A.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. Know the reporting
requirement for spills or releases of the chemicals you are
using. Have contact numbers available.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 5, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
04/28/2014 564-070M
2 FH6000HD Great Plains Manufacturing, Inc.
Use Safety Chains
▲ Use safety chains to help control drawn machinery should it
separate from tractor draw-bar or trailing nurse tank hitch.
▲ Use chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach implement 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.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This flex harrow requires a PowerBeyond 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.
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 driv-
ing on public roads.
▲ Use lights and devices provided with implement.
564-070M 04/28/2014
Great Plains Manufacturing, Inc. A.Important Safety Information 3
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 tow an implement or nurse tank that weighs more
than 1.5 times the weight of towing vehicle.
▲ Carry reflectors or flags to mark flex harrow 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 32.
▲ 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.
▲ Reduce speed on rough roads.
▲ Comply with national, regional and local laws.
▲ Do not fold or unfold the flex harrow while the tractor is
moving.
Shutdown and Storage
▲ Lower flex harrow, put tractor in park, turn off engine, and
remove the key.
▲ Secure flex harrow using parking jack provided.
▲ Detach and store flex harrow in an area where children nor-
mally do not play.
Tire Safety
Tire changing can be dangerous. Employ trained personnel using correct tools and equipment.
▲ When inflating tires, use a clip-on chuck and extension hose
long enough for you to stand to one side–not in front of or
over tire assembly. Use a safety cage if available.
▲ When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.

Preparation and Setup
This section helps you prepare your tractor and
FH6000HD Flex Harrow for use, and covers tasks that
need to be done seasonally, or when the tractor/flex harrow configuration changes.
Before using the harrow in the field, you must hitch it to a
suitable tractor or leading implement, inspect systems
and unfold the harrow. Before using the flex harrow for
the first time, and periodically thereafter, certain adjustments may be required.
Initial Setup
See “Appendix B - Initial Setup” on page 35 for firsttime/infrequent setup tasks, including:
• Hitch Configuration (page 35).
• Tooth Angle (page 37).
• Install wing extensions (page 39).
• Install 4 bar drag extensions (page 40).
Post-Delivery/Seasonal Setup
On initial delivery, and seasonally, check and as necessary, complete these items before continuing to the routine setup items:
• Bleed hydraulic system (page 28).
• De-grease exposed cylinder rods if so protected at last
storage.
Pre-Application Setup
Complete this checklist before routine setup:
❑ Read and understand “A.Important Safety Informa-
tion” 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 lubri-
cated. See “Lubrication and Scheduled Mainte-
nance” on page 29.
❑ Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals” on page 5.

Great Plains Manufacturing, Inc. Preparation and Setup 13
Hitching Harrow to Tractor
Hitch to a tractor for highway transport or field operations. Hitch to a leading implement only for field operations. Do not transport behind another implement.
Before hitching, check the compatibility and capability of
the towing tractor or implement:
• The flex harrow is a pull-type implement equipped with
a standard Category IV single tang hitch. It may be
converted to a Category III or clevis hitch using supplied accessory parts (see “Hitch Configuration” on
page 35).
• Tongue weight varies from 500 pounds to 2300
pounds, depending on harrow model. See “Specifica-
tions and Capacities”, pages 32 to 33.
• Recommended tractor horsepower is 3 hp per foot of
implement width (72 to 162 hp, depending on harrow
model). This is in addition to the power required for
any leading implement.
• A leading implement must pass through one hydraulic
circuit.
Refer to Figure 3
1. Use jack to raise and lower harrow tongue.
2. Back tractor draw bar into alignment with hitch.
3. Secure with a locking hitch pin .

2
Crushing Hazard:
Do not stand or place any body part between harrow and moving tractor. You may be severely injured or killed by being
crushed between the tractor and harrow. Stop tractor engine
and set parking brake before attaching cables and hoses.
2
Negative Tongue Weight Hazard:
Make certain that harrow is securely hitched to the tractor or
leading implement before unfolding. An unhitched harrow can
tip over backwards during folding and unfolding if the tongue
is not secured.
4. Secure safety chain to an anchor on the tractor.
5. Retract jack foot. Re-orient jack to storage position.
6. After hitching tractor to harrow, store jack on storage
stob on flex harrow tongue.

Electrical Hookup
Refer to Figure 4
Your flex harrow is equipped with lights.
Plug the lighting connector into the tractor outlet.
Test the lights and signalling prior to highway movement.
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.
Refer to Figure 5
To distinguish hoses on the same hydraulic circuit, refer
to hose label.
• The hose with an extended-cylinder symbol feeds a
cylinder base end.
• The hose with a retracted-cylinder symbol feeds a cylinder rod end.
Secure hoses and cables so that they have sufficient
slack for hitch movements, but cannot get caught
between moving parts of tractor, harrow or hitch. Failure
to safely route and secure hoses and cables could result
in damage requiring component repair/replacement, and
lost field time.

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 flex
harrow to the field.
This checklist presumes that the nurse tank is not yet
connected.
❑ Carefully read “A.Important Safety Information”on
page 1.
❑ Lubricate flex harrow as indicated under “Lubrica-
tion and Scheduled Maintenance” on page 29.
❑ Check all tires for proper inflation. See “Tire Infla-
tion & Warranty” on page 33.

shown in “Torque Values Chart” on page 34.
❑ Check flex harrow 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.

Unfold Harrow
The Flex Harrow has a single hydraulic circuit that combines the lateral (wing) and vertical (harrow) unfolding
operations. During unfold, the wings first fully unfold, and
then the harrows lower to the ground.
1. Position the hitched and folded harrow on the field to
be worked, or on suitable other ground. Unfolding
brings the tines into ground contact, and some forward movement is required to lay the sections flat.
2. Double-check that the harrow is securely hitched to
the tractor or leading implement.
Refer to Figure 6
3. Lift the transport chain off the wing pin on both
1
wings.
4. Start the tractor. Set the brakes. Operate the engine
at low rpms.
Refer to Figure 7
5. Slowly extend the fold circuit. Wings unfold (swing
back). Do not move the tractor until the wings are
fully unfolded.
6. As wings reach fully unfolded, release the brakes.
Figure 6
Transport Chain

31665
Negative Tongue Weight Hazard:
Allow no one near or especially behind the unfolding implement. During unfold the tongue weight shifts from positive to
temporarily negative. If the hitch fails or there is a hydraulic
failure, the harrow can tip over backwards or the harrows can
fall suddenly. Anyone under them could be seriously injured or
killed.
Refer to Figure 8
7. As sections begin to fold down, pull forward.
8. When the sections are on the ground, continue to
extend the fold circuit until the cylinders are fully
extended.

Transport
Loss of Control Hazard:
Do not tow the harrow behind another implement on public
roads. Tow the harrow to the field with a separate vehicle. The
leading implement may not provide sufficient lateral control of
a trailing implement at highway speeds. The total weight of the
train can also exceed the steering and/or braking capability of
the tractor. The resulting accident could cause serious injury
or death.
Loss of Control Hazard:
Use an adequate towing vehicle. Never tow an implement that
weighs more than 150% of the towing vehicle (transport vehicle must weigh at least 67% of implement). 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.
See tables below for harrow transport weights.
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph). Slow down on rough roads.

Transport Steps
Know your implement weight. If tractor capabilities are
marginal, check actual weight of implement at a scale.
1. Check that implement is securely hitched to a sufficient tractor (page 13).
2. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar, and rated for the load.
3. Attach safety chain to tractor with enough slack to
permit turning (page 13).
4. Verify correct operation of lights.
5. Fold flex harrow (page 18).
6. Hook transport chains (page 18).
7. Check that tires are properly inflated (page 33).
8. Plan the route. Avoid steep hills.
9. Always have lights on for highway operation.
10. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
11. Remember that the implement may be wider than
the towing vehicle. Allow safe clearance.
12. Transport slowly over uneven or rough terrain.

Field Operation
This implement is designed to be pulled in the field with
the harrows on the ground at all times (including turns).
Pulling for extended distances with sections lifted, or routine lifting for turns, is not recommended. Lifting for short
distances to clear residue clogs is acceptable. Lifting for
tight turns or reverse moves is required.
Equipment Damage Risk:
Do not pull for extended distances when partially raised.
Do not routinely raise for turns. Such practices cause premature wear of cylinders, pins and frame components. Such wear
is not covered by the warranty.
Equipment Damage Risk:
Lift for tight turns and reverse moves. Tight turns can result in
a section moving backward. Never back up with harrows on
the ground. If the inside tire stops or rolls backward, the turn is
tight and requires lift.
Field Set-Up Checklists
Use the following tables to develop a final checklist for
your tractor/flex harrow configuration. Additional or fewer
steps may be necessary depending on tractor features,
flex harrow options and planting accessories.

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 fully unfold or use stands 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 flex harrow for several hours, check
all bolts to be sure they are tight.
2. Maintain proper air pressure in tires.
3. Clean flex harrow on a regular basis. Regular and
thorough cleaning will lengthen equipment life and
reduce maintenance and repair.
4. Lubricate areas listed under “Lubrication and
Scheduled Maintenance” on page 29.
5. Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Great
Plains dealer.

Great Plains Manufacturing, Inc. Maintenance and Lubrication 27
Hydraulic Maintenance
As with any hydraulic system, contamination is the most
common cause of performance problems and premature wear. Make a special effort to properly clean
quick couplers prior to attaching the hoses to tractor, and
never let them fall to the ground.
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines.Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of paper or cardboard,
NOT BODY PARTS, to check for suspected leaks. Escaping
fluid under pressure can penetrate the skin, causing serious
injury. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.
Bleed only at JIC and NPT fittings.
Never try to bleed a QD (Quick Disconnect) fitting.
Avoid bleeding at ORB fittings. The O-ring is likely to be
torn if any pressure remains in the circuit.
Crushing Hazard:
When reconnecting fittings at fold cylinder ports, verify that a
0.063in (1⁄16in, 1.6mm) orifice plate (Great Plains part number
196-430D) is installed at each port. A missing plate could
result in a dangerously fast unfold, which might result in
equipment damage, injury or death.
System Contamination Risk:
Always use liquid pipe sealant when adding or replacing NPT
(National Pipe Thread, tapered thread) pipe-thread fittings. To
avoid cracking hydraulic fittings from over tightening, and to
keep tape fragments from clogging filters, do not use plastic
sealant tape.
Over-Torque and Leak Risks:
JIC (Joint Industry Conference 37° Flare) fittings do not
require high torque. Excess torque causes leaks. JIC and
ORB (O-Ring Boss) fittings do not require sealant.

Bleeding Hydraulics
Normally the hydraulics are bled during final pre-delivery,
and bleeding should not be required prior to first use.
Bleeding may be required after hydraulic maintenance,
or if the hydraulic system is in an uncertain state.
1. Hitch the harrow to a tractor.
2. If the harrow is folded, verify that the wing lock
chains are engaged (page 16).
3. Connect the hydraulics to a hydraulic source, such
as a tractor remote.
4. Set the source circuit to Float to relieve any pressure
in the lines.
5. Disconnect both base and rod ends of all fold cylinders.
6. Support the cylinders with ports facing up, and with
cylinders oriented so that rods cannot strike implement parts when at full extension.
7. Orient cylinders with base ends higher than rod
ends. Set circuit to Neutral.
One cylinder at a time:
8. Crack (slightly loosen) a JIC connection at a cylinder
base end.
9. Extend the circuit slowly until fluid appears at the fitting.
10. Set the circuit to Neutral. Tighten the fitting.
11. Repeat step 8 through step 10 for the remaining cylinders.
12. Retract the cylinders. Set circuit to Neutral.
13. Orient cylinders with rod ends higher than base
ends.
One cylinder at a time:
14. Crack (slightly loosen) a JIC connection at a cylinder
rod end.
15. Extend the circuit slowly until fluid appears at the fitting.
16. Set the circuit to Neutral. Tighten the fitting.
17. Repeat step 14 through step 16 for the remaining
cylinders.
18. Set circuit to Float.
19. Re-pin base and rod ends of cylinders to center section and wing lugs.
20. Test fold function carefully (page 16).
Negative Tongue Weight Hazard:
Make certain that harrow is securely hitched to a tractor
before unfolding. An unhitched harrow can tip over backwards
during folding and unfolding if the tongue is not secured.
Crushing and Equipment Damage Hazards:
Bleed after servicing cylinders or their hoses. Air in the system
makes it hazardous to fold the implement. If it is necessary to
service hydraulics while folded, the first unfold is especially
dangerous. Wing motion can be uneven or jerky in fold.
Unfolding wings could fall suddenly. Anyone nearby could be
seriously injured or killed. Equipment damage is likely.
High Pressure Fluid Hazard:
Wear safety goggles and gloves. The bleed procedure requires
partially opening pressurized hydraulic lines. Escaping fluid
under pressure can penetrate the skin, causing serious injury.
If an accident occurs, seek immediate medical assistance from
a physician familiar with this type of injury.

Appendix B - Initial Setup
This Appendix covers setup tasks performed only once,
or at infrequent intervals. Routine setup tasks are covered in “Preparation and Setup” on page 12. Perform
Appendix B tasks first. Some of these items may already
have been done by your Great Plains dealer:
a. Configure hitch (below and page 36)
b. Configure tine angle (page 37).
c. Install options not dealer-installed:
Install Row Extensions (page 39)
Install Wing Extensions (page 40)
Hitch Configuration
The standard FH6000HD hitch is a Category IV
single tang. The FH6000HD includes components for
converting the hitch to clevis or to Category III.
Great Plains recommends operating with the tongue
level with the ground. Machine operation is relatively
unaffected by hitch height, but the hitch must be matched
to the tractor or towing implement.
Each hitch configuration (Category IV, Category III and
clevis) requires a specific orientation of the base hitch.
93
Post-Delivery Checklist
1. Read and understand “A.Important Safety Information” on 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. See “Lubrication and Scheduled Mainte-
nance” on page 29.
4. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See
“Safety Decals” on page 5.
5. Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation & War-
ranty” on page 33.

2. Orient the hitch as required for the hitch type
(upright, recessed notch down for Category IV), and
position it at the height desired.
3. Re-secure the chain support and hitch with both
bolts . Use both bolts. Secure through 2 holes in
45
chain support, 4 holes in tongue lugs and 2 holes in
hitch casting .

Hitch Failure Risk:
Verify that there are TWO grade 8 bolts through:
TWO holes in chain support ,
FOUR holes in tongue lugs, and
TWO holes in hitch casting .
If any of these components is secured by only a single bolt,
machine damage is likely. The hitch could fail entirely, causing
a highway accident resulting in serious injury or death.

Clevis Hitch
Refer to Figure 20
The base hitch must be upright (with the recessed notch
on the bottom) for this configuration. This places the
tongue weight on the base hitch, and not the clevis.
1. Select one each:

Hitch Failure Hazard:
Install the hitch base and assemble the clevis parts as shown.
Incorrect installation or assembly may result in failure of the
clevis bolt, leading to hitch failure. This could result in a serious highway accident or severe machine damage.
93
Category III Hitch
The base hitch must be inverted (with the recessed
notch on the top) for this configuration. Set the
V-block to allow some vertical articulation of the draw
bar pin. Always use at least one cushion .

Tooth Angle
Refer to Figure 21
Tine tooth angle is set by the tooth angle plate .
The tine teeth are factory-set with the sharp break
side toward the direction of motion ( ).
1
This pulls the teeth at 40° off vertical (50° relative to the
ground). This angle is suitable for most conditions, has
no speed restrictions, usually creates a more optimal
seedbed, and provides easier residue flow.
For a more aggressive tine angle of 22° off vertical (68°
relative to the ground), reverse all harrow sections at
their chain connection to the arms.
Excess Wear / Irregular Results Risks:
Do not exceed 41⁄2 mph (7.2 kph) with tines at 22°.
Machine loads are much higher.
Tine sections may also hop on the ground.
To change tine angle:

Spot Implement
1. With the harrow directly hitched to a tractor (not to
another implement), fully unfold the implement in
field conditions (page 16). Allow enough room for the
tractor to approach either end of the harrow sections.
Pull forward to lay the sections flat on the ground.
Disconnect/Move Leading Chains
Refer to Figure 22
2. Disconnect the trailing end of the leading chains
from the harrow sections. Remove and save only the
lock nut:
