PROBLEM TO BE SOLVED: To provide a multistage transmission travel transmission device for a work vehicle in which, when temporarily stopping a work vehicle, the work vehicle is stably stopped by a simple operation of only a brake operation and which can be shifted to stable handling after the end of the brake operation.SOLUTION: In the multistage transmission travel transmission device for the work vehicle, main transmission devices (11, 12), a travel clutch (13) and a sub transmission mechanism (14) are provided in series. A travel motive force received from an internal combustion type mover part (4) can be transmitted to traveling wheels (2, 3) which can be braked in response to a brake operation. A detection switch (24s) is provided for the brake operation. Connection of the traveling clutch (13) is controlled to predetermined braking corresponding connection pressure (Pb) in response to the brake operation by the detection switch (24s), thereby performing stable machine body stop and subsequent stable shift. |
