PROBLEM TO BE SOLVED: To provide a working vehicle eliminating such a problem that things such as cut-off stems and leaves are left on the cutting blade to effect declining in the working vehicles performance.SOLUTION: The working vehicle includes: a cutting blade 10 for pinching use in the front of the vehicle body 1 to make a cutoff treatment of the tip of a crop under self-propelled motion and a blowing means 27 at an appropriate position on the vehicle body to blow forced air onto the cutting blade 10 to exclude cut-off things. In the working vehicle, it is characterized that the blowing means enables pinching operation to be conducted while blowing air onto the whole surface of the cutting blade 10 from the rear of the cutting blade toward the front thereof and over the whole surface of the cutting blade.COPYRIGHT: (C)2011,JPO&INPIT【課題】本発明の課題は、切断された茎葉などの被切断物が刈刃上に残留し、切断性能を低下させる問題を解消することにある。【解決手段】車体1の前部に自走しながら作物の先端部を切断処理する摘心作業用刈刃10を装備し、車体適所には前記摘心作業用刈刃10の刈刃上に強制風を吹き付けて被切断物を排除する送風手段27を設けてあることを特徴とする作業車両の構成とする。また、前記送風手段は、摘心作業用刈刃10の刈刃の全面にわたり刈刃後方より前方に向けて且つ刈刃の全面にわたって送風しながら摘心作業が行えるように構成してあること特徴とする作業車両の構成とする。【選択図】図2
