FEATURE AT A GLANCE: The complexity of on-board equipment for farm tractors has grown dramatically in recent years, leading to significant changes in the operator's work situation. Today, most tractor functions are performed from inside the cabin, but little progress has been made toward reducing the risks associated with higher workloads. This article describes a methodology for designing a risk mitigation system for reducing rollover accidents. The methodology represents a combination of hierarchical task analysis and function allocation. Its implementation led to a final solution composed of visual and auditory displays and a joystick that gives force feedback in risky situations
