To provide a travel transmission device of a tractor which can obtain a tractor capable of driving wheels at a speed and torque suitable for work.SOLUTION: A travel transmission device comprises a change gear 18, a forward/backward switching device 19 for converting the output of the change gear 18 into forward power and backward power, a rear wheel differential mechanism 20 for inputting the output of the forward/backward switching device 19 to transmit it to the rear wheel 7, and a gear transmission mechanism 95 for transmitting power of an output shaft 91 of the forward/backward switching device 19 to an input shaft 20a of the rear wheel differential mechanism 20. A transmission case 3 is configured to be divisible into a front case part 3A accommodating the change gear 18 and a rear case part 3B accommodating the forward/backward switching device 19, the rear wheel differential mechanism 20, and the gear transmission mechanism 95. The gear transmission mechanism 95 is detachably provided in a portion of the inside of the transmission case 3, which corresponds to a front end portion 3C of the rear case part 3B.SELECTED DRAWING: Figure 2
