Removing Equipment
Rest the implement on the ground and make sure that it
is stable. Remove the safety screws (3) fig. 4 from the
two hooks to free the catches (1) fig. 4. While sitting in
the driving seat, pull the control cable (1) to unhook the
third point (3) fig. 5. Slightly raise the implement, then
release the hook ends by pulling the control cables (2) fig.
5 directly from the driving position. Lower the lower arms
until the hooks are released.
Tapered profiles
Three second category ball-bushings are supplied for in-
stallation on the implement, if required. The ball-bushing
with projecting lips (1) should be installed on the imple-
ment upper hitch pin. The two plain ball-bushings (3) with
their detachable guides (2) should be installed on the im-
plement lower hitch pins.
The three-point linkage system enables connecting sec-
ond category implements.
It is recommended to respect the dimensions (C) and (D)
given in the table below in order not to damage the cou-
pler.
