度制御機構。 An elevating interlocking mechanism 19 is interposed between the lift arm 8 that protrudes from the hydraulic case 7 at the rear of the tractor A so as to be movable up and down, and the arm elevating operation lever for operating the lift arm. 19, the lift arm 8 is configured to move up and down in conjunction with the operation of the arm up/down operation lever, and in the up/down interlocking mechanism 19, the up/down interlocking is performed only from a predetermined lowering position of the lift arm 8 rotating downward. A lift arm lowering rotation speed control mechanism for a tractor, which is provided with a buffer spring 28 that functions as a buffer in the mechanism 19 and suppresses the lowering rotation speed of the lift arm 8.
