To set a running vehicle body to an appropriate height from the ground according to a growing state or type of a crop, a working state, etc., while enabling satisfactory rotating drive and a swivel operation of a running wheel.SOLUTION: Power of an engine is transmitted to a running wheel S via a lateral transmission shaft 15 and a longitudinal transmission shaft 20, the running wheel S is supported so as to be changeable in position around the rotation axis Y of the longitudinal transmission shaft 20, the longitudinal transmission shaft 20 and a longitudinal transmission case 19 each can be extended/shortened while sliding. Thus, a double structure having inside and outside is configured. The longitudinal transmission case 19 is supported so as to be rotatable integrally with the running wheel S. A vehicle height adjustment mechanism 43 is provided in which the height of the running wheel S relative to a vehicle body frame can be switched to a plurality of steps by extending/shortening the longitudinal transmission shaft 20 and the longitudinal transmission case 19.SELECTED DRAWING: Figure 7

    【課題】走行車輪の回転駆動と旋回操作とを良好に行えるようにしながら、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】エンジンの動力が横向き伝動軸15及び縦向き伝動軸20を介して走行車輪Sに伝達され、走行車輪Sが、縦向き伝動軸20の回転軸芯Y周りで向き変更可能に支持され、縦向き伝動軸20及び縦向き伝動ケース19の夫々が摺動しながら伸縮可能な内外二重構造に構成され、縦向き伝動ケース19が、走行車輪Sと一体的に回動可能に支持され、縦向き伝動軸20、及び、縦向き伝動ケース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車高調節機構43が備えられている。【選択図】図7
