PROBLEM TO BE SOLVED: To provide a combine-harvester that can exhibits various appropriate traveling speeds and can prevent wrong operation of an operational tool by a driver, while forming a compact transmission case by minimizing an increase of parts count and a space.SOLUTION: A harvester includes: a main transmission for shifting a drive force from an engine into forward/reverse stepless stages; a gear-type sub-transmission internally packaged in a transmission case and shifting the drive force that is output from the main transmission into multiple stages according to a working state and transmitting it to a traveling device; a main transmission operation tool 41 shifting the stages of the main transmission; a clutch operation tool 43 for performing on/off operation of a work clutch; and a check mechanism 45 for checking the main transmission operation tool 41 from being operated to the speed increase side rather than a predetermined command position in a forward side operation path 24a, when the work clutch is operated. |
