To smoothly set a running vehicle body to an appropriate height from the ground according to a growing state or type of a crop or a working state, without troublesome labor.SOLUTION: A running wheel S is supported by a vehicle body frame via a cylindrical support member 19 extending in a vertical direction, the support member 19 is configured so as to be extended/shortened in a vertical direction, the height of the running wheel S relative to the vehicle body frame can be switched to a plurality of steps by extending/shortening the support member 19, thus providing a vehicle height adjustment mechanism 43 of hydraulic operation system. The vehicle height adjustment mechanism 43 is provided with a plurality of hydraulic cylinders 44 extending in the direction in which the support member 19 is extended/shortened. The plurality of hydraulic cylinders 44 are arranged in different positions in a circumferential direction on the outer periphery side of the support member 19 and opposite with the support member 19 between them.SELECTED DRAWING: Figure 7

    【課題】煩わしい手間を掛けることなく且つ円滑に、作物の生育状態や作物の種類の違い又は作業状況の違い等に応じて、走行車体の地上高を最適な高さに設定できるようにすることが望まれていた。【解決手段】走行車輪Sが、上下方向に延びる筒状の支持部材19を介して車体フレームに支持され、支持部材19が、上下方向に伸縮可能に構成され、支持部材19を伸縮操作して走行車輪Sの車体フレームに対する相対高さを複数段階に切り換え可能な油圧操作式の車高調節機構43が備えられ、車高調節機構43に、支持部材19の伸縮方向に沿って延びる複数の油圧シリンダ44が備えられ、複数の油圧シリンダ44は、支持部材19の外周側において周方向に異なる位置であって且つ支持部材19を挟んで対向する位置に配置されている。【選択図】図7
