PROBLEM TO BE SOLVED: To reduce the weight of a transmission case at low cost, in a combine-harvester provided with a shift transmission device including a static hydraulic type non-stage shift unit performing shift by inputting driving force from an engine and a planetary transmission unit synthesizing the driving force from the engine and output of the non-stage shift unit and outputting synthetic driving force to a travel device.SOLUTION: A non-stage shift case unit 95 storing a non-stage shift unit 40 among a transmission case 35 is integrally formed with a planetary transmission case unit 96 storing a planetary transmission unit 50 among the transmission case 35. A partition wall 97 partitioning a non-stage shift chamber 95A storing the non-stage shift unit 40 of the non-stage shift case unit 95 and a planetary transmission chamber 96A storing the planetary transmission unit 50 of the planetary transmission case unit 96 is included inside the transmission case 35. |
