General Safety Instructions and Practices
SAFETY
A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to
the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and
observing certain precautions. The first section of this manual includes a list of Safety Messages that, if
followed, will help protect the operator and bystanders from injury or death. Read and understand these Safety
Messages before assembling, operating or servicing this Implement. This equipment should only be operated
by those persons who have read the manual, who are responsible and trained, and who know how to do so
responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment. The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word
are intended to warn the owner/operator of impending hazards and the degree of possible injury
faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU. Only YOU can prevent serious injury or death from unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or
repair.(SG-1)
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards. (SG-2)

SAFETY
Battery posts, terminals and related accessories contain lead and lead compounds,
chemicals known to the state of California to cause cancer, birth defects or other
reproductive harm. (SG-31)
Operator Safety Instructions and Practices
(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. (SG-I7)
Always read carefully and comply fully with the manufacturer’s
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)
EK-II 03/09

Safety Section 1-3
SAFETY
Never operate the Tractor or Implement until 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.
SAFETY
SAFETY
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)
Prolonged 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. (SG-32)
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
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. (SG-33)
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. (SG-34)
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)
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. (S3PT-10)

Safety Section 1-4
SAFETY
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. (S3PT-19)
The rotating parts of this machine continue to rotate even after the Tractor 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. (SBM-5)
“Wait a minute...Save a life!”
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)
Do not put hands or feet near the cutter bar. Blade contact can result
in serious injury. Stay away until all motion has stopped and the
mower is securely blocked up. (SSM-1)
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-03)
Connecting & Disconnecting Implement Safety Instructions & 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. (S3PT-15)
EK-II 03/09

Safety Section 1-5
SAFETY
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. (SFL-2)
SAFETY
SAFETY
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. 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. (S3PT-17)
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. (S3PT-18)
Each Rear Wheel must have a minimum of 1500 pound contact with the
surface to prevent lateral instability and possible tip-over which could
result in serious bodily injury or even death. Widen the wheel tread and
add weights if needed. Refer to the mounting instructions or call Customer Service if you
need assistance with Couterweight Procedure. (SBM-11)
Do Not attempt to raise or lower the boom or mower head unless the Implement is securely
attached to the Tractor. The Implement could tip over and cause equipment damage and
possible serious injury or death. Do Not use the boom controls to assist in installing the
implement on the tractor. Raise or Lower the boom and mower head only while seated in the Tractor
operator’s seat with the seat belt securely fastened. Inadvertent contact with the boom controls could allow a
component to fall. A sudden or inadvertent fall by any of these components could cause serious injury or even
death. (SBM-23)
EK-II 03/09

Safety Section 1-6
SAFETY
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)
Use extreme caution when raising the Mower head. Stop the Blades from turning when the
Mower Head is raised and passersby are within 100 yards. Raising the Mower head
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. (SBM-2)
Never Leave the mower unattended while the head is in the raised
position. The mower could fall causing serious injury to anyone who
might inadvertently be under the mower. (SBM-4)
Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead
power lines consult your electric company for a safe code of operation.
(SBM-7)
The center of Gravity of Tractors equipped with a Rear-Mounted Boom
Mower is shifted to the rear and removes weight from the front wheels.
Add front ballast until at least 20% of the tractors weight is on the front
wheels to prevent rearing up, loss of steering control, and possibly
injury. (SBM-10)
The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.
(SBM-15)
Use extreme care and Safety Awareness when using the boom mower head to mulch loose
brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this
debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This cut debris can be
thrown at great velocities and could result in serious injury or even death. (SBM-17)
EK-II 03/09

Safety Section 1-7
SAFETY
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)
SAFETY
Do not back up this implement when the boom or mower head is extended. Backing could
damage the machine or its components. (SBM-19)
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.
SAFETY
-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.
-Do Not attempt to mow or place the mower head close to
burning debris.
-Never allow clippings or debris to collect near drivelines,
gearboxes or hydrualic componts such as valves, tanks,
pumps and motors. Periodically shut down the Tractor and
Mower and clean clippings and collected debris from the
mower deck. (SBM-20)
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)

Safety Section 1-8
SAFETY
Flail Mowers are capable under adverse conditions of throwingobjects
for great distances (100 yards or more) and causing seriousinjury 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,
workablecondition;
-Mower sections
or Wings are running close to and parallel to the ground
withoutexposed Blades;
NOTE: Where there are grass and weeds high enough to hide debris that could
bestruck by the blades, the area should be: inspected and large debris removed, mowed
atan intermediate height, inspected, closely with any remaining debris being removed,
andmowed 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,
eliminatestreaking, and make the final cut more uniform.) (SFL-6)
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. (SG-10)
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. (SG-11)

Safety Section 1-9
SAFETY
-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.
SAFETY
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. (SG-12)
SAFETY
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. (SG-13)
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-15)
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. (SG-29)
In case of mechanical difficulty during operation, place the transmission in the park
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. (SG-39)
EK-II 03/09

Safety Section 1-10
SAFETY
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. (SG-40)
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. (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. (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-05)
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-06)

Safety Section 1-11
SAFETY
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. (SGM-1)
SAFETY
Mow 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. (SGM-07)
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.
SAFETY
(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:
-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)
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 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)
Never leave the Implement and Power Unit unattended while the Implement is in the raised
position. Accidental operation of a lifting lever or a hydraulic failure may cause the
implement to suddenly fall causing serious injury or possible death to anyone who might
inadvertently be under the Implement. Lower the implement carefully to the ground. Do not
put hands or feet under lifted components. (SPU-3)

SAFETY
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-04)
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-07)
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)
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)
Never interfere with factory-set hydraulic calibrations. Any change in calibration could
cause a failure of the equipment and may result in injury. (SBH-13)
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 disconnect the wire leads from the mower valve solenoid
before performing service on the Tractor or Mower. Use caution when
working on the Tractor or Mower. Tractor engine must be stopped
before working on Mower or Tractor. The Mower Blades could
inadvertently be turned on without warning and cause immediate
dismemberment, injury or death. (SBM-12)
All Safety Shields, Guards and Safety devices including (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

Safety Section 1-15
SAFETY
Use caution and wear protective gloves when handling sharp objects such as blades,
knives, and other cutting edges. Be alert to worn component surfaces which have sharp
edges. Sharp surfaces can inflict severe laceration injuries if proper hand protection is not
worn. (SG-37)
SAFETY
Transporting Safety Instructions and Practices
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 or
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.
SAFETY
(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
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
Be particularly careful in transport. The Mower has raised the center of
gravity for the tractor and has increased the possibility of overturn.
Turn curves or go up slopes only at low speed and using a gradual
turning angle. Slow down on rough or uneven surfaces. (SBM-3)
When transporting Boom Mower on a truck or trailer, the height or width
may exceed legal limits when the boom is in the transport position.
Contact with side or overhead structures or power lines can cause
property damage or serious injury or death. If necessary lower boom to
reduce height and/or remove mowing head to reduce width to the legal
limits. (SBM-8)
Never operate the Tractor and Mower Unit without an OPS (Operators
Protective Structure) or Cab to prevent injury from objects thrown from
ground or from overhead trimming.
Stop mowing if workers or
passersby are with in 100 yards. (SBM-9)
The Joystick Master Control Switch must be OFF to prevent accidental movement of the
boom and cutting head whenever the mower is not being operated. (SBM-16)
Secure the boom and mower head in the transport position before traveling on public roads.
Never transport on public roads with the boom and mower head extended. Always
disengage and lock out the hydraulic controls for the boom mower before transporting.
Inadvertent boom movement on public roads may contact with other vehicles resulting in
serious bodily injuries or even death. (SBM-21)

Safety Section 1-16
SAFETY
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)
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.
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. (SG-19)
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before
driving on public roadways identify any limited vision areas, and make adjustments to your
operating position, mirrors, and the implement transport position so that you can clearly
see the area where you will be traveling, and any traffic that may approach you. Failure to
maintain adequate vision of the public roadway and traffic can result in serious injury or
even death. (STI-10)
Storage and Parking Safety Instructions and Practices
A rear Implement can fall if not properly supported. Always use the stand on the front hitch
(if equipped) or block up securely to prevent falling and possible crushing injury and/or
other injury from holding or lifting heavy components. Use the stand to stabilize the
implement during storage. (S3PT-3)
EK-II 03/09

INTRODUCTION
Your Exten-A-Kut mower is designed for mowing pond embankments, weeds, and grass or other agricultural applications that may apply. With a reasonable amount of preventive maintenance, your Mower will
provide years of dependable service.
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 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% or the tractor’s 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.
Front and rear and left and right are determined by the normal direction of travel, the same as driving an
automobile.

NOTE: This mower unit's hydraulic components have been carefully cleaned and packaged at the factory
to prevent contamination from entering the system. However, dust and dirt particles may enter into the
sealed components through transportation, handling, rain or just sitting in a dirty or harsh environment.
Therefore to assure that the hydraulic system is properly clean please adhere to the following procedure.
Prepare the area where the unit is to be assembled. The area should be on a hard concrete floor that has
been swept clean of all dust and contaminants. Un-package the mower unit carefully so that the seals on
the hydraulic components are not broken or pulled off. Lay out parts to make location easy.
Inspect and clean all hydraulic hoses and fittings prior to installing them onto the tractor or mower. If dirt or
material is seen in any of the parts, they should be washed and cleaned thoroughly with an oil-compatible
solution. Do not blow the material further into a hose since this sometimes does not remove the foreign
material and can cause damage to hydraulic components down stream.

ATTACHMENT OF HYDRAULIC HOSES
Once pumps are installed, DO NOT start the tractor (which will turn the pumps) unless
the hydraulic circuits are completed and filled with the specified universal tractor
hydraulic oil. Running pumps without oil will cause non-warrantable damage.
It is important that pipe thread sealant be used only on pipe threads; never on
connections or on straight thread "O" ring fittings. Use the pipe thread sealant supplied. Do not substitute
with some other type of sealant, such as, teflon tape, paint, shellac, etc.
Hoses supplied have two types of fittings; solid or swivel. Some hoses have solid fittings on both ends;
others have solid fitting and a swivel fitting. Hoses with two solid fittings will fit into either a internal solid
thread or a swivel adapter union. When installing either type hose, solid fittings must be installed first, then
install the swivel end of the hose or fitting.
a. Standard pipe (NPT or NPTF) thread fittings. This type requires a small amount of evenly-applied
sealant.
b. Swivel fittings. This type does not require any sealant on the swivel end because it seals against an
internal flare.
c.
"O" Ring fittings. This type does not require any sealant on the "O" Ring end of the fitting.
It is extremely important to avoid getting pipe thread sealant inside the fittings or hoses. KEEP THE
INTERIOR OF ALL HYDRAULIC COMPONENTS CLEAN. Inspect the inside diameter of each hose
before assembly. Make certain that no obstruction is present. Dirt, sand, dust, etc., are abrasive and once
it the system can cause immediate or early failure.
When assembling the fittings and hoses, be careful not to introduce any dust or contaminants into the
system. Keep all fittings, hoses, and hydraulic components sealed until installed. Do not allow any
components to lie open and exposed to dust or contamination. Do not lay parts down on the dirt or sand
and then assemble them as this will introduce contaminants into the system.

Oil Reservoir is shipped filled with oil to the minimum level. When adding hydraulic oil proceed.
ASSEMBLY
1. Remove the Filler Cap Weldment. FIGURE Asm-B-0007.
2. Avoid hydraulic contamination by filtering the hydraulic oil while filling the hydraulic tank. Filter buggies
or carts are commercially available for hydraulic system clean-up. These consist of a high-efficiency, highcapacity filter, a circulating pump, a drive motor, and hoses for connecting to the overhauled machine's
hydraulic system. FIGURE Asm-B-0008 & Asm-B-0009
.
3. When adding hydraulic oil, use only new oil from a sealed barrel. Used oil or oil from an open barrel
may contain high levels of contamination. Transfer the oil into the hydraulic tank by using a hydraulic filter
pump unit equipped with a properly operating 10 micron filter. This will insure that the oil being added is
clean. Do not just pour the oil directly into the hydraulic tank since most oils (even from a sealed barrel)
have contaminants that should be removed, before operating the hydraulic system.

6. When the hydraulic tank has been filled and the mower unit properly assembled, the unit should be
started up. NOTE: Make sure that no materials, tools, or jacks have been left under the mower head.
Make sure the front and rear of the mower are properly guarded to prevent any foreign objects from being
thrown by the mower. All other workers should keep a safe distance from the unit before the mower is
started.
7. Run the mower at 1000 RPM tractor engine speed for at least two hours.
IMPORTANT: Change the return filter in tank and suction filters after the first 200 hours of operation.
Change the filters again at 800 hours; then, change the oil and filters at 1600 hours. After that, continue to
change the filter every 800 hours and the oil every 1600 hours. Hydraulic oil to be used is, Universal

3-Point Hitch-Lifting Capacity ........... 2140 lbs.
-Category................................... CATI- II Quick Hitch
Front End Weight ............................ As needed to maintain 20% weight on front axle
Power Take Off ................................ 540 rpm-6 spline or 1000 rpm-21 spline shaft
3.1 ROPS and Seat Belt
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.
Tractor model not equipped with a ROPS and seat belt should have these life saving features installed by an
authorized dealer. OPS-U- 0003
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)
3.2 Tractor Safety Devices
If transporting or operating the tractor and implement 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.
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 implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
3.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the DB150 Boom Mower requires a tractor with at least 60 HP. Operating the mower with a tractor
that does not have adequate power may damage the tractor engine. Exceeding 60 HP may cause mower
damage by overpowering the unit in heavy cutting conditions.

3.4 3-Point Hitch
OPERATION
The tractor 3-point hitch must be rated to lift at
least 2140 lbs.
The EK II boom mower is designed to be
mounted on a tractor with a CAT I or II 3-point
hitch. Refer to the tractor operator’s manual for
the category of the tractor being used. If the
hitch does not conform to ASAE CAT I or II
dimensions, the mower may not fit or raise
properly. Consult an authorized dealer for
possible modification procedures to mount
nonconforming hitches.
Depending on the hitch category, certain size
pins are used to attach the mower to the
tractor. CAT II hitches require 7/8” lower and 3/4” upper diameter hitch pins. CAT III hitches require 1-7/16”
lower and 1-1/4” upper diameter size pins.

Lynch pin diameter.................................. 15/32”
Lynch pin diameter ..................................15/32”
3.5 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. OPS-U- 0005
3.6 Power Take Off (PTO)
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 6-spline shaft and those operating at 1000 RPM will have a 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
over-running 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. OPS-U- 0006
EK II 03/09
©2009 Alamo Group Inc.
Operation Section 3-6
OPERATION
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)
4.GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007
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. (SG-12)
4.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt
around you.
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be
seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra
riders at all times. OPS-U- 0008
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. (SG-11)
EK II 03/09
©2009 Alamo Group Inc.
Operation Section 3-7
OPERATION
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-16)
OPERATION
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
OPERATION
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. (SG-12)
4.2 Dismounting the Tractor
Before dismounting the tractor, idle the tractor engine down, disengage the head and retract the boom arm to
the transport position. Park the tractor on a level surface, set the transmission in park or neutral and apply
the parking brake. Shut down the tractor engine, remove the key, and wait for all motion to come to a
complete stop before exiting the operator’s seat. NEVER leave the seat until the tractor, its engine, and
mower head movement have come to a complete stop.
Use hand rails and extra steps when exiting the tractor. Be careful of your step and use extra caution when
mud, ice, snow, and other matter has accumulated on the steps and handrails. Never rush or jump off the
tractor. OPS-B- 0002
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)

OPERATION
5.STARTING THE TRACTOR
The operator must have a complete understanding of the placement, function, and operational use of all
tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
Essential Tractor Controls:
Locate the ignition key/switch
Locate the engine shut off control
Locate the hydraulic control levers
Locate the light control lever
Locate the brake pedals and clutch
Locate the PTO control
Locate the 3 point hitch control lever
Locate the boom operating controls (joystick or valve bank)
Before starting the tractor ensure the following:
•
•
•
•
•
•
•
Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
Make sure all guards, shields, and other safety devices are securely in place.
The parking brake is on.
The tractor transmission levers are in park or neutral.
The boom operating controls are in the neutral and off position.
The PTO control lever is disengaged.
The hydraulic remote control levers are in the neutral position.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-B- 0003
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 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. (SG-13)
6.CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at
ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points
between the tractor hitch arms and mower pins. OPS-R-0001

OPERATION
Never stand or allow another person to stand between a running Tractor and the Mower
when attaching the Implement to the Tractor. Always shut the Tractor completely off before
attempting to connect the Mower pins to the Tractor hitch.
OPERATION
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)
6.1 Connecting the Boom Mower
1. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid
interference when raising and lowering the
boom mower.
3. Board the tractor and start the engine. Position
the tractor to the boom mower with the 3-point
lift arms positioned between the respective set
of A-frame lift lugs. NOTE: Set the 3-point lift
control to “Position Control” so that the lift arms
maintain a constant height when attaching the
boom mower. See the tractor Operator’s Manual for correct settings when attaching 3-point
equipment.
4. Turn off the tractor engine and dismount.
5. One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert hitch
pin through the lug and arm holes and insert
retaining pin into hitch pin.
6. Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.
7. Extend or retract 3-point top link to align its end
hole with the holes of the mower’s top link.
Insert the top link hitch pin and insert retaining
pin into hitch pin.
8. Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact
with tractor rear tires.
7.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: Avoid 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. OPS-U- 0010
EK II 03/09

Operation Section 3-10
OPERATION
7.1 Setting Boom Mower Height
1. Park the tractor and boom mower on level
ground.
2. Shut down the tractor and remove the key.
3. Level the boom mower from front to rear by
extending or retracting the 3-point top link.
NOTE: Install optional check chains when there is
a problem with the hydraulic 3-Point lift maintaining
a set height or when a constant pre-adjusted cut
height is required.
8.DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor PTO
output shaft, pull the driveline yoke collar back 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. OPS-R-0003_A
EK II 03/09

Operation Section 3-11
OPERATION
4. Level the mower side to side by manipulating
one lower lift arm length. On most tractors, at
least one of the lift arms is designed to allow for
manipulation of its length.
Shortening or
extending will allow for deck leveling from side
to side.
5. Securely block up the mower at this height.
OPERATION
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. 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. (S3PT-17)
OPERATION
8.1 Driveline Length Check
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. (S3PT-18)
Raise mower and watch the Driveline as it
approaches the colored tape. If the distance
between colored tape and the end of the outer
shield tube is 2" or less, Drive Tubes should be
shortened per figure Op-10.
Always maintain 2" clearance when operated in
shortest working position. Shorten inner and outer
guard tubes equally. Shorten inner and outer
sliding profiles by the same amount that the shield
tubes were shortened. Round off all sharp edges
and remove burrs. Grease sliding profiles. Figure
Op-11_A.
Lower mower to lowest position possible. Turn off
the Tractor and apply Parking Brake. Apply a
second piece of colored tape to the Inner Shield 1/
8" from the end of the Outer Shield. Disconnect
Driveline from Tractor and then separate the two
Driveline halves. Check the distance from the new
piece of colored tape to the end of the inner profile.
If distance is less than 8" consult dealer to obtain a
longer Driveline. Driveline Tube engagement must
always exceed 8".

9.PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the implement 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 unit 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. OPS-U-0029
All Safety Shields, Guards and Safety devices including (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)

10.DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator to 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 boom and the tractor operating controls are set for safe transport. To ensure safety
while driving the tractor with a boom, review the following.
Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for
engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating 540
PTO speed. Always engage the PTO at low engine RPM and run the mower for a short period until all air is
removed from the hoses. Keep all person's well clear of mower since blades can throw objects with great
velocity for a considerable distance! KEEP CLEAR! OPS-B- 0005
Never operate the Tractor or Implement until 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)
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. (SG-5)
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)

Operation Section 3-23
OPERATION
Read all safety instructions. Decals on the Boom warn you of particular and multiple hazards. Some decals
are attached close to part of the Boom where there is a possible hazard. Read and make sure you
understand the safety messages before you operate the implement. Keep all decals clean and readable.
Replace lost or damaged decals, refer to safety section for more information.
OPERATION
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.
OPERATION
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.
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. (SG-19)
10.1 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. OPS-U-0033

10.2 Brake and Differential Lock Setting
Always disengage the tractor differential lock
when turning. When engaged the differential lock
will prevent or limit the tractor from turning. During
normal cutting conditions, locking the differential
provides no benefit and should not be used.
OPS-U- 0013
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.
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)
10.3 Driveline Angle Problems
Due to the shape or contour of the area being mowed, it may be necessary to raise tractor 3 pt. causing severe

10.4 Driving the Tractor and Boom
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor. Never operate the tractor 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.
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. Use extreme caution when
operating on steep slopes. Keep the tractor in a low
gear when going downhill. DO NOT coast or freewheel downhill.
OPS-B- 0006_C
Never Leave the mower unattended while the head is in the raised
position. The mower could fall causing serious injury to anyone who
might inadvertently be under the mower. (SBM-4)
Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead
power lines consult your electric company for a safe code of operation.
(SBM-7)
EK II 03/09

Operation Section 3-27
OPERATION
Perform turns with the tractor and mower at slow
speeds to determine how the tractor with and
attached implement handles a turn. Determine the
safe speed to maintain proper control of the tractor
when making turns. When turning with the
implement the overall working length and width of
the unit is increased. Allow additional clearance for
the unit when turning or when passing large
obstructions.
OPERATION
11.OPERATING THE BOOM UNIT AND ATTACHED HEAD
OPERATION
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand
the Safety and Operation Sections of this manual and the tractor operator’s manuals. These manuals must
be read and explained to any operator who cannot read. Never allow someone to operate the unit without
complete operating instructions.
To ensure safety to the operator, bystanders, and equipment and before starting any mowing operation. The
operator must become familiar with the area to be mowed, and any obstacles and hazards contained within.
Special attention should be paid to foreign debris, overhead obstrucions, rough terrain, steep
slopes,passersby and animals in the area.
Only operate the mower head from the tractor operator’s seat with the seatbelt securely fastened. Only
operate a boom and equipped head on cabbed tractor that is equipped with a Lexan protected right side
window or a non cabbed tractor equipped with a ROPS and operator safety screen.
®
Avoid operating in the reverse direction when possible. In situations where the boom and mower must be
backed to access areas to be cut, make sure there are no persons or other foreign debris behind the tractor.
When backing, operate the tractor at a much reduced ground speed to ensure complete control of the unit is
maintained. OPS-B- 0007
OPERATING INSTRUCTIONS
Engage the PTO shaft at low engine RPM and speed the engine up after blades are fully engaged. Never
engage the PTO shaft at a high engine RPM. This could cause damage to the PTO shaft as well as the Speed
Increaser and Pump. Always operate PTO at the recommended RPM when mowing. This is necessary to
maintain proper blade speed and to produce a clean cut.
Proper ground speed for cutting will depend upon the height, type, and density of material to be cut. Normally,
ground speed will range from 2 to 5 mph. Tall dense material should be cut at low speed while thin medium
height material can be cut at a faster ground speed.
Always run the Mower at the highest position which will enable you to obtain the desired cutting results.
Allowing the blades to cut into the ground will cause wear and undue strain on the mower frame and mower
components.
If you are mowing in conditions of heavy growth or rough ground where the blades cut into the ground and the
tractor engine slows down, do not slip the clutch to allow the engine to speed up and engage the clutch again.
This procedure exerts tremendous strain on Mower components. Always disengage the PTO and move
forward or backwards until the machine is clear.
This mower is designed with free swinging blades. This feature reduces the amount of shock transmitted to
other components. Always make sure the blades can swing freely on the blade bar.
When cutting foliage and fine shredding is desired, run the mower level or slightly lower in the rear so as to
keep the material in the mower until it is shredded. This will require more power but will shred better. When
cutting heavy foliage and fine shredding is not desired, raise the rear of the mower. This will allow the high
volume of material to be discharged and requires much less power.
Do not ride the clutch on the tractor. Mow in the appropriate gears to give the correct ground speed.
EK II 03/09
©2009 Alamo Group Inc.
Operation Section 3-28
OPERATION
Extremely tall grass should be cut twice. Raise mower and cut twice the desired height. Cut the second time
at desired height at 90 degrees to first pass.
Remember, sharp blades produce cleaner cuts and use less power.
Before cutting, analyze the area to determine the best cutting procedure. Consider the height and type of
material and the terrain type: hilly, level or rough.
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
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)
Never operate the mower head tilted down where the operator can see the blades of the
mower. The blade could throw an object toward the operator causing serious injury or
death. Never operate the mower without an Operator Protective Structure. Always were
safety glasses and a hard hat. (Ops-0005-MISC)
Operating the Control Valve
The optional 2-spool Control Valve should be located to the right of the operator at a convenient height.
EXTEND CYLINDER
The first handle on the control valve actuates the Extend Cylinder. This valve has three positions and operates
in three ways.
Push the valve handle forward and you admit hydraulic fluid to the Dead End of the Extend Cylinder, causing
the Mainframe Boom to extend outward.
If the handle is released, the valve will automatically return to center, and the Boom will be Locked in place.
Pull the valve handle back towards you and admit hydraulic fluid to the Rod end of the cylinder causing the
boom to return toward the tractor.
Again, if the valve handle is released, the valve will automatically return to center and the boom will be Locked
in place.
TILT CYLINDER
EK II 03/09
©2009 Alamo Group Inc.
Operation Section 3-29
OPERATION
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. (SGM-1)
OPERATION
The second handle on the control valve actuates the Tilt Cylinder. This valve has three positions and operates
in three ways.
Push the valve handle forward and you relieve pressure on the Rod End of the Tilt Cylinder, causing the Mower
Head to tilt downward.
If the handle is released, the valve will automatically return to center, and the Mower Head will be Locked in
place.
OPERATION
Pull the valve handle back towards you and admit hydraulic fluid to the Rod end of the cylinder causing the
Mower Head to tilt upward.
Again, if the valve handle is released, the valve will automatically return to center and the Mower Head will be
Locked in place.
11.1 Foreign Debris Hazards/Overhead Obstructions
An area to be cut must first be inspected for objects that could be thrown or that could damage the machine.
Walk through the area looking for fences, boulder, rocks, culverts, stumps or metal objects. Mark the inspected
area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect a smaller
area as well as possible, then trim away the part that has been inspected and can safely be removed. Walk
each new area again and repeat the inspection before cutting more away. Repeat as often as necessary until
the area is cleared. It can be damaging and/or dangerous to work the cutter in an area that had not been
visually inspected.
Place DANGER signs at least 300 feet beyond the perimeter of the area to be worked, not just 300 feet from
where the machine started operating! It is convenient in many cases to work in 300 foot sections. Move the
first Danger sign to the beginning of the freshly cleared area, place it, then take the first cutting area flag up to
the end of the freshly cleared area 300 feet away. Walk and inspect the next 300 feet and place the second
cutting area flag. Pick up the second DANGER sign, and take it a further 300 feet along the road or trail. Note
that in many cases the DANGER area will extend in front of and behind the machine as well as along each
side. Post signs accordingly. OPS-B- 0008
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-05)
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-06)
EK II 03/09
©2009 Alamo Group Inc.
Operation Section 3-30
OPERATION
Mow 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. (SGM-07)
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
Front and Rear Deflectors are installed and in good, working condition;
Mower Head is 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 dsebris being removed, and
mowed again at desired final height. (SBM-1)
11.2 Operating Speed and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not
exceed 2 MPH while operating. 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 operating and desired ground speed. Make sure that the mower is operating at its full
rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near
idle.
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 implement 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. OPS-B- 0009

lines, or when debris and foreign objects are to be avoided. (SGM-07)
OPERATION
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. (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. (SGM-4)
All Safety Shields, Guards and Safety devices including (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)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the

OPERATION
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.
12.1 Transporting on Public Roadways
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. OPS-B- 0014
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 and implement on a public roadway.
Replace the SMV emblem if faded, damaged, or no
longer reflective. OPS-U- 0020
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the implement at speeds
greater than 20 MPH (25 kph). OPS-U- 0018
OPERATION
OPERATION
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 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 where only equipped with
operating lights. Consult an authorized tractor
dealer for lighting kits and modifications available
to upgrade the lighting on older tractor models.
OPS-B- 0015_A
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. Do not exceed the legal speed limit set in
your country for agricultural tractors. Always stay
alert when transporting the tractor and mower on
public roads. Especially in busy cities, the boom
extends to right farther then the tractors width, so
be careful there are no bystanders, poles,large
obstructions or any vehicles that may be in path of
the mower head on boom. Use caution and reduce
speed if other vehicles or pedestrians are in the
area. OPS-B- 0016_A
When transporting Boom Mower on a truck or trailer, the height or width
may exceed legal limits when the boom is in the transport position.
Contact with side or overhead structures or power lines can cause
property damage or serious injury or death. If necessary lower boom to
reduce height and/or remove mowing head to reduce width to the legal
limits. (SBM-8)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

OPERATION
Use adequately sized and rated trailers and
equipment to transport the tractor and implement.
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. OPS-U- 0025
Arrange the chains so that when tightened, the
chains are pulling downward and against
themselves. Carefully tighten the securing chains or
other fasteners 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 and implement, make
occasional stops to check that the tractor and
implement 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. OPS-U- 0026

BLADE SERVICING
MAINTENANCE
Inspect blades before each use to determine that they are properly installed and in good condition.
Replace any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be
ground out when sharpening.
When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause
excessive vibration which can damage gear box bearings. Vibration may also cause
structural cracks in the mower.
Use only original equipment blades on this mower. They are made of special heattreated alloy steel. Substitute blades may not meet specifications and may fail in a
hazardous manner that could cause injury.
When changing Blades always replace the Blade Bolt & Blade Nut at the same time.
Reuse of Blade Bolts or Nuts could fail in a hazardous manner that could cause injury.
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as
shown in Figure 4. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not
sharpen blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade.
Avoid personal injury. Always block the mower up to prevent if from falling when the
blades and/ or carrier are being serviced.
Avoid Personal injury. Always wear safety glasses and face protection when grinding
blades.
Do Not heat, weld, or hard surface blades as this can alter material strength causing
blades to fail in a hazardous manner that could cause injury.

BLADE REMOVAL
To remove blades for sharpening or replacement, remove the cover plate on deck of mower near Hyd
Motor. Remove lock nut from blade bolt. NOTE: Inspect lock nut after removal and replace if threads are
damaged. Always replace nut when replacing blade bolt. When installing blades be sure and check blade
bolt pivot diameter for wear. Replace bolt if worn more than 1/4 inch at any point. Tighten lock nut to 350
ft. lbs.
BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on spindle shaft. Loosen but do not remove the nut until the
blade carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered spindle shaft. If gear
puller is not available use long bar inserted through blade bolt access hole with end against rotor bar.
Strike opposite end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.
BLADE CARRIER INSTALLATION
Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft
and install special washer nut.
Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the carrier near the hub several times
with a heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and
threads. Retighten the nut to 450 ft. pounds. Install cotter pin and spread.
IMPORTANT! Always recheck spindle output shaft slotted blade carrier retaining nut torque after a few
hours operation.
Avoid personal injury. Do not work under mower without support blocks to keep frame
from falling.

STORAGE
Your mower represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the mower should be thoroughly checked and prepared for storage so that a
minimum amount of work will be required to put it back into operation for the next season. The following
are suggested storage procedures:
1. Thoroughly clean the mower.
2. Lubricate the cutter as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the mower for worn or damaged parts. Make replacements immediately.
5. Store the mower in a clean, dry place with the mower head resting on blocks.
6. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the
mower.
PROPER TORQUE FOR FASTENERS
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer
to this chart to determine the grade of bolts and the proper torque except when specific torque values are
assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL*
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal

Maintenance Section 4-7
MAINTENANCE
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder
rods to prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder
function so that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating
environment it may be necessary, under normal operating conditions, to apply a protective lubricant to the
cylinder rods for protection against rust and pitting. Hydraulic fluid may provide a suitable amount of
protection, but remember any protectant can attract dust and debris so attention must be given to the
cylinder rods daily. Also remember that any other protectant must be compatible with hydraulic fluid. Alamo
Industrial is not responsible for rust or pitting of the cylinder rod due to weather exposure or impacts from
normal operation or mounting. If hydraulic cylinders and or the cylinder rods are damaged as a result of the
rods rusting or pitting, the hydraulic cylinders and rods will not be covered under warranty by Alamo
