EQUIPMENT SAFETY GUIDELINES
•Safety of the operator and bystanders is one of
the main concerns in designing and developing
a Rotary Cut Mower. However, every year
accidents occur which could have been
avoided by a few moments of thought and a
more careful approach to handling equipment.
You, the operator, can avoid many accidents by
observing the following precautions and insist
those working with or for you adhere to them.
•In order to provide a better view, certain
illustrations in this manual may show an
assembly with a safety guard removed.
However, equipment should never be operated
in this condition. Keep all guards in place. If
guard removal becomes necessary for repairs,
reinstall the guard prior to use.
•Heed all safety decals and replace any that are
not legible or missing. The locations of such
safety decals are indicated in this manual.
•Never operate this equipment while using
alcoholic beverages or drugs that can hinder
alertness or coordination. Consult your doctor
about operating this machine while taking
prescription medications.
•Under no circumstances should children under
the age of 18 be allowed to work with or around
this equipment. Do not allow anyone to operate
or assemble this equipment until they have read
this manual and have developed a thorough
understanding of the safety precautions and
operation. Review safety instructions with all
users often.
•This equipment is dangerous to anyone
unfamiliar with its operation. The owner/
operator is responsible for reading and
following all of the instructions in the manual.
The operator should be a responsible, properly
qualied and physically able person familiar
with farm machinery and competent in this
equipment’s operation.
•Never exceed the limits of a piece of machinery.
If its ability to do a job, in a safe manner, is in
question - DON’T TRY IT.
•Use a tractor equipped with a Roll Over
Protective System (ROPS) and
seat belts. Only properly trained
people should operate this
machine. Always stop the PTO,
set break, shut off the tractor
engine, remove the tractor key,
and allow implement to come to a complete
stop before dismounting tractor. Never leave
equipment unattended with the tractor
running.

F-20866 2 1-17-11
•Do not modify the implement in any way.
Unauthorized modications could result in
serious injury or death and may impair the
function and shorten the life of the equipment
and void any warranty coverage.
•In addition to the design of this implement,
including safety decals and safety equipment,
accident prevention is dependent upon the
awareness, common sense, forethought, and
proper training of everyone involved in the
operation, transport, maintenance, and storage
of the machine. Also refer to safety messages
and operating instructions in each of the
appropriate sections of the tractor manual. Pay
close attention to the safety decals afxed to
both the tractor and Tillage Disc.
•The Tillage Disc is designed for speeds of 5
mph or less. Reduce speed on rough surfaces.
Speeds beyond those recommended may
cause damage to the implement and void the
warranty.
•Never place hands or feet under Tillage Disc.
Stay clear of all moving parts.
•Do not reach or place any part of your body
under the equipment until it is blocked securely.
•Never allow riders on the Tillage Disc or tractor
at any time. There is no safe place for riders.
•DISC BLADES ARE SHARP! BE CAREFUL!
Avoid situations where discs may accidentally
roll over or fall on any part of your body. Be
especially careful working with wrenches which
may slip near sharp blade edges.
•Worn edges can seriously affect the Tillage
Disc’s penetration. Check for wear before each
use and sharpen or replace if necessary.
PREPARATION
•Never operate the tractor and Tillage Disc until
you have read and completely understand this
manual, the Tractor Operator’s Manual, and any
messages found on the safety decals on the
tractor and Tillage Disc.
•Do not wear loose tting clothing or jewelry and
be sure to contain long hair around equipment.
•Always wear your seat belt. Serious injury
or even death could result from falling off the
tractor - particularly during a rollover when the
operator could be trapped under the ROPS or
the tractor.
•Ensure Tillage Disc is properly mounted,
adjusted and in good operating condition.
•Ensure that all safety guards and safety decals
are properly installed and in good condition.
•Do not operate unless all personnel, livestock,
and pets are several hundred feet away to
prevent injury by thrown objects. Never direct
the discharge chute toward anyone.
•Never operate tractor and Tillage Disc under
trees with low hanging limbs. Operators can be
knocked off the tractor and then run over by the
rotating blades.
•Stop Tillage Disc and tractor immediately upon
striking an obstruction. Turn engine off, remove
key, then inspect and repair any damage before
resuming operation.
•Stay alert for uneven terrain, holes, rocks
roots and other hidden hazards. Keep away
from drop-offs and hazards that could cause
a rollover. Use extreme care and maintain
minimum ground speed when transporting or
operating on hillsides, over rough ground and
when operating close to ditches or fences. Be
careful and slow down when turning sharp
corners and changing direction on slopes.
Do not start or stop suddenly on slopes and
avoid operating on steep slopes. In extremely
uneven terrain, rear wheels weights, front
tractor weights, and/or tire ballast should be
used to improve stability.
•Drive Tillage Disc diagonally over sharp dips
and avoid sharp drops to prevent tractor and
Tillage Disc from “hanging up”. Always move
downward on slopes, never cut across the
face. Always check tractor manual for proper
use on slopes. Practice will improve your skills
in maneuvering on rough terrain.
•A minimum of 20% of the tractor and
equipment weight must be on the tractor’s front
wheels. Without this weight, the tractor could
tip over, causing personal injury or death. The
weight may be attained with a front-end loader,
front wheel weights, ballast in the tires or front
tractor weights. When attaining a minimum
20% of the tractor and equipment weight on the

WARNING
front wheels, you must not exceed the ROPS
weight certication. Weigh the tractor and
equipment. Do NOT guess or estimate!
•The Medium and Heavy Duty Tillage Discs are
designed to t Category 1 tractors equipped
with a standard 3-Point hitch. The tractor should
have a horsepower rating between 20 and 70
hp. NOTE: Some Category 0 tractors have
very short lift arms or 5/8” diameter (Cat 0) lift
arm ball ends. These tractors are not usually
suitable for using the Heavy Duty Tillage Discs.
ASSEMBLY
Unpack all bundles and lay out the parts.
NOTE: If your tractor lift arms spacing is 32”,
place the pins on the outside of the yoke legs. If
your tractor lift arms spacing is 26” or less, place
pins on the inner side of the yoke legs.
Assemble 3-Point hitch rst.
Attach 3-Point straps to the front lower lugs using
7/8” lift pins, lock washers and 7/8” hex nuts. DO
NOT TIGHTEN AT THIS TIME.
Attach 3-Point brace to the Disc’s center beam
with ¾” - 10 x 4½” GR5 hex head cap screw and
¾” lock nut. DO NOT TIGHTEN AT THIS TIME.
Insert ¾” - 10 x 5” GR5 hex head bolt through left
side of 3-Point brace, left 3-Point strap, spacer,
right 3-Point strap and out through the right side
of 3-Point brace. Secure with ¾” lock nut. Tighten
all connections at this time.
See nished detail below.
Be very careful when working around disc
blades as the edges are sharp. Always wear
gloves.
ATTACHING TO
TRACTOR
Never stand, or allow anyone else to stand,
between the tractor and the Tillage Disc while
backing the tractor up to the hitch.
Attach to the tractor’s 3-Point hitch as described
in the Tractor’s Operator’s Manual.
It is not recommended that sway bars or chains
be used with the Tillage Disc. The draw bar
should be checked to handle the weight of the
Disc when the unit is being raised for the rst
time.
Align lower link arms of tractor to hitch lugs on
the Tillage Disc. Insert lower lift pins into lower
ball swivels and attach lynch pins. Attach top link
to upper hitch of the Tillage Disc. Secure with
pins. NOTE: When using a Category 1 quick
hitch, the lower bushing of the upper hitch of the
Tillage Disc is the connecting point.
Check to see that the Tillage Disc is level front to
back. The Disc is leveled by adjusting the length
of the tractor’s top link. Experience will allow the
operator to determine the best setting for each
application.
OPERATING
INSTRUCTIONS
Never allow anyone to stand between the
tractor and the Tillage Disc. Always stand to
the side until the tractor is in park.
Check the site for ditches, holes or obstacles
which could cause the tractor to roll. Make sure it
is clear of any debris which might cause damage
to the Disc. Check with your local utility company
for buried electrical or gas lines.
DO NOT take a ditch at 90° (straight on).
Always go in at an angle or damage may
occur.
Be sure tractor tires and rims are in good working
condition and tires are properly inated.
It is recommended that only tractors with wide
front axles be used with the Tillage Disc. Tricycle
front wheel arrangements are inherently unstable

F-20868 4 1-17-11
CAUTION
and can cause rollover accidents.
On soils with light to medium plant cover, it is
usually acceptable to disc the ground once or
twice to cut up the plant growth to prepare the
soil. In most cases, multiple passes may be
required to achieve the desired soil preparation.
Adding additional weight to the Tillage Disc will
aid it in cutting deeper into the soil. It will also
require an increase in your tractor’s horsepower.
Do not attempt to disc wet or mucky soil. All
areas should be well drained and capable of
being walked on without having soil stick to your
shoes.
Ground conditions and the nish you require will
determine the angle position of the front and rear
gangs. The sharper the angle is set, the more
aggressive the cutting action in the soil prole
will be.
If the soil is building up or sticking to the
discs, the soil is too wet and discing should be
discontinued until the ground is drier and more
workable.
The speed of the tractor will be determined
by the condition of the soil. You may need to
use more or less angle depending on the job.
Speed of the tractor should not exceed 5 mph.
Operating at faster speeds will not allow for good
penetration into the soil and can cause damage
to the blades. When you are turning, lift the unit
from the ground.
Successive passes should be made with outer
blade approximately 7” from the previous pass
to match spacing and prevent ridging.
Do NOT disc in reverse. The Tillage Disc was
designed to only go forward. For turns in tight
places, lift unit up, back into a corner or other
tight area, then lower disc to the ground and
proceed to disc forward.
Adjusting Disc Angles
By adjusting the gangs in the front and rear,
you are able to set the disc to different angles,
depending on the tillage desired.
On the Heavy Duty models there are four
positions in the front and rear. On the Medium
and Sub Compact models there are two
adjustment positions for the front and rear.
Before adjusting, raise Disc off the ground.
Adjust the desired angle by removing the bolt(s)
and nut(s), slide the gang to the desired position
and rebolt.
TRANSPORT SAFETY
•Always observe state and local laws governing
highway safety and the travel of farm
machinery on public roads.
•The use of ashing amber lights is acceptable
in most locations. However, some locations
prohibit their use. Local laws should
be checked for all lighting and marking
requirements.
•When driving the tractor and equipment on
roads or highways, use ashing amber warning
lights and a slow moving vehicle (SMV)
identication emblem. Do not exceed 20 mph.
Reduce speed on rough roads and surfaces.
•Plan your route to avoid heavy trafc.
•Always install transport locks, pins or brackets
before transporting.
•Do not drink and drive.
•Be a safe and courteous driver. Always yield to
oncoming trafc in all circumstances, including
narrow bridges, intersections, etc. Watch for
trafc when crossing or operating in close
proximity to roadways.
•Turn curves and go up and down hills only at a
low speed at a gradual steering angle. Make
certain that at least 20% of the tractor’s weight
is on the front wheels to maintain safe control.
Always check tractor manual for proper use on
slopes.
•Use extreme care and maintain minimum
ground speed when operating close to ditches
and/or fences. Be careful when turning sharp
corners.
•NEVER allow riders on either the tractor or
Tillage Disc.

WARNING
MAINTENANCE
•Good maintenance is your responsibility. Poor
maintenance is an invitation to trouble.
•Keep service area clean and dry.
•Be sure electrical outlets and tools are properly
grounded.
•Use adequate light for the job at hand.
•Make sure there is ample ventilation. Never
operate the tractor engine in a closed building.
The exhaust fumes may cause asphyxiation.
•Before working on this Tillage Disc, be certain
all moving parts on attachments have come to
a complete stop, shut off the engine, set the
brakes, and remove the ignition keys before
attempting to perform any maintenance.
•Never work underneath equipment unless it is
blocked securely.
•Always use eye and hand protection when
performing any service or maintenance.
•Check discs frequently. They should be sharp,
free of nicks and cracks and securely fastened
in place. Sharp cutting edges disc easier and
better. Check more often if discing in rocky soil
conditions.
•Periodically tighten all bolts, nuts, screws and
check that all cotter pins are properly installed
to make certain unit is safe to operate. Torque
disc gang axle nuts to 250 ft. lbs. after the rst
initial 5 hours of operation.
•When completing maintenance or service,
make sure all safety guards and devices are
installed before using the Tillage Disc.
•After servicing, be sure all tools, parts and
service equipment are removed from the
Tillage Disc.
•Where replacement parts are necessary for
periodic maintenance and servicing, factory
replacement parts must be used to restore your
equipment to original specications.
•The manufacturer and/or distributor will not be
responsible for injuries or damages caused by
use of unapproved parts and/or accessories.
•A rst aid kit should be kept readily accessible
while performing maintenance on this
equipment.
Sealed Bearings
All models contain sealed bearings. No
lubrication is required.
Disc Replacement
Be very careful when working around disc
blades as the edges are sharp. Always wear
gloves.
1. Remove the nuts, lock washers, cap screws,
and bearing top plate from both bearing
mounts that secure the Tillage Disc to the
frame.
2. Remove jam nut, axle nut, and small end cap
washer on the end of the disc gang.
3. Slide disc spacers and bearing mounts off
axle as needed to replace desired discs and
bearings.
4. Reassemble gang with new disc and
bearings.
5. Secure gang assembly to frame using nuts,
lock washers, cap screws, and bearing top
plate that was previously removed.
NOTE: If replacing notched blades, assemble
blades in a spiral pattern. Maintain proper order
of discs, spacers, and bearing mounts for easier
reassembly.
Cleaning and Storage
After each use:
•Remove debris such as clumps of dirt, grass,
crop residue, etc. from implement.
•Inspect implement and replace worn or
damaged parts.
•Replace any safety decals that are missing or
not readable.

F-20870 6 1-17-11
Before extended storage:
•Wash Tillage Disc using low-pressure water
spray. Be careful when spraying around
scratched or torn decals or near edges of
decals as water spray can peel decals off
surface. Spraying near chipped or scratched
paint can also cause paint to peel.
•Sand down scratches or edges where paint is
missing and repaint to prevent rust.
•Remove dirt from discs. Dirty or rusty discs
will pull harder in the soil and use more
horsepower.
•Inspect implement and replace worn or
damaged parts. Replace any safety decals that
are missing or not readable.
•Store the unit in an area away from human
or animal activity under a tarpaulin. The disc
blades should be resting on boards or some
other object to keep them out of the soil.
