Becker, professor emeritus; Agricultural and Biological Engineering Department, Institute of Food and Agricultural Sciences, University of Florida, Gainesville, 32610. Florida agriculture, including forestry and fishing, made an annual economic impact of $55 billion in 1998, according to the Florida Department of Agriculture and Consumer Services. More than 81,000 people work on the 40,000 farms in the state, and more than 50,000 are employed in other activities related to agriculture. The state's agricultural enterprises range from large citrus, vegetable and cattle operations to small family-operated farms. From 1989 to 1998, there were approximately 240 deaths related to agriculture in Florida, according to data compiled by the Deep-South Agricultural Health and Safety Center. In addition, agriculture has one of the highest injury and death rates among U.S. industries. Safety in Florida agriculture is challenging because: Florida agricultural enterprises are diverse, safety knowledge among workers varies, manual labor is used extensively, the climate creates year-round heat stress. Therefore, it is vital to assist the public in learning about federal occupational safety and health (OSHA) documents related to agriculture.

This label implies either that information has been deleted from the previous version of the standard or that additions to the standard are anticipated. Because standards often reference other standards, it is important that paragraph numbers remain consistent. Agricultural tractor -A twoor four-wheel-drive type vehicle, or track vehicle, of more than 20 engine horsepower, designed to furnish the power to pull, carry, propel, or drive implements that are designed for agriculture. All self-propelled implements are excluded. Low profile tractor -A wheeled tractor possessing the following characteristics: The front wheel spacing is equal to the rear wheel spacing, as measured from the centerline of each right wheel to the centerline of the corresponding left wheel. The clearance from the bottom of the tractor chassis to the ground does not exceed 18 inches. The highest point of the hood does not exceed 60 inches, and The tractor is designed so that the operator straddles the transmission when seated. Tractor weight -Includes the protective frame or enclosure, all fuels, and other components required for normal use of the tractor. Ballast shall be added as necessary to achieve a minimum total weight (tractor and ballast) of 110 lb. (50.0 kg.) per maximum power take-off horsepower at the rated engine speed or the maximum, gross vehicle weight specified by the manufacturer, whichever is the greatest. Front-end weight shall be at least 25 percent of the tractor test weight. In case power take-off horsepower is not available, 95 percent of net engine flywheel horsepower shall be used. Agricultural tractors manufactured after October 25, 1976, shall meet the following requirements: 1928.51(b)(1) -Roll-Over Protective Structures (ROPS). A roll-over protective structure (ROPS) shall be provided by the employer for each tractor operated by an employee. Except as provided in paragraph (b)(5) of this section, ROPS used on wheel-type tractors shall meet the test and performance requirements of: the American Society of Agricultural Engineers (ASAE) Standard S306.3-1974 entitled "Protective Frame for Agricultural Tractors -Test Procedures and Performance Requirements" and Society of Automotive Engineers (SAE) Standard J334-1970, entitled "Protective Frame Test Procedures and Performance Requirements" (formerly codified in 29 CFR 1928.52); or ASAE Standard S336.1-1974, entitled "Protective Enclosures for Agricultural Tractors -Test Procedures and Performance Requirements" and SAE J168-1970, entitled "Protective Enclosures -Test Procedures and Performance Requirements" (formerly codified in 29 CFR 1928.53)(1); or
Roll-Over Protective Structures (ROPS) for Tractors Used in Agricultural Operations --.... 3 1926.1002 of the OSHA construction standards. These ASAE and SAE standards are incorporated by reference and have been approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from either the American Society of Agricultural Engineers, 2950 Niles Road, Post Office Box 229, St. Joseph, MI 49085, or the Society of Automotive Engineers, 485 Lexington Avenue, New York, NY 10017.
