PROBLEM TO BE SOLVED: To provide a combine-harvester for reducing an operation load on the operator, when an artificial operation is performed to drive a cutting part B by a forced raking-in, and for preventing the useless drive of the cutting part B and the culm drop or the chipping impossible state, so that it can perform a cutting operation efficiently.SOLUTION: A speed changer 29 for a cutting part B to carry the grain culm cut out is controlled so that the driving speed of the cutting part B may synchronize with the running speed of the machine body. In the case where a forced raking-in command is once issued by a manual operation 18 during the advance of the machine body, the driving speed of the cutting part B is regulated not to become lower than a preset forced raking speed.SELECTED DRAWING: Figure 10 |
