Development of Automatic Turn Over Device for Reversible Plow and Unmanned Tillage with Robot Tractor

─Visualization of Engine Output Distribution in the Field with CAN Data─

Abstract

　In this study, we developed an automated system for tillage using a reversible plow. The system uses some CAN data from the robot tractor. The experiment conducted 34 rows of unmanned tillage on a 0.8 ha experimental field. The estimated results of the amount of labor required per hectare (man-h/ha) showed that unmanned plowing using a robot tractor can reduce the amount of labor by 36 % compared with conventional manual plowing. In addition, we also proposed a method to visualize the engine power distribution of a robot tractor that can work continuously under certain conditions on a map to show changes such as soil hardness in a field in a simple and qualitative method.
