In Japan, especially in Hokkaido, productive large-scale farming is needed to keep a competitive power in market of domestic farm products against the low-cost farm products from foreign countries. To run the large-scaled farm, high working efficiency is needed to agricultural machinery. One of the way to make agricultural machinery work-efficient is to drive them faster than ever. But, vibration and postural instability is getting up, in proportion to the velocity of the vehicle. In this paper, deflective vibration control of the arm of boom sprayer and development of the mechanism to keep the arms of boom sprayer horizontal are shown. Measuring deflective vibration by acceleration sensors and using optimal regulator, deflective vibration of the arm can be kept down effectively. And designing the mechanism using CAE dynamics simulation in advance, development of the mechanism of posture control of the arms can be gone ahead smoothly.
