Wide Angle Joint and Double Joint are also known as the Cardan Joint due to regional differences or other language habits reasons.

Cardan joints are custom-designed components for tractor power take-off (PTO) shafts, providing enhanced angular flexibility. These joints are specifically engineered to handle the varying angles that can occur between the tractor’s PTO shaft and the implement’s input shaft. When the tractor and implement are not in perfect alignment, such as during work on uneven ground or when using implements with adjustable angles, the PTO shaft must be able to adjust and accommodate these changes. This is where Cardan joints are essential, offering the necessary flexibility to handle such conditions.
