Vertical and horizontal oscillation of three models of self-propelled boom sprayers

ABSTRACT The spray boom is one of the sprayer components that most affect the application quality and may cause phytotoxicity and overlay application problems. Therefore, this study aimed to evaluate the displacement in the vertical and horizontal movements of the spray booms in three models of self-propelled boom sprayers. The vibrations of the spray boom in the vertical direction was measured using three receivers (GNSS) with RTK differential correction. The vibration measurements in the horizontal direction were determined using a high resolution camera. At the end, the processed data were entered into a spreadsheet for the descriptive statistics. The smallest spray boom movement in the horizontal direction was obtained by the specimen 2. No statistical differences were observed between the different speeds for the spray boom vibration in the horizontal and vertical directions, in the evaluated sprayers. The largest vertical movements of the spray booms were observed for the self-propelled specimen 3. The impact/collision route type showed the highest deviations and, in undulating and gentle to undulating types, there was no significant difference in deviation values.
