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 mail 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.

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 stan d and put the retaining pin securely in place, or pu t a secure
support under the A-Frame. Lower the implement carefully to th e ground. Do no t put hands
or feet under lifted components.
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.
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 serio us hazard and can cause serio us injury by object s
thrown from the Blades or by contact with the Blades.

(SBM-2)
SAFETY
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 Aw areness when using the boom mower h ead 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.
Do not back up this implement when the boom or mower head is extended. Backing could
damage the machine or its components.
Follow these guidelines to reduce the risk of equipment and
grass fires while operating, servicing, and repairing the Mower
and Tractor:
-Equip the Tractor with a fire extinguisher in an accessible
location.
-Do Not operate the Mower on a Tractor with an underframe
exhaust.
-Do Not smoke or have an open flame near the Mower and
Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-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)
(SBM-19)
Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor
engine. Inspect the Mower to determ ine 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.

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
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 of f the tractor --particularly during a turnover
when the operator could be pinned under the ROPS.

SAFETY
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 contr ols 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.
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 imp ene trab le glo ves ,
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.

Do Not operate this equipment in areas where insects such as bees may attack you and/or
cause you to lose control of th e 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 yo u o r 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 objec ts. If you are unab le to clear ly see thes e type of ite ms
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.

(SGM-1)
(SGM-02)
SAFETY
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)
xtreme 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 mark ed and carefully a vo ide d b y th e
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.
(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.
(SGM-08)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed.

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.
Never leave the Implement and Power Unit unattended while the Imple ment is in the ra ised
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 gr ound. Do not
put hands or feet under lifted components.
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.

PARTS INFORMATION
Alamo Industrial mowers use balanced and matched system components for blade carriers, blades,
cuttershafts, knives, knife hangers, rollers, drivetrain components, and bearings. These parts are made and
tested to Alamo Industrial specifications. Non-genuine "will fit" parts do not consistently meet these
specifications. The use of “will fit” parts may reduce mower performance, void mower warranties, and present
a safety hazard. Use genuine Alamo Industrial mower parts for economy and safety.
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 lo ss 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
solid object while turning will cause equipment damage and possible injury.
SAFETY
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)
(S3PT-20)
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.
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clea rly visible and legible. When transporti ng 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.
(SG-6)
SAFETY
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 r educe your speed. Be aware of traf fic around you
and watch out for the other guy.
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.

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.
The tools you will need at the assembly site are as follows:
1. Impact wrench or socket and ratchet set.
2. Rubber mallet.
3. Box-end, Allen, and adjustable wrenches.
4. Alignment pins.
5. Forklift or hydraulic floor jacks with rolling back boards.
6. Small chain hoist or block-and-tackle.
7. Multidirectional Levels.
8. Hydraulic Filter Buggy or Cart.
9. Safety shoes, safety glasses, and gloves. A hard hat should be worn by anyone working under any
raised component.
Remember to follow each step closely and cautiously. Be aware of all support personnel at all times.
Keep the assembly area as clean as possible; clean up all spills when they occur. An uncluttered
assembly area and a crew that is sensitive to the hazards involved in putting this implement together will
help prevent accidents. Keep all unauthorized personnel from the area. Do not allow children near the
assembly site nor allow them on or near the tractor after assembly. There is no safe place for anyone
except the operator on the tractor and those assisting with the assembly.
1. Add front end weights as required to maintain enough weight on front wheels for safe steering.
Failure to add the required front end weight can cause tractor to rear up which can
cause equipment damage and bodily injury.
To prevent damage to the Hydraulic Pump, do not attempt to start tractor before
installing the hy draulic systems and filling the system with Universal Tractor Hydraulic
oil as specified.
MAINFRAME ATTACHMENT
With a forklift or hoist raise the Mainframe until it lines-up with the 3-point hit ch. Figure Asm-B-0001.

ASSEMBLY
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 no t 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.
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-e fficien cy, 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
.
ASSEMBLY
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.
4. Fill the Hydraulic Reservoir until the fluid is visible through the sight gauge. FIGURE Asm-B-0010 &
Asm-B-0011.
ASSEMBLY
5. Fill the Suction Hose with hydraulic fluid and re-install on Hydraulic Tank. Tigh te n ho se cla mp secur ely.
FIGURE Asm-B-0012 & Asm-B-0013
.
6. When the hydraulic tank has been filled and the mower unit properly as sembled, 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, chan ge th e 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
Tractor Hydraulic Oil. Use the above procedures as part of a good filter maintenance program.
ALAMO INDUSTRIAL DITCH AND BANK MOWER OPERATING INSTRUCTIONS
The Alamo Industrial Ditch and Bank Mowers are manufactured with quality material by skilled workers. The
EK II is designed to attach to a tractor and mow in pond embankments, weeds, and grass or other agricultural
applications that may apply. The boom and mower head is equipped with safety warning decals, protective
deflectors, shields, and other safety features to provide operator and passerby protection, however, no
shielding is 100% accurate. ALL safety equipment and safety warning decals must be maintained on the unit
in good operational condition at all times.
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
boom unit, tractor or a thrown object. Do not operate the boom and attached head if bystanders, passersby,
pets or livestock are within 300 feet of the unit.
This section of the Operator’s Manual is designed to familiarize, instruct, and educate operators to the safe and
proper use of the boom and attached head. Pictures contained in this section are intended to be used as a
visual aid to assist in explaining the operation of a EK II Mower and are not specific to a EKII Mower. Some
pictures may show shields removed to enhance visual clarity. NEVER operate the unit without all safety
equipment in place and in good operational condition. The operator must be familiar with the unit and tractor
operation and all safety practices before beginning operation. Proper operation, as detailed in this manual, will

•Gloves
•Hearing Protection
•Close Fitting Clothing
•Respirator or Filter Mask (depends on
operating conditions) OPS-U- 0002
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.
In addition to tractor horsepower and size required to operate the boom unit, the tractor must also be properly
equipped to provide operator protection, to alert approaching vehicle drivers of the tractor’s presence, and to
ensure tractor stability when mowing with the boom fully extended.

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
OPERATION
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 of f 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 nea r 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 r equ ires a t racto r with a t leas t 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.
The tractor 3-point hitch must be rat ed 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.
CAT I Implement / Hitch Specification CAT II Implement / Hitch Specification
OPERATION
Width from outside to outside A-frame.... 26-7/8”Width from outside to outside A-frame....32-3/8”
Quick Hitch width inside lug to lug ......... 27-1/8”Quick Hitch width inside lug to lug .........33-5/8”
Height from bottom hitch pin to top pin... 18”Height from bottom hitch pin to top pin ...19”
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 shaf t. Refer to the tr actor owner’s manual for in structions to chan ge PT O spee ds 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
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)
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 dise nga ge d. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation.
(S3PT-16)
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.
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.
(SG-12)
OPERATION
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.
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
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)
smounting 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.
OPERATION
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
(SG-10)
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 contr ols from the tractor seat only.
