Introduction
Great Plains welcomes you to its growing family of new
product owners. Your Turbo-Chisel TCN5107-5313 has
been designed with care and built by skilled workers using
quality materials. Proper setup, maintenance, and safe
operating practices will help you get years of satisfactory
use from the machine..
Before placing the machine into service for the first time,
read and understand this manual, in particular the
“Important Safety Information”, pages 5 to 9. Have all
operators read this manual before allowing them to work
with the machine.
Description of Unit
The TCN5107, TCN5309, TCN5311 and TCN5313 are
pull-type primary vertical tillage chisels. The TCN 5107 is
a one section machine for narrow (3m) transport. The
TCN5309, TCN5311 and TCN5313 are three section
machines that fold for narrow (3m) transport.
A row of hydraulic-adjustable Turbo coulters fractures the
ground 7-15 cm directly ahead of the shanks.
Two rows of shanks on 76.2 cm centers allows for residue
to flow through the machine. The effective spacing of the
two rows of shanks is 38.1 cm. The shanks can fracture
the ground up to 30.5 cm deep.
The TCN models offer optional shank configurations. The
configurations can have heavy duty parabolic shanks,
medium duty parabolic shanks and/or chisels shanks.
The chopper wheel or buster bar are the two optional TCN
finishing attachments. Finishing attachments are placed
behind the last row of shanks to level the soil.
An optional rear hitch is available for pulling implement/
tanks that do not impose high vertical loads on the hitch,
e.g., vertical load < 350kg.
Brakes are optional on TCN models. Service brakes are
operated by air or hydraulic lines to the tractor. Chock
blocks are provided in both brake options to prevent
movement of the machine while not connected to the tractor. Chock blocks are manually placed.
Do not modify the TCN except as instructed by Great
Plains. Do not use attachments other than as provided by
or authorized by Great Plains.

Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL1 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, and the colour Safety Red, indicate an
imminent hazard 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, and the colour Safety Orange, indicate a
potential hazard 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, and the colour Safety Yellow, indicate a
potential hazard 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 10, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
1. Symbols and colours in this manual, and on north american models, are based on ANSI standard Z535.
Decals on international models are based on ISO standard 3864.

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 hear-
ing 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.
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.
566-170M03/17/2014
Great Plains Manufacturing, Inc.Important Safety Information7
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.
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.
Transport Machinery Safely
Maximum transport speed for implement is 30 kph.
Some rough terrains require a slower speed. Sudden
braking can cause a towed load to swerve and upset.
▲ Do not exceed 30 kph or 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 national, regional and local laws.
▲ 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
“TCN Specifications and Capacities” on page 60.
▲ Reduce speed on rough roads.
▲ 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.

▲ Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual. For brake
work, see specific safety information beginning on
page 48.
▲ Work in a clean, dry area.
▲ Unfold and lower the implement, put tractor in park, turn
off engine, and remove key before performing maintenance. If work must be performed with implement raised,
use centre section lift lock and gauge lock channels provided.
▲ Make sure all moving parts have stopped and all system
pressure is relieved.
▲ Allow machine to cool completely.
▲ Disconnect battery ground cable (-) before servicing or
▲ Inspect all parts. Make sure parts are in good condition
and installed properly.
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from Turbo-Chisel
before operation.

Preparation and Setup
This section helps you prepare your tractor and
TCN5107, TCN5309, TCN5311, or TCN5313for use, and
covers seasonal tasks, and tasks when the tractor/TurboChisel configuration changes.
Before using the TCN5107, TCN5309, TCN5311, or
TCN5313 in the field, you must hitch the Turbo-Chisel 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.
Initial Setup
See “First Time Field Adjustments” on page 37 and
“Hitching a Trailing Implement (Optional)” on page 36
for pre-delivery items (normally completed by dealer),
and first-time/infrequent setup tasks, including:
❑Remove protective film from large highway reflec-
tors.
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 30).
❑Wing levelling and alignment (page 38).
❑De-grease exposed cylinder rods if so protected at
last storage.
Pre-Tilling Setup
Complete this checklist before routine setup:
❑Read and understand “Important Safety Informa-
tion” on page 5.
❑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 “Hydraulic Hose Hookup” on
page 21.
❑If machine is folded, open the two, lock valves on rod
end of fold cylinders and 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, remove
both transport locks from lift cylinders, 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 lubri-
cated. See “Lubrication and Scheduled Mainte-nance” on page 48. 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 10.
❑Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 61.
❑Put transport locks back in place on lift cylinders and
re-fold the machine slowly. Close the two lock valves
on rod end of fold cylinders. Always use the transport
locks and close lock valves when moving from field
to field. You are now ready to go to the field.

Hitching Tractor to Turbo-Chisel
Crushing Hazard:
You may be severely injured or killed by being crushed between
the tractor and implement. Do not stand or place any part of
your body between implement and moving tractor. Stop tractor
engine and set tractor parking brake before attaching cables
and hoses.
Improper Pull Hazard:
Severe injury or death may result if improper transport vehicle
is used. Hitch to 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 of the towing tractor
or implement.
For hillsides and steep slopes, set tractor wheels as wide as
possible for maximum stability.
Negative Tongue Weight Hazard:
If the rear parking jack is not set, an unhitched Turbo-Chisel
can tip over backwards during hitching and unhitching resulting in severe injury or death. If the Turbo-Chisel has a rear
attachment make sure the rear parking jack is in the parking
position, before attempting to hitch or unhitch from the tractor.
Hitch Failure Risk:
The TCN5107-5313 Turbo-Chisel’s are pull-type implements
equipped with standard Category IV single tang hitch. It may
be converted to a Category III or clevis hitch using supplied
accessory parts. Always have two (2) bolts in two holes of both
tongue and hitch.
Tractor Oil Flow Adjustment Risk:
As a general rule the tractor oil flow rate should be set to the
lower setting before starting. Oil flow can be increased to
allow the desired rate of operation as applicable. Performing
the adjustment will minimise excessive oil flow and consequent
power usage and heat generation.
Extended Parking Risk:
When the TCN5107-5313 Turbo-Chisel’s are parked for
extended periods of time, it should ideally be left in the
unfolded, i.e work position for stability, safety and ease of
access for maintenance. However, parking the TCN5107-5313
Turbo-Chisel’s in the fold position (ensuring transport locks
are engaged) is acceptable in the normal course of operation.
Drawbar Sway Risk:
Lock drawbar swing to center position to minimize any sideto-side sway to assure proper tracking in the field, and safe
road travel. See “Transport” on page 35, for safe trans-
porting.
566-170M03/17/2014
Great Plains Manufacturing, Inc.Preparation and Setup19
To prevent soil compaction on rows, set tractor wheels
between rows.Raise tractor three-point arms (if equipped)
clear up to clear Turbo-Chisel.
1. 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.
Clevis Hitch
Refer to Figure 4
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.
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.

Hydraulic Hose Hookup
Great Plains hydraulic hoses are color coded to help you
hookup hoses to your tractor outlets. Hoses that go to the
same remote valve are marked with the same color.
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting 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. If an accident occurs,
seek immediate medical assistance from a physician familiar
with this type of injury.
Refer to Figure 8
To distinguish hoses on the same hydraulic circuit, refer
to handle symbols.
• 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, implement or hitch. Failure to safely route and secure hoses and cables could
result in damage requiring component repair/replacement, and lost field time.
Clean all hydraulic couplings and hook hoses to tractor.
Two TCN5107-5313 braking (trailer braking) systems are
available:
• Dual-line air system (Figure 9) with wheel chocks
(Figure 11) for parking and
• Single-line hydraulic (Figure 10) with wheel chocks
(Figure 11).
In both systems, the tractor’s trailer brake remote port(s)
operate a hydraulic slave cylinder on the Turbo-Chisel.
Tractor trailer braking systems are normally integrated
with the tractor brakes, and operate the trailer brakes
when tractor brakes are used during tractor movement.
The trailer braking system may or may not be integrated
with the tractor parking brake system.
Trailer brakes typically are not automatically engaged
when the tractor transmission is in Park, and may not be
engaged by any tractor Emergency Brake.
Both brake systems include four chock blocks to be manually installed for parking the TCN5107-5313. The tractor
cannot set the implement wheel chocks.
Figure 9
Air Brake System
41999
Braking Hazards:
Make sure the operator understands when Turbo-Chisel
brakes are engaged and when they are released (make a record
of tractor behaviour on page 33).
Also understand and comply with tractor operational restrictions when trailer brakes are used. For example, it is generally
necessary to inter-tie split brakes, and avoid differential
(steering braking) if trailer brakes are used.

which meters tank air to the master cylinder on the
implement.
Braking Hazard:
Do not use the TCN5107-5313 with a “single-line” air brake
system. This Turbo-Chisel is designed for transport speeds
that require an air brake system to be “dual-line”. A singleline tractor system cannot charge the tank that powers the
Turbo-Chisel brakes.
Roll-Away Hazard:
When unhitching, disconnect the red (control) line first. This
sets the brakes on the implement.

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
TCN5107-5313 Turbo-Chisel to the field.
❑Carefully read “Important Safety Information” on
page 5.
❑Lubricate Turbo-Chisel as indicated under “Lubrica-
tion and Scheduled Maintenance” on page 48.
❑Check all tires for proper inflation, “Tire Inflation
Chart” on page 61.
❑Check all bolts, pins, and fasteners. Torque as shown
in “Torque Values Chart” on page 63.
❑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, dis
connecting 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.
566-170M03/17/2014
Great Plains Manufacturing, Inc.Operating Instructions25
Unfolding and Folding
Unfold/Fold: Safety Information
Electrocution Hazard:
Keep clear of overhead power lines when unfolding, operating, folding or transporting the machine. Machine is not. At
higher voltages, electrocution can occur without direct contact. Any line voltage present on implement, implement or
tractor can cause severe injury or death.
Overhead crushing hazard:
Unfold and fold implement only if fold hydraulics are bled free
of air and fully charged with hydraulic oil. Keep away and
keep others away when unfolding or folding.
Danger crushing hazard:
An energized hydraulic circuit can activate the fold cylinder
causing serious injury or death. Avoid the hazard by relieving
pressure before shutting down the tractor and removing the
key. Once the hydraulic circuit is de-energized, the shut-off
valve may be opened. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
Pinch Point and Crushing Hazards:
Keep people away from the implement and tractor during folding. Risks include pinching or crushing at pivot points and at
multiple sites in pivoting assemblies.
Use wing fold locks. If a hydraulic failure occurs, or hydraulic
levers are moved, unlocked wings could fall suddenly causing
a major road accident, or crushing anything near the wings,
resulting in death or serious injury, and property damage.
Falling Hazard - Tires Not a Step:
Do not use tires as steps or platforms. All tires can be in light
ground contact, or free to spin, when implement is lowered.
Equipment Damage Risk:
Raise implement before unfolding or folding. Folding with
implement lowered causes wing ground engaging components
to dig or drag sideways. Damage is likely.
Wing Tilt Risk:
Fold only while parked on hard level ground. If unfolding
across a slope or while moving, implement may become unstable and damage to implement components and surrounding
property. Damage is likely.

Crush/Pinch Hazards:
Make sure the transport locks are engaged. Lift and re-lower if
it is not. If the transport locks are not installed, install transport locks, in the transport position the implement will slowly
lower after hydraulic power is removed. If anyone is working
on or under the implement, this could result in serious injury
or death.

Lowering and Raising Turbo-Chisel
Lowering/Raising Safety Information
Crushing Hazard During Lowering:
Stay clear of wings, coulters, shanks, and attachments during
lowering and raising. Wings are extremely heavy and are
driven down with hydraulic pressure. Coulter disk and chisel
points are sharp. During lowering, coulters and chisel points
will cut or crush anything beneath them, and can cause serious
injury or death.
Crushing Hazard While Raised:
Use transport locks (page 28) when working on implement.
Without transport locks, center section and wings are held up
only by hydraulic pressure, and slowly lower over time. They
may lower more rapidly if the hydraulic system is damaged.
They lower rapidly if the hydraulics fail, or the Lift circuit is set
to Float or Retract.
Shoving Hazard:
Chisel length changes during raising and lowering. Injury is
possible.
Implement wheels move forward during raising, and backward
during lowering. Tractor may move in some circumstances.
Set brakes / use park to avoid tractor movement. Remain clear
of all tires and row units during raise and lower.
Equipment Damage Risk:
Do not lower while any folding or unfolding operations are
under way or partially complete. Coulter disks and chisel
points can dig in or drag on ground and be damaged.
566-170M03/17/2014
Great Plains Manufacturing, Inc.Operating Instructions29
Lowering
Refer to Figure 22
17. Check that the transport locks are not on lift cylinders
and installed in storage position.
18. Unfold implement before lowering (page 27).
19. Make sure all persons are clear of danger zones,
e.g., coulters and chisel points.
Refer to Figure 23
Falling Hazard:
Do not stand on tires when implement is lowered as they may
have little or no weight on them, and may turn suddenly and
without warning if used as a step, resulting in serious injury.

Raising
Equipment Damage Risk:
Raise the implement for folding and unfolding. If lowered,
inside wing coulter disks and chisel points drag or dig sideways during fold/unfold, and damage is likely.
Equipment Damage Risk:
Always raise the implement for tight turns and reverse/backing
operations. Backing with implement lowered causes implement
plugging and damage to implement ground engaging components. Tight turns with implement lowered may damage ground
engaging implement components.
20. Make sure all persons are safely clear of implement
sections.
22. Extend cylinders until all sections are raised. Hold for
a few seconds to re-phase cylinders.
23. Set circuit to Neutral to temporarily hold sections at
raised.
.Equipment Damage Risk:
On tractors with electronic timer controls for hydraulic circuits, lift timers must be set to no more than 2 seconds longer
than needed to fully raise Turbo-Chisel. To reduce oil heating
and system wear, Do Not Set for Continuous Mode.

Great Plains Manufacturing, Inc.Operating Instructions31
Transporting the Turbo-Chisel
Transport Safety Information
Inadequate Tractor Hazard:
Tractor must weight at least 67% of the implement as towed.
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 table on next
page. Do not tow if Turbo-Chisel exceeds the load rating of the
vehicle.
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
Excessive Speed Hazard:
Maximum transport speed is 30 kph at all times, and lower
with a lighter tractor. Excess speed can result in loss of control
or inability to stop. Reduce speeds if road conditions are less
than ideal.
Collision Hazard:
Check lights and reflector regularly. Replace bulbs and faded/
worn/missing decals as required. Use lights in transport.
These features are critical to visibility, particularly with other
drivers unfamiliar with farm equipment or not expecting to
encounter a slow-moving vehicle.
Note: An installation of optional brakes on the implement
does not reduce tractor capability requirements or
increase allowed maximum transport speed.
Unexpected Wing Tilt-Down and Lowering Hazards:
Use wing locking valves (page 26). Check that implement centre section lift lock is engaged (page 27). Failure to use these
safety features can cause a major accident resulting in death,
injury and equipment damage. If locks are not engaged, and a
hydraulic failure occurs, or a circuit is unintentionally set to
Float, wings can unfold to ground contact, or implement can
settle into ground contact.
Loss of Control Hazard, Tires:
Inflate tires to factory specifications. Tighten wheel nuts to
specifications. Under-inflated tires or loose nuts can cause loss
of control. Over-inflated tires or overt-tightened nuts can fail
suddenly and cause loss of control. Loss of control can cause a
major accident resulting in death, injury and equipment damage.

Tractor Requirements
The figures in the table below represent a limited number
of configurations. The weight of your Turbo-Chisel can
vary by hundreds of kilograms, even if it is the same base
model, due to installed options and/or after-market
equipment.
If your tractor weight or capability is in question, take
your Turbo-Chisel to a scale and get a precise weight.
Transport Checklist
❑Plan the route. Avoid steep hills. Keep clearances in
mind. Folded, your TCN5107-5313 is nearly
3.12m high and is 3m wide.
❑Hitch.
Check that implement is securely hitched to a sufficient tractor (page 18). Always use a locking-style
hitch pin sized to match holes in hitch and draw-bar,
and rated for the load.
❑Check that tires are properly inflated. Remember
that the implement may be wider than the towing
vehicle. Allow safe clearance.
❑If implement is equipped with optional brakes:
With tractor in Park, and with tractor parking brake
set, place chock blocks in transport position
(page 22).
❑Always have lights on for highway operation.
❑Comply with all national, regional and local safety
laws when travelling on public roads.
❑Release all brakes and travel with caution.

Great Plains Manufacturing, Inc.Operating Instructions33
Brake Operation (option)
Implement wheel brakes are optional. There are brake
shoe pairs on each of the outside transport wheels. The
shoe pairs are operated by two independent systems:
1. The “service” or “trailer brake” system is controlled
by the tractor. It is connected to the tractor with a
single hydraulic line or two air lines.
2. The implement can be parked by manually placing
chock blocks on either side of the transport tires.
Set manual chock blocks before unhitching implement. Block
tires if brakes are not installed, and for extra safety in case
brake system is tampered with or is not in working order.
Parking jack is not sufficient restraint for a implement parked
on un-level ground. An unsecured implement. could roll away,
causing an accident resulting in death, injury and substantial
property damage.
Both versions of the trailer brake system to the tractor are
spring-release on the implement. Unless the chock blocks are
set, implement service braking is released shortly after
unhitching the implement.
Note: The wheel chock system is not a true emergency
brake system, as there is no safe way to set the
chock blocks when the implement id in motion.
This manual therefore refers to it only for parking.
Machine Damage Risk:
Make the implement chock block removal part of your transport check-list. The tractor cannot place the chock blocks in
the transport position. Transporting with chock blocks in the
park position will result in tire or chock block damage.

Figure 26
Parking Brake (Chock Blocks)
29589
Service Brake Operation
If optional brakes are installed and connected, the
hydraulic/hydraulic or air/hydraulic systems automatically
work in conjunction with the tractor’s own brakes.
Application and release of tractor brakes during tractor
motion applies and releases the service brake system on
the implement.
Know Your Tractor Systems:
Application of tractor Parking and/or Emergency brakes may
or may not operate the implement service brake system,
depending on the design of the tractor systems.
Consult your tractor manual for details on when remote
brake ports are engaged and released. Note any variance from general behaviour in the table at right. Make
sure the tractor operator knows when implement brakes
are engaged and released.

Single-Line Hydraulic Brake Operation
In this system, a single hydraulic line from the tractor
operates a de-intensifier cylinder on the implement,
which is coupled to the implement master cylinder.
The implement brake hydraulic lines are separate from
the tractor’s line.
With the hydraulic/hydraulic system, braking is immediately available when the tractor hydraulic system is
active.
Dual-Line Air/Hydraulic Brake Operation
In this system, the “supply” (yellow or blue coded) line
charges a reservoir air tank on the implement. The
“service” (red coded) line meters air from the
reservoir to a booster cylinder, which operates the
implement’s hydraulic brake lines.

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.
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 18).
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 18).
4. Verify correct operation of lights.
5. Instal transport locks (page 28).
6. Check that tires are properly inflated (page 61).
7. Plan the route. Avoid steep hills.
8. Always have lights on for highway operation.
9. Do not exceed 32 kph (20 mph). Comply with all
national, regional and local laws when traveling on
public roads.
10. Remember that the implement may be wider than the
towing vehicle. Allow safe clearance.

Hitching a Trailing Implement (Optional)
Note: Maximum rear drawbar vertical loading-350kg.
Ensure the TCN ia unfolded.
1. Raise machine to attain a suitable height to attach
the trailing implement.
2. Reverse the TCN up to the implement, ensuring that
the drawbars are correctly aligned allowing a slight
clearance to enable the machines to be coupled
together.
3. Attach the hydraulic hoses between the TCN and the
implement.
4. Reverse the TCN and couple the two machines
together.
5. Fully raise both machines into the road transport
position. Fold the machine(s) if necessary.
Final Field Checklists
Use the following tables to develop a final checklist for
your tractor/Turbo-Chisel configuration.
Mechanical ChecklistPage
❑Turbo-Chisel hitched18
❑Hitch pin locked
❑Safety chain secured to tractor or leading
implement
❑Parking jack stowed18
❑Check all tire pressures61
❑Transport locks and locking valves are in

27
Ensure that no fouling occurs between the TCN and the towed
machine.
Note: Any tineson the towed machine should be adjusted
so that they do not engage the soil (or should be removed altogether).
Field Operation
This implement is designed to be pulled in the field with
the chisel engaged (including wide 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 wide 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 chisels on the
ground. If the inside tire stops or rolls backward, the turn is
tight and requires lift

First Time Field Adjustments
Pre-Leveling of Machine
Note: Pre-leveling of machine should be done on a good
level surface.
Front to Rear Leveling
Refer to Figure 29
1. Lower the machine until the front row of shanks are 1 to
2” above the surface. At this point, remove the snap
wire pin from the turnbuckle lock, swing lock off
turnbuckle and adjust the hitch turnbuckle to adjust
the fore and aft. The front corner of the main frame
should be 1/2 to 1” lower than the rear corner.
2. Now the turnbuckle lock may be swung back onto
hitch turnbuckle and the snap wire pin may be reinstalled.
3. If machine needs leveled from front to rear when running in field, 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.

Wing Adjustment (3-Section Wings)
Refer to Figure 30
4. Once the machine is level fore to aft, the wings may be
leveled (Models 5309-5313). Start by unfolding the
wings to a rigid position.
5. Completely extend the wing fold cylinders and check
the wings for levelness. If machine is not level, fold
wings back up, close the locking valves, and install
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.
6. Remove the two 3/8 x 1 1/4 boltsand either add more
shimsto raise wings or take shims out to lower wings.
7. Re-instal bolts and tighten to specs, “Torque ValuesChart” on page 63. Open locking valves and unfold
wings.
8. If machine is not level when fold cylinders are completely extended and running in the field, repeat same
procedure to level wings.
Refer to Figure 31
9. Once machine is pre-leveled, raise and lower the gangs
completely to cycle and purge air from these cylinders

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 33
4. 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.
Figure 33
Turbo Coulter Adjustment
41983
5. 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 3”
deeper than the rear row of shanks. In certain conditions, such as spring chiseling, shallower chiseling
depths are desired. The front shanks can be adjusted
up 3” so they are at the same operating depth as the
rear shanks. This will allow 6-8” chiseling depths with
all shanks operating at the same depth.
03/17/2014566-170M
40TCN5107-5313Great Plains Manufacturing, Inc.
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
6. 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 34
7. 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.
8. Tighten jam nuts securely.
9. 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.

10. 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.
11. 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 36
12. 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.

to lifting stob on outside of implement tongue. See
“Hitching Tractor to Turbo-Chisel” on page 18.
4. If an attachment is installed, remove rear jack from
storage position and pin securely to rear jack stand
on the rear of the implement. Adjust the jack stand
to allow the jack to engage the ground.
5. If ground is soft, place a wide block or plate under
the jack or jacks to increase contact area.
6. Securely install chock blocks to prevent jack from
digging or sliding off plate.
7. For dual line air brakes, disconnect the red (control)
gladhand connector first, at the tractor, then the blue
supply connector, and store each connector in its
matching colour-coded gladhand holder on the
implement.
8. Un-hook electrical lines and protect with any plugs or
caps provided.

Maintenance and Lubrication
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:
You may be severely injured or killed by being crushed under a
falling implement. Always use transport locks when working near
or under a raised implement.
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to penetrate the skin. 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. If injured, seek
immediate medical attention from a health care provider familiar
with this type of injury.
After using implement for several hours, check all bolts to
be sure they are tight.
1. Securely lock up implement before working on it.
2. Lubricate areas listed under “Lubrication and Sched-uled Maintenance” on page 48.
3. Check for air leaks at hose connections.
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. Inflate tires as specified on “Tire Inflation Chart”on
page 61.
6. Replace any worn, damaged or illegible safety
decals. Order new decals from your Great Plains
dealer. “Safety Decals” on page 10.
7. 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.
8. Replace or rotate worn parts as needed -- hinge
bolts, clevis pins, bearings, sweeps, shanks, etc.
566-170M03/17/2014
9. 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.
10. Check drag bolts for loosness or excessive wear.
Replace broken or bent teeth. Your drag is an important part of the tillage operation.
11. 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.

Maintenance Lift Lock
Crush and Pinch Hazards; Equipment Damage Risk:
Do not rely on hydraulics to hold the implement at lift. Use the
transport locks provided. Unlocked lift cylinders settle over time.
Implement sections can crush anyone working under them. Implement links can pinch or crush anyone working near them.
Locks are provided to hold all implement in raised position
for maintenance, and for raised unfolded storage. The transport locks are used for routine transport.
Steps to install locks presume a starting configuration of
implement unfolded and lowered:
1. Raise the unfolded implement.

Brake Line Charge and Bleed
Prior to first use, and after replacing any components
that carry brake fluid, and during periodic flushing of the
brake system, the brake lines need to be bled.
1. Spot the machine on a level surface at a safe distance from any ignition sources (brake fluid is flammable). Unless conditions are dry and calm, use a
sheltered area, to keep moisture and contaminants
out of brake fluid. Leave the tractor hitched to provide braking action to systems.
2. Unfold the machine and block the machine tires to
prevent movement. Do not set the machine’s own
parking brakes, as this restricts cylinder movement.
3. Put tractor in Park. Do not set tractor parking brake if
it also operates trailer brakes.

Brake Drum and Liner Maintenance
Great Plains recommends having brakes serviced by
trained and fully equipped brake technicians.
Non-Asbestos Fibers Hazard:
Most recently manufactured brake linings are asbestos-free.
However, non-asbestos brake linings may contain one or more
of a variety of ingredients, including glass fibers, mineral
wool, aramid fibers, ceramic fibers and silica that can be
health risks if inhaled.
Scientists disagree on the extent of the risks from exposure to
these substances. Exposure to silica dust can cause silicosis, a
non-cancerous lung disease. Silicosis gradually reduces lung
capacity and efficiency and can result in serious breathing difficulty. Some scientists believe other types of non-asbestos
3
2
4
3
5
Figure 47
Air System Filter Screen
fibers, when inhaled, can cause similar diseases of the lung.
Silica dust and ceramic fiber dust are known to the State of
California to cause lung cancer. U.S. and international agencies have also determined that dust from mineral wool,
ceramic fibers and silica are potential causes of cancer.
For silica, OSHA has set a maximum allowable level of
exposure of 0.1 mg/m3, 8-hour time-weighted average.
Some manufacturers of non-asbestos brake linings recommend that exposures to other ingredients be kept
below 1.0 f/cc, 8-hour time-weighted average.
Scientists disagree, however, to what extent adherence
to these maximum allowable exposure levels will eliminate the risk of disease that can result from inhaling nonasbestos dust.
The following procedures for servicing brakes are recommended to reduce exposure to non-asbestos fiber dust,
29592
03/17/2014566-170M
52TCN5107-5313Great Plains Manufacturing, Inc.
a cancer and lung disease hazard. A Material Safety
Data Sheet (MSDS) is available from Federal Mogul Friction Products, U.S. telephone (540) 662-3871. Request
MSDS WNRE-05-155-4.
Use caution to avoid creating, breathing or ingesting dust
when servicing brakes. Check for applicable laws, regulations and insurance/enterprise policies prior to commencing work.
Recommended Work Practices
Separate Work Area - Service brakes in an area where
these precautions are always taken for all work. Wear
clothes used only for brake work.
Respiratory Protection - Wear a respirator equipped
with a high-efficiency (HEPA) filter approved by NIOSH
or MSHA for brake work.
Wear respiratory protection at all times during brake servicing (including grinding or machining brake drums),
beginning with the removal of the wheels, through shop
cleanup after completion of brake work (including emptying vacuums, changing HEPA filters and rag disposal).
Procedures for Servicing Brakes
• Service the removed brake assembly in a negative
pressure enclosure. The enclosure should be
equipped with a HEPA vacuum and worker arm
sleeves. With the enclosure in place, use the HEPA
vacuum to loosen and vacuum residue from brake
parts.
• Alternatively, use a catch basin with water and a biodegradable, non-phosphate, water-based detergent to
wash the brake drum and other brake parts. Apply the
solution with low pressure to prevent dust from becoming airborne. Allow the solution to flow between brake
drum and brake support. Thoroughly wet the wheel
hub and brake assembly components to control dust,
prior to removal of brake shoes. Wipe parts clean with
a cloth.
• If an enclosed vacuum system or brake washing
equipment is not available, carefully clean the brake
parts in open air. Use a fine mist from a pump spray
bottle to wet parts. Use a solution containing water,
and, if available, a biodegradable, non-phosphate,
water-based detergent. Thoroughly wet the wheel hub
and brake assembly components to control dust, prior
to removal of brake shoes. Wipe parts clean with a
cloth.
Dust Control - Use only HEPA-equipped vacuum cleaners. Never blow dust with an air gun. Do not dry brush
parts.
Cleaning Fluids - NEVER use carcinogenic solvents,
flammable solvents, or solvents that can damage brake
components as wetting agents.
Work Area -. Clean work areas with a HEPA-equipped
vacuum cleaner or by damp wiping. NEVER use an ordinary shop vac, compressed air or dry sweepers.
When replacing a HEPA filter, wet the used filter with a
fine water mist. Bag and carefully dispose of the used filter.
Hygiene - Wash hands immediately after brake work,
and before eating, drinking or smoking. Clean clothes
with a HEPA-equipped vacuum before removing them.
Keep food and drink out of the work area.
Shower after work. Do not wear work clothes home. Use
a vacuum equipped with a HEPA filter to vacuum work
clothes after they are worn. Launder them separately.
Waste Disposal - Dispose of discarded linings, used
rags, cloths and HEPA filters with care, such as in sealed
and labeled plastic bags. Consult applicable EPA,
national, regional and local regulations on waste disposal.
Regulatory Guidance - OSHA, NIOSH, MSHA, and
EPA, are regulatory agencies in the United States. These
references are to provide further guidance to employers
and workers employed within the United States. Employers and workers employed outside of the United States
should consult the regulations that apply to them for further guidance.

Brake Shoe Replacement
Check brakes for wear, contamination and damage seasonally or every 9600 km (6000 miles).
1. Prior to commencing work, review the safety information on page 51. Have necessary safety equipment
and tools on hand. Make sure workers understand
the hazards and how to avoid them.
2. Review the entire procedure. Great Plains suggests
performing a complete operation on one wheel, or
one pair of wheels, at a time, so that there are fullyassembled wheels to use as an assembly reference.
3. Spot the machine on a level surface. Unfold the
machine.
4. Block the wing and rear machine tires to prevent
movement. Do not set the machine’s own parking
brakes, as the drums cannot be removed with the
brakes.
Possible Asbestos Hazard:
If you are unable to confirm that you are removing and installing Great Plains approved parts, you may have linings that
contain asbestos. Some aftermarket brake shoes may contain
asbestos, and require strict, complex and costly safety procedures not covered in this manual.
If shoe replacement is indicated, use only parts supplied or
recommended by Great Plains. The original brake linings, and
Great Plains supplied or approved linings contain no asbestos.
Unapproved parts may also appear to fit, but will not function
correctly.
Note: Inspection of the brakes may also reveal a need to
refinish drums and/or replace other brake parts. Although not strictly part of brake maintenance, you
may need to repack bearings (generally the outer),
and it may be necessary to replace a worn or damaged inner seal (and repack the inner bearing).
Refer to Figure 48
5. If left hitched, put the tractor transmission in Park,
release tractor service and parking breaks, and disconnect the trailer brakes at the hitch. Set tractor
parking brake only after trailer brake disconnection
If unhitched, release air brakes by opening dump
1
valve. Pull down on cap to release. Push up.
6. Jack up and support one or both machine transport
axles.
7. Be wearing and using recommended safety equipment for the remainder of these procedures.
8. Spin the wheels, checking for evidence of excess runout at the braking surface of the drums.
9. Remove wheels. If you have more than one wheel
removed at a time, mark on them where they came
from (L/R and inside/outside), as the tire tread pattern
is direct.

11. Carefully pull hub and drum assembly from spindle. Outer bearing may fall loose.
12. Inspect inner seal, bearings, hub and drum for
wear and damage - for drum, see “Brake DrumMaintenance” on page 58).
13. Keep inner and outer bearing components separated. They are different parts.
Refer to Figure 50
14. Inspect brake shoe origin. See Warning at right.
Great Plains supplied shoes are stamped “AL-KO”
on the web face and have bonded linings.
15. Clean brake dust from assembled parts, and from
individual parts as removed.
16. Inspect brake linings. Check for 1.6mm (
minimum thickness (exclude thickness of shoe pad),
and absence of grease, contamination, deep scores,
chipping, or excessive heat fractures. Hairline heat
fissures are not unusual and do not require shoe
replacement.
17. Inspect brake shoe retaining and operating hardware. Check for wear or damage to holes, pins and
springs. Check for weak springs. Springs must completely retract shoes when brakes are released.
Note: Sound practice is to replace springs when replac-
ing brake shoes.
18. Check wheel cylinder for evidence of leaks.
If no parts need replacing, skip to step 49.

Brake Drum Maintenance
Refer to Figure 55
46. Inspect the shoe surface (the inside rim). Normal
appearance is dull gray, with no more than light scoring and light wear.
One or two light score marks are not cause for resurfacing or replacement. If there are any questions
concerning the condition of a drum, consult an
expert.
Replace or resurface a drum that is heavily scored,
worn to more than 0.51mm (0.020in) oversize, or has
0.38mm (0.015in) or greater run-out.
Brake Drum Resurfacing
47. A standard drum lathe is suitable for machining the
shoe surface.
Wear a respirator equipped with a HEPA filter approved by
NIOSH or MSHA when grinding or machining brake drums. In
addition, do such work in an area with a local exhaust ventilation system equipped with a HEPA filter.
When removing surface, do not exceed the maximum diameter cast in the brake drum.
48. Be sure to remove any metallic chips and contamination resulting from drum machining.
Re-Mount Hub and Drum
Refer to Figure 56
49. Repack any bearings removed.
50. If replacing inner bearing seal, orient it with the
seam side out (away from bearing). Seat the seal so
that it is completely inside the narrow diameter of the
hub, and close to, but not touching the bearing
2
cup.
Seals are hollow metal structures and are somewhat fragile.
The are not intended to be in contact with the bearings. When
installing them, carefully align them so they are concentric
with the shaft hole. Apply insertion force across the entire face,
or at least equally along the entire outside diameter (as close
to the seal O.D. as possible).
51. Carefully place drum/hub assembly on spindle.
52. Insert re-packed outer bearing.
53. Add spindle washer and castle nut.
54. Tighten nut until drum/hub does not turn freely.

Test and Adjust Brakes
While the machine axle is still elevated, test both the service and the parking brake systems.
60. Hitch a tractor equipped with trailer brake remote.
Connect the braking systems. Put the tractor in Park,
but release any brakes that operate the trailer service brakes.
61. Have someone spin one brake-equipped machine
wheel, and stand clear.
62. Slowly engage the tractor service brakes. If the
wheel does not stop spinning, this may merely indicate that the self-adjusters have not yet seated.
Cycle a second time.
63. Check for unusual noises and failure to brake. Check
that the wheel spins freely with brakes released.
64. Spin another machine wheel. Stop it with the tractor
brakes. Check braking action. The self-adjusters
may already be seated for this and the remaining
wheels.
65. Release all tractor braking that engages machine
braking.
66. Spin the first wheel again. Engage the machine parking brake for that side. With fresh brake linings, it
may be necessary to adjust the hand brake handle to
achieve over-center brake-set detent with acceptable
effort.
67. Spin and test brake the other wheel on that side.
68. Repeat step 66 and step 67 for the other side of the
machine.
69. Check tire inflation, set parking brakes, and lower
machine onto its own wheels.
