PROBLEM TO BE SOLVED: To stabilize the operation of a reaping part which is driven via a static hydraulic continuously variable transmission and a planetary gear mechanism.SOLUTION: A planetary gear mechanism (70) is arranged between an output shaft (38) of a static hydraulic continuously variable transmission (21) which is driven by an engine (22) and a reaping output shaft (45A) which outputs a drive force to a reaping part (4), and the rotation of the output shaft (38) of the static hydraulic continuously variable transmission (21) and the rotation of an input shaft (37) of the static hydraulic continuously variable transmission (21) are synthesized by the planetary gear mechanism (70), and outputted from a reaping output shaft (45A). Furthermore, the planetary gear mechanism (70) forwardly rotates the rotation of the output shaft (38) from reverse rotation via zero-rotation, and transmits it to the reaping output shaft (45A). A one-way clutch (80) for preventing the transmission of the reverse rotation to the reaping part (4) is arranged between the reaping output shaft (45A) and a reaping output pulley (45) which is arranged at the reaping output shaft (45A). |
