Improving Tractor Safety: A Comparison between the Usability of a Conventional and Enhanced Rear-Mounted Foldable...

Area of Science:

• Agricultural Safety
• Human Factors Engineering
• Mechanical Design

Background:

• Tractor rollovers are a primary cause of fatal and non-fatal agricultural injuries.
• Foldable rollover protective structures (FROPS) mitigate these risks but are often left folded down.
• Operator behavior regarding FROPS handling is influenced by human factors and technical design.

Purpose of the Study:

• To develop and evaluate an enhanced handling system for FROPS to improve user comfort and encourage proper use.
• To compare the usability of the enhanced FROPS handling system against a conventional system.

Main Methods:

• A prototype enhanced FROPS handling system was developed.
• Usability testing involved 93 novice tractor users performing lowering and raising tasks.
• Data collection included an ad hoc questionnaire (effort, time, posture, satisfaction) and observational analysis (effectiveness, efficiency).

Main Results:

• Participants reported significantly less perceived effort, physical discomfort, and time demand with the enhanced FROPS.
• Overall satisfaction was significantly higher when using the enhanced FROPS.
• The enhanced system eliminated critical usability issues observed with the conventional FROPS.

Conclusions:

• The developed enhanced handling system is usable and effective in improving FROPS operation.
• The system makes FROPS easier and safer for operators to use, potentially increasing their deployment and reducing rollover injuries.
• Addressing human factors in FROPS design is crucial for enhancing agricultural safety.
