In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, 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 Ag 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 V ideo 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 Group Ag.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax
AEM VHS Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to
AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please
include your name, mailing address, mower model and serial number.
Every operator should be trained for each piece of equipment (Tractor and Mower), understand the

how to stop the tractor engine suddenly in an emergency. Never allow inexperienced or
untrained personnel to operate the Tractor and Implement without supervision. Make sure
the operator has fully read and understood the manuals prior to operation.
(SG-4)
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by the equipment.
(SG-16)
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an Implement
attached can often be noisy enough to cause perman ent hear ing lo ss. 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 pe riod of time will cause per manent or
total hearing loss. NOTE: Hearing loss from loud noise [f rom tractors, chain saws, radios ,
and other such sources close to the ear] is cu mulative over a lifetime withou t hope of natural
recovery.

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.

Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify
passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If
you are unable to clearly see these type of items discontinue mowing.
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if shields are not
properly installed and maintained. Serious injury or even death may occur unless care is
taken to insure the safety of the operator, bystanders, or passersby in the area. Do not
operate this machine with anyone in the immediate area. Stop mowing if anyone is within
100 yards of mower.

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
marked and carefully avoided by the operator. Stop mowing immediately if blades strike a
foreign object. Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing.
(SGM-5)
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 b lades. Such a s ituation is extre mely hazardous and could result in serious injur y
or even death. Inspect the cutting area for such objects before mowing. Remove any like obje ct from the site.
Never allow the cutting blades to contact such items.

Connecting or Disconnecting Implement Safety Instructions and Practices
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Mower resulting in
excessive vibration, thrown objects, and blade and mower failure. Adapter use will also change the working
length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can
result from using a PTO adapter. Consult an authorized dealer for assistance if the Implement driveline does
not match the Tractor PTO.

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.

the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious
damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or
downward onto the PTO shaft, breaking it off. A broken drive line can cause personal injury.

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 fron
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 prev ent loss of st eering co ntrol w hich
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 tracto
and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)

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. Co ntacting a
solid object while turning will cause equipment damage and possible injury.
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clea rly visible and legible. When transporti ng the
Equipment use the Tractor flashing warnin g light s and follow a ll 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.
(S3PT-20)
SAFETY
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 towing this equipment.
(SG-6)
• Test the equipment at a slow speed in turns. Increase the speed through the turn only
after you determine that it is safe to operate at a higher speed. Use extreme care and
reduce your speed when turning sharply to prevent the tractor and implement from
turning over. Determine the maximum safe turning speed for you and this equipment
before operating on roads or uneven ground.
• 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.
e particularly careful when transporting the Implement using the tractor. Turn curves or
go up or down hills only at a low speed and at a gradual steering angle. Make certain that
at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces.

Maintenance and Service Safety Instructions and Practices
(STI-6)
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 you
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)
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)
SAFETY
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the Remote
Cylinder lever in and out several times prior to starting any maintenance or
repair work.
(S3PT-9)
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Implement. Never work on the Implement with the tractor PT O d riveline connected a nd
