PROBLEM TO BE SOLVED: To provide a combine-harvester in which the ground height of a reaping part is detected by a grounding body, and which can discriminate a detection state in which the ground height is detected by the grounding body from a storage state in which the grounding body is stored in a reaping part side, by the detection position of the grounding body.SOLUTION: A combine-harvester comprises: a reaping part 3 provided on a front part of the traveling vehicle body 2 thereof a grounding body 21 provided vertically swingably on the reaping part 3 and detection means 38 for detecting the swung position of the grounding body 21. In the combine-harvester: the grounding body 21 is switchable between a detection state in which the grounding body 21 is used to detect a ground height and a storage state in which the grounding body 21 is stored in a side of the reaping part 3 and the ground height of the reaping part 3 is detected by detecting the swung position of the grounding body 21 in the detection state by detection means 38. The combine-harvester further comprises: regulation means 39a, 62 which specify an upper limit to regulate upper swinging of the grounding body 21 in the detection state and holding means 54, 62 which hold the grounding body 21 in the storage state positioned upward of the upper limit position.COPYRIGHT: (C)2014,JPO&INPIT【課題】接地体により刈取部の対地高さを検出するコンバインにおいて、接地体を介して対地高さを検出する検出状態と、接地体を刈取部側に収納される収納状態とを、接地体の検出位置によって区別できるコンバインを提供することを課題としている。【解決手段】走行機体2の前部に設けた刈取部3に、上下揺動可能に取付けられた接地体21と、該接地体21の揺動位置を検出する検出手段38とを備え、前記接地体21を、対地高さを検出する検出状態と、刈取部3側に収納される収納状態とに切換え可能に構成し、検出状態の接地体21の揺動位置を検出手段38によって検知することにより、刈取部3の対地高さを検出するコンバインにおいて、検出状態で接地体21の上方揺動を規制して上限を定める規制手段39a,62と、該上限位置より上方側に位置させた収容状態で接地体21を保持する保持手段54,62とを設けた。【選択図】図4
