Development of the Safe Tractor Assessment Rating System.

Area of Science:

• Agricultural Safety and Health
• Occupational Safety Engineering
• Product Safety Assessment

Background:

• Tractor-related injuries and fatalities remain a significant concern in agriculture.
• Existing safety assessments often lack a comprehensive, design-focused approach.
• There is a need for an objective system to evaluate the inherent safety of tractor designs.

Purpose of the Study:

• To develop and validate the Safe Tractor Assessment and Rating System (STARS).
• To create a design-based, objective rating system for tractor safety features.
• To inform manufacturers, dealers, and users about tractor injury risk management.

Main Methods:

• Developed a predictive rating system model based on technical inspection.
• Incorporated current standards, research, injury data, and farmer input.
• Utilized an iterative development process with field, pilot, and inter-rater reliability testing.
• Structured the system into six domains: rollover, runover, user, information/controls, pedestrian protection, and options.

Main Results:

• STARS effectively differentiates between older and newer tractor models based on inherent safety.
• The system assigns star ratings (0-5) for six safety domains.
• Scores reflect the potential of design features to prevent or mitigate injury events.

Conclusions:

• STARS offers a valuable tool for assessing and improving tractor safety.
• The system can guide the design and selection of tractors with enhanced safety features.
• STARS is being implemented in Australian technical education and training programs.
