the gauge wheel is lowered, causing less spring rod
extension through the spring rod casting. By shortening
the turnbuckle the gauge wheel is raised, causing less
spring rod to protrude through the spring rod casting.
After adjusting, be sure the turnbuckle on both gauge
wheel arms have the same pin center dimension.
Shortening the gauge wheel turnbuckle will level the
ends of the drill with the center.

Box Alignment Adjustments
Pull Bar Adjustments
Refer to Figure 12
With the drill lowered to the ground and completely
unfolded the tongue slide on the tongue should be back
against the stop on the tongue. Adjust the pull bars
length so drill boxes are in line with one another and
parallel to the back edge of the main frame.
Drill Adjustments
Refer to Figure 13
Put the transport pins in storage position. Slowly lower
the drill until it is on the ground and the main frame top
slide cylinder is fully extended. Pull the drill forward a few
feet to make sure that the transport and the gauge wheel
tires have equally firm contact with the soil.
Refer to Figure 14
Unfold the drill on a level seedbed typical to your soil
conditions.
At the top of both vertical tubes on the transport frame is
a threaded stud and jam nut. Make sure both studs have
approximately the same length of threads extending
above the jam nut (approximately 3 inches for most
planting conditions). Adjustments may be required.

Experience, machine familiarity, and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
Pre-Start Checklist
Perform the following steps before transporting the two
section folding drill to the field.
❑ Carefully read “Important Safety Information” on
page 1.
❑ Fertilizer Option: Review the application instructions
and Material Safety Data Sheet (MSDS) for the
fertilizer(s).
❑ Lubricate drill as indicated under “Lubrication and
Scheduled Maintenance” on page 58.
❑ Check all tires for proper inflation. See “Tire
Inflation Chart” on page 68.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 67.
❑ Check drill for worn or damaged parts. Repair or
replace parts before going to the field.
❑ Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.
High Pressure Fluid Hazard:
Relieve pressure and shut down tractor before connecting,
disconnecting or checking 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. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
NOTICE
LIFT CYLINDERS OPERATING INSTRUCTIONS
This machine is equipped with rephasing master slave lift cylinders which
may after a period of time get out of time or phase. An indication of
this is when one section is running too low or too high because its lift
cylinder is either overextended or overetracted compared to the other lift
cylinders. To rephase the cylinders, raise the implement completely up and
hold the tractor hydraulic lever on for a few seconds giving the cylinders
time to rephase. This should be done each time the machine is raised out
of the ground. Momentarily reversing the hydraulic lever immediately after
rephasing to allow the cylinders to retract about 1/2” will help to maintain
a level implement.
