The problem addressed by the present invention is to provide a tractor that can easily constitute different models and improve workability for design, fabrication, and the like. A tractor to which a working implement is raisably and lowerably attached to a moving machine body (2) is provided with the moving machine body (2) in which an engine (5) is mounted, a link mechanism (111) for attaching a work implement to the moving machine body (2), and a raising and lowering mechanism (22) for raising and lowering the link mechanism (111), with part of the moving machine body (2) being constituted of a transmission case (17), part of the link mechanism (111) constituted of lower links (23), and part of the raising and lowering mechanism (22) constituted of a lift cylinder (117). The structure is such that the base end sides of the left and right lower links (23) are linked to the transmission case (17) via lower link support shaft bodies (130), and a hitch body (131) is provided attachably and detachably on the outside of the side surface part or the outside of the bottom surface part of the transmission case (17). The left and right lower link support shaft bodies (130) are provided on the left and right side parts of the hitch body (131), and the constitution is such that the base end sides of the left and right lower links (23) are supported via the left and right lower link support shaft bodies (130) on the left and right side parts of the hitch body (131).
