Abstract: A tractor includes a link mechanism and a power extractor. The link mechanism includes a top link, a right lower link, and a left lower link. A work apparatus is connectable to the link mechanism to move the work apparatus upward and downward. The power extractor is connectable to a power input of the work apparatus to take power from a power source and supply the power to the work apparatus. The power extractor is located at a position lower than a lowest position of the right lower link and a lowest position of the left lower link.

Abstract: A loading work apparatus includes booms, attachment tools, an implement tool removably attached to the attachment tools, and implement tool cylinders. The implement tool includes an engaged member on a back surface thereof. The attachment tools include an attachment unit having an engaging member engaged with the engaged member, coupling members supporting the transverse shaft, and lock members locking/unlocking engagement between the engaging member and engaged member. Each coupling member includes brackets on lateral opposite sides of the lock member. The transverse shaft is supported at opposite ends thereof by lower portions of the right and left brackets. The support shaft is supported at opposite ends thereof by intermediate portions of the right and left brackets. The transverse shaft and the support shaft bridge across the lock member.

Abstract: A front loader includes a mechanical posture maintaining mechanism for maintaining the posture of an implement, regardless of swing displacement of a boom. The boom is formed in a curved shape in which a longitudinal central side thereof is located above. The posture maintaining mechanism includes a swing link member having an inner free-end part and an outer free-end part and disposed at a longitudinal center location of the boom so as to be swingable about a third horizontal pivot as a fulcrum. A base-end link member extends between a fixed bracket and the inner free-end part and a free-end link member links the outer free-end part to the implement.
