The Condition of Agricultural Driveline System Shielding and Its Impact on Injuries and Fatalities

  • Campbell, William P.


The primary goal of this project was to investigate the current hazards associated with power take-off components and to develop recommendations to help reduce power take-off related injuries and deaths.

In order to achieve this goal, the following activities were conducted:

  • Data from power take-off accidents was collected and summarized to determine factors associated with power take-off accidents.
  • A review of literature related to the power take-off was conducted to document the progress made toward improving the safety of power take-off components.
  • An investigation of the hazards of the power take-off driveline was conducted by surveying the condition of driveline shielding components on used agricultural implements.
  • The condition of the power take-off related safety signs on used implements was investigated to determine their durability.
  • An audio-visual presentation was produced that was aimed at agricultural equipment operators and dealt with the safe use and maintenance of power take-off drivelines.
  • Recommendations for farmers, safety leaders and equipment manufacturers were developed to help prevent power take-off accidents.

Accident investigations summarized in this study include 100 non-fatal power take-off accidents, and 25 fatal power take-off accidents. Absence of shielding at the area of entanglement, the presence of a protrusion on the driveline, and the actions of the victim were all factors contributing to the majority of the accidents investigated.

The condition of the safety signs and shielding components for the power take-off driveline for 1309 machines was investigated for this study. There were no readable power take-off related safety signs on 45 percent of the implements surveyed. Damaged or missing shielding was found on 40.1 percent of the implement input drivelines, 37.5 percent of the implement input connections, and 23.8 percent of the pedestals on the implements in the sample.
