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.
