This study investigated the extent, causes, and means of preventing agricultural tractor accidents. The report includes an estimate of annual tractor-related deaths, an identification of the primary causes of such accidents with consideration of the major hazards causing death or injury, and recommendations or means for preventing the occurrence of and reducing the severity of injuries resulting from tractor accidents. Because of recent private initiative in tractor safety, Federal safety standards are not considered necessary at this time. Alternative recommendations include: (1) The tractor industry should intensify efforts to promote and market equipment with proper safety equipment, (2) The insurance industry should consider the feasibility of incentives for farm operators to choose safety features, and (3) States should require driver's licenses for operating tractors on public roads and should develop adequate accident reporting systems which will contribute to hard data for further research.
