<p>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.</p> |
