PROBLEM TO BE SOLVED: To provide a tractor capable of sliding a moving side supporting piece in a stretching /loosing direction by operating a slide adjusting piece, and easily carrying out tension adjustment (tension adjustment) of an interlocking belt. SOLUTION: A hydraulic pump for driving various hydraulic actuating means is provided through a supporting element, and the interlocking belt is wound between an input shaft of the hydraulic pump and an input shaft of a transmission portion. The supporting element comprises a fixed side supporting piece, the moving side supporting piece capable of sliding in the stretching/loosing direction of the interlocking belt on the fixed side supporting piece and supporting the hydraulic pump, a slide-adjusting piece interposed between the moving side supporting piece and the fixed side supporting piece and slide-adjusting the moving side supporting piece, and a position adjusting piece interposed between the moving side supporting piece and the fixed side supporting piece positioned in sides of the slide adjusting piece and adjusting disarrangement of a position of the moving side supporting piece at the time of slide actuation. The position adjusting piece is disposed in the other side of the interlocking belt side wound around the input shaft of the hydraulic pump across the slide-adjusting piece.
