Claims

[Scope of utility model registration request]

Depending on the operating angle of the lift arm, the hydraulic cylinder installed between the lift rod and the machine body automatically expands and contracts, increasing the operating angle range of the lower link and increasing the amount of lift of the work equipment. In the work equipment lift amount amplifying device for a tractor, an adjustment screw member is fixed to each of the pair of lift rods, and the screw members are screwed into screw holes formed at both ends of the connecting shaft member to create a lower link width adjustment mechanism. A cylindrical hydraulic cylinder connecting bracket having a flange portion in which a spiral connecting groove is formed is loosely fitted to one end side of the connecting shaft member, and a hydraulic cylinder connecting bracket is loosely fitted into the spiral connecting groove. A lower link configured to guide a connecting pin provided at one end and to allow the hydraulic cylinder connecting bracket to be tightened or loosened from the connecting shaft member using a lock nut screwed into the threaded member at one end of the connecting shaft member. Width and hydraulic cylinder mounting position adjustment device.
