PROBLEM TO BE SOLVED: To detect a vertical direction position of a reel without using an expensive stroke sensor.SOLUTION: A reel 4 is rotatably supported in a front end part of a combine-harvester, and a reel support arm 38 is swung in a vertical direction by a lifting cylinder 41 to adjust a vertical direction position of the reel 4. An end part of an outer wire 90a is attached to a cylinder part 41a of the lifting cylinder 41, and an inner wire 90b is connected to the reel support arm 38. A potentiometer 91 is disposed on a back plate 8a of a reaping frame 8, and a stroke of the lifting cylinder 41 is transferred to the potentiometer 91. |
