る構成のもので、次のような長所を備えている。 As is clear from the above description, the vehicle speed change device for the self-propelled work vehicle of this invention connects in series the main speed change device 6 that includes a reverse gear stage and the auxiliary speed change device 7 that only changes the vehicle speed. In a self-propelled work vehicle provided with
5, 27, 23, and 10, and the shift gears 26, 27 in the gear train are used as operating means 30 of the sub-transmission 7, and when the sub-transmission 7 is switched to the high speed side, the reverse gear stage is switched to the low speed side. It has the following advantages:
すなわち、この考案の車速変速装置は、上記の

せることとなつて、車速変速装置全体として得ら
れる後進車速が低速域に制限され、車輛が高速で
後進せしめられることがなくなつて、危険な事態
を避けさせる。 That is, since the vehicle speed change device of this invention is configured as described above, when the sub-transmission device 7 is switched to the high speed side, the reverse gear stage of the main transmission device 6 is always set to the low speed side. By obtaining reverse rotation, the reverse vehicle speed obtained by the entire vehicle speed changing device is limited to a low speed range, and the vehicle is not driven backward at high speed, thereby avoiding a dangerous situation.

巾が拡大されることとなる。 Furthermore, because the number of backward vehicle speeds that can be achieved in a low speed range is increased based on the above configuration, the vehicle speed change device of this invention is also advantageous in this respect. In other words, when the bucket is applied to soil, sand, or compost, as in a front loader, the vehicle is moved forward at low speed, and then when the vehicle is moved backwards and forwards, the bucket is not applied to the soil. When reversing, it is desirable for the vehicle to move backward relatively quickly, but according to the present device, which increases the number of reverse vehicle speeds in the low speed range, it is possible to move the vehicle backward in the low speed range where there is no danger in the above case. The range of options for reversing the vehicle is expanded, such as being able to reverse the vehicle at a relatively high speed.
