The utility model provides an operation vehicle. The operation vehicle is provided with an input shaft (20) used for receiving power of an engine, a transmission shaft (45) used for receiving power of the input shaft (20), and a running output shaft (49) used for receiving and outputting power of the transmission shaft (45), wherein a plurality of first variable gears (28 and 29) and a plurality of second variable gears (31, 32 and 33) are arranged on the input shaft (20) a first variable-speed setting gear (35) used for selecting any one of the plurality of first variable gears (28 and 29) and a second variable-speed setting gear (36) used for selecting any one of the plurality of second variable gears (31, 32 and 33) are arranged on a variable-speed adjusting shaft (34) which is arranged in parallel to the input shaft (20), so that a structure that the first variable-speed setting gear and the second variable-speed setting gear (36) can slide relative to the variable adjusting shaft can be formed. According to the operation vehicle, the transmission structure of the operation vehicle becomes simple.
