PROBLEM TO BE SOLVED: To provide a combine-harvester, in which the tramp and tension of a crawler can prevent slackness.SOLUTION: A back side support rolling wheel (51) abuts against the rear inner face of an ungrounded portion of a crawler (34), while an airframe frame (1) being positioned in a state from the lowest vehicle position to the highest vehicle position. A front support rolling wheel (41) abuts against the front part inner face of the ungrounded portion of the crawler (34) in a state in which the airframe frame (1) is positioned in a state from the lowest vehicle position to an intermediate vehicle position between the lowest vehicle position and the highest vehicle position, and the front support rolling wheel is spaced downward from the front part inner face of the ungrounded portion of the crawler (34) in a state in which the airframe frame (1) is positioned in a state between the intermediate vehicle position and the highest vehicle position.SELECTED DRAWING: Figure 4
【課題】クローラのばたつき、緊張が弛みを防止できるコンバインを提供する。【解決手段】後側支持転輪(51)は、機体フレーム(1)が最低車高位置から最高車高位置に亘る位置にある状態においてクローラ(34)の非接地部の後部内面に当接し、前側支持転輪(41)は、機体フレーム(1)が最低車高位置から最低車高位置と最高車高位置の間の中間車高位置にある状態においてはクローラ(34)の非接地部の前部内面に当接し、機体フレーム(1)が中間車高位置から最高車高位置に亘る位置にある状態ではクローラ(34)の非接地部の前部内面から下方へ離間する構成とした。【選択図】図4
