Evaluation of implement monitoring systems.

Author information

Department of Biosystems Engineering, University of Manitoba, Winnipeg, Manitoba, Canada.


During monitoring of rear-mounted equipment, frequent rearward turning of tractor drivers causes awkward postures that can cause musculoskeletal disorders related to the back, neck, and shoulders. The objective of this study was to compare three implement monitoring strategies (direct viewing via physical turning, indirect viewing via rear-view mirrors, and indirect viewing via a camera-monitor system) in a lab environment using a tractor and air seeder driving simulator Comparison was based on monitoring performance of the operator (i.e., response error), physical impact on the operator (i.e., head/neck acceleration and increase in neck muscle temperature), and operator preference. Indirect viewing via a camera-monitor system caused the least physical impact on subjects and was the preferred implement monitoring strategy. No significant differences (alpha = 0.05) in monitoring performance were observed.
