PROBLEM TO BE SOLVED: To suppress shedding of crops with legume at the start of a machine body (mowing start) and also eliminate insufficient raking-in at the start of the machine body in harvesting rice or wheat, and to improve stability at the mowing start.SOLUTION: A general purpose combine 1 can harvest a plurality of crops and includes: a reel 12 provided in a mowing part 2 for mowing crops and raking in the crops in accordance with rotation drive and reel rotation control means for controlling the rotation speed of the reel 12 in linkage with vehicle speed and stopping the reel rotation at machine body stop. The reel rotation control means controls the reel rotation speed in linkage with the vehicle speed even at the machine body start when crops with legume such as soy beans are harvested, on the other hand, when rice or wheat is harvested, the reel rotation speed is increased to a predetermined rotation speed in response to the machine start, and then control is shifted in linkage with the vehicle speed at the predetermined speed or higher.COPYRIGHT: (C)2016,JPO&INPIT【課題】機体発進時(刈り始め)における莢物の脱粒を抑制するとともに、稲・麦を収穫する際には、機体発進時の掻込み不足を解消し、刈り始めの安定性を向上させる。【解決手段】複数種類の作物を収穫可能な汎用コンバイン1であって、作物を刈り取る刈取部2に設けられ、回転駆動に応じて作物を掻込むリール12と、リール12の回転数を車速連動制御し、機体停止時にリール回転を停止させるリール回転制御手段とを備え、リール回転制御手段は、収穫作物が大豆等の莢物のときは機体発進時においてもリール回転数を車速連動制御する一方、収穫作物が稲・麦のときは機体発進に応じてリール回転数を所定の回転数まで上昇させ、所定の車速以上で車速連動制御に移行する。【選択図】図25
