作業機における変速操作装置。 In a transmission device that is configured to have a transmission mechanism for switching between high and low speeds in a transmission case mounted on an agricultural machine, and to transmit power to an input shaft to the transmission case via an endless band, one The operating lever and the rotating arm of the tension roller that tensions the endless band are turned OFF when the operating lever is rotated in one direction, and the power is transmitted when the operating lever is rotated in the other direction. The operation lever and the operation shaft for switching the transmission mechanism between high and low positions are interlocked and connected via a second connection body so as to turn on the power. With the transmission turned on, the operating shaft is positioned at the low speed side, and when the operating lever is further rotated in the other direction, the operating shaft is rotated toward the high speed side. Gear shift operation device for agricultural machinery.
