operator who recognizes the potential hazards and follows reasonable safety practices. The manufacturer has
designed this implement to be used with all its safety equipment properly attached to minimize the chance of acci-
dents.
BEFORE YOU START!! Read the safety messages on the implement and shown in your manual. Observe the
rules of safety and common sense!

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 Agricul-
tural 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 oper-
ation of their mowing equipment and be able to recognize the potential hazards that can occur while oper-
ating 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 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 Group Ag.
If you would like a VHS video tape of the video, please email AEMV[email protected] or Fax
AEM VHS Video at [phone] 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
intended use, and the potential hazards before operating the equipment.

SAFETY
General Safety Instructions and Practices
A safe and 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 safely and 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.
The lowest level of Safety Message; warns of possible injury. Decals located on the Equipment
with this Signal Word are Black and Yellow
Serious injury or possible death! Decals are Black and Orange.
Imminent death/critical injury. Decals are Red and White. (SG-1)
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.
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
Operator Safety Instructions and Practices
Engine Exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the state of California to cause cancer and birth defects or other reproductive
harm. (SG-30)
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)
“Wait a minute...Save a life!”
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)

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 too 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, sa
f
ety shoes,
safety glasses, and proper hearing protection at all times for protection from
injury including injury from items 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)

handling oil, solvents, cleansers, and any other chemical agent. (SG-22)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and
possible serious injury or death. (SG-24)
Never allow children to play on or around Tractor or Implement. Children can slip or fall off the
Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing
themselves or others. (SG-25)
NEVER use drugs or alcohol immediately before or while operating the Tractor
and Implement. Drugs and alcohol will affect an operator’s alertness and
coordination and therefore affect the operator’s ability to operate the equipment
safely. Before operating the Tractor or Implement, an operator on prescription
or over-the-counter medication must consult a medical professional regarding
any side effects of the medication that would hinder their ability to operate the
Equipment safely. NEVER knowingly allow anyone to operate this equipment
when their alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of drugs or
alcohol. (SG-27)

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 gound 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)
