PROBLEM TO BE SOLVED: To provide a working vehicle designed to be automatically stopped by lifting working units 5 and 28 to nonworking positions and thereby to smoothly make its turning travel with reducing engine rotating speed drop attributable to the drive load of these working units. SOLUTION: The working vehicle has the following mechanism. As a first means, a statically hydraulic stepless variable-speed gear (47) that drives a traveling unit (2) is subjected to variable-speed actuation by the control of a variable-speed lever (S) and another statically hydraulic stepless variable-speed gear (76) that drives the working units (5 and 28) is subjected to automatic variable-speed actuation in association with lifting the working units (5 and 28) to nonworking positions. As a second means, additionally, the statically hydraulic stepless variable-speed gear (76) is subjected to variable-speed actuation by the control of a switch (119) furnished on the variable-speed lever (S).
