To provide a working vehicle which can reduce damage caused to a worked surface in turning.SOLUTION: A working vehicle includes a traveling vehicle body, a working machine, a 4WD clutch, and a control part. The traveling vehicle body has a pair of right and left front wheels and rear wheels as driving wheels. The working machine is mounted on the traveling vehicle body and performs a work for a worked surface during traveling of the traveling vehicle body. A hydraulic 4WD clutch switches the traveling vehicle body between 2WD traveling with only the front wheels or the rear wheels as the driving wheels and 4WD traveling with the front wheels and the rear wheels as the driving wheels by connection/connection release. The control part controls the 4WD clutch, and switches the traveling vehicle body to the 2WD traveling in turning during the 4WD traveling of the traveling vehicle body.SELECTED DRAWING: Figure 5 【課題】旋回時において被作業面に与えるダメージを低減させることができる作業車両を提供すること。【解決手段】作業車両は、走行車体と、作業機と、４ＷＤクラッチと、制御部とを備える。走行車体は、駆動輪となるそれぞれ左右一対の前輪および後輪を有する。作業機は、走行車体に装着され走行車体の走行中に被作業面に対する作業を行う。油圧式の４ＷＤクラッチは、前輪のみまたは後輪のみが駆動輪となる２ＷＤ走行、前輪および後輪が駆動輪となる４ＷＤ走行を接続／接続解除によって切り替える。制御部は、４ＷＤクラッチを制御するとともに、走行車体が４ＷＤ走行中における旋回時には走行車体を２ＷＤ走行に切り替える。【選択図】図５
