PROBLEM TO BE SOLVED: To prevent unexpected traveling during reaping operation in a state that traveling is stopped at the side of a levee etc. SOLUTION: A combine harvester is obtained by installing a reaping part 4 capable of carrying out non-stage gear shift of operation number of revolutions with a hydrostatic type infinite variable-speed transmission 21 for reaping and transporting in front of a traveling device 3 capable of carrying out the non-stage gear shift of traveling speed with a hydrostatic type infinite variable-speed transmission 12 for traveling, and installing a thresher 2 above the traveling device 3. In the combine harvester, the reaping part 4 is composed so that the infinite variable-speed transmission 21 for reaping and transporting is subjected to gear shift and driving synchronously with the traveling speed subjected to the gear shift by tilting operation of a main gear shift lever 13 of the infinite variable-speed transmission 12 for traveling installed in an operation part 6 which is provided with a reaping and driving ON and OFF means 53 for driving the reaping part 4 in the state that the traveling of the traveling device 3 with the infinite variable-speed transmission 12 for traveling is stopped.
