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 Bush Hog 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 Bush Hog.
If you would like a VHS video tape of the video, please mail [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.
The information and material listed above along with this Operator’s Manual can assist you in meeting the OSHA
requirement for annual operator training.
OSHA TRAINING REQUIREMENTS
The following training requirements have been taken from Title 29, Code of Federal Regulations Part
1928.57 (a) (6). www.osha.gov
Operator instructions. At the time of initial assignment and at least annually thereafter the employer shall instruct
every employee who operates an agricultural tractor and implements in the safe operating practices and servicing
of equipment with which they are or will be involved, and of any other practices dictated by the work environment.

To the Owner/Operator/Dealer
This Operator's Manual is an integral part of the safe operation of this machine and must be maintained with the
implement at all times. A Manual canister is provided on the implement where this manual can be properly stored.
If you lose or damage this manual a free replacement manual can be obtained from an authorized Bush Hog dealer
or by down loading the manual from the Bush Hog website www.bushhog.com
BEFORE YOU START! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM
Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine
properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts
are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid
engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this
implement to be used with all its safety equipment properly attached to minimize the chance of accidents.
SAFETY FIRST. Completely read and understand the safety section of this manual before operating this
equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.
Contact your Dealer to explain any instructions that you do not fully understand.
The care you give your Bush Hog Implement will greatly determine your satisfaction with its performance and its
service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding
of your new implement and its intended use and service requirements.
All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of
forward travel with the implement properly attached to the tractor.
Replacement Parts information is located in a separate Parts Manual. Bush Hog 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 Bush Hog specifications. Non-genuine “will fit”
parts do not consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void
warranties, and present a safety hazard. Use genuine Bush Hog mower parts for economy and safety.
For future reference, record your Bush Hog product model number and serial number.
