PROBLEM TO BE SOLVED: To enable an operator to safely and easily operate a boom operation switch for boarding and unboarding to lift a pest control boom when boarding a traveling vehicle body.SOLUTION: A self-propelled pest control machine is given in which: a cabin 20 that an operator boards is arranged in the front part of a travelling vehicle body 2 travelling by front wheels 6 and rear wheels 7 and a chemical tank 30 is mounted in the rear part thereof and a pest control boom 40 arranged in the front part of the cabin 20 consists of a center boom 40a and side booms 40b, 40b which can be raised or laid on right and left sides of the center boom 40a. The self-propelled pest control machine can be switched between a pest control working posture where the side booms 40b, 40b are extended right and left and a stored posture where the side booms are laid along right and left side parts of the cabin 20 in a rearward lifted posture. A lifting and lowering switch 65a to lift and lower the pest control boom 40 is operably arranged between the side booms 40b, 40b that are stored in the sides of the cabin 20 and the cabin 20.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】作業者が走行車体に搭乗する際に防除ブームを上昇させる乗降用のブーム操作スイッチを安全に操作し易くすることを課題とする。【解決手段】前輪6と後輪7で走行する走行車体2の前部に作業者が搭乗するキャビン20を設けて後部に薬剤タンク30を搭載し、キャビン20の前部に設ける防除ブーム40をセンターブーム40aとセンターブーム40aの左右に屈曲起伏可能に設けるサイドブーム40b,40bで構成し、サイドブーム40b,40bを左右に伸ばした防除作業姿勢とキャビン20の左右側部に後上がり姿勢で沿わせた収納姿勢に切換え可能にした自走式防除機において、キャビン20の側部に収納したサイドブーム40b,40bとキャビン20の間に防除ブーム40を昇降する昇降スイッチ65aを操作可能に設けたことを特徴とする自走式防除機とする。【選択図】図8
