Tractor operation

b) Remove the dowel pins (1) of both sta-
bilizers.
c) Press the implement sideways so as
to achieve the implement alignment
(centralization). If necessary, rotate
the spindle (2) to make the installation
holes coincide with the pin (1).
Note
If you want to allow a implement
side-swing during the job, install the
dowel pins (1) into the second hole (3),
as shown on figure 23.
Pressure relief valve
Avoid using the tractor hydraulic sys-
tem in any way which may cause the pres-
sure relief valve (which is internal), to
discharge continually. This can be caused
by attempting to raise a load at the lower
links, greater than that which the system
is capable of lifting.
Although the relief valve will prevent
damage to other parts of the hydraulic sys-
tem, unnecessary discharge must be avoid-
ed as damage to the relief valve may result
in over-heating the system and a reduction
in the maximum hydraulic pressure.

Five types of lower link ends (Fig. 24)
can be fitted to tractors.
1. Interchangeable ball ends.
2. Fixed ball ends.
3. Wrist action ball ends.
4. Hook type ball ends.
5. Telescopic ball ends.
In this tractor, lower links have fixed
ball ends (2, Fig. 24).
Attaching an implement
Warning
If two people are involved in attaching
an implement, great care must be taken.
When making any adjustment to the
hydraulic 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 they are in
line with the pins on the implement. If
necessary, adjust lift rods (2 Fig. 17).
3. Apply the parking brake before dis-
mounting from the tractor.
4. Fit the left hand lower link first and
secure with a linch pin.
