   Quick coupler

   A - Retaining Bolts

   B - Cap Screws

   C - Side frame, right

   D - Side frame, left

   E - C-clip and pin

   F - Cap screw

   For some series/tread widths, a changeover from Category 3 to Category 3N is necessary.

   The quick coupler can be adjusted to Category 3 or 3N implements. Use Category 3 whenever possible, especially for heavy loads.

   IMPORTANT: When the quick coupler is converted from Category 3 to Category 3N, different wear plates and shims have to be installed, depending on the tractor model. See "Adjust Telescopic Draft Links for Category 3 or 3N" in this section.

   IMPORTANT: To prevent damage to the device, the spreading dimension of the telescopic draft link has to be adjusted to the quick coupler. See "Draft Links — Adjust Spreading Dimension" in this section.

   NOTE: When the "DeLuxe" quick coupler is used in Category 3N, the spreading dimension has to be set to 900 mm.

   NOTE: The conversion from Category 3 to Category 3N is described below.
