摘要

A pivot assembly for the inwardly swingable outrigger beam of a rotary-rake haymaking implement having a pair of hollow beam sections relatively swingable to include an angle of 90 DEG between them in one position thereof and axially aligned in another position thereof, a shaft extending through the beam sections and axially subdivided into a pair of interconnectable shaft sections disengaged from one another in said one position and mutually interconnected in said other position of the beam sections, and a ball joint interconnecting said beam sections for relative pivotal movement thereof between these positions about a vertical axis, laterally offset from the shaft in said other position and perpendicular to the axis thereof, and a horizontal axis generally parallel to one of the shaft sections, the axes intersecting one another.
