Page 2 To the Owner/Operator/Dealer All implements with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded 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 accidents.
Page 3 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.
