Evaluation of a Light Bar for Parallel Swathing Under Different Forward Speeds

The quality of ground application depends on a correct guidance. An equipment called light bar is replacing conventional guidance methods in parallel swathing. The purpose of this research was to evaluate the guidance accuracy of a Trimble © light bar model under different forward speeds. Results showed that the accuracy of the guiding system obtained with the light bar does not change significantly when the vehicle speed is increased from 1.39 m.s -1 (5.0 km -1 ) to 5.55 m.s -1 (20 km -1 ). Mean errors were similar at different distances between the rows. A 20 m distance was enough to align the vehicle.
