トアーム下降回動速度制御機構の解除構造。 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 an 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 the up/down interlocking mechanism 19 is provided with a fluid type cushioning device P.
A downward rotational speed control mechanism for a lift arm, which acts as a buffer for the vertical movement interlocking mechanism 19 only from a predetermined lowering position of the lift arm 8 at which the lift arm 8 rotates downward, thereby suppressing the downward rotational speed of the lift arm 8. , the fluid-type cushioning device P is connected to the lifting and lowering interlocking mechanism 1.
9. A release structure for a lift arm lowering rotation speed control mechanism in a tractor that can be freely engaged and detached from 9.
