という欠点がある。[Problems to be Solved by Prior Art and Invention] In general, a driver's seat attached to a work vehicle of this type can be adjusted to move back and forth according to the size of the operator. Conventionally, however, the front-back movement of the driver's seat has been such that it moves almost horizontally when the operator is seated, so if a person with a small size moves the driver's seat forward to try to drive, the driver's steering wheel will move. There is a drawback in that it will be in a state where it will be positioned exactly on the chest, and this will force an unreasonable posture for handling operations.

ものがある。Therefore, a so-called chilled handle system that allows the driver to swing up and down can be adjusted to accommodate the seat position. However, in this case, the structure is not allowed to be complicated, and the handle is adjusted each time the seat position is adjusted. Due to the complexity of having to adjust the height, the reality is that the height of the steering wheel is practically not adjusted, and for people with a small physique, the front view is not wide open. There is also a drawback. In order to solve the above-mentioned problems, for example, as shown in Japanese Utility Model Laid-Open No. 61-25234, a seat is provided so as to be movable in the front-rear direction along a guide rail, and the guide rail is compared to the front in the rear. In some cases, the seat height can be adjusted by adjusting the movement of the seat in the front-rear direction by arranging the seat on the floor so as to be in a high position via an inclined base.

た。However, even if this structure can be adopted for an automobile that only adjusts the seat height of the driver's seat, a structure in which a pivotal support part such as an operation lever is arranged is utilized by utilizing the lower position of the front end of the driver's seat. It has been difficult to use it as it is for a general traveling vehicle such as a general agricultural tractor.

る。[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised with the object of providing an agricultural tractor with a driver seat position adjusting device that can eliminate these drawbacks. The guide rails that are integrally laid on the upper surface of the seat bracket that supports the driver's seat provided in the driver's control section allows the driver to adjust the movement in the front-rear direction. In a working vehicle in which the seat bracket is configured to have a front height and a rear height so as to be higher, the seat bracket is disposed at a predetermined interval on an upper surface of a transmission case provided below the driver seat. A seat bracket that protrudes forward from a lower rear portion of a seat portion of the driver seat to a front end portion of the transmission case, and A front space surrounded by the cover member, the front end of the seat bracket, and the front end of the transmission case, which is configured to be close to the lower surface of the front part of the seat portion and has a cover member vertically extending from the front end of the seat bracket. In addition, a base end portion of an operation lever that protrudes forward from the cover member and that can be operated in the vertical direction is disposed and pivotally supported.
