In this study, we developed three element technologies (HPS, roll-damper, and high-rigid slide boom) to reduce boom displacement. The three element technologies were placed in a vehicle for crop management. Two tests were performed (boom displacement reducing test, adhesion test), and the following results were obtained. In the boom displacement reducing test, the developed machine reduced the vertical boom displacement (full amplitude) by approximately 63% relative to the control machine (equipped with only high-rigidity slide boom). In the adhesion, the performance of the developed machine was similar to that of the control machine, even when the developed machine performed work at twice (1.0 m/s) the velocity of the conventional control machine. As we determined from the two tests, when equipped with the three devices, the machine reduced the vertical displacement of the boom, matching the performance levels of adhesion. Consequently, we concluded that the developed machine can work at a high velocity in the field.
