operating trailed attachments, care should be taken
when turning to prevent the implement from fouling
the linkage.
4.16.1 - Linkage
The tractor is supplied with Category 3 ball joint linkage or
with optional category 3 fast linkage hitches.
4.16.2 - Lower links
• Fixed ball end type (Fig. 62)
• Hook and ball type (Fig. 63)
The hooks engage automatically in the ball joints which are
fitted to the hitch pins. The normal balls are used for clevis-
end linkage; the balls with guide cones are used for single
pin linkage. Ensure the linkage is properly locked.
The hooks can be unlocked for uncoupling from the cab,
using cables (accessory).
