unless the Implement is securely supported or blocked up to prevent
sudden or inadvertent falling which could cause serious injury or even
death. (SG-14)
Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard.
High-pressure oil streams from breaks in the line could penetrate the
skin and cause tissue damage including gangrene. If oil does
penetrate the skin, have the injury treated immediately by a physician
knowledgeable and skilled in this procedure. (SG-15)
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items thrown by the
equipment.(SG-16)
CAUTION!PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an
Implement attached can often be noisy enough to cause permanent
hearing loss. We recommend that you always wear hearing
protection if the noise in the Operator’s position exceeds 80db.
Noise over 85db over an extended period of time will cause severe
hearing loss. Noise over 90db adjacent to the Operator over an
extended period of time will cause permanent or total hearing loss.
Note: Hearing loss from loud noise [from tractors, chain saws,
radios, and other such sources close to the ear] is cumulative over a
lifetime without hope of natural recovery.(SG-I7)

DANGER!All Safety Shields, Guards and Safety devices including
Mow only in conditions where you have clear visibility in daylight or with
adequate artificial lighting. Never mow in darkness or foggy conditions
where you cannot clearly see at least 100 yards in front and to the sides of
the tractor and mower. Make sure that you can clearly see and identify
passersby, steep slopes, ditches, drop-offs, overhead obstructions, power
lines, debris and foreign objects. If you are unable to clearly see this type
of items discontinue mowing.
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if
shields are not properly installed and maintained. Serious injury or
even death may occur unless care is taken to insure the safety of the
operator, bystanders, or passersby in the area. Do not operate this
machine with anyone in the immediate area. Stop mowing if anyone
is within 100 yards of mower.
(but not limited to) - the Deflectors, Chain Guards, Steel
Guards, Gearbox Shields, PTO integral shields , and
Retractable Door Shields should be used and maintained in good working condition. All safety devices
should be inspected carefully at least daily for missing
or broken components. Missing, broken, or worn items
must be replaced at once to reduce the possibility of
injury or death from thrown objects, entanglement, or
blade contact. (SGM-3)
(SGM-1)
(SGM-2)
DANGER!
WARNING!
WARNING!
The rotating parts of this machine have been designed and tested for
rugged use. However, the blades could fail upon impact with heavy,
solid objects such as metal guard rails and concrete structures. Such
impact could cause the broken objects to be thrown outward at very
high velocities. To reduce the possibility of property damage, serious
injury, or even death, never allow the cutting blades to contact such
obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before mowing.
Foreign objects should be removed from the site to prevent machine
damage and/or bodily injury or even death. Any objects that cannot be
removed must be clearly marked and carefully avoided by the operator.
Stop mowing immediately if blades strike a foreign object. Repair all
damage and make certain rotor or blade carrier is balanced before
resuming mowing. (SGM-5)
Many varied objects, such as wire, cable, rope, or chains, can become
entangled in the operating parts of the mower head. These items could then
swing outside the housing at greater velocities than the blades. Such a
situation is extremely hazardous and could result in serious injury or even
death. Inspect the cutting area for such objects before mowing. Remove any
like object from the site. Never allow the cutting blades to contact such
items. (SGM-6)
WARNING!Mow at the speed that you can safely operate and control the tractor and
mower. Safe mowing speed depends on terrain condition and grass type,
density, and height of cut. Normal ground speed range is from 0 to 5 mph.
Use slow mowing speeds when operating on or near steep slopes, ditches,
drop-offs, overhead obstructions, power lines, or when debris and foreign
objects are to be avoided. (SGM-7)
WARNING!
WARNING!
Avoid mowing in reverse direction when possible. Check to make sure there
are no persons behind the mower and use extreme care when mowing in
reverse. Mow only at a slow ground speed where you can safely operate and
control the tractor and mower. Never mow an area that you have not
inspected and removed debris or foreign material. (SGM-8)
Do not put hands or feet under mower decks. Blade Contact can result
serious injury or even death. Stay away until all motion has stopped and
the decks are securely blocked up. (SGM-9)
SAFETY
DANGER!
WARNING!
WARNING!
WARNING!
Replace bent or broken blade with new blades. NEVER ATTEMPT
TO STRAIGHTEN OR WELD ON BLADES SINCE THIS WILL
LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH
SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES. (SGM-10)
Do not mow with two machines in the same area except with Cab tractors
with the windows closed. (SGM-11)
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accessible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor .
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage
and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches,
and gearboxes. Periodically shut down the Tractor and Mower and clean
clippings and collected debris from the mower deck. (SGM-12)
DO NOT weld or repair rotating mower components. Welds and other
repairs may cause severe vibration and/or component failure resulting
in parts being thrown from the mower causing serious bodily injury.
See your Authorized Dealer for proper repairs. (SGM-13)
DANGER!
FLX15/10 04/06
The Mower is designed for certain mowing applications and is rated to
cut up to a specific size vegetation (see Mower Standard Equipment
and Specifications). DO NOT use this Mower to cut vegetation above
the Mower’s rated capacity or to cut any type of non-vegetative
material. Only operate this Mower on a properly sized and equipped
Tractor. Operating this Mower in an application for which it is not
designed and/or operating the Mower with the wrong size Tractor can
cause Mower component damage and equipment failure resulting in
possible serious injury or death. (SGM-14)
Always disconnect the main PTO Driveline from the Tractor before
performing service on the Mower. Never work on the Mower with the
tractor PTO driveline connected and running. Blades or Drivelines could
turn without warning and cause immediate entanglement, injury or death.
(SRM-3)
Do not turn so sharp or lift mower so high to produce a severe
"knocking" of the Driveline which will cause accelerated wear and
breakage of drive train components and could result inpossible injury
from the separated Driveline sections. (SRM-4)
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-7)
Rotary Mowers are capable under adverse conditions
of throwing objects for great distances (10 0 y ards or
more) and causing serious injury or death. Follow
safety messages carefully
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed
and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the
ground without exposed Blades;
-Passerby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material
such as rocks, cans, glass, and general debris has been removed.
DANGER!
DANGER!
FLX15/10 04/06
NOTE: Where there are grass and weeds high enough to hide debris
that could be struck by the blades, the area should be: inspected
and large debris removed, mowed at an intermediate height, inspected,
closely with any remaining debris being removed, and mowed again
at desired final height. (This will also reduce power requiredto mow,
reduce wear and tear on the Mower drivetrain, spread cut material
better, eliminate streaking, and make the final cut more uniform.)
(SRM-1)
Be particularly careful when transporting the Implement using the tractor.
Turn curves or go up or down hills only at a low speed and at a gradual
steering angle. Make certain that at least 20% of the tractor’s weight is
on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces.(STI-1)
When the Wings are folded for transport, the center of gravity is raised
and the possibility of overturn is increased. Drive slowly and use
extremecaution when turning on hillsides. Overturning the Implement
could cause the Implement to overturn the Tractor and vice versa resulting
in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-2)
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death.
Never unhitch without using the Tongue Jack. The Tongue is
very heavy. Attempting to lift the Tongue without using the Tongue
Jack could cause strains or other injury. Allowing the tongue to fall
suddenly and unexpectedly could result in crushing injury. Use
the Tongue Jack for lifting the Implement only. Overloading the
Tongue Jack can cause failure with possible serious bodily injury
or even death. (STI-4)
On a fully-assembled unit, do not remove the Wing Retaining Strap
until hoses are attached to the tractor and the Wing Cylinders are
filled with oil. Lower the Wings slowly and carefully. Keep bystanders away during operations. (STI-5)
(STI-3)
SAFETY
WARNING!
DANGER!
WARNING!
DANGER!
Secure the Implement for transport before traveling on public roads.
For pull-type Implements, secure the center axle using cylinder stops
or transport pin and properly attach a safety chain between the
Implement and Tractor. Secure wings in upright position on folding
Implements using wing transport locks. (STI-7)
Do not operate the implement while wearing loose fitting clothing.
Entanglement of the clothing with the rotating elements can result in
serious injury or even death. Stay clear of all rotating elements at all
times. (SSP-3)
Use extreme care when lowering or unfolding the implement’s wings.
Make sure no bystanders are close by or underneath the wings. Allow
ample clearance around the implement when folding or unfolding the
wings. Use extreme caution around buildings or overhead power lines.
(S3PT-5)
Make sure the PTO shield, integral driveline shields, and input shields are
is installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing. (S3PT-8)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work.
The rotating parts of this machine continue to rotate even after the PTO
has been turned off. The operator should remain in his seat for 60
seconds after the brake has been set, the PTO disengaged, the tractor
turned off, and all evidence of rotation has ceased. (3PT-10)
“Wait a minute...Save a life!”
Always disconnect the main PTO Driveline from the Tractor before
performing service on the Implement. Never work on the Implement with
the tractor PTO driveline connected and running. Rotating Parts, Blades
or Drivelines could turn without warning and cause immediate
entanglement, injury or death. (S3PT-11)
This Implement is wider than the Tractor. Be careful when operating
or transporting this equipment to prevent the Implement from running
into or striking sign posts, guard rails, concrete abutments or other
solid objects. Such an impact could cause the Implement and Tractor
to pivot violently resulting in loss of steering control, serious injury, or
even death. Never allow the Implement to contact obstacles. (S3PT-12)
(S3PT-9)
WARNING!
WARNING!
WARNING!
Before operating the Mower, check to make sure the Implement input
driveline will not bottom out or become disengaged. Bottoming out occurs
when the inner shaft penetrates the outer housing until the assembly
becomes solid-it can shorten no more. Bottoming out can cause serious
damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking
it off. A broken drive line can cause personal injury. (S3PT-18)
Allow sufficient clearance for the Implement to swing outward while
turning. Implements carried behind the Tractor will swing outside the
tire path when making turns. Contacting a solid object while turning
will cause equipment damage and possible injury. (S3PT-20)
DO NOT use a PTO adapter to attach a non-matching Implement driveline
to a Tractor PTO. Use of an adapter can double the operating speed of the
Mower resulting in excessive vibration, thrown objects, and blade and
mower failure. Adapter use will also change the working length of the
driveline exposing unshielded driveline areas. Serious bodily injury and/or
equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match
the Tractor PTO. (S3PT-14)
Relieve hydraulic pressure prior to doing any maintenance or repair
work on the Implement. Place the Mower Head on the ground or
securely supported on blocks or stands, disengage the PTO, and turn
off the engine. Push and pull the control Levers or Joystick several
times to relieve pressure prior to starting any maintenance or repair
work. (SBM-6)
Always shut the Tractor completely down, place the transmission in
park, and set the parking brake before you or anyone else attempts to
connect or disconnect the Implement and Tractor hitches.
When attaching the Implement input driveline to the Tractor PTO, it is
important that the connecting yoke spring activated locking collar
slides freely and the locking balls are seated securely in the groove on
the Tractor PTO shaft. A driveline not attached correctly to the Tractor
PTO shaft could come loose and result in personal injury and damage
to the Implement.
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO
NOT tow the Implement behind a truck or other type of vehicle. Never
tow the Implement and another Implement connected in tandem.
Never tow the Implement at speeds over 20 MPH. (STI-6)

ASSEMBLY
Two back to back cone springs are used to keep the castor assemblies tight and reduce castor whipping action.
The double jam nuts that are used to lock the castor assembly in place may need to be adjusted in order to take
up wear in components of the castor pivot.The lower nut should be adjusted to the point that the cone springs are
flattened, and then it should be backed off one half turn. Next, the lower nut should be held with a wrench so it does
not change its position, while the upper nut is tightened down onto it.
4. Connection to Tractor
Adjust the drawbar length as recommended (540 or
1000 rpm). Adjust the height of the hitch clevis so that
the frame is as level as possible. Pin clevis to the
drawbar.
Connect the hoses to the remote outlets on the tractor.
The hoses have a color-coded ties on both ends to
easily identify them. Adjust the hoses in the hose
organizer to allow sufficient slack for turning. Do not
allow the hoses to contact the driveline or become
pinched.
Move jack to its storage location on left wheel standard.
Attach safety tow chain to flex arm and tractor. Fasten
the large loop of the safety chain to the hitch, using the
1” bolt, washer, and nut. Attach the other end of the

WARNING!
Do not use safety tow chain for towing. Replace entire chain if any link or end fitting is broken,
stretched, or otherwise deformed.
5. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
ASSEMBLY
1. Start by using the driveline that was shipped with
the cutter being used.To connect the driveline to the
tractor PTO output shaft, twist driveline yoke collar and
align the grooves and splines of the yoke with those of
the PTO shaft. Push the driveline yoke onto the PTO
shaft, release the locking collar, and position the yoke
until the locking collar balls are seated onto the PTO
shaft. Push and pull the driveline back and forth several
times to ensure a secure attachment.
2. Use the driveline that was shipped with the flex arm
to connect to the flexarm and cutter.Connect the mower
driveline to the gearbox output shaft, twist driveline yoke
collar and align the grooves and splines of the yoke
with those of the gearbox output shaft. Push the
driveline yoke onto the output shaft, release the locking
collar, and position the yoke until the locking collar
balls are seated onto the output shaft. Push and pull
the driveline back and forth several times to ensure a
secure attachment.
IMPORT ANT: DO NOT use a non-CV tractor shaft. Driveline damage will occur when turning the implement.
IMPORTANT: Do not operate the PTO with the flex arm in the transport position for extended periods of time. This
may cause driveline vibration and will accelerate universal joint wear.
Remove any tape from the splined shaft, and any
booklets from the driveline. Install the shaft spacer
(A101-157) onto the splined shaft tight against the
steady bearing collar. Slide the clamp collar end of
the tractor shaft onto the splined shaft and insert the
tapered pin into the yoke. Push the yoke onto the
shaft until the groove lines up with the hole and the pin
extends through. Tighten the locknut to squeeze the
yoke onto the shaft. The protective cone on the steady
bearing may need to by unclipped to access the
locknut.
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the
groove of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could
slip off and result in personal injury and damage to the cutter.
6. Connection to Cutter
ASSEMBLY
Remove the hitch clevis from the hitch swivel on the
cutter if equipped. Insert the 3/4" bolts into the castor
wheels to lock in place.
To align the precision hitch, board the tractor and start
the engine. Back the tractor and FLEX-ARM to the
cutter until arm hitch tongue is close enough to the
cutter swivel. Then use the Flex Arm to extend the
precision hitch tongue towards the cutter hitch swivel
about a foot. Turn off the tractor engine, place the
tractor in park, and set the parking brake before
dismounting. Dismount and view to see how far is
needed to go. Keep extending the flex arm in foot
increments or as much length needed until holes are
aligned. Once the cutter is connected remove the
stabilizer bolts from the castor wheels to free the
castor wheels. The stabilizer bolts are to be removed
at all times except when backing the flex arm to
connect the cutter. Castor wheels should not be left in
the lock position after the cutter is attached, the
stabilizer bolts are not transport pins, bodily injury or
damage to the implement can result if left in.
Remove the cutter jack and place in its storage position.
Always shut the Tractor completely down, place the transmission in park,
and set the parking brake before you or anyone else attempts to connect
or disconnect the Implement and Tractor hitches. (S3PT-15)
7. Connecting Strut To Cutter
Pin the strut assembly to the mounting lugs on the arm
and cutter with the 1" bolts. The length of the strut from
pinpoint to pinpoint should be set to according to what
type of cutter is being attached. See chart for length of
strut according to cutter being used.
NOTE: All cutters will have a strut mount lug welded to
the cutter at the factory. If cutter is an older model and
does not come with the welded mounted lug, a retro-fit
weld on lug kit is available for purchase at your local
dealer.The kit consist of lug, bolt & nut, a spray can
paint, and installation instructions. Customer will be
required to weld lug then drill a 17/32” hole through the
tube and pin the safety bolt through it (the hole is
already pre-drilled on the lug itself)

2.1 ROPS and Seat Belt
A Roll-Over-Protective-Structure (ROPS) and seat belt are essential to protect the operator from falling off the
tractor, especially during a roll over where the driver could be crushed and killed. The ROPS and seat belt must
be used in conjunction with one another. Only operate the tractor with the ROPS in the raised position and seat
belt fastened. Tractor models not equipped with a ROPS and seat belt should have these life saving features
installed by an authorized tractor dealer.
WARNING!
Operate this Equipment only with a Tractor equipped with an approved roll-overprotective system (ROPS). Always wear seat belts. Serious injury or even death
could result from falling off the Tractor--particularly during a turnover when the
operator could be pinned under the ROPS. (SG-7)
2.2 Tractor Safety Devices
If transporting or operating the tractor and mower near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the
unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning
signals are obscured.
OPERATION
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or mower. Never operate the tractor PTO with the
PTO master shield missing or in the raised position.
The horsepower required to operate the mower depends on several operating factors including the vegetation to be
cut, terrain condition, operator experience, condition of the mower and tractor, and other factors. The recommended
tractor HP for the FLX15 is 85 HP . The recommended tractor HP for the FLX10 is 75 HP . The recommended tractor
HP for the S150 is 85 HP and S100 is 75 HP Operating the mower with a tractor that does not have enough power
will produce a less desirable cut and may cause tractor engine damage.
2.4 Drawbar
Position the length of the drawbar from the end of the
tractor PTO shaft to the drawbar hitch hole according
to the operating speed of the mower. If the mower is
a 540 RPM unit, position the drawbar length from shaft
end to hitch hole at 14”. For 1000 RPM mowers, set
the drawbar length at 16” for 21 spline 1-3/8” mowers
and at 20” for 1-3/4” 20 spline mowers.
2.5 Tractor Hydraulics
OPERATION
The mower deck and wings are raised and lowered with hydraulic cylinders operated by the tractor hydraulic
pump. There are several ways to configure the mower hydraulics depending on the number of tractor selective
control valves and if they are four double acting. The mower can be operated on a tractor with a minimum of four
single acting circuits. One double acting and two single acting cylinders or a three spool control valve must be
used to operate the mower equipped with hydraulic phasing cylinders.

DRAWBAR
Refer to the assembly and parts section of this manual for hydraulic system set-up or contact an authorized dealer
for the best configuration depending on your tractor hydraulic capabilities and your intended mower use.
2.6 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight
is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is
too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight
carriers can be purchased through an authorized tractor dealership.
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower
and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those
operating at 540 RPM will have a 1-3/8” diameter 6-spline shaft and those operating at 1000 RPM will have a 13/8” 21-spline shaft or a 1-3/4” 20 spline shaft. Refer to the tractor owner’s manual for instructions to change
PTO speeds on models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an overrunning clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor
dealer can provide the over-running clutch and its installation if needed.
WARNING!
WARNING!
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO.
Use of an adapter can double the operating speed of the Mower resulting in excessive
vibration, thrown objects, and blade and mower failure. Adapter use will also change the
working length of the driveline exposing unshielded driveline areas. Serious bodily injury
and/or equipment failure can result from using a PTO adapter. Consult an authorized dealer
for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
Never operate the Tractor and Mower if the Mower main driveline is directly connected to
the Tractor transmission. Tractor braking distances can be substantially increased by the
momentum of the rotating Mower blades driving the Tractor transmission even though the
Tractor clutch has been engaged. Install an over running clutch between the Tractor PTO
and the Mower driveline to prevent this potentially dangerous situation.
2.8 Tire Spacing
Tractor tires should be set a minimum of 60” apart
measured from inside of tire to inside of tire. Refer to
the tractor Operator’s Manual or consult an authorized
dealer for instructions to change tractor tire spacing.
Before getting onto the tractor, the operator must read and completely understand the mower and tractor operator
manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete
explanation.
WARNING!
3.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when getting on the tractor. Never use tractor
control levers for support when mounting the tractor. Always seat yourself in the operator’s seat and fasten the
seatbelt. Only operate the tractor and mower with the ROPS in the raised position.
Never allow passengers to ride on the tractor or mower. Riders can easily fall off and be seriously injured or
killed from being ran over by both the tractor and mower. It is the operator’s responsibility to forbid riders.
Do not mount the Tractor while the tractor is moving. Mount the
Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)

and unexpected tractor movement.
DANGER!
DANGER!
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Start the Tractor only when properly seated in the Tractor seat. Starting a
Tractor in gear can result in injury or death. Read the Tractor operator’s
manual for proper starting instructions. (SG-13)
5. CONNECTING THE FLEX-ARM TO THE TRACTOR
Use extreme caution when connecting the FLEX-ARM to the tractor. The FLEX ARM should be securely resting
at ground level with the parking jack foot. Place a block in front of and behind wheels to prevent the FLEX-ARM
from moving. Keep hands and feet out from under the FLEX-ARM and clear of pinch points between the tractor and
FLEX-ARM.
DANGER!
Always shut the Tractor completely down, place the transmission in park, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and
Tractor hitches. (S3PT-15)
1. Ensure the tractor is equipped with the correct
PTO shaft and the drawbar is set at the correct
length.
2. Using the parking jack, position the tongue clevis
to the height of the tractor drawbar.
3. Board the tractor and start the engine. Back the
tractor to the FLEX-ARM aligning the drawbar hitch
hole with the FLEX-ARM tongue clevis. Turn off
the tractor engine, place the tractor in park, and
set the parking brake before dismounting.
DANGER!
4. T o attach the Flex Arm insert the hitch pin through
the drawbar and tongue clevis. Once the pin is
inserted, attach the snap ring pin through the hole
on the hitch pin and snap in place.
5. Attach safety tow chain to flex arm and tractor.
Fasten the large loop of the safety chain to the
hitch, using the 1” bolt, washer, and nut. Attach
the other end of the chain to tractor. Refer to your
tractor operator’s manual for complete instructions
OPERATION
to attach chain to tractor. Adjust length to allow
only enough slack as is needed for turning. Lock
hook on chain. Ensure chain rating is equal to, or
greater than the gross weight of the towed
equipment.
6. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from the
tongue and place on storage bracket of FLEX-ARM.
Always shut the Tractor completely down, place the transmission in park,
and set the parking brake before you or anyone else attempts to connect
or disconnect the Implement and Tractor hitches. (S3PT-15)
Safety Tow
Chain Connection
Safety Tow Chain
If the FLEX-ARM is towed on a public roadway , a safety chain with tensile strength equal to or greater than the
gross weight of the FLEX-ARM & mower must be connected between the tractor and FLEX-ARM. This will help
control the implement in the event the tongue becomes disconnected from the drawbar. After connecting both
ends of the safety chain, drive the tractor to the right and left to check for proper chain length. Adjust length as
necessary and allow only enough slack in the chain to make a maximum turn in both directions.
5.2 Connecting the Cutter Precision Hitch to the FLEX-ARM
1. Ensure the FLEX-ARM is equipped with the correct
gearbox output shaft.
2. Using the parking jack, position the cutter tongue
clevis to the height of the FLEX-ARM precision
hitch.
3. Insert the 3/4” bolts into the castor wheels to lock
them into place when backing up.
IMPORTANT: Castor Wheel stabilizer pins need to be
inserted in the castor wheels when backing the flex
arm up to connect the mower. All other times pins should
not be in castor wheels.
4. To align the precision hitch, board the tractor and
start the engine. Back the tractor and FLEX-ARM
to the cutter until arm hitch tongue is close enough
to the cutter swivel. Then use the Flex Arm to extend
the precision hitch tongue towards the cutter hitch
swivel about a foot.Turn off the tractor engine, place
the tractor in park, and set the parking brake before
dismounting. Dismount and view to see how far is
needed to go. Keep extending the flex arm in foot
increments or as much length needed until holes
are aligned.
OPERATION
DANGER!
5. To attach the mower, place the cutter hitch pin
through the hitch clevis and hitch tongue. Insert
the 1/2” bolt, lockwasher, and flatwasher to the pin
and hitch clevis. This keeps the pin in place and
does not allow it to rotate. Attach the bushing to
the bottom of the pin and insert the roll pin to the
pin. Be sure the bolt is tightened but do not over
tighten. NEVER attach the mower to the tractor
without the bolt or roll pin attached to the retaining
pin .
Always shut the Tractor completely down, place the transmission in park,
and set the parking brake before you or anyone else attempts to connect
or disconnect the Implement and Tractor hitches. (S3PT-15)

securely attached through the Safety Chain
Attachment Location and is securely wrapped
around the mower “A” frame.
7. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from the
tongue and place on storage bracket of mower.
8. Pin the strut assembly to the mounting lugs on
the arm and cutter with 1” bolts the length of the
strut from pinpoint to pinpoint should be set
according to chart below.
NOTE: All cutters will have a strut mount lug welded to the cutter at the factory. If cutter is and older model and
does not come with the welded mounted lug, a retro-fit weld on lug kit is available for purchase at your local
dealer.The kit consist of lug, bolt & nut, a spray can or paint, and installation instructions. Costumer will be
required to weld lug then drill a 17/32” hole through the tube and pin the safety bolt through it (the hole is already
pre-drilled on the lug itself)
5.3 Connecting Mower Hydraulic Lines to the T ractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position. Keep mower hydraulic lines,
hoses, quick couplers, and swivels free of contamination. Never leave a disconnected hose end open and cap the
tractor hydraulic outlet ports when not in use. If the tractor ports,Flex-Arm ports, or mower hydraulic hose ends
become contaminated, wipe clean with a rag before connecting.
DANGER!
Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard. Highpressure oil streams from breaks in the line could penetrate the skin
and cause tissue damage including gangrene. If oil does penetrate the
skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure. (SG-15)
Hoses and breakaways are provided in order to connect to a 15’ rotary cutter with individual single acting wing
circuits. A tot al of 4 hydraulic circuits are required. Two of the circuits require float positions on the control
valves in order to operate the single acting wing circuits on the rotary cutter .
FLX10 Hydraulic Circuit Requirements
Hoses and breakaways are provided in order to connect to a 10’ rotary cutter with single acting wing circuit. A
total of 3 hydraulic circuits are required. One of the circuits requires a float position on the control valve in order
to operate the single acting wing circuit of the rotary cutter .
Hydraulic Line Support
After connecting the Flex-Arm hydraulic lines to the tractor ,and mower hydraulics to the Flex-Arm, support the
hoses with the equipped brackets. Ensure that hoses do not contact the driveline, do not bind while turning, and
do not become pinched or kinked.
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport pins to lower the mower
wings and deck. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position
until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float
position and repeat process several more times to purge all air from the system. Ensure wings are entirely
supported by the cylinders before removing the transport pins. NEVER drive out pins and NEVER remove
transport pins that have tension on them.
6. SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a
more uniform cut, distribute clippings more evenly , require minimal tractor work, and follow the contour of uneven
terrain. Note: A void very low cutting heights, striking the ground with the blades gives the most damaging shock
loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be
thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to
contact the ground.
DANGER!
6.1 SETTING CUTTING HEIGHT
The cut height for the center section is set by extending
or shortening the depth collar located on the center lift
cylinder. Cutting height for the wing cylinders will be
automatically controlled by the hydraulic phasing
system. Depth stops are also provided on the wing
cylinders as back up for fine adjustments.
IMPORT ANT: If depth control stops are not set at the
same height as the center cylinder, internal damage
may occur to the phasing cylinders.
Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to
prevent sudden or inadvertent falling which could cause serious injury
or even death. (SG-14)
OPERATION
The cutter should always be operated in the highest
position that will produce the desired cutting results.
Operating at increased heights will minimize the
chances of blades contacting the ground and
discharging debris.
To facilitate safe and efficient operation, the mower
should be operated with the deck approximately 3/4”
LOWER IN THE REAR THAN THE FRONT.
Operating the mower with the rear of the deck slightly
lower than the front provides better suction, lifting the
grass and creating a clean cut with less windrowing.
For heavier applications, the front of the mower may
need to be raised an additional 1/2" - 1".
Adjust the lift rods linking the tongue to the rear axle
until mower is at least 3/4” lower in the rear that than
the front. To lower the front, lengthen the lift rods and
to raise the front shorten the rods. IMPORT ANT : Adjust
the lift rods the same amount and maintain equal tension
in the rods. Improper adjustment may cause rods to
snap or bend. Retighten the jamnuts after the deck
pitch has been set.
Leveling Rod Adjustments
7. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
1. Start by using the driveline that was shipped with
OPERATION
the cutter being used.To connect the driveline to the
tractor PTO output shaft, twist driveline yoke collar and
align the grooves and splines of the yoke with those of
the PTO shaft. Push the driveline yoke onto the PTO
shaft, release the locking collar, and position the yoke
until the locking collar balls are seated onto the PTO
shaft. Push and pull the driveline back and forth several
times to ensure a secure attachment.
2. Use the driveline that was shipped with the flex arm
to connect to the flexarm and cutter.Connect the mower
driveline to the gearbox output shaft, twist driveline yoke
collar and align the grooves and splines of the yoke
with those of the gearbox output shaft. Push the
driveline yoke onto the output shaft, release the locking
collar, and position the yoke until the locking collar
balls are seated onto the output shaft. Push and pull
the driveline back and forth several times to ensure a
secure attachment.
IMPORT ANT: DO NOT use a non-CV tractor shaf t. Driveline damage will occur when turning the implement.
IMPORTANT: Do not operate the PT O with the flex arm in the transport position for extended periods of time. This
may cause driveline vibration and will accelerate universal joint wear.
WARNING!
7.1 Constant Velocity (CV) Driveline
For mowers equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor and
mower must be determined to ensure the joint angle does not over-extend which can cause CV joint damage.
Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at angles up to
70°. Angles greater than 80° can result in mechanical damage to the CV joint and mower driveline.
The Constant Velocity joint must be lubricated every 8 hours of operation as specified in the Maintenance Section.
Failure to properly lubricate the joint will result in accelerated wear and joint component failure.
1. With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make a
hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower frame or
tongue.
2. Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before
dismounting.
3. Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and then
angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center line of the
yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the joint cannot be
angled at least 10°, there is a potential problem of over-angling the joint while making sharp turns.
4. Solutions: To ensure the joint is not damaged, check the following:
-Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.
-Move the tractor rear tires wider apart to limit the tractor turning radius.
-Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning
radius that maintains a safe operating angle and note this position to the operator.
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the groove
of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could slip off
and result in personal injury and damage to the cutter.
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline
which will cause accelerated wear and breakage of drive train components and could result
in possible injury from the separated Driveline sections. (SRM-4)

8. PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the mower and tractor must be performed. This
includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and
functional, and performing needed repairs. Do not operate the mower and tractor if the pre-operation inspection
reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing parts
as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time and
repair cost can be avoided.
DANGER!

•Deep gouges in the blades surface are present, or
•Gouges or chipped areas in the cutting edge are larger than 1/2”, or
•The material on the leading edge has been worn away by more than 1/2”.
Failure to replace abnormally worn blades may lead to catastrophic failure of the blade and
ejection of the broken part with tremendous force which may cause serious bodily injury or
death!
Remedy: Replace Blades more often.
Adjust mower height for mowing
conditions to eliminate blade-toground contact.
Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and
precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the
weight of the mower and the tractor operating controls are set for safe transport. To ensure safety while driving
the tractor with an attached mower, review the following.
WARNING!
Transport only at safe speeds. Serious accidents and injuries can result from operating
equipment at unsafe speeds. Understand the Tractor and Mower and how it handles before
transporting on streets and highways. Make sure the Tractor steering and brakes are in
good condition and operate properly. Before transporting the Tractor and Mower, determine
the safe transport speeds for you and the equipment. Make sure you abide by the following
rules:
1. Test the Tractor at a slow speed and increase the speed slowly. Apply
the Brakes smoothly to determine the stopping characteristics of the
Tractor and Mower. As you increase the speed of the Tractor the stopping
distance increases. Determine the maximum safe transport speed for
you and this Equipment.
2. Test the equipment at a slow speed in turns. Increase the speed through
the turn only after you determine that it is safe to operate at a higher
speed. Use extreme care and reduce your speed when turning sharply to
prevent the Tractor and Mower from turning over. Determine the maximum
safe turning speed for you and this equipment before operating on roads
or uneven ground.
3. Only transport the Tractor and Mower at the speeds that you have
determined are safe and which allow proper control of the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases,
use extreme care and reduce your speed in these conditions. When operating in traffic,
always use the Tractor’s flashing warning lights and reduce your speed. Be aware of
traffic around you and watch out for the other guy. (SG-19)
This Implement is wider than the Tractor. Be careful when operating or transporting
this equipment to prevent the Implement from running into or striking sign posts, guard
rails, concrete abutments or other solid objects. Such an impact could cause the
Implement and Tractor to pivot violently resulting in loss of steering control, serious
injury, or even death. Never allow the Implement to contact obstacles. (S3PT-12)
Operation Section 4-23
OPERATION
9.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is unclear.
Ensure the 3-point control lever is in the lowered
position and the PTO is disengaged before starting
the tractor.
9.2 Brake and Differential Lock Setting
Make sure the tractor brakes are in good operating
condition. Tractor brakes can be set to operate
independently allowing single rear wheel braking
action or locked together to provide simultaneous rear
wheel braking. FOR MOST DRIVING AND MOWING
CONDITIONS, THE BRAKE PEDALS SHOULD BE
LOCKED TOGETHER TO PROVIDE THE MOST
EFFECTIVE BRAKING ACTION.
WARNING!
OPERATION
Always disengage the tractor differential lock when turning. When engaged the differential lock will prevent or
limit the tractor from turning. During normal mowing conditions, locking the differential provides no benefit and
should not be used.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty
brakes. When operating down a hill or on wet or rain slick roads, the braking distance
increases; use extreme care and reduce your speed in these conditions. When operating
in traffic, always use the Tractor’s flashing warning lights and reduce your speed. Be
aware of traffic around you and watch out for the other guy.
9.3 Operating the Mower Wings
Wings are positioned with hydraulic cylinders. Ensure the hydraulic cylinders and lines are filled with oil by
holding the valve control levers in the raised position until the cylinders fully retract (wings) and extend (center).
Only operate the mower with both wings fully lowered, NEVER operate the mower with a raised wing. Wait until
the blades are at a complete stop before raising wings.
T o raise mower wings, drive the unit to a level area and
retract the wing hydraulic cylinders. DO NOT raise
wings with the mower positioned on an embankment

Operating Position
To lower the wings, remove the transport lock pins and secure pins at storage location. DO NOT drive out
transport pins that have tension on them. Af ter removing pins, extend wing hydraulic cylinders and fully lower
wings.
Wing hydraulic control valves should be set in the float detent during operation to allow the mower to follow the
contour of uneven terrain and to prevent the wings from creeping up. When extending a wing over a ditch for
mowing, place the control valve lever detents in the center position for greater stability .
WARNING!
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-5)
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor, flex arm, and mower . Moving slowly at first will also prevent the tractor from rearing up and loss of steering
control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the
operator from stopping quickly during an emergency . If the power steering or engine ceases operating, stop the
tractor immediately as the tractor will be difficult to control.
WARNING!
Perform turns with the tractor, flex arm and mower at
slow speeds to determine how the tractor with an
attached flex arm and mower handles a turn. When
operating the flex arm and mower the overall working
length of the unit is increased. Allow additional
clearance for the flex arm and mower when turning,
especially if the wings are lowered and the flex arm is
extended. The mower extends to the right 3’ from the
FLX15 and 16” from the FLX10. Extra precaution should
be taken to avoid hitting parked vehicals,sign, road
structures, bystanders,and animals due to the overall
length and width of the implements.
To avoid overturns, drive the tractor with care and at
safe speeds, especially when operating over rough
ground, crossing ditches or slopes, and turning
corners. Rear tractor tire spacing should be increased
when working on inclines or rough ground to reduce
OPERATION
the possibility of tipping. Utilizing the flex arm will
increase safety during operation. The tractor does not
have to ride on the ditch slopes there by reducing the
possiblities of a rollover.
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury.
(S3PT-20)
Use extreme caution when operating on steep slopes.
Keep the tractor in a low gear when going downhill.
DO NOT coast or free-wheel downhill.
Practice steering and maneuvering the tractor, Flex Arm and mower in an open field or parking lot before operating
the mower. Use extreme care when backing the equipment. The mower will not react to backing in the same
manner as it does when the mower is connected directly to the tractor. Practice backing until you can safely
control the direction and movements of the Flex Arm and mower. Back up at a slow speeds to ensure you maint ain
control and direction of the mower. Use care to make sure the mower is not backed in to a parked vehicle, sign,
road structures, bystanders, or animals. If you do not feel that you can safely operate and back the equipment
combination than obtain further training before operating this Flex Arm and mower.
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the main driveline
inner profile will penetrate into the outer housing to its
maximum depth until the assembly becomes solid
(driveline is at its extreme shortest length). This type
of abusive operation can cause serious damage to
the tractor and mower drive by pushing the PTO into
the tractor and through the support bearings or
downward onto the PTO shaft, breaking it off.
WARNING!
When confronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damage to over collapse of the driveline
may occur.
When crossing such terrain, the wings should be fully
lowered for a lower center of gravity and added
stability.
Inclines and ditches should be approached along a
line which is at an angle as shown. This type of path
will reduce the possibility of over-collapse of the
driveline and resulting damage. If the gradient is so
steep that such as approach increases the possibility
of a tractor roll-over, select an alternate crossing path.
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing
may allow the driveline to come loose from the Tractor which could cause bodily injury to
the operator or bystanders and/or extensive damage to the Tractor or Implement
OPERATION
INCORRECT: DO NOT approach ditch straight on.
CORRECT: Approach ditch at an angle
When operating the tractor and mower across slopes and inclines, through ditches, and other uneven terrain
conditions, it is important to maintain sufficient deck to ground clearance. Blade contact with the ground may
cause soil, rocks and other debris to be thrown out from under the mower resulting in possible injury and/or
property damage. Ground contact also produces a severe shock load on the mower drive and to the mower
blades resulting in possible damage and premature wear.
THE OPERA TOR MUST COMPLETEL Y UNDERST AND HOW TO OPERA TE THE TRACTOR, FLEX ARM, AND
MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the
Safety and Operation Sections of the flex arm, mower and tractor operator’s manuals. These manuals must be
read and explained to any operator who cannot read. Never allow someone to operate the mower and tractor
without complete operating instructions.
Before starting any mowing operation, the operator must become familiar with the area to be mowed and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
DANGER!
DANGER!
OPERATION
Extreme care should be taken when operating near loose
objects such as gravel, rocks, wire, and other debris. Inspect
the area before mowing. Foreign objects should be removed
from the site to prevent machine damage and/or bodily injury
or even death. Any objects that cannot be removed must be
clearly marked and carefully avoided by the operator. Stop
mowing immediately if blades strike a foreign object. Repair
all damage and make certain the blade carrier is balanced before
resuming mowing. (SGM-5)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the Mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-6)
10.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure there
are no foreign objects that the mower blades could
hit or become entangled with. Remove all foreign
objects and debris. If objects are too big to remove,
mark them clearly and be sure to prevent the mower
blades from contacting them.
If you hit a solid object or foreign debris, stop the flex arm,mower, and tractor at once. Immediately idle the engine
speed and disengage the PTO. Wait for all mower rotating motion to stop, then raise the mower and move the
tractor and implements off the object. Inspect the area and remove, or mark the location of the debris. Inspect the
condition of the mower and make any needed repairs immediately. Make sure the blades are not damaged and
the carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and only operate the tractor, flex arm and mower with the ROPS in
the raised position. If the tractor, flex arm, or mower hits a tree stump, rock, or bump, a sudden movement could
throw you off of the seat and under the tractor ,flex arm, and mower The seat belt is your best protection from
falling off the tractor and the ROPS provides protection from being crushed during a tractor roll-over .
10.2 Bystander/Passersby Precautions
If a bystander comes within 100 yards of the tractor while the mower is being operated, stop the tractor at once,
idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the 100
yard distance.
DANGER!
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general
debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades,
the area should be: inspected and large debris removed, mowed at an intermediate height, inspected
closely with any remaining debris being removed, and mowed again at the desired final height. (This will
also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material
better, eliminate streaking, and make the final cut more uniform.)(SRM-1)
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (100 yards or more) and causing
serious injury or death. Follow safety messages carefully.
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The mower wings
must be completely lowered and the deck positioned at a safe mowing height. NEVER engage the PTO with the
mower wings in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the
on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear
unusual noises or see or feel abnormal vibrations, disengage the PTO immediately . Inspect the mower and Flex-
Arm to determine the cause of the noise or vibration and repair the abnormality.
DANGER!
DANGER!
Do not let the Blades turn when the Mower deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the cutting blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown
from the blades. (SRM-7)
Do not put hands or feet under Mower decks. Blade contact can result
in serious injury or even death.(SGM-9)
10.4 PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended
speed for efficient mower performance is between 2 and 5 mph. Operate the mower at its full rated PTO speed
to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for
the engine speed and gear to provide the required PTO and desired ground speed. Make sure that the mower
is operating at its full rated speed before entering the vegetation to be cut. If it becomes necessary to temporarily
OPERATION
regulate engine speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator
may be required to experiment with several gear range combinations to determine the best gear and range
which provides the most ideal performance from the mower and most efficient tractor operation. As the severity
of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to maintain the
proper operating PTO speed.
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death.(SG-26)
Mow at the speed that you can safely operate and control the Tractor and Mower. Safe
mowing speed depends on terrain condition and grass type, density, and height of cut.
Normal ground speed range is from 2 to 5 mph. Use slow mowing speeds when operating
on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when
debris and foreign objects are to be avoided. (SGM-7)
Operation Section 4-30
OPERATION
10.5 Operating the Flex Arm & Mower
When ready for field use, stop the cutter and pull the transport pins on the cylinder guard and the rotary cutter.
Lower the wings and cutter before entering the ditch. Drive the tractor forward along the side of the road and extend
the flex arm cylinder to ease the cutter into the ditch. Engage the PTO. Only operate the Flex-Arm and mower from
the tractor operator’s seat with the seatbelt securely fastened. The tractor must be equipped with a ROPS in the
raised position or a ROPS cab.
Before engaging the PTO the operator needs to make
sure that the blades are rotating in the correct direction.
If they are not they need to contact there local dealer
or Schulte to correct the problem. Refer to your operators
manual for proper blade rotation.
IMPORTANT: The operator should never operate the
mower with the Flex Arm if the blades do not have the
proper blade rotation. Serious injury or even death may
occur if cutter is operated.
The mower is designed to cut vegetation up to 2” in diameter . Sharp blades will produce a cleaner cut and require
less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maint ain the
PTO operating speed to prevent overloading the Flex-Arm, mower , and tractor. When cutting on ditches use the
cylinder to avoid most obstacles. The tractor may be needed to maneuver around larger obstacles.The FLX15 can
swing the cutter 87” using the cylinder. The FLX10 gives 75”. Choose a driving pattern that provides the maximum
pass length and minimizes turning.
IMPORTANT: Do not operate the PTO with the flex arm in the transport position for extended periods of time.
This may cause driveline vibration and will accelerate universal joint wear.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same
height as the surrounding area. However a better cut is possible with the Flex-Arm. There is only a single caster
wheel in front of the cutter and it is ideally located to maximize quality of cut. Lower cutting heights in general will
also increase cutting performance.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access
areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in
reverse. The Flex-Arm attaches to the mower by means of a strut that does not allow the mower to pivot in relation
to the arm. Which allows the mower to be easily backed up. However when mowing in reverse, operate the tractor,
Flex-Arm, and mower at a reduced ground speed to ensure tractor, Flex-Arm, and mower control is maint ained.
WARNING!
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
Use extreme care when transporting the Flex Arm and mower on public highways and roads. The combination of
Flex Arm and mower is wider than the tractor . In transport position, the mower is of fset to the right of the tractor .
Allow ample clearance when transporting the tractor and implements to insure that they do not contact any
bystanders, signs, road structures, or other vehicles. Do not allow the trailing mower to go off the road shoulder at
high speed. This may cause implements to be unsteady and may cause a roller over , serious injury or even death
can occur.
WARNING!
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the Mower and use extreme care when mowing in reverse. Mow only at
a slow ground speed where you can safely operate and control the Tractor and Mower.
Never mow an area in the reverse direction that you have not inspected and removed
debris or foreign material. (SGM-8)
Follow these guidelines to reduce the risk of equipment and grass
fires while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accessible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive
slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip
clutches, and gearboxes. Periodically shut down the Tractor and
Mower and clean clippings and collected debris from the mower
deck. (SGM-12)
DANGER!
OPERATION
Never raise the mower entirely while the blades are
turning. If the mower must be raised higher than 12”
from ground level, disengage the tractor PTO and wait
for all mower rotation to come to a complete stop
before proceeding to raise the mower. NEVER raise
the mower wings while the blades are turning.
When turning, the angle between the tractor and mower
should not be so great that a clattering of the U-joints
occurs. Sharp turns can cause premature failure of
the joints and place pressure on the tractor PTO shaft
and could cause extensive mechanical damage to the
mower and tractor.
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards in front and to the sides of the Tractor and Mower. Make sure that you can clearly
see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power
lines, debris and foreign objects. If you are unable to clearly see this type of item discontinue
mowing. (SGM-1)
Stay alert and watch for trees, powerlines, post s, signs,
and all other overhead and ground obstructions while
you are mowing. Use extreme care to avoid hitting
these types of obstructions.
T o avoid most obst acles, use the cylinder to steer the
cutter. The FLX15 can swing the cutter 87” using the
cylinder. The FLX10 gives 75”. The tractor may be
needed to maneuver around larger obstacles.
When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position
mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt
which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear
or damage to these components. Blades contacting the ground may cause objects to be thrown out from under
the mower deck. Always avoid operating the mower at a height or position which may cause the blades to contact
the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade wear and
possible blade component failure.
Do not let the Blades turn when the Mower Deck is raised for
any reason, including clearance or for turning. Raising the
Mower deck exposes the Cutting Blades which creates a
potentially serious hazard and could cause serious injury or
even death from objects thrown from the Blades. (SRM-7)
To shut down the mower, first bring the tractor to a
complete stop. Then slow down the mower by
reducing the engine speed before disengaging the
PTO. Wait for all rotating motion to stop before
proceeding to drive or shut down the tractor.
Park the tractor on a level surface, place the
transmission in park or neutral and apply the parking
brake, lower the attached mower to the ground, shut
down the engine, remove the key, and wait for all
motion to come to a complete stop before exiting the
tractor.
11. DISCONNECTING FLEX-ARM & MOWER FROM THE TRACTOR
DANGER!
WARNING!
OPERATION
Before disconnecting the mower and flex arm, the PTO must be disengaged and blade rotation at a complete stop.
Move the mower and flex arm to a level storage location and lower the center section and both wings to the ground.
If the mower will be stored with the wings in the raised position, install both wing and center section transport pins.
If the mower is not resting securely on the ground, block the mower up securely before attempting to disconnect
it from the tractor.
Use extreme care to keep feet and hands out from under the mower and clear of any pinch points when disconnecting
the mower from the tractor.
Always shut the Tractor completely down, place the transmission in p ark, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and Tractor
hitches. (S3PT-15)
Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift
the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the
tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue
Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with
possible serious bodily injury or even death. (STI-4)
tractor should be completely shut down and
secured in position. Relieve hydraulic pressure by
moving the control levers back and forth several
times.
2. Lower the parking jack and raise the flex arm until
the tongue clevis is no longer resting on the tractor
drawbar and is supported solely by the jack. Make
sure the jack foot is securely resting at ground
level or securely supported by a block before raising
the flex arm.
3. Once the flex arm tongue is being supported entirely
by the jack, remove the hitch bolt, locknut, and
washers.
4. Remove the flex arm driveline from the tractor
PTO shaft. Place the driveline in its storage
bracket to prevent it from contacting mud or dirt
which can contaminate the universal joint
bearings and shorten the life of the driveline.
5. Remove the hydraulic hoses from the tractor and
secure to the flex-arm to prevent contact with dirt.
6. After the driveline has been removed from the
tractor, place the PT O master shield back in the
operating position.
Driveline Storage
Support
OPERATION
12. FLEX-ARM & MOWER STORAGE
It is recommended that the mower be stored with the center section and both wings fully lowered to ground level.
If the mower is stored with the wings in the raised position, select a level area and install wing transport lock pins
to prevent the wings from falling BEFORE disconnecting the mower hitch and hydraulic hoses from the flex arm.
Store the mower with the center section transport lock pin inst alled or with the mower fully lowered. Never store
the mower with the center section or a raised wing supported by hydraulic pressure.
Properly preparing and storing the flex arm & mower at the end of the season is critical to maintaining its
appearance and to help ensure years of dependable service. The following are suggested storage procedures:
1. Thoroughly clean all debris off the flex arm & mower
to prevent damage from rotting grass and standing
water.
2. Lubricate all flex arm & mower grease points and
fill gearbox oil levels as detailed in the maintenance
section.
3. Tighten all bolts and pins to the recommended
torque.
4. Check the flex arm & mower for worn and damaged
parts. Perform repairs and make replacements
immediately so that the flex arm & mower will be
ready for use at the start of the next season.
5. Store the flex arm & mower in a clean, dry place
with the flex arm frame & mower housing resting
securely on blocks or at ground level.
6. Keep the drivelines yokes from sitting in water, dirt
and other contaminants.
7. Use spray touch-up enamel where necessary to
prevent rust and maintain the appearance of the
flex arm & mower.
DANGER!
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid flex arm
OPERATION
,mower, and tractor damage. If the flex arm & mower sit outside for an extended period of time or are exposed
to rain and/or humid air, the clutch lining plates must be inspected to ensure they are not frozen together
from rust or corrosion. If the flex arm & mower have been exposed to such conditions, at the start of each
mowing season, and any time it is suspected that the slip clutch plates may be frozen together, readjust the
slip clutch as explained in the maintenance section of the rotary cutter manual.
Never allow children to play on or around the Tractor and Implement. Children can slip or
fall off the Equipment and be injured or killed. Children can cause the Implement to shift or
fall crushing themselves and others. (SG-25)
13. TRANSPORTING THE TRACTOR, FLEX-ARM, AND MOWER
Inherent dangers of operating the tractor,flex arm, and mower and the possibility of accidents are not lef t behind
when you finish mowing an area. Therefore, the operator must employ good judgement and safe operation practices
when transporting the tractor, flex arm, and mower between locations. By using good judgement and following
safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized.
DANGER!
Never allow children or other persons to ride on the Tractor or
Implement. Falling off can result in serious injury or death.
Before transporting the tractor, flexarm,and mower , idle
the tractor engine, disengage the PTO. Fully retract
the flex arm cylinder and ease the cutter out of the
ditch as the tractor continues forward. With the
implement on a level surface,and all moving parts are
at a complete stop raise the cutter into transport
position. Insert the transport pins in the cylinder guard
on the flex arm and in wings of cutter. Also when
transporting, only raise the center deck enough to clear
ground obstacles to prevent tipping, especially when
traveling through rough terrain.
If the tractor’s hydraulic pump is not independent of
the tractor PTO, or if the tractor PTO has to be run to
have hydraulic power, disconnect the mower driveline
from the tractor PTO output shaft. Secure the driveline
to the mower deck to prevent driveline damage or loss
during transport.
Before transporting the tractor on a public roadway or
boarding a trailer for transport, the tractor brake pedals
should be locked together. Locking the pedals ensures
that both wheels brake simultaneously while stopping,
especially when making an emergency stop.
Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the mower at speeds greater than
20 MPH.
OPERATION
Tires and Wheels
Laminated Sectional Tires are designed for conditions where puncture proof performance is required and the
mower will not be transported for long distances on roadways. Transport speed for laminated tires should not
exceed 20 MPH. Excessive speed can cause damage to the machine and tire sections.
Foam Filled used Airplane Tires are ideal for conditions where a puncture proof tire is needed and the mower is
frequently transported between locations.
Pneumatic Tires (used airplane or implement tires) are ideal for frequent long distance towing, however , they are
not puncture proof and are not recommended for mowing brushy areas or other conditions that could damage the
tires. Maximum airplane tire inflation pressure is 50 PSI, minimum inflation pressure is 40 PSI. Inflate
ribbed implement tires to manufacturer rated PSI as shown on the tire sidewall. DO NOT over-inflate.
Extreme caution should be used when transporting the tractor and mower on public roadways. The tractor must
be equipped with all required safety warning features including a SMV emblem and flashing warning lights to
alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers
and most drivers will not be looking out for you, therefore, you must look out for them. Check your side view
mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be
extremely cautious when the piece of equipment that you are towing is wider than the tractor tire width and/or
extends beyond your lane of the road.
Only tow the Implement behind a properly sized and equipped Tractor which exceeds the
weight of the Implement by at least 20%. DO NOT tow the Implement behind a truck or
other type of vehicle. Never tow the Implement and another Implement connected in
tandem. Never tow the Implement at speeds over 20 MPH. (STI-6)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When
transporting the Equipment use the Tractor flashing warning lights
and follow all local traffic regulations. (SG-6)
Make sure that a proper size safety tow chain is secured between the tractor, flex arm, and mower before entering
a public road. Transport the flex arm with cylinder guard transport pin engaged and mower with wing and center
section transport pins engaged. Do not transport the mower supported by hydraulic pressure.
OPERATION
Practice steering and transporting the tractor, Flex Arm, and mower in an open parking lot before transporting on
public roads. Use extreme care when backing the equipment. The mower will not react to backing in the same
manner as it does when the mower is connected directly to the tractor. Practice backing until you can safely
control the direction and movements of the Flex Arm and mower . If you do not feel that you can safely transport or
back the equipment combination do not transport the equipment on public roads and highways.
Transport at slower speeds than you would normally transport the tractor (70% of normal transport speed). Allow
yourself more time to react adjust and compensate for the wider equipment. This equipment will trail behind you
like two implements one behind the other. Small turns or sideways movements of the tractor can cause the trailing
mower to move a greater distance to the side.
Use extreme care when transporting the Flex Arm and mower on public highways and roads. The combination of
Flex Arm and mower is wider than the tractor . It is also much longer than a single implement attached to the tractor
and you need to allow additional turning clearance. In transport position, the mower is offset 3’ to the right of the
tractor. Allow ample clearance when transporting the tractor and implements to insure that they do not contact
any bystanders, signs, road structures, or other vehicles.
The SMV (Slow-Moving Vehicle) emblem is universal
symbol used to alert drivers of the presence of
equipment traveling on roadways at a slow speed.
SMV signs are a triangular bright orange with reflective
red trim for both easy day and night visibility. Make
sure the SMV sign is clean and visible from the rear
of the unit before transporting the tractor, flex arm, and
mower on a public roadway . Replace the SMV emblem
if faded, damaged, or no longer reflective.
Make sure that all tractor flashing warning lights, headlights, and brake/taillights are functioning properly before
proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals and
operating lighting, most older models were only equipped with operating lights. Consult an authorized tractor
dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
When operating on public roads, have consideration
for other road users. Pull to the side of the road
occasionally to allow all following traffic to pass. Reduce
transport speed when traveling close to road shoulder
to avoid Flex Arm and cutter from being unstable or
possible roll over if mower wheels go off the shoulder.
Do not exceed the legal speed limit set in your country
for agricultural tractors. Always stay alert when
transporting the tractor, flex arm, and mower on public
roads. Use caution and reduce speed if other vehicles
or pedestrians are in the area.
DANGER!
This Implement is wider than the Tractor. Be careful when operating
or transporting this equipment to prevent the Implement from running
into or striking sign posts, guard rails, concrete abutments or other
solid objects. Such an impact could cause the Implement and Tractor
to pivot violently resulting in loss of steering control, serious injury, or
even death. Never allow the Implement to contact obstacles. (S3PT-
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
Operation Section 4-39
OPERATION
Reduce speed before turning or applying the brakes.
Ensure that both brake pedals are locked together
when operating on public roads.
DANGER!
In the transport position the flex arm offsets the mower as much as 3’ to the right. Do not allow the trailing mower
wheels to run off the edge of the road or shoulder . Sudden turns or running off the road can cause loss of stability
and possible mower and tractor roll over resulting in serious bodily injury or even death.
DANGER!
WARNING!
OPERATION
When the Wings are folded for transport, the center of gravity is raised
and the possibility of overturn is increased. Drive slowly and use
extremecaution when turning on hillsides. Overturning the Implement
could cause the Implement to overturn the Tractor and vice versa resulting
in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn. (STI-2)
Be particularly careful when transporting the Implement using the tractor.
Turn curves or go up or down hills only at a low speed and at a gradual
steering angle. Make certain that at least 20% of the tractor’s weight is
on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces.(STI-1)
Only tow the Implement behind a properly sized and equipped Tractor which exceeds the weight
of the Implement by at least 20%. DO NOT tow the Implement behind a truck or other type of
vehicle. Never tow the Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-6)
WARNING!
When transporting the implements reduce speed when going around corners. Do not make any sudden turns at a
high transport speed. The tractors and implements are much longer so turning speed needs to be at a low speed,
and more clearance need to be taken in account for when turning.
Secure the Implement for transport before traveling on public roads. For pull-type Implements,
secure the center axle using cylinder stops or transport pin and properly attach a safety chain
between the Implement and Tractor. Secure wings in upright position on folding Implements
using wing transport locks. (STI-7)
Operation Section 4-40
OPERATION
WARNING!
Transport only at safe speeds. Serious accident s and injuries can
result from operating this equipment at unsafe speeds. Understand
the Tractor and Implement and how it handles before transporting
on streets and highways. Make sure the T ractor steering and brakes
are in good condition and operate properly.
Before transporting the Tractor and Implement, determine the safe
transport speeds for you and the equipment. Make sure you abide
by the following rules:
1. Test the tractor at a slow speed and increase the speed
slowly. Apply the Brakes smoothly to determine the
stopping characteristics of the Tractor and Implement. As
you increase the speed of the Tractor the stopping dist ance
increases. Determine the maximum safe transport speed
for you and this Equipment.
2. Test the equipment at a slow speed in turns. Increase the
speed through the turn only after you determine that it is
safe to operate at a higher speed. Use extreme care and
reduce your speed when turning sharply to prevent the
tractor and implement from turning over. Determine the
maximum safe turning speed for you and this equipment
before operating on roads or uneven ground.
OPERATION
3. Only transport the Tractor and Implement at the speeds that
you have determined are safe and which allow you to
properly control the equipment.
Be aware of the operating conditions. Do not operate the Tractor
with weak or faulty brakes. When operating down a hill or on wet
or rain slick roads, the braking distance increases: use extreme
care and reduce your speed. When operating in traffic always
use the Tractor’s flashing warning lights and reduce your speed.
Be aware of traffic around you and watch out for the other guy . (SG-
19)
13.2 Hauling the Tractor, Flex Arm and Mower
The Flex Arm and the mower must be disconnected and separated before loading onto a trailer. Follow the
instructions and safety precautions listed in this manual to disconnect and separated the mower from the Flex
Arm.
Do not attempt to transport an over width load with out obtaining proper licenses and permits from your state
transportation offices.
Before transporting a loaded tractor, flex arm, and mower , measure the height and width dimensions and gross
weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas
that will be traveled through.
Use adequately sized and rated trailers and equipment to transport the tractor, flex arm, and mower . Consult an
authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty straps,
cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie down locations
as specified by the tractor manufacturer.
Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully
tighten the securing chains or other fasteners used as much as possible using boomers or binders to apply
maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension
involved when released has the potential to inflict serious injury .
While hauling the tractor, flex arm, and mower, make occasional stops to check that the tractor, flex arm and
mower have not moved or shifted and that the securing chains have maintained tension. If during transport a hard
braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of
the load.
1. Check all nuts and bolts for tightness after the first 8 hours of operation, then weekly. Check the condition
of cotter pins, roll pins and other fasteners weekly and replace if necessary.
2. Castor cone spring tension nuts
Two back to back cone springs are used to keep the castor assemblies tight and reduce castor whipping
action. The double jam nuts that are used to lock the castor assembly in place may need to be adjusted in
order to take up wear in components of the castor pivot.
The lower nut should be adjusted to the point that the cone springs are flattened, and then it should be backed
off one half turn. Next, the lower nut should be held with a wrench so it does not change its position, while the
upper nut is tightened down onto it.
3. Bolt Grades and Torque
When replacing damaged bolts use only plated Grade 5 bolts unless otherwise specified. Use only
bolts of the correct length [Refer to the "Parts" section]. Do not replace lock nuts with nuts and lock
washers. Use only original equipment lock nuts.
Recommended Torques in foot pounds for SAE Grade 5 bolts, based on dry assembly:
1.1 Tires
Periodically check tire pressure. The standard aircraft tire should be inflated to 40 PSI.
MAINTENANCE
1.2 Steady Bearing Locking Collar
The shaft and collar must be free of paint and burrs.
Remove the tractor shaft and front bell assembly.
Insert a punch into the hole provided on the locking collar and tap the
punch so that the collar turns in an anti- clockwise direction when
facing the front of the collar. (The locking collar must be locked down
in the same direction as the direction of shaft rotation.)
Tighten down the set screw. (We recommend using Lock-tite on the
set screw threads)
It is recommended that hubs are dismantled, cleaned and repacked every year. Use the diagram and
following instructions for maintaining the wheel hubs. Whenever a worn or damaged seal is replaced
the bearing assembly should be cleaned and repacked with a good grade of wheel grease.
WARNING!
Always read carefully and comply fully with the manufacturers
instructions when handling oil, solvents, cleansers, and any other
chemical agent.

2. Pack the inside of the hub with grease. Grease needs to cover complete surface area inside hub
but does not need to fill cavity.
3. Smear grease on both races.
4. Install the large bearing into the back of the hub and rotate the bearing several times.
5. Install the dust/grease seal using the right size seal driver. Spread a film of grease on the dust
seal rubber and on the axle where the seal fits.
6. Position the hub on the axle and firmly push into place then pull hub towards you about 1".
Slowly rotate hub while gently pushing the hub back onto the axle.
7. Check dust seal to ensure seal rubber is positioned correctly.
8. Install the small or outer bearing..
9. Install the axle washer and castle nut on the axle.
Proper Settings for the tapered roller bearings is described in the following procedure. Always use a new cotter
pin when making adjustments to the hubs.
1. Tighten the castle nut to 20 foot pounds while turning hub. Then back the nut off 1/2 of a turn. Spin the hub
2 or 3 times. While slowly turning hub clockwise, hand tighten the castle nut until castle nut notch lines up with
hole in axle. If notch will not line up, back off nut to next notch.
2. Put the cotter pin in the axle hole. Before bending the cotter pin spin the hub. The hub should free wheel
from 1 to 2 full turns.
3. If the hub soins the right amount, finish installing the cotter pin by bending the ends.
4. Coat the inside of the dust cap with a thin coat of grease by using your gloved finger. Then install on hub
using the right dust cap driver.
5. Wipe off all excess grease from hub and axle.
IMPORTANT: There should not be any drage noticed when spinning a tire installed on a hub. If the
axle nut is too tight, the rollers of the wheel bearings will remove the grease from the bearing races,
decreasing the life of the bearings.
2.2 Hydraulics
Periodically clean dirt and debris from the bottom side
of the depth stop ring.
Inspect hydraulic hoses, fitting and cylinders for wear
or leaks. Use a piece of cardboard or wood rather than
hands to search for suspected leaks. Replace if
necessary.
Before applying pressure to the hydraulic system, be
sure all connections are tight and that the hoses are
not damaged.
MAINTENANCE
DANGER!
Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard.
High-pressure oil streams from breaks in the line could penetrate the
skin and cause tissue damage including gangrene. If oil does
penetrate the skin, have the injury treated immediately by a physician
knowledgeable and skilled in this procedure. (SG-15)
Replace oil in gearboxes after the first 50 hours of operation then yearly.
Check gearbox oil level frequently. Steady loss of oil will indicate damaged seals, which should be
replaced immediately to prevent ruining the gearbox.
Procedure for refilling of gearboxes:
-A dip stick is provided on the vent plug. Fill until oil shows on the dipstick. Do not screw
dipstick in when checking oil level.
WARNING!
DIP STICK
FILL LINE
-Use of an oil/grease pump to suck oil out of the gearbox is recommended to minimize
spilled oil and to provide for more complete removal of old oil.
2. Gear case oil should meet the following specifications:
-API Service Classifications GL-5
-Military Specification MIL-L-2105C
Consult the following chart for the oil viscosity recommendations:
WHEN FILLING RIGHT ANGLE DRIVES
ALLOW APPROX. 15 MIN. FOR OIL TO
SETTLE INTO BOTTOM CAVITY BEFORE
CHECKING DIPSTICK.
-Type of Grease: A good quality NLGI #2 EP grease, lithium soap base should be used to grease
the needle bearings in cross journals, shield bearings, telescoping members and CV
centeringmechanism. For heavy duty applications a compatible grease with 3 to 5% molybdenum
disulfide additive may be used.
-Cross Journals: Every 8 hours.
Lubricate until grease purges from underneath all four needle bearing caps.
-Shield Retaining Bearings: Every 8 hours.
The shield bearings are greased by a fitting molded into the shielding bell. Three pumps are
required.
IMPORTANT: Check that the driveline shielding is not damaged and rotates freely on the driveline.
-Constant Velocity Body: Every 4 hours.
The housing for the CV body serves as a reservoir for the lubrication of the centering mechanism.
Approximately 30 pumps are required every 4 hours.
-Telescoping Tubes: Every 4 hours. Apply grease to the collar located at the middle of the shaft.
The grease fitting on this collar will come exposed when the cutter wings are laying flat.
Occasionally (monthly) pull the universal joint halves apart and apply grease to all sides of the slip
shaft. At least once per year (more often in dusty or dirty conditions) the shielding should be
removed and the old grease removed with a solvent. A fresh coat of grease should then be
applied to the entire surface of the inner tube.
IMPORTANT: If the universal joint sliding members are allowed to dry out to the point where two
halves cannot slip freely, damage to the rotary cutter or tractor may occur.
CAUTION!
Always wear protective gloves when handling grease.
2.5 Frame
NLGI #2 EP molybdenum disulfide fortified grease is preferred for all sliding contact type applications such as
frame pins.
MAINTENANCE
Frame pivot points: Daily during the first week of usage, and every 50 hours of operation thereafter, 16 locations:
(1) Hitch clevis, swivel
(1) Hitch frame, main pivot
(2) Steady bearing stand
(1) Arm link
(1) Gearbox mounting stand, main pivot
(1) Gearbox mounting stand, link

(2) Hitch tongue – cross pin grease zerk is on bottom side of sleeve
Hoses and breakaways are provided in order to connect to a 15’ rotary cutter with individual single acting wing
circuits. A total of 4 hydraulic circuits are required. Two of the circuits require float positions on the control
valves in order to operate the single acting wing circuits on the rotary cutter.
FLX10 Hydraulic Circuit Requirements
Hoses and breakaways are provided in order to connect to a 10’ rotary cutter with single acting wing circuit. A
total of 3 hydraulic circuits are required. One of the circuits requires a float position on the control valve in
order to operate the single acting wing circuit of the rotary cutter.
Solenoid Valve Kit
An optional solenoid valve kit is available for the FLX15 and FLX10 to reduce the number of tractor circuits
require to operate the FLX15, from 4 to 3 circuits, and the FLX10, from 3 to 2 circuits.
The kit includes additional hoses and breakaways in order to operate the wing lift cylinders in double acting
mode and does not require a float position on the tractor control valves.
1. Replacement cylinder head and butt seals must be available before beginning disassembly as they
will be damaged during the procedure. The piston seal may also be subject to damage during
disassembly.
2 Secure the cylinder snugly in a vice. Do not over tighten the vice or the barrel will compress.
3. Locate the slots at either end of the barrel. The cylinder head will be removed first.
4. Using a thin blade screwdriver, insert the blade into the end of the slot near the cylinder head and pry
the retaining wire up slightly.
5. With the screwdriver under the wire, rotate the cylinder head to thread the wire out. The cylinder
head can be turned with a pin wrench in the holes provided, with a pipe wrench, or with a strap wrench.
6. Thread the wire completely out of the barrel. Note which hole in the cylinder head that the wire was
inserted in (there are 4 holes in the cylinder head. When reinstalling the cylinder head, the wire must
be inserted in the same hole and the wire must be installed in the opposite rotation from removal (ie. If
the cylinder head was turned clockwise to remove the wire, it must be turned counterclockwise for
installation). This will ensure correct port orientation.
MAINTENANCE
7. With the cylinder head wire completely removed, disassembly can continue. Ensure that the ports
at both ends of the cylinder are open to the atmosphere. Insert a long pin or a bar thru the pin hole on
the shaft mount. Use this bar to fully extend the shaft. A hard pull should dislodge the cylinder head
from the barrel.
8. Continue to pull on the shaft until the o-ring on the cylinder head becomes lodged in the slot in the
barrel. Insert a knife in the slot and cut the o-ring and back up seal. These seals can be threaded out
thru the slot in the barrel.
9. Continue to pull on the shaft. The cylinder head, piston and shaft will pull free from the barrel.
10. If the seal at the butt end of the cylinder needs to be replaced, disassembly is the same as for the
cylinder head (see steps #3, 4 and 5). Again, note the rotation used to remove the wire and use the
opposite rotation for assembly. There is only one wire hole in the butt.
11. To remove the piston nut, do not clamp the shaft in a vice as it may be damaged. Locate a pin that
will fit nicely thru the shaft clevis. Insert the pin vertically in a vice and tighten it securely. Insert the
shaft clevis over the pin.
12. Remove the piston nut. The piston and cylinder head can now be removed.
13. Inspect all components for wear and scoring. Closely inspect the bore of the barrel for scoring or
wear marks. Check the shaft closely for wear marks, scoring, pitting or rust (discoloration of nitrosteel
shafts is normal). Check the bore of the cylinder head for wear marks, scoring and rust. Check the
outside diameter of the piston for wear marks or scoring. Check seals for wear, nicks, tearing or other
damage.
14. Replace all damaged components. It is recommended that all seals be replaced, even if there is no
visible damage.
15. Assembly is the opposite of disassembly. Use a small amount of oil to lubricate all seals prior to
assembly. Caution must be used to prevent seal damage.
