E) Combination power harrow/seed drill D 7
1.
If the AMAZONE power harrow
is
used
in
conjunction with
an
AMAZONE
seed drill, then it
is
essential that the power harrow
is
coupled
as
closely
as
possible to the tractor
in
order to keep to a minimum the load on the front
axle of the tractor. This
is
done by adjusting horizontally the lower link
points
of
the power harrow
(Fig.
5/1
). It may be necessary to shorten the
universal joint shaft,
in
which case it must be ensured that the overlapping
of
the profile
is
sufficient (minimum 4 inches =
10
cm). The load on the
front axle
of
the tractor can be increased by attaching additional weights.
The lower links
(Fig.
5/2) of the tractor should have some freedom
of
lateral
movement.

To
couple the power harrow to the seed drill D
7,
bolt the connecting parts
to the rear of the power harrow
in
accordance with
Fig.
5.
Ensure that the
lower links
(Fig
. 5/3) are fastened outside the supporting beams
(Fig.
5/4
).
Connect the AMAZONE quick-action coupling, which
is
supplied
as
standard
equipment with the seed drill D 7 Super and which can be supplied
as
a
special accessory with the seed drills D 7 Standard and D 7 Junior, to the
three links
(Fig.
5/5)
of
the connecting parts
in
accordance with
Fig.
5
To
connect the power harrow to the seed drill, move back the to the tractor
mounted power harrow until the hitch pins of the quickaction coupling
(Fig.
6/1) are below the three-point link bolts
of
the seed drill. Now slowly
raise the power harrow by operating the tractor hydraulics until all three
hitch pins
of
the quick-action coupling grip the three link pins
of
the seed
drill. Finally, lock the quick-action coupling by inserting the marking pins
(Fig.
6/2) underneath the upper hitch pin into the two marking brackets
(Fig. 6/3). The seed drill can
be
coupled easily and quickly only if the quick-
action coupling
is
laying against the vertical supporting beams
(Fig.
6/4)
(lowermost position).
The seed drills D 7 Super, D 7 Standard and D 7 Junior with bolted lower
link points can be connected to the power harrow even without the
AMAZONE quick-action coupling
in
order to reduce the required hydraulic
lifting power of the tractor (smaller centroidal distance). The AMAZONE
quick-action coupling
is
always necessary for the combination power
harrow/seed drill D 7 with welded lower link point.
