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,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

Page 6
TC5109-5323Table of ContentsIndexImportant Safety Information2
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
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 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 27.
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
Turbo-Chisel. 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
Information” 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 Chisel 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
lubricated. See “Lubrication” on page 25. The hubs
will come pre-greased and will not need greased at
this time.
Check that all safety decals and reflectors are
correctly 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 Values Chart” on page 29.
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 TRACDRIVE 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.
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
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 continuous 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 knob clockwise all the way in and then
backing out 1 full turn.
26. On tractor, adjust flow-control valve to low side of
flow rate.
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.

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.

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.
34. Attach safety chain to tractor with enough slack to
permit turning (page 13).
35. Verify correct operation of lights.
36. Install transport locks (page 15).
37. Check that tires are properly inflated (page 28).
38. Plan the route. Avoid steep hills.
39. Always have lights on for highway operation.
40. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
41. Remember that the implement may be wider than
the towing vehicle. Allow safe clearance.

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.

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.
Extra shims are 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
more shims to raise wings or take shims out to
lower wings.
6. Re-install bolts and tighten to specs, “Tor q ue Value sChart” on page 29.
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.
3
8 x 114 bolts and either add
Refer to Figure 17
8. When you have machine level and set to the desired
working depth, set the depth stop on the depth
stop 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 handle will change the depth approximately
1
4”.
If after setting the depth stop, the detent on the tractor
kicks out before the stop contacts the button on 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
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.
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
different 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 eyebolt by 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 bolt
and 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 screw from collar
and 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
1
the
2” bolt under the arm. To adjust the pressure,
loosen the jam nut on the back side and then adjust
1
the
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, re-tighten 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.
Lubrication
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.
