PROBLEM TO BE SOLVED: To devise arrangement of a reverse operation interlock mechanism including a reverse transmission mechanism performing reverse transmission of a reaping device and a reaping reverse lever operating the reverse transmission mechanism and the like, thereby achieving a compact reverse transmission mechanism without increasing a machine body width and facilitating maintenance.SOLUTION: The combine includes: a reaping processing part 8 reaping, conveying, and processing grain culms a threshing processing part 9 conveying and feeding reaped grain culms by a conveyance elevator 11 and threshing and processing the same and a steering operation part including a steering seat 12 arranged on a lateral side of the conveyance elevator of the reaping processing part. A reverse operation interlock mechanism including a reverse transmission mechanism 23 reversing a rotation direction of the reaping processing part 8, a reaping reverse lever 19 reversely operating the reverse transmission mechanism, and an operation interlock cable 21 is arranged on both sides sandwiching the conveyance elevator.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】刈取装置を逆転伝動する逆転伝動機構及びこれを操作する刈取逆転レバー等による逆転操作連動機構の配置を工夫し、機体幅を大きくせずに逆転伝動機構のコンパクト化並びにメンテナンスの容易化を図ること。【解決手段】本発明は、穀稈を刈り取って搬送処理する刈取処理部(8)と、刈取穀稈を搬送エレベータ(11)により搬送供給して脱穀処理する脱穀処理部(9)と、刈取処理部の搬送エレべータの横側に配置された運転席(12)とを含む運転操作部を備え、刈取処理部(8)の回転方向を逆転させる逆転伝動機構(23)と、この逆転伝動機構を逆転操作する刈取逆転レバー(19)及び操作連動ケーブル(21)とを含む逆転操作連動機構を前記搬送エレベータを挟んで左右両側に配設する。【選択図】図1
