PROBLEM TO BE SOLVED: To easily adjust a relative operation position of respective operation arms for operating a pair of transmissions for transmitting power for shifting to a pair of right and left crawler type travel devices. SOLUTION: This working vehicle is constituted so that link mechanisms 36A and 36B for mechanically connecting the operation arms 32A and 32B of the pair of right and left transmissions and a travel operation tool, are respectively and separately arranged with respective pairs of transmissions, and the respective link mechanisms 36A and 36B include a pair of connecting rods 44A, 44B, 46A and 46B and connecting links 47A and 47B for connecting the pair of connecting rods 44A, 44B, 46A and 46B, and respectively connect the pair of connecting rods 44A, 44B, 46A and 46B to the operation arm 32A, 32B side and the travel operation tool 23 side, and at least one of the pair of connecting rods 44A, 44B, 46A and 46B can be adjusted in the length. The two connecting links 47A and 47B are supported by a common fulcrum shaft 49. COPYRIGHT: (C)2011,JPO&INPIT
