Coupling hook

Fig. D-38a. Coupling hook

The  coupling  hook  (hydroficated)  is  in-
tended  for  working  with  semi-trailers  and
agricultural machines based on them. It is
mounted  on  the  tractor  with  the  lift-type
guides of the traction-hitch mechanism. It
can be delivered complete with the towing
jaw intended for working with trailers and
trailed agricultural machines.
