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.

Great Plains Mfg., Inc. Important Safety Information
Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed. Sudden braking can cause a towed load
to swerve and upset.
• 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.
• Comply with state and local laws.
• Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the
weight of towing vehicle.
• Carry reflectors or flags to mark tractor and
implement in case of breakdown on the
road.
• Keep clear of overhead power lines and
other obstructions when transporting. Refer
to transport dimensions under
“Specifications and Capacities,” page 67.
• Do not fold or unfold the wings while the
tractor is moving.
Avoid High Pressure Fluids
Escaping fluid under pressure can 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 suspected
leaks.
• Wear protective gloves and safety glasses
or goggles when working with hydraulic
systems.
• If an accident occurs, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or
gangrene may result.

Completing Setup
Install the plastic end caps into the
open ends of all the 4x3 frame tubes.
Finish plumbing the Ultra-till hydraulic
lift and gang systems from the layouts in
Hydraulics in parts manual. Cycle the
hydraulic systems to purge the cylinders of air
while checking for leaks.
You should now be ready to add the
harrow modules and the remaining gangs to
the machine. If the machine has a finishing
attachment you would install it last. See the
machine layout section 4 for proper module
dimensions and gang sizes for your unit.
The parts manual shows the harrow
module assembly with parts along with gang
parts and identification drawings.
Once the harrow modules and gangs
are installed and all of the hydraulic
procedures have been completed, you may fold
the machine to check for clearance and proper
module placement. Slowly fold the machine
while watching that hoses do not become
pinched or kinked and watch that modules
clear all obstructions.
Once the machine is folded completely,
begin to unfold slowly. Be Sure No One Is
Under The Wings When You Unfold The
Machine. Once the machine is unfolded, add
the safety decals and the product decals. Refer
to the Important Safety Information section
(page 7) for the proper placement of safety
decals.
Install the safety chain, SMV sign &
safety lights in accordance with local and state
laws. See parts manual (Frame section) for
assembly drawings and parts list.
At this point, set up of the machine is
complete and you are ready to add any
finishing attachment, rear hitches, etc… to the
machine. Be sure to consult the operating
instructions, Section 4, for the first time field
adjustments before going to the field for the
first time.

Section 4: Operating and Maintenance Great Plains Mfg., Inc.
Operating and Maintenance
Proper servicing and maintenance is the key to the long life of all farm equipment. With careful and
systematic inspection of your Ultra-till, you can avoid costly maintenance downtime and repair.
Adjustments Before Going to the Field:
1. IMPORTANT!! If you have not thoroughly
read and understood the safety section at the
front of this manual, do so at this time. DO
NOT proceed without fully understanding the
safety considerations of this machine.
2. Make sure your tractor horsepower matches
the implement you are pulling. This is
important so the implement can do the best
possible job. (Minimum of 7-8 HP per Ft.)
3. Hitch the tractor to the Ultra-till. This tool is
equipped with a reversible single tang hitch.
Use the correct size hitch pin to insure proper
performance and to minimize wear. Raise
any 3-pt arms and/or hitch attachments to
its fully raised position to clear implement.
4. 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.
5. Check safety chain to insure that it is properly
attached. Make sure all warning lights are
hooked up and functioning correctly.
6. Clean all hydraulic couplings and connect to
tractor. Each hydraulic coupling has a colored
handle on it and is marked with a cylinder,
either extending or retracting.
A. Red – Disc Gangs.
B. Green – Fold/Hydraulic Down Pressure
C. Black – Main Lift.
7. If machine is folded, remove the transport pins
from the wing stops. (DO NOT remove pins if
the wing is leaning against the pins or putting
pressure on the pins. Use the hydraulics to
pull the wings in completely before unpinning
them.) Once the pins are removed, slowly
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, wings
stops, etc.
8. After the machine is completely unfolded,
raise and lower the Ultra-till several times to
purge air from the hydraulic system. Again
check for hydraulic leaks and tighten or
replace if necessary.
9. Check the tire pressure for proper inflation
and check the tightness of the lug bolts and
lug nuts. See tire inflation chart in the
appendix section of this manual.
10. Check for any bolts that may need tightened
or retightened. Grease all the hinge points.
The hubs come pre-greased and will not need
more grease at this time.
11. Put transport lock in place and refold the
machine slowly. Put wing stop pins in place.
You are now ready to go to the field. (It is
very important not to run the machine
down the road without the transport locks
in place.)
12. Leveling the unit:
side levelness of the unit best before you
install the modules.
a). On a good level surface, lower the machine until
the cylinders are completely retracted and measure
down from the bottom of the center frame to the
ground. (Take note of this measurement.)
b). Repeat this process at each section to prelevel the machine adjusting the eyebolt on
each cylinder.
13. Front to rear leveling should be done in the
field with modules installed. This is adjusted
with the turnbuckle on the hitch.
You can adjust the side to

Great Plains Mfg., Inc. Section 4: Operating and Maintenance
Field Adjustments & General Operation Instructions
1. The Ultra-till is designed as a primary/
secondary vertical tillage tool and is designed
to leave a finished seedbed following some
form of fall or spring tillage. In a min-till/no till
operation, it may be used as a primary onepass vertical tillage tool. For best results, if at
all possible, run the machine at a slight angle
to the rows. This will improve trash flow and
help spread the residue more evenly
throughout the field.
2. The ideal working speed for turbo blades is 7
to 10 MPH. If the Ultra-till is equipped with
disc-blades, then no more than 7 MPH is
recommended due to the possibility of ridging.
3. Before starting in the field: Set the depth of the
gangs at 0 inches on the gauge. Let the
machine all the way down until the cylinders
are retracted. Set your leveling front to back
with the turnbuckle on the hitch by lengthening
or shortening. Re-set the depth of gangs
between 2 to 3 on the gauge.
4. Set the hydraulic down pressure using the
instructions provided on pages 28 & 29.
Caution: Never leave tractor valve
5.
!
CAUTION
centered when unfolded with
machine in motion. Machine damage
may occur when wings flex. The hydraulic
down pressure cylinders have no wing flex
capability and oil flow is required when the
wings flex up or down. You must have the
tractor fold hydraulic lever in continuous
downward flow or “float” position before
the wings can flex over terrain in the raised
or lowered lift position.
6. If possible, have someone observe the
machine during first time operation for
levelness – front to rear and wings to center
frame. Adjust each as needed. If ground is
soft, and the blades are running too deep,
raise the gangs to desired depth. You may
need to readjust front to back. If the ground is
hard this may raise the front and again the
front to back may need to be changed (Note:
To change front to rear, either extend to raise
the front, or shorten the turnbuckle to lower
front.) On 5-section Ultra-tills with the
hydraulic gauge wheels, set the wheels in field
position to be 1” to 2” off the ground.
7. For a final adjustment on the hydraulic down
pressure, note the action of the gang bolts as
the machine operates through the field by
watching the nuts at the top of the bolts (as
shown by arrows). If the center gang bolts are
more active than the wings, the pressure to the
wings may need to be increased. If the wing
gang bolts are cycling extensively but the
center is not, the pressure to the wings needs
to be decreased. On a five-section machine,
you need to set the outside wings with one
valve and the inside wings with the other (the
valves are marked as to which is which). Once
you have all the spring bolts across the
machine working evenly, lock the valves in
place. You may need to re-adjust these valves
as field conditions change, (i.e. ground
becomes harder as it dries out or wetter after a
rain).
8. If a basket is added for leveling, use the
eyebolt to increase or decrease down
pressure. (Note: Shorten for less pressure or
lengthen for more.)

Section 4: Operating and Maintenance Great Plains Mfg., Inc.
Maintenance and Lubrication
1. Always install all transport locks when working
on or doing maintenance to the Ultra-till. If
folded, be sure your wing stop pins are in
place. Read and understand all safety decals
on your equipment.
2. During the first season of operation, and
periodically after that, check your bolts for
tightness.
3. Check scrapers and make sure gangs turn
freely.
4. Check and tighten any hydraulic leaks. Check
hoses for any leaks. It is important that there
are no leaks on the equipment that may
change the depth when in field position.
5. Grease disc gang bearings, rolling harrow
bearings and wheel bearings sparingly
greasing may cause damage to seals and
reduce the life of the bearing. Grease hinge
points periodically:
. Over
Disc & Coulter Gang Bearings
Grease every 50 hours (sparingly)
Wheel Bearings
Grease every 50 hours (sparingly) and
check for endplay.
All Hinge Points
Grease every 10 hours.
Walking Beam Pivot Bearings
Grease every 100 hours (sparingly) and
check for endplay.
Phoenix Rotary Modules
Grease every 10 hours.
Great Plains Rolling Spike
Grease every 50 hours. (sparingly)
6. 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 of the
cylinders are retracted to protect the cylinder
rods. This will extend the life of the cylinder
seals and reduce internal and external leaks
that cause future problems maintaining a level
machine.
7. If you choose to sharpen the boron disc
blades, they must be ground instead of rolled.
By following and maintaining a routine service and
lubrication program, your tillage equipment will give
you many years of service.
