Stabilizer adjustment:
Raise the implement into the transport
position.
Before working with soil engaging im-
plements, the stabilizers must be adjusted
to allow a total implement side-swing of
100 mm (4 in) measured at the implement
cross-shaft ends, i.e. 50 mm (2 in) of
movement either side of the tractor centre
line.
ATTACHING AN IMPLEMENT
WARNING
If two people are involved in attaching
an implement, great care must be taken.
When making any adjustment to the hy-
draulic lift system, the person in the area
of the linkage must stand clear.
1. Place the Draft Control Lever in the
fully raised position.
2. Lower the links using Position Control,
back the tractor up to the implement,
raise the lower links so that the left-
hand link is in line with the pin on the
implement.
3. Apply the parking brake before dis-
mounting from the tractor.
4. Fit the left-hand lower link first and
secure with a linchpin. If any small up
and down adjustments of the lower
links are necessary they must be made
from the driver’s seat.
5. Attach the right-hand lower link to the
implement. Use the levelling lever if
necessary to adjust the height of the
link, then fit the linchpin.
6. Attach the top link to one of the three
hitch points on the control beam if fit-
ted (Fig. 28).
Fig. 28:
Using a high hitch point increases
the sensitivity of the hydraulic system. It
also reduces the ground clearance during
transport and the degree of control, which
can cause uneven depth control.
Using a lower than normal hitch point
causes the opposite effects to the above.
7. The top hole ‘A’ (Fig. 29) is used for
light draft implements and for maxi-
mum depth control in shallow work i.e.
