在に突設したリフトアーム８と、同リフトアーム
操作用のアーム昇降操作レバーとの間に昇降連動
機構１９を介設して、同昇降連動機構１９により
リフトレバー１４操作に呼応したリフトアーム８
の上下回動作動がなされるように構成すると共に
、昇降連動機構１９中には、クツシヨンワイヤ２
８を設けて、同クツシヨンワイヤ２８が下降回動
するリフトアーム８の所定下降位置からのみ同昇
降連動機構１９に緩衝機能して、同リフトアーム
８の下降回動速度を抑制するようにしてなるトラ
クタにおけるリフトアームの下降回動速度制御機
構。 An elevating interlocking mechanism 19 is interposed between a lift arm 8 projecting 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. The lift arm 8 responds to the operation of the lift lever 14 by
In addition, the lifting interlocking mechanism 19 includes a cushion wire 2.
8 is provided so that the cushion wire 28 acts as a buffer to the lifting interlocking mechanism 19 only from a predetermined lowering position of the lift arm 8 rotating downward, thereby suppressing the downward rotational speed of the lift arm 8. A mechanism for controlling the downward rotational speed of the lift arm in a tractor.
