STUDY AND RECOMMENDATIONS FOR THE REDUCTION OF MOWER-THROWN-OBJECT ACCIDENTS. FINAL REPORT
There has been a significant number of insurance claims againt the Texas State Department of Highways and Public Transportation involving mower-thrown-object accidents. This report details the efforts made to reduce the number of mower-thrown-object accidents and discusses possible changes in mowing standards, available mowing equipment, and possible design modifications to mowers. Ideas and theories are tested and evaluated experimentally using a Terrain King TK 15-IV bat-wing mower. The experiments were conducted to determine the relative safety of several types of safety devices. The experiments also served the purpose of determining where objects leave the mower. From the experimental results several conclusions were made. Most of the objects exit the rear of the mower and safety devices such as chains and cables improve the safety of the mower. Finally recommendations were made from the experiments and from the observations. The most important of these recommendations is that a canvas guard be added to the rear of the mower and a reduced mass cutting blade be further tested. In addition, the report discusses the background of mower-thrown-object accidents, blade design, possible application of alternative materials for blades, conclusions, and recommendations.
