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.

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.

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.

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.

Preparation for Field Operations
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 “LiftCylinders” 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

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
2 in.
5.08 cm
10548
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.
155-015M-ATable of ContentsIndex2014-01-09
Page 25
Great Plains Manufacturing, Inc.Table of ContentsIndexPreparation and Setup21
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 thedesired 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.

Operating Instructions
This section covers general operating procedures.
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.

Folding the Drill
Equipment Damage Risk:
Do not lower drill while in folded position, certain equipment
damage will occur.
1. Folding is best achieved on level ground with the
tractor transmission in neutral. Be aware of the
clearance required to fold the drill.
2. NEVER allow anyone near the drill during folding
operations.
Refer to Figure 15 and Figure 16
3. When folding the drill, the drill transport stabilizer
frame should line up with the nest on the front of the
main frame,
If they scrape the wing on the tongue, the boxes can
be raised or lowered by adjusting the wing
adjustment turnbuckle.
Refer to Figure 17
4. Apply hydraulic pressure to the raising and lowering
system. Raising the drill may be required to free up
the transport lock pins in the vertical tubes for
removal. Place pins into transport position.
5. Fold boxes using hydraulic cylinders. Do this very
slowly and carefully. Serious damage could occur if
done fast and carelessly.

Lifting and UnFolding the Drill
Lift Cylinders
The lift cylinders may after a period of time get out of
time or phase. The effects of this can be seen when one
side of the drill is running too low or too high because its
lift cylinder is either overextended or not retracted
compared to the other lift cylinders.
To rephase the cylinders, raise the drill completely up
and hold the tractor hydraulic lever on for a few seconds
to give the cylinders time to rephase. This should be
done each time the drill is raised out of the ground.
Momentarily reversing the hydraulic lever immediately
after rephasing to allow the cylinders to retract about
1
⁄2inch will help in maintaining a level drill.
Note: Understand that having the cylinders become
gradually out of time is different than having air
trapped in the system from improper bleeding.
Each condition is corrected differently.
Figure 19
Transport Lock Pin in Field Position

Unfolding the Drill
Crushing Hazard:
This drill has a negative tongue weight when unfolded and
raised. Be certain that the drill is hitched securely to your
tractor drawbar and be certain the hitch safety chain is
securely attached to the drill hitch and tractor before raising
or unfolding the drill!
1. Unfolding the drill is best achieved on level ground
with the tractor transmission in neutral.
2. Be aware of the clearance requirements of the
unfolding drill. Allow plenty of room to unfold and DO
NOT allow anyone in the area of the drill when
unfolding.
Refer to Figure 20
3. Remove pin from pull-bar transport lock.
4. SLOWLY unfold the drill using the hydraulic
cylinders. For the first time, watch to be sure the
hydraulic hoses do not get pinched or kinked.
Serious damage could occur if the drill is unfolded
carelessly.
5. Apply hydraulic pressure to the raising and lowering
system. Lowering the drill may be required to free up
the transport lock pins in the vertical tubes for
removal. Place pins into storage position.

Transporting the Drill
Loss of Control Hazard:
Never tow an implement that weighs more than 150% of the
tractor. Check your numbers. This drill is quite heavy for its
size. Ensure that the towing vehicle is adequate for the task.
Using an inadequate tow vehicle is extremely unsafe, and can
result in loss of control, serious injury and death.
The drill can weigh nearly 23000 pounds (10500 kg),
depending on configuration and material load. The tractor
MUST be rated for the load and must weigh at least 67% of the
load. If the tractor is not rated for at least 23000 lbs, calculate
or obtain a scale weight of the drill. See chart below for
typical configuration weights.
Do not tow if drill exceeds the load rating of the vehicle.
Before transporting check following items
1. Make sure that hitch is securely attached to the draw
bar of the tractor and that the hitch safety chain has
been securely attached.
2. To prevent possible damage in case of hydraulic
failure during transport, ALWAYS insert transport
lock pins when transporting.
3. Check to be sure the pull-bar transport lock pin is in
position.
4. Check to see if you have the required air pressure in
your transport tires for proper inflation see “TireInflation Chart” on page 68.
5. When in transport, use warning lights and safety
hitch chain. Comply with all federal, state and local
laws when traveling on public roads.
6. Be sure that the drill is properly folded. The drill
boxes must be correctly supported in the folded
position. “Folding the Drill” on page 24.
7. Reduce speed of the tractor when transporting over
uneven or rough terrain. Avoid all chuck holes and
washboard areas in roads.
8. Reduce speed of the tractor when transporting over
hills or steep slopes. NEVER exceed 20 miles per
hour.
9. Use "Slow Moving Vehicle" emblem (page 6) for
warning vehicles approaching from the rear.
10. When transporting, remember the drill is wider than
your tractor and extreme care must be taken to allow
for safe clearance.
11. Extra care should be taken when transporting with
seed in the box.

Marker Operations
It is not possible to operate the markers other than during
a field lift or field lower. If the Lift/Lower steps are
followed, one marker alternately folds on one side at each
lift, and the other unfolds at each lower.
Dual Marker Operations
It is possible to deploy markers on both sides. This might
be needed for special field passes, but can also occur
inadvertently if a lift/lower is interrupted.
Two Markers Out
1. Perform a normal field lower/marker deploy (previous
topic).
2. When the lowering stops, with the marker fully
unfolded, briefly reverse the lever to Extend (lift), then
back to Retract (lower).
3. The marker on the opposing side deploys. Hold at
Retract until the marker is fully unfolded.
Folding From Two Markers Out
With two markers out, the next lift operation folds only
one of them (the second one deployed). To fold the other
marker, use either of two techniques:
• Perform a second lower, then a lift, or
• At full fold of the first marker, perform a brief Extend,
then a Retract, to fold the other marker (and continue
frame lift).
Overhead, Crushing and Sharp Object Hazards:
Do not allow anyone to stand under, near or beyond the end of
opener frame during marker operations. There is risk of
serious injury or death for anyone under the frame or in the
path of a marker. Marker arms are heavy, are under
tremendous hydraulic power, and may move suddenly if the
hydraulic system is damaged or needs bleeding. Marker discs
may be sharp.
Acremeter Installation
Refer to Figure 23
The acremeter is factory installed. It is located on the left
end of the left main drive shaft.
If the acremeter has been removed, screw the threaded
end of the meter into the1⁄2-20 tapped hole in the left
end of center main drive shaft.
Tighten the threaded end only enough to prevent it from
working loose from normal vibration. In use, there is no
torque or tension that might tend to unscrew it.
The acremeter counts shaft rotations whenever the shaft
is rotating - normally this is only with the drill unfolded,
the opener sub-frame lowered, and the drill in motion.
The meter is geared to display rotations as acres, when
using factory-specified tires and inflations.
Tally field acres by noting the meter reading prior to, and
after planting. Subtract the starting from the ending
readings.

Acremeter Operation
Refer to Figure 24
The acremeter, located on the drill clutch shaft, counts
shaft rotations whenever the shaft is rotating - this is with
the drill lowered and in motion or during calibration crank
operation. The meter is programmed to display rotations
as acres or hectares, when using all rows,
factory-specified tires and tire inflations.
Unusual conditions and/or non-standard row spacings
can cause the acremeter tally to vary somewhat from
actual acres planted.
Normal Operating Sequence
The acremeter counts rotations during drill calibration
(and if so, can be useful for calibration, although the
meter must be on, or moved to the shaft being cranked).
1. Record the acremeter reading at the start of planting
(and after calibration). The large "12345.6" format
display is the grand total area planted since meter
installation. The smaller number in the lower left
corner is the number of revolutions per acre for
which the meter was factory-programmed. If the
display is blank, see "Dormant Display" below.
2. Lower drill and plant. Acremeter counts shaft
rotations, calculates acres or hectares, and adds to
the running grand total.
3. During planting (drill lowered and moving forward),
the display blanks (goes dormant), but area tally
continues.
4. When raised for turns, obstructions and transport,
the drill’s ground drive wheel, contact wheel or clutch
disengages the drive shaft, and the meter counts no
additional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display
activates after 30 to 60 seconds, and remains visible
for 30 to 45 minutes.
6. At the completion of planting, record the final reading
of the grand total. If the display goes dormant before
you can read it, see "Dormant Display".
7. Subtract the reading at Step 1 from the reading at
Step 6 for the total planted in the present session.

Dormant Display
Refer to Figure 25
To conserve power, the LCD display blanks itself most of
the time. If you need to read the display after if has
"timed out" and gone dormant:
• use the calibration crank to turn the jackshaft once, or
• gently tap or wave a magnet at either of the Great
Plains logo spots on the lower region of the display. Be
careful not to scratch the window.

Normal Operating Sequence
Refer to Figure 26
To display the number of revolutions per acre or hectare
programmed into the meter simply cover the round bump
on the face of the unit (light sensor) with the palm of
your hand and leave it there for at least1⁄2second before
removing it. A screen that shows “rEV ###” will be
displayed. The ### is the number of revolutions that is
programmed into the unit.
1. The acremeter may count rotations during drill
calibration (and if so, can be useful for calibration).
2. Record the acremeter reading at the start of planting
(and after calibration). The large “123456” format
display is the grand total area planted since meter
installation.
3. Lower drill and plant. The acremeter counts shaft
rotations, calculates acres or hectares, and adds to
the running grand total.
4. When raised for turns, obstructions and transport,
the drill’s ground drive wheel, contact wheel or clutch
disengages the drive shaft, and the meter counts no
additional (non-planting) rotations.
5. At the completion of planting, record the final reading
of the grand total.
6. Subtract the reading at Step 2 from the reading at
Step 5 for the total planted in the present session.

Short-Term Parking
1. Choose a location with level firm ground. Do not
unhitch on a steep slope.
2. Fold drill (page 24).
3. Set hydraulic circuits to neutral.
4. Disconnect hydraulic lines. Secure them so that they
do not touch the ground.
5. Disconnect electrical cables, capping where
provisioned.
6. Move jack from storage position to side of tongue.
7. Slightly raise tongue with jack.
8. Unhitch.Restart tractor and pull away from drill.
Long-Term Storage
1. Clean the drill as necessary. Be sure that the seed
boxes, fertilizer box and all feed systems are
completely cleaned out before storing.
2. Lube chain and adjust all roller chains.
3. Lubricate all fittings as indicated in “Maintenanceand Lubrication” on page 55.
4. When storing in transport position, use all locking
devices as described under “Transporting the Drill”
on page 27 and “Operating Instructions” on
page 23.
5. Apply a light coat of grease to all exposed hydraulic
cylinder rods.
6. Seed cup drive sprocket hub should be oiled in its
square bore. Squirt oil on to the square seed cup
shaft and move seed cup adjustment lever back and
forth in order to get the oil back into the square. This
is most important before putting the drill in storage.
7. Always maintain proper pounds of air pressure in
gauge wheel tires and in transport tires see “TireInflation Chart” on page 68.
8. Store the drill inside if possible. Inside storage will
reduce maintenance and make for a longer drill life.

Adjustments
To get full performance from the 2SF24 or 2SF30 drill,
you need an understanding of all component operations,
and many provide adjustments for optimal field results.
Some of these have been covered earlier in this manual.
Even if your planting conditions rarely change, some of
these items need periodic adjustment due to normal
wear.

Planting Depth Adjustments
Press Wheel-Opener Linkage Depth
Adjustment
Refer to Figure 28
Attached to the rear of each these openers is one of
several optional press wheels. The press wheel and its
mechanism provide two important functions:
1. The press wheel closes the furrow and gently
presses the soil over the seed.
To provide consistent seed firming, the press wheel is
free to move downward from its normal operation
position. This system maintains pressing action even if
the opener body is lifted as a result of the opener disks
encountering an obstruction or hard soil.
2. The press wheel rolls on the ground providing depth
control to the opener and seed.To maintain a
consistent planting depth, the relationship between
the bottom of the opener disk-blades and the press
wheel is upwardly fixed. The upward stop is
independently adjustable on each opener. The
position of the adjustable stop determines how deep
the seed will be placed.
To change the height of the press wheel, which
automatically changes the seeding depth of the opener,
simply lift the "T" handle located on top of the opener at
the rear and slide forward or rearward until the seeding
depth is correct as shown in the inset in. A spring loaded
pin holds the "T" handle at your setting to maintain the
proper depth.

Disk Opener Spring Pressure Setting
Refer to Figure 29
Each opener spring can be adjusted for down pressure.
This is useful when penetrating hard soil and for planting
in tractor tire tracks. To adjust the pressure, remove the
"W" clip at the bottom of the spring and place it in a
higher hole in the spring rod for more pressure, and in a
lower hole for less pressure.

Seeding Adjustments
1. Raise outboard ends of drill boxes high enough to lift
the end wheels off the ground. Rotate gauge wheel
to see that seed cups and drive are working properly,
not binding and free from foreign material.
2. To adjust your seeding rate, first you must decide
which sprocket arrangement you need (see seeding
charts on next pages). To change sprockets, remove
nut on the double speed change sprocket and turn
sprocket over. Loosen the idler arm bolt, put chains
on and tighten both bolts. (The lengths of the chains
will need to be adjusted in order to make this
change.)
3. There are many factors which will affect seeding
rates, including seed treatment, weight of seed, size
of seed, surface condition of seed, and tire
configuration, pressure and slippage. Minor
adjustments will probably be needed to compensate
for these factors.
4. The pounds-per-acre in the seed charts are based
on drills having 9.5L X 15 inch implement gauge
wheel tires.
5.The large differences in seed size and treatment can
cause a wide variation in actual seeding rates. The
seed rate charts on the following pages are based on
average size seed. This may differ from the seed you
are using. Use the seed rate chart as a guide. Set
the pounds-per-acre desired at the indicator number
for your row spacing and complete the following
procedure to calibrate the drill for your specific seed.
a. Place several pounds of seed over three of the
seed cups at the outboard end of the drill box.
b. Pull the seed tubes off of these three disk
openers
c. Raise the drill off the ground.
d. Place a container under the three seed tubes to
gather the seed as it is metered.
e. Rotate the drive gauge wheel until one acre has
been tallied on the acremeter. This will be
approximately 225 rotations on a 24 foot drill and
approximately 182 rotations on a 30 foot drill. Be
sure to check the three seed cups to make sure
each cup has plenty of seed coming into it.
f. Weigh the seed which has been metered. Divide
by three. This will give you the ounces/pounds
metered by each seed cup. Multiply by the
number of openers on your drill to arrive at the
total pounds-per-acre your drill would meter at
that setting. If the seeding rate is different than
desired, set your seed cup adjustment lever
accordingly.
6. You may want to repeat the calibration procedure if
the results of your calibration vary greatly from the
suggested setting contained in this manual.
Tire size and field conditions will also affect seeding
rates. Be certain that your drill tires are 9.5L x 15" and
that they have the proper inflation. When drilling, check
the amount of seed you are using by noting acres drilled,
amount of seed added to drill, and level of seed in drill
box. If you suspect that you are drilling more or less than
desired, and you have accurately calibrated the drill to
your seed, you may need to adjust the seeding rate
slightly to compensate for your field conditions.
Note: This drill is equipped with four-position feed cup
door on each feed cup. The highest handle
position is for wheat and other small grain seeds,
the second handle position is for soybean and
other large grain seeds. Should excessive
cracking occur to the large seeds, drop the handle
to the third position. The wide-open position will
allow complete clean out of the feed cup. MAKE
SURE all handles are in the same position before
drilling.
Note: DO NOT open the cup up to the wide-open
position with seed in the box unless complete
clean out is desired.
Repeat procedures (a) through (f) on each drill section.

Main Box Seed Rate Handle
Refer to Figure 30
There are main box seed rate handles for each section of
the drill (2 handles total). Generally, they need to be set
identically, and you need to calibrate only one section.
The seed rate handle controls the percent engagement
of the seed sprocket in each seed cup. The initial setting
of the handle is given by the Seed Rate Chart.
You can temporarily stop seed flow to a drill section by
setting a handle to zero.
To set a handle:
1. Loosen wing nut under handle.
2. Move indicator from current setting to about 10
past the new desired value from calibration or the
Seed Rate Chart, then move it back to the new
desired value.
3. Tighten wing nut.

The handle has three normal operating position detents:
1
(top detent) is for the smallest seeds.
Use it for wheat and similar small seeds.
2
(middle detent) is for larger seeds.
Use it for soybeans and similar larger seeds.

Refer to Figure 32
1. The proper small-seeds sprocket arrangement given
different drive types on the main drill box. Arrange
the sprockets on the small-seeds attachment
according to which drive type you will use on the
main drill box.
Note: For accurate metering on the small seeds
attachment, the main drill box sprockets must be
set to drive type 1, 2 or 2A.
2. Set the seed-rate adjustment handle on the small
seeds attachment as indicated by the charts, “SmallGrass Seed Charts” beginning on page 43.
3. Calibrate the small seeds attachment to your
material by following the steps under “SeedingAdjustments” on page 34.

Fertilizer Meter Rate
Application rates will vary with fertilizer type, density and
particle size. Relative humidity and field conditions can
also affect application rates. The chart on the page 46 is
based on material with a density of 65 pounds per cubic
foot (1.04 kg/L) and average particle size. Initially set the
rate according to the charts, then calibrate the drill to
your material as described below.
If your drill has two boxes, remember to repeat the
following steps for each drill box.
1. Raise the drill with the tractor hydraulics so the drive
wheels are off the ground. Rotate the drive wheels to
see that the metering system is working properly and
free from foreign material.
2. From the chart, find the setting number for your row
spacing and desired application rate. Rotate the gate
adjustment knob to the number obtained from the
chart.
3. Check that your gauge-wheel tires are the correct
size 9.5L x 15 inches and properly inflated. See “TireInflation Chart” on page 68.
4. Record the weight of an empty container large
enough to hold the fertilizer metered for one acre.
5. Place several pounds of fertilizer over three fertilizer
feed cups on the outside end of the drill box. Pull the
fertilizer tubes off of these three openers.
6. Turn the gauge wheels a few turns to fill the feed
cups with material. Continue to turn until fertilizer
drops to the ground from all three tubes.
7. Place a container under the three tubes to gather
metered fertilizer.
8. Turn the gauge wheel until for one acre
(approximately 225 tire rotations on a 24-foot drill
and 182 rotations on a 30-foot drill). Check that the
three feed cups have plenty of fertilizer coming into
them.
9. Weigh the metered material. Subtract the initial
weight of the empty container. Divide by three.
Multiply by the number of openers on your drill to
determine total pounds-per-acre metered. If this
figure is different than desired, reset adjustment
knob accordingly.
Note: You may want to repeat the calibration procedure
if your results vary greatly from the chart.
10. When drilling, check the rate by noting acres drilled,
amount of fertilizer added to drill and level of material
in drill box. If you are applying more or less than
desired, adjust the metering rate slightly to
compensate for field conditions.
Seeding Drive Speeds
Refer to Figure 33
Note: When changing seeding drive speed for faster or
slower seeding, the fertilizer drive sprocket must
also be changed in order for the fertilizer rotor to
maintain consistent speed. The drawings below
illustrate the proper sprocket arrangement when
using both types of seeding drive speeds.

The fertilizer meter rate charts are based on fertilizer with a density of 65 pounds per cubic foot (1.04 kilograms per
liter). If you are applying fertilizer of a different density, use the following table to convert application rate.

Marker Chain
Refer to Figure 37
There are two, interrelated adjustments for the marker
chain. Make these adjustments in the following order.
Lifting Slack. With marker unfolded, back full-threaded
adjustment bolt down until head extends as little as
possible. Slowly fold marker while observing disk. If
marker disk slides across ground more than a foot before
chain and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis.
Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it will
prevent end of marker from dropping into field
depressions, causing skips in your marker line. Correct
this condition by lengthening chain one or two links at
clevis.

Folding Slack. Fold marker. Use full-threaded
adjustment boltto take slack out of chain while marker
is folded. Extend bolt until there is no chain slack. Lock
bolt in this position by tightening nutson either side of

Disk Scraper Adjustments
Sharp Object Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area.
Refer to Figure 39
Disk scrapers are optional. To keep opener disks turning
freely, dirt scrapers are mounted between disks to clean
as disks rotate.
As field conditions vary, scrapers may need to be
adjusted. In damp conditions, lower scrapers. If openers
are not turning freely, raise scrapers. To adjust, loosen
bolt and move scraper as needed.

Seed Firmer Adjustments
Sharp Object Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton® Seed Firmer,
lower the drill until the disks of the row units are resting on the
ground.
Keeton® Seed Firmer Adjustment
The optional Keeton® Seed Firmer is an engineered
polymer shape that slides down the seed trench. It traps
seeds as they exit the seed tube and firms them into the
bottom of the "V".
Refer to Figure 40
The Firmer is provided with a preset tension which is
recommended for using the first year. The tension screw
can be tightened in subsequent years according to your
needs. Firmers should provide just enough tension to
push seeds to the bottom of the trench.

Check gauge wheel size. Proper size is 9.5L x 15.
Seed treatment will affect seeding rate if the chemicals build up in seed cup. Unless cleaned
regularly, this build up can cause breakage of the seed-cup shaft.
Check speed change box setting.
For instructions on calculating seed rate see “Seeding Adjustments” on page 34.
Use slower drive speed and open flutes in seed cup to a wider position.
Position seed-cup handles to a lower notch.
Check tire pressure. For proper inflation see “Tire Inflation Chart” on page 68.
Check end gauge wheel tire size. proper size is 9.5L x 15.

attached to the boxes at exactly the same distance inboard from the inboard edge of the drill
box (90”) and both are exactly the same length.
JIC fittings do not require high torque.
ALWAYS use liquid pipe sealant when adding or replacing pipe thread hydraulic fittings.
Plastic sealant tape can crack fittings and plug hydraulic lines. JIC and O-Ring fittings DO
NOT require sealant. O-ring fittings require a thin coat of oil on the O-Ring.
IMPORTANT: When using sealant on pipe threads, the friction between the threads is
reduced, therefore, be certain not to overtighten causing damage to the cylinders, valves or
fittings.
Check for foreign matter lodged in one or more seed cup sprockets.
Liquid insecticide from seed has dried within the seed cup. Remove the build up by
disassembling each seed cup and scrape the foreign substance from the turning surfaces.
NOTE: Liquid inoculant should be applied with caution and care should be taken to clean the
seeding system after drilling treated seeds.
Lubricate lower rollers of vertical transport tubes located between the transport tires.
Check hydraulic fittings for leaks.
Rephasing cylinders not properly bled. See “Hydraulic Hose Hookup” on page 16. When
raising drill at end of field, the lifting cylinders should be fully extended to ensure that they
are always rephased. If machine is only raised enough to lift openers out of the ground, lift
cylinders may eventually get out of sequence and cause uneven seeding depth.

Maintenance and Lubrication
Maintenance
Proper servicing and maintenance is the key to long
implement life. With careful and systematic inspection,
you can avoid costly maintenance, downtime, and repair.
Always turn off and remove the tractor key before making
any adjustments or performing any maintenance.
Crushing Hazard:
Always have transport locks in place when working on
implement. You may be severely injured or killed by being
crushed under a falling implement.
High Pressure Fluid Hazard:
Check all hydraulic lines and fittings before applying pressure.
Fluid escaping from a very small hole can be almost invisible.
Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin. If
an accident occurs, seek immediate medical assistance from a
physician familiar with this type of injury.
1. After using your drill for several hours, check all bolts
to be sure they are tight.
2. Remove excess slack from chains. Clean and use
chain lube on all roller chains as needed.
3. Maintain proper air pressure in drill tires.
4. Keep disk scrapers properly adjusted.
5. Clean drill on a regular basis. Regular and thorough
cleaning will lengthen equipment life and reduce
maintenance and repair.
6. Lubricate areas listed under “Lubrication andScheduled Maintenance” on page 58.
7. Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Great
Plains dealer.

Appendix B - Assembly and Setup
Before You Start
❑Read and understand the operator’s manual for your
drill. A basic understanding of how the drill works will
aid in the assembly and setup of your drill.
❑Before attempting to assemble the drill use the
following as a check list. Having all the needed parts
and equipment readily at hand will speed up your
assembly task and will make the job as safe as
possible.
❑Check for all major frame components.
❑Check for fasteners and pins that were shipped with
the drill. NOTE: All hardware coming from the factory
has been installed in the location where it will be
used. If a part or fastener is temporarily removed for
assembly reasons, remember where it goes. Keep
the parts separated.
❑If a pin, bolt or other part has been removed and you
are unsure where it is used, use the parts section of
this manual to identify it. Be sure the part gets used
in the correct location.By double checking while you
assemble, you will lessen the chance of using a bolt
incorrectly that may be needed later.
❑Have a forklift or loader along with chains and safety
stands that are sized for the job ready for the
assembly task.
❑Have a tractor with remote hydraulics ready to attach
to the tongue. The tongue must be anchored to a
large enough tractor to overcome the negative
tongue weight that will be present when the boxes
are attached to the frame. The hydraulics will aid in
raising and lowering the drill to align pins and bolts
during assembly.
Crushing Hazard:
Be familiar with the term NEGATIVE TONGUE WEIGHT. Be
aware of the special precautions you should take when
working with an implement that can develop Negative Tongue
Weight.
❑Have a minimum of two people on hand while
assembling the drill.
Refer to Figure 45
1. Read and understand the previous section titled:
BEFORE YOU START.
2. Read “Important Safety Information” on page 1,
before assembling drill.
3. Set the tongue approximately 21 inches off the
1
ground in a horizontal position with stable blocking
for support.
4. Raise the mainframe up, keeping the side
members horizontal. Position the mainframe over
the tongue and lower into position.
1
5. Secure tongue to main frame with six
1X21⁄2inch long bolts, lock washers and nuts.
6. Attach the tongue screw jack in a vertical position
2

and remove blocking so the unit is on the ground.
7. Remove the safety wires from each hydraulic
cylinder rod clevis between the tires.
8. Slide the hydraulic hoses from the mainframe
through the tongue and pull them out at the tractor
end. Attach tractor male couplers to the hydraulic
hoses.
9. Hook tractor up to the tongue and plug hydraulic
connectors into the tractor. With tractor running at an
idle speed charge the drill hydraulic system. (Be sure
tractor has plenty of hydraulic fluid. This system
requires approximately 3.3 gallons.) When the drill
frame is raised for the first time, one lift cylinder will
extend fully before the other one begins to move.
Once the first cylinder is fully extended continue to
hold the tractor valve in the same position for at least
60 seconds after the second lift cylinder has fully
extended. The reason for the unevenness of raising
for the first time is because the drill is equipped with
master and slave rephasing cylinders. Raise and
lower the frame several times to be sure there is no
binding or problems with your lift system. Refer to
“Hitching Tractor to Drill” on page 13, for additional
information.
10. Attach the gauge-wheel turnbuckle to the
gauge-wheel armon each drill and then mount the
wheel and tire.

11. Position the two drill boxes in line, end to end, with
the end chain drive sprockets outboard and
approximately 3 inches between the drill boxes. Drills
on 8 inch row spacing and narrower will have 8 inch
spacing at disks between boxes.
12. Using the tractor, back the drill main frame up to the
center of the two drill boxes. When close, position
the posts on each side of the main frame so the
9
8
face of the post mounting angles are toward the drill
frames. Attach the postto the drill framesusing
eight 5/8 X 31⁄2 X 5 inch long U-bolts, lock
washers and nuts. With the U-bolts left

loose, slide the drill frames inward so that the
lugswelded to the drill frames are up tight against
13

the post angles. Tighten all the nuts on the U-bolts.
13. Attach frame adjustment link from the drill frame
to the pivot post using the clevis pin with hairpin
14
15
cotters. Pin to pin should be approximately
37 inches.
14. Locate drill transport stabilizer frame861⁄2inches
from the outside edge of each box frame see
Figure 45. Using
and nuts, mount stabilizer to box frame. Repeat
19
5
⁄8inch U-bolts, lock washers

for other side.
15. Adjust clevis end of pull barsso that the distance
20
from the center line to center line of pull bar pin holes
is approximately 1341⁄4 inches.
16. Mount pull bars to drill transport stabilizer frames
and tongue slide. With the tongue slide in the
21
16
back position against its stop, adjust pull bar lengths
so boxes are in line with one another and parallel to
the back edge of the mainframe.
17. Extend the main lift cylinder and place the
transport lock pins in the transport position
23
22
through the holes in the mainframe axle side tube.
18. Fold the drill making sure that the tongue slide
21
moves smoothly up the tongue. When drill boxes are
almost folding in, stop and adjust the post-frame
adjustment links on each box so that the tang on
24
each drill transport stabilizer frame lines up with the
nest on the front of the main frame. Fold drill
25
completely closed.
19. With tongue slide forward on the tongue and drill
folded completely, position the pull bar lock pin
21
26
across the top of the tongue slide. Adjust the
transport lock bolt on top and front of tongue up
against lock pin with
27
1
⁄16inch clearance and lock the
jam nut. This pin prevents the drill from unfolding
when in transport. DO NOT LOWER DRILL WHILE
IN FOLDED POSITION.
20. Check to see that all nuts are tightened. See
“Torque Values Chart” on page 67, for torque
specifications.
