PROBLEM TO BE SOLVED: To provide a tractor which increases the attaching work efficiency of hydraulic piping. SOLUTION: A hydraulic pump 240 is interlocked and connected with a prime mover section which is arranged in the front section of the machine body. In the meantime, a hydraulic equipment for elevation is provided in the upper section of a mission section 4 which is arranged in the rear section of the machine body, and the hydraulic piping 241 is inserted between the hydraulic equipment for elevation and the hydraulic pump 4 for the tractor. The hydraulic piping 241 is formed of a high-pressure feeding pipe 242 which feeds an operating oil from the hydraulic pump 240 to the hydraulic equipment for elevation at a high-pressure, and a low-pressure returning pipe 243 which returns the operating oil from the hydraulic equipment for elevation to the hydraulic pump 240 at a low pressure. The high-pressure feeding pipe 242 and the low-pressure returning pipe 243 are arranged to be proximal on one side of the machine body. Therefore, the attaching work for those pipes can simultaneously be performed on one side of the machine body, and the attaching work efficiency can be increased. COPYRIGHT: (C)2006,JPO&NCIPI
