Evaluation of a Light Bar for Parallel Swathing Under Different Forward SpeedsPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Pp. 190-195 in Proceedings of the World Congress of Computers in Agriculture and Natural Resources (13-15, March 2002, Iguacu Falls, Brazil) 701P0301.(doi:10.13031/2013.8329)Authors: J.P.

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. (Download PDF) (Export to EndNotes)
