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.

VT1100-20 - VT1100-30 Table of Contents Index Important Safety Information
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 VT1100 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.

Great Plains | 588-685M | 06/20/2023 Table of Contents Index 3
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 VT1100 in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions under “Turbo Max Specifications and
Capacities” on page 37.
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 VT1100 while the tractor is
moving.
Shutdown and Storage
Lower VT1100, put tractor in park, turn off engine, and
remove the key.
Secure VT1100 using parking jack provided.
Detach and store VT1100 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.

Great Plains | 588-685M | 06/20/2023 Table of Contents Index 13
Preparation and Setup
This section helps you prepare your tractor and VT1100
Turbo Max for use, and covers tasks that need to be
done seasonally, or when the tractor/VT1100
configuration changes.
Before using the VT1100 in the field, you must hitch it to
a suitable tractor, inspect systems and level the VT1100.
Before using the VT1100 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, see
“Hydraulic Hose Hookup” on page 16.
If machine is folded, remove the transport pins from wing
stops and open wing lock valve. (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 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 VT1100 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.
See “Lubrication” on page 36. 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 38.
Put transport locks in place, and refold the machine
slowly. Put wing stop pins in place and close wing lock
valve. Always use the transport pins when moving from
field to field. You are now ready to go to the field.

VT1100-20 - VT1100-30 Table of Contents Index Preparation and Setup
Hitching VT1100 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 VT1100 is a pull-type implement equipped with
a standard Category IV single tang hitch. It may be
converted to a Category III, Category V, Articulating
Hitch or clevis hitch using supplied accessory parts,
see “Clevis Hitch” on page 15.
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 VT1100.
2. For TWO-WHEEL DRIVE and MFWD tractors, pin
drawbar in fixed center position for field and
transport. For FOUR-WHEEL DRIVE and TRAC-
DRIVE tractors, leave one hole clearance on each
side of drawbar for field position, hitch damage may
occur if pinned solid. Pin in center position for
transport to maintain maximum steering control.
3. Use jack (1) to raise and lower turbo max tongue.
4. Back tractor draw bar into alignment with hitch (2).
5. Secure with a locking hitch pin.
6. Secure safety chain (3) to an anchor on the tractor.
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.
7. Retract jack foot. Re-orient jack to storage position.
8. After hitching tractor to turbo max, store jack on
storage stob (4) on VT1100 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 25, for
safe transporting.

3
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.

Great Plains | 588-685M | 06/20/2023 Table of Contents Index 15
Clevis Hitch
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.

2. With the square-shouldered end of the clevis (82)
up, fully seat the clevis in the upright base hitch (83).
Insert the Grade 8 bolt (48) from below. Secure with
lock nut (62).
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 (87) to allow some vertical articulation of the
draw bar pin. Always use at least one cushion (88).
1. Select one each:
(89) PPI-302V TOP PLATE - CAT 3
(87) PPI-203VR V-BLOCK
(47) 802-383C HHCS 3/4-10X3 GR5
and two:
(88) PPI-205H CUSHION
2. Set the cushions (88) inside the hitch recess, just
forward of the vertical bolt hole. Position the
V-block (87) forward of the cushions and check the
size of the resulting pinning hole. Remove a cushion
if needed.
3. Add the top plate (89). Secure from below with
Grade 5 bolt (47).

VT1100-20 - VT1100-30 Table of Contents Index Preparation and Setup
Electrical Hookup
Your VT1100 is equipped with North American Lights.
Plug the lighting connector into the tractor outlet.
Test the lights and signaling prior to highway movement.
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.
