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 5, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
03/06/2014566-224M
2TC5109-5323Great 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 Turbo-Chisel requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure at other remote, 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.
566-224M03/06/2014
Great Plains Manufacturing, Inc.Important Safety Information3
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 Turbo-Chisel in case of
breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“TC Specifications and Capacities” on page 28.
▲ 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 Turbo-Chisel while the tractor is
moving.
Shutdown and Storage
▲ Lower Turbo-Chisel, put tractor in park, turn off engine,
and remove the key.
▲ Secure Turbo-Chisel using parking jack provided.
▲ Detach and store Turbo-Chisel in an area where children
normally 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 TurboChisel for use, and covers tasks that need to be done seasonally, or when the tractor/Turbo-Chisel configuration
changes.
Before using the Turbo-Chisel in the field, you must hitch it
to a suitable tractor, inspect systems and level the TurboChisel. Before using the Turbo-Chisel for the first time,
and periodically thereafter, certain adjustments and calibrations are required.
Prior to Going to the Field Checklist
Complete this checklist before routine setup:
❑Read and understand “Important Safety Informa-
tion” on page 1.
❑Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑Make sure your tractor horsepower matches the
implement you are pulling. This is important so the
implement can do the best possible job.
❑Clean all hydraulic couplings and connect to tractor
as shown on page 13 and 14.
❑If machine is folded, remove the transport pins from
wing stops. (DO NOT remove pins if the wing is leaning against the pins or putting pressure on the pins.
Use the hydraulics to pull the wings in completely
before unpinning them.) Once the pins are removed,
slowly untold the unit. Make sure no one is under the
wings during the unfolding process.
❑Check again for hydraulic leaks and watch that
hoses do not get pinched in hinges, wing stops, etc.
❑After the machine is completely unfolded, raise and
lower the Turbo Max several times to purge air from
the hydraulic system. Again check for hydraulic leaks
and tighten or replace if necessary.
❑Check safety chain hookup. Make sure all warning
lights are hooked up and functioning correctly.
❑ Check that all grease fittings are in place and lubri-
cated. See “Lubrication” on page 26. The hubs will
come pre-greased and will not need greased at this
time.
❑Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals” on page 5.
❑Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Torque ValuesChart” on page 30.
❑Put transport locks in place and refold the machine
slowly. Put wing stop pins in place. Always use the
transport pins when moving from field to field. You
are now ready to go to the field.

Hitching Turbo-Chisel 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 TC5109-5323 Turbo-Chisel 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.
To prevent soil compaction on rows, set tractor wheels
between rows. For hillsides and steep slopes, set tractor
wheels as wide as possible for maximum stability.
1. Raise tractor three-point arms (if equipped) clear up
to clear Turbo-Chisel.
2. For TWO-WHEEL DRIVE and MFWD tractors, pin
drawbar in fixed center position for field and transport. For FOUR-WHEEL DRIVE and TRAC-DRIVE
tractors, leave one hole clearance on each side of
drawbar for field position, hitch damage may occur if
pinned solid. Pin in center position for transport to
maintain maximum steering control.
Refer to Figure 3
3. Use jack to raise and lower turbo-chisel tongue.
4. Back tractor draw bar into alignment with hitch.
5. Secure with a locking hitch pin.

2
Crushing Hazard:
Do not stand or place any body part between turbo-chisel and
moving tractor. You may be severely injured or killed by being
crushed between the tractor and turbo-chisel. Stop tractor
engine and set parking brake before attaching cables and
hoses.
Negative Tongue Weight Hazard:
Make certain that turbo-chisel is securely hitched to the tractor or leading implement before unfolding. An unhitched
turbo-chisel can tip over backwards during folding and
unfolding if the tongue is not secured.
6. Secure safety chain to an anchor on the tractor.
Refer to Figure 4
7. Retract jack foot. Re-orient jack to storage position.
8. After hitching tractor to turbo-chisel, store jack on
storage stob on Turbo-Chisel tongue.
Load Sway Hazard:
9. Lock drawbar swing to center position to minimize any
side-to-side sway to assure proper tracking in the field,
and safe road travel. See “Transport” on page 19, for
safe transporting.

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 6
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, turbo-chisel or hitch.
Failure to safely route and secure hoses and cables
could result in damage requiring component repair/
replacement, and lost field time.
To distinguish hoses on the same hydraulic circuit, refer
to, “Hydraulic Hose Hookup” on page 14. Clean all
hydraulic couplings and hook hoses to tractor.

5317-5323 Hydraulic Down Pressure
Refer to Figure 13
Note: This setup procedure is for tractors with closed-center
or pressure compensated flow hydraulic systems.
Open center hydraulics not supported.Adjust down
pressure valve as shown on decal(located on front
right hand truss), Refer to Figure 14.
Never leave tractor valve centered when unfolded with machine
in motion. Machine damage may occur when wings flex up or
down
This machine is designed for continuos hydraulic flow to the wing
fold cylinders during field operations. It is for use on tractors
having CLOSED CENTER hydraulics only. If your tractor has an
OPEN CENTER hydraulics, please consult your dealer for operating instructions.
25. Adjust the bypass/pressure reducing valve by turning
knobclockwise all the way in and then backing out 1
1
full turn.
26. On tractor, adjust flow-control valve to low side of flow
rate.
Note: The faster the flow of oil through the system the
greater the potential for oil heating, premature wear
or tractor damage.
27. Lock the fold hydraulic lever for continuous downward
oil flow.
28. Adjust bypass/pressure reducing valve knob on
implement so the pressure gauge reads 1200 psi.
Never exceed 1400 psi.
29. While watching pressure gauge , slowly open knob
until gauge reads 1100psi. Pressure might rise and
then fall off as knob is opened. If pressure exceeds
1400 psi during this step, the tractor flow is too high,
reduce tractor flow. Lock valve knob at 1100 psi.
30. Finally adjust valve to the desired wing down pressure setting. Never exceed 900 psi.
31. In field operation, lock the fold hydraulic lever for continuous downward oil flow. If wings are running too
high, increase pressure setting, knob, to level
machine. If center is too high, decrease pressure setting with knob on valve.

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
Turbo-Chisel to the field.
❑Carefully read “Important Safety Information” on
page 1.
❑Lubricate Turbo-Chisel as indicated under “Lubrica-
tion” on page 26.
❑Check all tires for proper inflation, “Tire Inflation
Chart” on page 29.
❑Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 30.
❑Check Turbo-Chisel 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.
566-224M03/06/2014
Great Plains Manufacturing, Inc.Operating Instructions19
Transport
Loss of Control Hazard:
Do not tow the turbo-chisel behind another implement on public roads. Tow the turbo-chisel 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.
32. Check that implement is securely hitched to a sufficient tractor (page 13).
33. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar, and rated for the load.

Field Operation
This implement is designed to be pulled in the field with
the machine engaged (including wide turns). Lifting for
short distances to clear residue clogs is acceptable. Lifting for tight turns or reverse moves is required.
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/Turbo-Chisel configuration. Additional or
fewer steps may be necessary depending on tractor features, Turbo-Chisel options and planting accessories.

General Operation and In-Field
Adjustments
1. Remove the transport pins, see “Transport Locks” on
page 15 and unfold machine. Make sure the fold cylinders are fully extended to allow the wings to fully flex in
the field.
2. If possible have someone observe the machine during
first time operation for levelness, front to rear and wings
to center frame.
Refer to Figure 15
3. If machine needs leveled from front to rear, remove the
snap wire pin from the turnbuckle lock, swing lock
off turnbuckle and adjust the hitch turnbuckle. When
done adjusting, be sure and swing turnbuckle lock back
down and secure with snap wire pin.

Refer to Figure 16
4. If machine is not level when fold cylinders are completely extended, fold wings back up and instal shims as
needed to level.
Note: Extra shimsare stored in manual pak. The extra
shims may be needed in the future if the hinge holes or
bolts begin to wear. There are two different thickness
of shims, you may use multiple shims to level wings.
5. Remove the two 3/8 x 1 1/4 boltsand either add more
shimsto raise wings or take shims out to lower wings.
6. Re-instal bolts and tighten to specs, “Torque ValuesChart” on page 30.
7. For best results, if at all possible, run machine at a slight
angle to the rows. This will improve trash flow and allow
for better dislodging of rootballs and will help spread the
residue more evenly across the field.

Refer to Figure 17
8. When you have machine level and set to the desired
working depth, set the depth stopon the depth stop
2
tube. This is located at the front of the machine. This
will maintain a constant depth each time after raising
and lowering machine.One full turn of the handlewill
change the depth approximately 1/4”.
Note: If after setting the depth stop, the detent on the trac-
tor kicks out before the stop contacts the buttonon
the depth stop, slow the hydraulic flow speed down. If
this problem exists, contact the factory service representative for other possible adjustments. On tractors
with a timed detent setting, set the detent so when
you raise the machine, the pump will run for 1/2 to 1
full second after full raise. If it runs longer than this,
damage to the seals of the lift cylinders may result.
Refer to Figure 18
9. Once the machine is set, running level both fore and
aft, from side to side you are ready to run. The first
part of the machine that makes contact with the soil is
the turbo coulters. These can be adjusted hydraulically
from the seat of the tractor. These coulters are
designed to cut and size, they will also help with burying residue as the aggressive turbo blades will pick up
and roll the soil.
Note: These coulters should not be run at a depth deeper
than 5”. Also, in very hard ground, be careful to try not
to force the coulters too deep as it may try to raise the
front of the machine out of the ground as this will affect the overall performance of the machine.
10. The machine can be equipped with several different
shank options. It is important to understand these
options and how they affect the soil. See a and b for
description.
a. Toggle Trip Shanks with 7” winged point. These can
run up to 11” deep and with winged points, they do an
excellent job of fracturing the soil. These shanks run 2”
deeper than the rear row of shanks.

b. Spring Reset Mounts can be equipped with several dif-
ferent shank and point configurations. The most popular
is the Parabolic Shank with a 7” winged point. This point
is similar to the ones on the toggle trip shank except It
has a “fin” on it that helps minimize shank “blow out”.
The combination of these shank assemblies and the
Toggle Trip shanks provide the best combination for
fracturing the ground completely while leaving the surface in a relatively “smooth” condition. By following the
combination with a Chopper Reel or Buster Bar, one
pass finishing in the Spring is attainable. Spring Reset
Mounts can also be equipped with a Standard Chisel
Shank which supports many point options. See chart
below for a detailed analysis of the varying point
options.

Rear Attachment Settings
Rear Chopper Reel
11. The chopper reel attachment is designed to help size
the soil and residue coming out of the back of the
machine and level the soil surface. The reels should be
run as far forward as possible without causing plugging
of the reel assemblies or the machine. In wetter conditions, they may need to be moved back some to allow
the soil to “settle” before coming in contact with the
reels. Also in wet conditions, it is not advisable to apply
down pressure on the reels as this will cause them to
plug with mud.
Refer to Figure 19
12. In order to raise or lower the chopper reel assembly, adjust
the eyeboltby loosening the jam nuts. Extend eyebolt
to lower the assembly, retract eyebolt to raise assembly.
13. Tighten jam nuts securely.
14. To adjust the chopper reels fore and aft, remove boltand
slide tubes in or out. Adjustment is 3” for each hole. The
bolt may need to move from the back hole to the front hole
or vice verse, depending on the amount of adjustment
needed. Because of weight concerns, the choppers should
run as far forward as possible while still allowing soil and
residue to flow freely from the rear shanks.

Refer to Figure 20
15. The down pressure can be adjusted two ways. For slight
down pressure, loosen set screwfrom collarand slide
collar up for more pressure. Tighten set screw to secure.
16. For added down pressure, tighten lock nut on top of
spring. This will compress the bottom of the spring,
increasing down pressure. This will also raise the chopper
reel so you will also need to re-adjust eyebolt at the bottom
of the spring bolt accordingly.

Buster Bar
Refer to Figure 21
17. The buster bar attachment is designed to knock the tops of
the ridges and to help fill the valleys behind the chisel
shanks. The down pressure can be set by the 1/2” bolt
under the arm. To adjust the pressure, loosen the jam nut
on the back side and then adjust the 1/2” bolt. To increase
down pressure, loosen the bolt. In some instances, especially when you are running the chisel very deep, the bolt
head will not be in contact with the ball joint when the unit
is out of the ground. Once the unit is lowered into the
ground, the bolt head will come in contact with the ball
joint and pressure will be applied. Once the proper tension
is set, retighten the jam nut. There are no other adjustments to this attachment.

Maintenance and Lubrication
Maintenance
1. Always use the transport lock when working on or
doing maintenance to the Turbo-Chisel. If folded, be
sure your wing stop pins are in place. Read and
understand all safety decals on your equipment.
2. During the first season of operation, and periodically
after that, check your bolts for tightness. Check
shank pivot bolts for tightness. Check shank pivot
bolts on the spring-loaded shank, these must remain
tight to prevent excessive wear on the shank assembly.
3. Replace or rotate worn parts as needed -- hinge
bolts, clevis pins, bearings, sweeps, shanks, etc.
4. Check and tighten or replace any hydraulic leaks.
Check hoses for any leaks. It is important that there
are no leaks on the equipment.
5. Grease wheel bearings and walking beams sparingly. Over greasing may cause damage to seals and
reduce the life of the bearing. Grease hinge points
periodically.
6. Check drag bolts for loosness or excessive wear.
Replace broken or bent teeth. Your drag is an important part of the tillage operation.
7. If machine is stored outdoors over the winter months,
it is a good idea to fold the machine then set it down
on the ground so all the cylinders are retracted to
protect the cylinder rods. This will extend the life of
the cylinder seals and reduce internal and external
leaks.
By following and maintaining a routine service and lubrication program, your tillage equipment will give you
many years of service.
