Maintenance
1. Understand procedure before doing work. Use
proper tools and equipment.
2. Work in a clean, dry area.
3. Lower the implement. Put tractor in Park, turn off
engine. To prevent unauthorized starting, remove
key before performing maintenance or service
work.
4. If work must be performed with wings raised, set
the wing tilt locks to the road position.
5. Make sure all moving parts have stopped and all
system pressure is relieved.
6. Relieve hydraulic pressure before disconnecting
hydraulic lines or performing any work on the
system.
7. Do not work underneath any hydraulically
supported components. Hydraulics can settle,
leak, or be accidentally lowered. If working
underneath hydraulically supported components
is necessary, secure implement with stands or
suitable blocking beforehand.
8. Disconnect electronic monitor and lighting
harness from the tractor before servicing or
adjusting electrical systems.

handling equipment adequate for weight involved.
5. Tighten wheel bolts only to the specified torque.

Turbo-Max Table of Contents Index Safety Information
Great Plains | 588-015M | 2019/01/31 4
High Pressure Fluids
1. Escaping fluid from holes in hydraulic lines is
difficult to spot. Do not use your hands or bare
skin to search for suspected leaks; instead, use a
piece of cardboard or wood. If injured by
escaping hydraulic fluid, see a medical
professional immediately. Exposure can result in
gangrene or severe allergic reaction.
2. Check that hydraulic fittings are tight and all
hydraulic hoses and lines are in good condition
before applying pressure to the system.
3. Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
Transporting
1. As with transporting any piece of heavy
machinery, comply with all local laws and
regulations before and during transport process.
2. Transport only at recommended transport speed
for implement. Some rough terrains require a
slower speed. Sudden braking can cause a
towed load to swerve and upset.
3. Before towing implement on roads, make sure to
empty out all material from the hoppers or boxes.
4. Know transport height and width of implement.
5. Do not tow an implement that, when fully loaded,
weighs more than 1.5 times the weight of towing
vehicle.
6. Keep clear of overhead power lines and other
obstructions when transporting.
7. Do not fold or unfold the implement while the
tractor is moving.
8. Reduce speed when turning, and make as wide a
turn as possible. Turning tractor too tight can
cause implement to tip over.
9. When towing on a trailer, secure implement with
tie downs and chains.
10. When towing on a trailer, sudden braking can
cause a trailer to swerve and upset. Reduce
speed if trailer is not equipped with brakes.
Safety Chain
1. Use a chain with a strength rating equal to or
greater than the gross weight of towed machinery.
2. Replace chain if any links or end fittings are
broken, stretched or damaged.
3. Do not use safety chain for towing.
Safety Lights and Devices
1. Always use safety lighting. Slow-moving tractors
and towed machinery can create a hazard when
driven on public roads. They are difficult to see,
especially at night.
2. If equipped, use flashing warning lights and turn
signals whenever driving on public roads.
3. Use safety devices provided with implement.
4. Keep safety lights and signs clean and visible from
front and rear of machine.
5. Keep lights in operating condition.
Shutdown and Storage
1. Park the tractor and implement on a solid, level
surface where children normally do not play.
2. Fold and tilt wings.
3. Put tractor in park or set the parking brake. Turn
off engine and remove switch key to prevent
unauthorized starting.
4. Wait for all components to come to a complete
stop before leaving the operator’s seat.
5. Turn lockout valve and wing lock levers to locked
position to prevent the wings from lowering.
6. Detach the tractor. Secure the implement using
blocks.
Proper Waste Disposal
1. Dispose of waste properly to avoid threatening
the environment and ecology. Potential harmful
waste includes oil, fuel, filters, and batteries.
2. Use a leak-proof container for draining fluids. Do
not use a food or beverage container that may be
mistaken for a consumable product.
3. Do not drain or pour waste onto the ground,
down a drain, or into any water source.
4. Contact your local environmental or recycling center
for the proper way to recycle or dispose of waste.

Turbo-Max Table of Contents Index Preparation and Setup
Great Plains | 588-015M | 2019/01/31 10
Preparation and Setup
This section helps you prepare your tractor and
Turbo Max for use, and covers tasks that need to be
done for new machines, seasonally, or when the
tractor/Turbo-Max configuration changes.
Before using the Turbo-Max in the field, you must
hitch it to a suitable tractor, inspect systems and level
the Turbo-Max. Before using the Turbo-Max for the
first time, and periodically thereafter, certain
adjustments and calibrations are required.
Pre-Operation 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,
see “Hydraulic Hose Hookup” on page 12.
If machine is folded, unlock wings and open wing lock
valve then slowly unfold the unit. Make sure no one is
under the wings during the unfolding process.
Check again for hydraulic leaks and watch that hoses
do not get pinched in hinges, wing stops, etc.
After the machine is completely unfolded, raise and
lower the Turbo Max several times to purge air from
the hydraulic system. Again check for hydraulic leaks
and tighten or replace if necessary.
Check safety chain hookup. Make sure all warning
lights are hooked up and functioning correctly.
Check that all grease fittings are in place and
lubricated. “Lubrication”on page 18. 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 “Tire Inflation Chart”
on page 19.
Refold the machine slowly, then lock wings and close
wing lock valve. Always place wing locks in locked
position when moving from field to field. Put transport
locks into place. You are now ready to go to the field.
Hitching Turbo Max to Tractor
!
Hitch to a tractor for highway transport or field
operations.
DANGER: Crushing Hazard
Do not stand or place any body part between turbo max and
moving tractor. You may be severely injured or killed by being
crushed between the tractor and turbo max. Stop tractor engine
and set parking brake before attaching cables and hoses.
1. Raise tractor three-point arms (if equipped)
clear up to clear Turbo-Max.
2. For TWO-WHEEL DRIVE and MFWD trac-
tors, 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 posi-
tion, hitch damage may occur if pinned solid.
Pin in center position for transport to maintain
maximum steering control.
3. Use jack (1) to raise and lower turbo max
tongue. Back tractor draw bar into alignment
with hitch (2). Secure with a locking hitch pin.
Secure safety chain (3) to an anchor on the trac-
tor.
Negative Tongue Weight Hazard
Make certain that turbo max is securely hitched to the
tractor or leading implement before unfolding. An
unhitched turbo max can tip over backwards during
folding and unfolding if the tongue is not secured.

Turbo-Max Table of Contents Index Electrical Hookup
4. Retract jack foot (1). Re-orient jack to storage
position. After hitching tractor to turbo max,
store jack on storage stub (4) on Turbo-Max
tongue.
Lock Drawbar
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 14, for safe
transporting.
Electrical Hookup
1. Make sure tractor is shut down with accessory
power off before making connections.
2. Connect lighting connector and any options or
after-market electronics to tractor outlets.
3. Tie up excess cable, allowing enough slack for
the unit to make turns.

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 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.
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 max 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.
Transport Locks
1. Once the cylinders are connected, raise the unit
completely. If the transport locks (1) are in place
on cylinders (2), remove them at this time.
2. Store the transport locks (1) on the sides of the
center frame. Stick pin (3) through tube on the
sides of the center frame between the frame and
carrier tire.

Wing Folding/Unfolding
Unfolding
1. If the wing lock levers are in the locked position,
turn handle (1) until set securely into the unlock
position.
2. Turn down pressure valve (2) so handle is facing
the outside of the machine.
3. Once the transport and wing locks are raised and
wing fold valve is in the open position (as
shown), unfold the wings from the tractor termi-
nal.
Operating Wing Lock Valve
The wing locking valve (2) is located on the
bypass/down pressure valve (6). To close
the locking valve, turn handle (5) 90
degrees, to keep wings from unfolding.
4. Once the machine is unfolded, raise and lower
the machine several times to purge air from the
lift system. Again, watch for any leaks and
tighten if necessary.
Front to Rear Leveling
Level Machine On Flat Surface
Pre-leveling of machine should be done on a
good level surface.
1. If your machine is equipped with the turnbuckle
option use the following steps to level your
machine. Lower machine so front coulter gangs
are 2.5 - 5cm off of ground. Loosen jam nut (1)
with turnbuckle wrench (2) (stored on rear pegs
of hitch). Adjust the turnbuckle (3) at the front
of machine to level it front to back. (Shorten to
bring front down, extend to bring front up).
2. When the front coulter gangs are the same dis-
tance off ground as rear coulter gangs re-tighten
jam nut (1).
Level Bar Spring Adjustment
1. To adjust the level bar spring assembly to the
preset position of 49cm, loosen jam nut (1) with
turnbuckle wrench (stored on rear pegs of hitch).
2. Adjust nut (3) until the 49cm dimension is
reached between backside of spring guide (4)
and front side of level bar spring rod plate (5).
3. Re-tighten the jam nut (2) to secure.

Wing Adjustment
1. Once the machine is level fore to aft, the wings may
be leveled. Start by unfolding the wings. Lower the
lift cylinders down until center coulter gangs are
2.5 - 5 cm off of ground.
2. Set the wings to match the depth of the center.
Start by loosening jam nut (1) with turnbuckle
wrench (stored on rear pegs of hitch). Turn the
turnbuckle (2) to adjust (shorten turnbuckle to
run shallower and lengthen to run deeper).
3. Run machine in field with wings unfolded and
down pressure applied. If wings are not making
contact or running too deep into the soil, make
additional adjustments to turnbuckle.
Gang Cylinders
Check Gang Angle
Check gang angle adjustment annually.
Always adjust the front gangs first and then
the rear.
1. With front gang cylinders (1) in the full retract
position, the gang bar (2) should be 7.5cm from
tubes (3). If gang bar is not 7.5cm from tubes,
loosen allen screw (4) on clevis on rod end of
cylinder and shorten cylinder rod (6) by turning
cylinder rod. Re-tighten allen screw.
2. After the center is set, adjust the wings the same
way.
3. When the front gang adjusting cylinders - see
“Front Gang Angle Adjustment” on page 13 -
have been adjusted and are in the full retract
position the rear gang bar (6) should be parallel
to back frame tube.
4. If rear gang bar (6) is not parallel to back frame
tube, remove pin (7) from turnbuckle end (8).
Turn clevis to adjust gang bar length.
5. Re-install pin (7) when adjustment is made.
6. Unlock jam nuts from both ends of the gauge
link (9). Turn rod until indicator (10) - located
on front of the machine’s right wing - reads 0°.
7. Re-tighten jam nuts.
