To solve the conventional problem, there is a problem that the cutting device thrusts into the field in order to control the cutting height of the cutting device.SOLUTION: In a combine in which a hulling device 3 is provided on a machine frame 1 provided with a traveling device 2 and a reaper 4 is vertically adjustably provided by a reaper upper and lower cylinder 19, the reaper device 4 is supported by being grounded on the field surface A float 25 is provided and the ground wheel 40 and the float 25 are connected by a connecting frame 29. A supported member 51 externally fitted to the ground contact wheel 40 is provided with a square hole which is slidably fitted to the square pipe-And a single through hole 52 in the left-right direction are formed, and a plurality of through holes 53 are formed in the support member 50 along the rearwardly-upward inclination direction, the position of the supported member 51 is adjusted in the inclination direction of the support member 50 , A single pin 54 is inserted through one single through hole 52 and one of the plurality of through holes 53 and the position thereof is fixed, and the reaper device 4 is pushed up from the field surface of the float 25 or the ground wheel 40 Configuration and the combine to be saved toward.(FIG.【課題】従来のものは、刈取装置の刈り取り高さ制御のため、刈取装置が圃場に突っ込むという問題がある。【解決手段】走行装置2を備えた機体フレーム1上に脱穀装置3を設け刈取装置4を刈取上下シリンダ19によって上下調節自在に設けたコンバインにおいて、圃場面に接地して刈取装置4を支持するフロート25を設け、接地輪40とフロート25を連結フレーム29によって連結し、接地輪40に外嵌した被支持部材51には角パイプ状の支持部材50に対して摺動自在に嵌め合う角穴と左右方向の単一の貫通孔52が形成され、支持部材50には後上がり傾斜方向に沿って複数の貫通孔53を形成し、被支持部材51を支持部材50の傾斜方向に位置調節し、単一の貫通孔52と複数のうちのいずれかの貫通孔53に単一のピン54を挿通して位置固定し、フロート25または接地輪40の圃場面からの突き上げによって刈取装置4が上方へ退避する構成としたコンバイン。【選択図】図2
