PROBLEM TO BE SOLVED: To perform spray liquid supply work to a chemical tank mounted in a rear part of a travel vehicle body in comfortable posture.SOLUTION: In a self-propelled pest control machine, an operation seat 4 where a worker is seated is arranged in a front part of a travel vehicle body 2 travelling with a front wheel 6 and a rear wheel 7, and a chemical tank 30 is mounted in a rear part. The self-propelled pest control machine can be switched between pest control work posture extending a pest control boom 40 arranged in a front part of the travel vehicle body 2 to the right/left and storage posture making the pest control boom along right/left side parts of the travel vehicle body 2. A boarding step 66L for a worker to rise/lower to/from the operation seat 4 is arranged in a side part of the travel vehicle body 2 between the front wheel 6 and rear wheel 7. Work steps 82B, 82R, 82L overhanging to a side part or rear part of the chemical tank 30 are arranged in a rear part of the travel vehicle body 2.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】本発明は、走行車体の後部に搭載する薬剤タンクへの噴霧液供給作業を楽な姿勢で容易に行えるように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の前部に作業者が着座する運転座席4を設けて後部に薬剤タンク30を搭載し、走行車体2の前部に設ける防除ブーム40を左右に伸ばした防除作業姿勢と走行車体2の左右側部に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、作業者が運転座席4に昇降するための搭乗ステップ66Lを前輪6と後輪7の間で走行車体2の側部に設け、該走行車体2の後部に薬剤タンク30の側部或いは後部に張り出す作業ステップ82B、82R、82Lを設けたことを特徴とする自走式防除機とする。【選択図】図4
