PROBLEM TO BE SOLVED: To solve problems that sharp turning when turning at a headland is difficult to be performed caused by becoming the whole length of a machine body to be long in conventional working machines, and when the machine body inclines during working, a reaping blade unit can not be horizontally held to cause cut heights of adjacent crops to be irregular.SOLUTION: The working vehicle is constituted by installing a top-pruning operation device 12, equipped with a hair clipper type blade 10 for cutting the tip portions of crops while self travelling and a motor 11 for driving the hair clipper type blade 10, to be supported in a state of being hung just below the front part of a lifting link mechanism 8 portion capable of lifting and lowering and installed in the front part of a travelling vehicle 1, wherein the top-pruning operation device 12 is installed to be able to control lateral rolling around the center of a longitudinally directed rolling shaft 19 mounted on the lifting link mechanism 8 portion.COPYRIGHT: (C)2011,JPO&INPIT【課題】本発明の課題は、従来のものでは、機体の全長が長くなって枕地旋回での小回りが効きにくくなる問題、また、作業中、機体が傾くと、刈刃部が水平に維持できないため、隣接する作物の切断高さが不揃いとなる問題を解消することにある。【解決手段】本発明は、自走しながら作物の先端部を切断処理するバリカン式刈刃10と、このバリカン式刈刃10を駆動する原動機11を備えた摘心作業装置12を、走行車体1の前部に装着された昇降可能な昇降リンク機構8部の前部直下に吊り下げ状態に支持させて設け、該摘心作業装置12は、前記昇降リンク機構8部に架設された前後方向のローリング軸19芯周りに左右ローリング制御可能に装備してあることを特徴とする作業車両の構成とする。【選択図】図1
