PROBLEM TO BE SOLVED: To provide an operation part structure of a harvester capable of changing the height of the driver's seat as well as its attitude. SOLUTION: A front 11 and a rear supporting arm 12 are coupled with a seat support 7 in such a way as capable of swinging in rising and falling. The front support arm 11 is coupled with the front extremity of the driver's seat 2, and when changing-over is made into the falling condition, the front extremity of the driver's seat 2 is pulled down and supported at the low installation level relative to the seat support 7, and when changing-over is made into the rising condition, the front extremity of the driver's seat 2 is pulled up and supported at the high installation level relative to the seat support 7. When the rear support arm 12 is changed over into the rise working condition, it abuts to a placing part 32 at the rear end of the driver's seat 2 or is engaged with an engagement part 33, and the rear end of the driver's seat 2 is received at the high installation level relative to the seat support 7 and supported. When the rear support arm 12 is changed over into the fall disengage condition, a receiving part 14 of the seat support 7 receives the rear end of the driver's seat 2 at the low installation level relative to the seat support 7 and supports it there.
