PROBLEM TO BE SOLVED: To constitute a compact transmission dispensing with a reverse steering preventive mechanism of complicated structure regarding the transmission for a combine comprising a traveling HST (hydrostatic transmission) changing speed of traveling power, and a turning HST changing speed of turning power, transmitting the output rotation of the traveling HST to right and left crawler travel devices in straight advancing travel, and combining and transmitting the output rotation of the traveling HST and turning HST to the crawler travel device on the turning inside in turning travel. SOLUTION: Each of the traveling HST 16 and the turning HST 17 are formed as an integrated type integrally formed with a hydraulic pump and a hydraulic motor, and the traveling HST 16 is arranged on the right side of the transmission 14, while the turning HST 17 is arranged on the left side from the top view. The output rotation of the hydraulic motor 16b of the traveling HST 16 is transmitted to the hydraulic pump 17a of the turning HST 17. COPYRIGHT: (C)2008,JPO&INPIT
