... is selectively actuated by a control valve 21 using pressure oil supplied from a hydraulic pump 23 to perform multi-stage gear shifting. This work vehicle is equipped with a gear shaft-type sub-transmission device 16 for manually operating a multi-speed gear shift on the upper side, and a travel clutch 11 that can be manually input operated on the transmission upper side of the sub-transmission device 16. In the traveling transmission, the hydraulic circuit a of the main transmission 17 is connected to the auxiliary transmission 16.
A traveling transmission device for a work vehicle, which is provided with a valve 28 that is placed in an unload state during an artificial speed change operation, and placed in a load state after the manual speed change operation is completed. The hydraulic pump 23 is connected to the traveling clutch 1.
1. A travel transmission device for a working vehicle according to claim 1, which is interlocked and connected to the transmission system on the downstream side of the first transmission.
