In order to reduce accidents and enhance the safe operation of mowers, Alamo Industrial, in cooperation
with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower
Safety Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial
and agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the
mower, will significantly assist in this important education.
Your Authorized Alamo Industrial Dealer may have shown this video and presented you a DVD Video
when you purchased your mower. If you or any mower operator have not seen this video, Watch the
Video,Read this Operator’s Manual, and Complete the Video Guidebook before operating your new
mower. If you do not understand any of the instructions included in the video or operator’s manual or if
you have any questions concerning safety of operation, contact your supervisor, dealer or Alamo Indus-trial.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax
AEM VHS Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to
AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please
include your name, mailing address, mower model and serial number.

Operator Safety Instructions and Practices
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.
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service.
(SG-31)
“Wait a minute...Save a life!”
(S3PT-19)
(S3PT-10)
SAFETY
ever operate the Tractor or Implement un
you have read and completely understand this Manual, the Tractor Operator’s Manual, and each
of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency.
Never allow inexperienced or untrained personnel to operate the Tractor
and Implement without supervision. Make sure the operator has fully
read and understood the manuals prior to operation.
(SG-4)
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 that may be thrown by
the equipment.
(SG-16)
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.

instructions when handling oil, solvents, cleansers, and any other
chemical agent.
(SG-22)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death.
(SG-24)
Never allow children to play on or around Tractor or 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 or others.
(SG-25)
NEVER use drugs or alcohol immediately before or while operating the
Tractor and Implement. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or
Implement, an operator on prescription or over-the-counter medication
must consult a medical professional regarding any side effects of the
medication that would hinder their ability to operate the Equipment safely.
NEVER knowingly allow anyone to operate this equipment when their
alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of
drugs or alcohol.
(SG-27)
onged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation.
se extreme caution when ge
ng onto the Implement to perform repairs, maintenance an
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death.
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and
hose connections. Relieve hydraulic pressure before performing maintenance or repairs.
Use gloves and eye protection when servicing hot components. Contact with a hot surface
or fluid can cause serious injury from burns or scalding.
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
(SG-36)
Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection
when servicing hot components. Contact with a hot surface or fluid can cause serious injury
from burns or scalding.
(SG-38)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up.
(SGM-09)
Always keep a careful lookout and use extreme care when working around utility and
municipal obstructions. Never allow the Mower to contact any utility, municipal, or other
type structure. Clearly mark all mowing obstructions and consult local utility providers for
a safe code of operation.
(SPU-5)
Do not operate the implement while wearing loose fitting clothing. Entanglement of th
clothing with the rotating elements can result in serious injury or even death. Stay clear o
all rotating elements at all times. (SSP-03)
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted
position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop
of unit with injury or death by crushing. To properly park the implement when disconnecting
it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure
support under the A-Frame. Lower the implement carefully to the ground. Do not put hands
or feet under lifted components.
(S3PT-1)
SAFETY
se extreme care when lowering or unfo
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-05)
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.
e sure you have adequate knowledge of the property you w
e working on. Take time to
make yourself aware of any area underground lines or cables. Contact with buried lines o
cable could result in serious injury or death. If in doubt about buried utility lines call 811
before digging or 1-800-258-0808.
(SBH-6)
Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately. Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with
excessive vibration can result in component failure and 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 Mower to be operated with blades missing.
(SFL-4)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective 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)
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only.
(SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily.
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped.
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions.
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use Cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure.
(SG-13)
(SG-15)
SAFETY
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health.
(SG-23)
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)
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death.
n case of mechanical
ng operation, place the transmission in the par
(SG-29)
position, set the parking brake, shut down all power, including the PTO and the engine and
remove the key. Wait until all rotating motion has stopped before dismounting.
Do Not operate this equipment in areas where insects such as bees may attack you and/or
cause you to lose control of the equipment. If you must enter in such areas, use a tractor
with an enclosed Cab and close the windows to prevent insects from entering. If a tractor
cab is not available, wear suitable clothing including head, face, and hand protection to
shield you from the insects. Attacking insects can cause you to lose control of the tractor,
which can result in serious injury or death to you or bystanders. Never dismount a moving
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(90 m) 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 these 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.
(SG-40)
(SGM-1)
(SGM-02)
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.
reme care should be taken when operating near loose objects suc
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-05)
any 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.
ow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). 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.
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-08)
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:
(SGM-07)
SAFETY
-Equip the Tractor with a fire extinguisher in an accesible 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)
ower is designed for certain mowing applications and is rated to cut up to a spec
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 nonvegetative 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)
Do not operate or pull the mower into standing water. When uplift or fan type mower blades
contact water they can be severely deflected downward causing possible failure of blade
resulting in serious boldly injury to the operator or bystanders.
Use extreme caution when raising the Mower above ground level. Stop the Blades from
turning when the Mower is raised and passersby are within 100 yards. Raising the
Mower exposes the Cutting Blades which creates a potentially serious hazard and can
cause serious injury by objects thrown from the Blades or by contact with the Blades.
Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet 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;
SAFETY
-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.
(SPU-1)
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 required to mow, reduce
wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and
make the final cut more uniform).
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.
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.
Connecting or Disconnecting Implement Safety Instructions and Practices
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 Implement resulting in
excessive vibration, thrown objects, and blade and implement 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)
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.
Never operate the Tractor and Mower if the Implement input 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 disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-15)
(S3PT-16)
SAFETY
en attaching the Implement input driveline to the Tractor
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.
Before operating the Implement, 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
driveline can cause personal injury.
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go
up hills only at a low speed and using a gradual steering angle. Rear mounted implements
move the center of gravity to the rear and remove weight from the front wheels. Make
certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels
to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough o
uneven surfaces to prevent loss of steering control which could result in property damage
or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched
transport position. Dropping implement in transport can cause serious damage to the
tractor and/or Implement and possibly cause the operator or others to be injured or killed.
(S3PT-02)
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
SAFETY
solid object while turning will cause equipment damage and possible injury.
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.
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high speeds. Understand the Tractor and Implement 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 Implement, determine the proper transport speeds for
you and the equipment. Make sure you abide by the following rules:
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 distance increases. Determine the maximum
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after
you determine that the equipment can be operated 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 turning speed for you and this equipment before
operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control
the equipment.
SAFETY
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes
or worn tires. 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.
e 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.
ow 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.

Maintenance and Service Safety Instructions and Practices
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.
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.
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.
Always maintain the safety signs in good readable condition. If the safety signs are missing,
damaged, or unreadable, obtain and install replacement safety signs immediately.
Do not modify or alter this Implement. Do not permit anyone to modify or alter this
Implement, any of its components or any Implement function.
(S3PT-09)
(S3PT-11)
(SG-5)
(SG-8)
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)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running.
(SG-20)
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have

This section is intended to explain in broad terms the concept and effect of federal laws and regulations
concerning employer and employee equipment operators. This section is not intended as a legal
interpretation of the law and should not be considered as such.
Employer-Employee Operator Regulations
U.S. Public Law 91-596 (The Williams-Steiger Occupational and Health Act of 1970) OSHA
This Act Seeks:
“...to assure so far as possible every working man and woman in the nation safe and healthful working
conditions and to preserve our human resources...”
DUTIES

Child Labor Under 16 Years of Age
Some regulations specify that no one under the age of 16 may operate power machinery. It is your
responsibility to know what these regulations are in your own area or situation. (Refer to U.S. Dept. of
Labor, Employment Standard Administration, Wage & Home Division, Child Labor Bulletin #102.)
Made for use with smaller tractors in the 35 HP range, the rear mounted PA92 is your first choice when you
have the need to get in those hard to reach areas such as ditches and culverts to take care of light duty
vegetation. Stretch around waterways or ponds or mow along the roadside with ease. Grounds and roadway
maintenance is simplified when you have this boom on your team.
The PA92 mounts to the rear of the tractor utilizing a 3-point hitch. This allows for ease of disconnect and
convenient storage on a jackstand when not in use.
The controls are located at the operator’s fingertips. These cable controls are connected to the hydraulic
system located away from the driver in case of hose failure.
The boom arms are two-piece and use parallel linkage. These strong arms are made of A50 grade square
steel tubing. All of the hydraulic systems; pumps, hoses and connections are strategically placed to prevent
damage from obstacles such as fencing tree-limbs, etc. Boom reach is approximately 14’ when fully extended.
A hydraulic lift cylinder is strategically placed for maximum clearance when boom is fully extended.
A self-contained hydraulic system bypasses utilizing tractor hydraulics which allows for use on smaller tractors
with a minimum of 35 HP.
The 48” flail head is also available for areas that need a precise cut such as parks, playgrounds, and school
grounds.

These hydraulically driven mowers are designed for light-duty work. They can mow pastures and control grass
and weeds on highways or industrial sites.
For Non-Agricultural use, OSHA, ASAE, SAE and ANSI standards require the use of Chain
Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly
recommends the use of Chain Guards, Deflectors, or Solid Skirts for Agricultural purposes
as well to reduce the risk of property damage, serious bodily injury, or even death from
objects thrown out by or from contact with the Cutting Blades.
At least 20% of the tractor’s total weight must be on the front tires with the Mower lifted to
provide adequate traction for safe steering under good conditions. Slow down on hills, rough
terrain, and curves.

3. Record the Mower Model and Serial Numbers on the Warranty page at the end of the Operator’s Manual.
Keep this as part of the permanent maintenance file for the Mower.
The Power Arm 92 fit almost any tractor with a Category II linkage.
Linkage Isolation
Although it may be possible to operate the semi-independent version of the PA92 without linkage isolation, a
severe strain would be put upon the attachment yoke and pins. Most modern tractors are equipped with a
ready means of providing linkage isolation through a conveniently operated valve.
Linkage isolation is not required on the fully independent model of the PA92 and the tractors hydraulic controls
should be neutralized.
Check Chains/ Stabilizers
To hold the machine firmly in position, check chains or stabilizer bars must be fitted. It is dangerous to operate
the machine without these elements.
Tractor Relief Valve
ASSEMBLY
The main relief valve in the hedger hydraulic control unit is set at 1800 PSI (140 Bar). Therefore, if operating
the PA92 in semi-independent form, the tractor’s relief valve setting must be at least a little above 1800 PSI for
satisfactory operation.
Tractor Hydraulic Flow Rates
Oil flow rates are not crucial when operating a semi-independent PA92. Flow rates of up to 10 GPM (45 1/min.)
should not have any adverse to the inching response that it is sometimes required from the control valve.
P.T.O. Shaft
Tractor must be equipped with live drive-independent PTO shaft to enable forward movement to be halted
while the flail head continues to operate.
Draft Control
Loads imposed through the draft sensing mechanism will not normally be sufficient to put a strain on the
tractor. However, any provision for draft control should be set to minimum response. Where a draft control
rocker is fitted with a dead pin this should be utilized.
A tractor fitted with a cab that has a safety glass windows should be used whenever possible. This is a basic
safety precaution applicable to the use of all flail-type hedge trimmers.
Power arms are supplied with an operator guard kit (Part No. 73 13 324) which must be fitted to the tractor
before commencing work.
ASSEMBLY
It consists of two areas of wire mesh which can be shaped to suit and be secured against the cab window with
a spring loaded hooks; the upper edge being anchored around the cab gutter and the lower edge around the
mudwing.
According to the great range of cabs, it may be necessary to adapt or make brackets to secure the mesh.
If the flail is operated on a tractor that is equipped with a a safety frame or roll bar only, an additional frame
must be made and fixed to the tractor onto which the guard mesh can be secured. In addition to the guard
mesh, a sheet of Polycarbonate transparent glazing must be fitted to the frame to provide further operator
protection. This material must also be used when the cab does not have safety glass installed.
The operator guard kit supplied is suitable for all standard applications; i.e., rear mounted on a conventional
tractor. For other applications, additional mesh guarding may need to be constructed to give adequate operator
protection. A guideline to follow when assessing any additional guarding that may be required is that the
operator must always be looking at the flail head through the mesh when it is in any working position.
Polycarbonate transparent sheeting is an impact resistant material which can be readily sawed and shaped
according to requirements. Unfortunately, it is susceptible to surface damage and scratching. Therefore, it is
advisable to place the material on the inside of the window for protection. No attempt should be made to wipe
the sheeting with dirt ingrained cloth.
Toughened grades of polycarbonate sheeting are available under the brand names of “Makrolon”, “Tuffak” and
“Lexan”.
In case of difficulty in obtaining this material locally, contact F.W. McConnell Ltd. through your normal dealer.
Tractor must be stable while operating the hedge cutters under all conditions. Pay attention when operating on
slopes. Front end ballast as well as rear wheel weights to counterbalance the overhang of the flail head should
be added as appropriate. On steeply banked ground, it may not be sufficient to depend alone on the
counterweight provided by the oil reservoir.
In addition, rear wheel track should be set as wide as possible to increase stability. It will also increase the
protection to the reservoir.
JOHN DEERE CONVERSION KIT (81- 30- 059) for Si Models
ASSEMBLY
The John Deere utilizes a “closed center” hydraulic principle and because of this, it is necessary to modify
either the tractor’s external oil supply or the flails main control valve.
There are the following two alternatives.
1. A flow limiting valve manufactured by John Deere is available to provide an “open center” external supply.
For further advice consult your John Deere dealer.
2. A control valve conversion kit (Part No. 81-30-059) consists of a relief valve blanking plug which should be
installed in place of the existing relief valve and a pressure gallery blanking plug which is installed in place of
the standard blanking plug at the valve outlet end next to the lift ram gland connection.
Be careful when extracting the relief valve not to damage the copper sealing washer as it is reused.
When working in this mode, the tractor’s pressure control valve must not exceed 2500 PSI (170 Bar).
1. The machine is delivered in a partially dismantled condition. To make ready for attachment to the tractor it
will be necessary to select a hard level surface
2. Cut the banding straps and remove the attached articles.
3. Fill the reservoir to capacity with oil selected from the chart on Section 3-9 to increase the stability of the
machine.
4. Remove and discard the transport strap connecting the flail head to the frame and also the lift ram stop
strapped to the rod.
ATTACHMENT TO TRACTOR
Si Model
*On Si model, reverse the tractor up as closely as possible and connect the return and supply hoses to the
tractor. Fit suitable return connection to the tractor and connect the return hose before connecting the supply
hose to the tractors external services point with a suitable self seal coupling.
1. Ensure the lift ram tap is fully open.
*With the aid of a crowbar prise the flail head sideways until there is sufficient clearance to allow the tractor to
be driven up and the draft links connected. Assistance will be needed to simultaneously select “Reach out” and
“Angle down” to allow the oil to flow while the arms are being moved.
As a safety precaution, to prevent the possibility of the flail head slipping sideways and the
arm collapsing on the fitter as the head is pried sideways, a loop of strong rope or wire with
sufficient slack to allow the required flail head movement should connect the frame and
dipper. This will then act as a stopper in the event of this happening. Leave in position until
attachment is complete.
2. Adjust tractor drop arms to enable the draft links to lower within 15 ins (375 mm) of the ground.
3. Remove the top link and machine yoke completely.
4. Reverse the tractor squarely to the front of the machine, engage draft link pins and secure.
5. Attach yoke to the top hitch position on the tractor ensuring the lug for the top link is uppermost.
6. Unlimber the machine controls from its storage position and lift into the tractor cab.
7. Install the top link between yoke and upper hitch position on the machine. If necessary, fitting CAT I
sleeves into the ball ends of the top link.
ASSEMBLY
*Raise the machine on its three point linkage to the working height, i.e. when the PTO shaft and the gearbox
stub shaft are (as near as possible) in a straight line.
Do not operate quadrant lever of machine controls through the rear cab window while
standing on or amongst linkage components. Always seek assistance.
*Measure the PTO drive shaft length as shown in diagram below and subtract 1 inch (25 mm.).
ASSEMBLY
*This measurement which is the fully closed final length of the PTO drive shaft measured button to button
should be taken carefully before the PTO drive shaft is shortened to suit by cutting off both the driving and
driven members of the tube by an equal amount. Likewise, the plastic shield will similarly have to be cut. Take
heed if too much is cut, it cannot be stuck back on. Measure twice and cut once. Accurate measurement is
important on some close coupled tractors to ensure maximum engagement during operation.
8. Lower the machine to the ground and fit the PTO shaft in position. Ensure that the collar locking devices on
the PTO shaft are fully engaged. Wrap the torque chain around the tractor drawbar or any convenient point
to prevent the shaft guard from rotating.
9. Raise the machine to working height.
10. Check that the rotor control valve is in the STOP position.
11. With PTO engaged on Ti model or with tractor external services activated on Si model, select “Lift Down”.
This will level the frame and enable the lower yoke pins to be fitted. Select the hole which will, as near as
possible position the PTO shaft horizontally in line.
12. Lower the quadrant lever so that the machines weight is taken by the yoke.
13. Adjust the top link to bring the pillar upright.
*Remove the rope arrestor loop.
14. Carry out final adjustment of the tractor lift arm leveling box to bring the main frame horizontal. This should
be checked with the arms at approximately half reach with the flail head clear of the ground.
15. Tighten up the check chains or adjustable stabilizers to hold the machine rigid without side-sway.
16. Remove the parking feet, turn inward 90 degrees and relocate in their housings.
17. Carefully operate the machine through its full range of movement while checking that the hoses are not
strained, pinched, chaffed or kinked and that all movements are functioning correctly.
*Assemble the front hood to the flail head.
18. Fold the machine into the transport position.
19. The machine is now ready to proceed to the work site.
This procedure is for initial attachment only, for subsequent attachment paragraphs marked * do not apply.
The 3 lever control unit which is cable operated is mounted on an adjustable stalk that is attached to a seat
bracket which is of universal design for mounting in many models of tractor. The bracket is normally trapped
between the seat runners and their mounting base. It may sometimes be necessary to drill extra holes in the
seat bracket to find the ideal operator position.
On tractors other than quiet cab models, the stalk can be bent and bolted to the mudwing or the cladding of the
cab ensuring no structural member of the safety frame is drilled.
ASSEMBLY
The control unit itself is bolted to an angled mounting bracket in either a transverse or longitudinal position thus
giving a variety of mounting position, which in conjunction with flexibility of the mounting pillar will enable a
satisfactory working position to be achieved.
Shown above is detail of alternative fitting of the mounting spigot. In deciding the final of the control box,
remember that tight bends in the cables will reduce their operational life. Do not exceed the minimum
acceptable bend radii of 8”.
The handles may be screwed into alternative holes in the levers to give an “in line” installation should it be
desirable.
The machine is delivered from the factory without oil. Fill the reservoir with a light hydraulic oil as
recommended in the chart until the oil level is approximately 2” below the top of the tank. The total capacity is
approximately 117 tires (25 gallons). Do not overfill. The oil must have anti-frothing characteristics suitable for
use in hydraulic systems.

3. Check the tractor rear axle oil level and top up if necessary.
4. Place the flail head at a safe position and bring tractor engine revolutions to 1000 RPM to avoid stalling
when the starting load is placed on the motor. Engage PTO and allow the rotor to run for several minutes.
Do not leave the tractor cab or allow anyone to approach the flail head at this time.
Do not allow the pump to continue working if the rotor does not turn. Overheating and
serious pump damage to the pump can be caused in a very short time.
5. After running up the machine, increase PTO speed to approximately 360 RPM. Run machine further for
five minutes before disengaging the PTO and stopping tractor. The reason for this running period under a
no load condition is to thoroughly circulate the oil in the reservoir through the return line filter.
6. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck
the oil level in the tank and top up as necessary.
1. Select a firm level site for parking the machine.
2. Remove the parking feet, turn through 90 degrees and relocate in their housings.
3. Unscrew the lift ram tap and with the machine at approximately half reach in normal working position, i.e.
not broken back. Operate the hydraulic services until the flail head roller is horizontal and level with the feet
of the main frame.
4. Disengage tractor PTO and remove.
5. Disconnect stabilizers bars or loosen check chains as applicable.
6. Unbolt the control unit from the mounting pillar, remove from tractor cab and stow in a suitable location
clear of the ground. On Si models only, the supply and return hoses must be disconnected from the tractor
and stowed with their ends covered and clear of the ground.
7. Raise the machine on the tractor’s linkage to take the weight off the yoke and remove the lower yoke pins.
8. Lower the tractor draft links and place machine firmly on the ground.
9. Remove draft links and top link from the machine, drive tractor away and remove yoke. Blank off the end of
the return hose with plug or small plastic bag if a self-seal coupling is not fitted.
Alamo Industrial flail mowers are manufactured with quality material by skilled workers. These mowers are
designed for cutting grass and small weeds. The mower is equipped with protective deflectors to prevent
objects being thrown from the mower by the blades, however, no shielding is 100% effective. All shields,
guards, and deflectors equipped on the mower must be maintained in good operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every
reasonable precaution to ensure oneself, others, animals, and property are not injured or damaged by the
mower, tractor, or a thrown object. Do not operate the mower if passersby, pets, livestock, or property are
within 100 yards of the unit.
This section of the Operator’s Manual is designed to familiarize, instruct, and educate safe and proper mower
use to the operator. Pictures contained in this section are intended to be used as a visual aid to assist in
explaining the operation of a Interstater flail mower and are not specific to any model. Some pictures may show
shields removed for picture clarity. NEVER operate implement without all shields in place and in good
operational condition. The operator must be familiar with the mower and tractor and all associated safety
practices before operating the mower and tractor. Proper operation of the mower, as detailed in this manual,
OPERATION
will help ensure years of safe and satisfactory use of the mower.
IMPORTANT: To avoid mower damage, retorque all bolts after the first 10 hours of operation. Refer to the
