then stow the top link in its clip.
6. Detach the lower links and stow the
linchpins in the links in the stowage
points provided.
7. Disconnect the PTO shield and shaft.
8. Disconnect hydraulic hoses and cap
the ends. Replace the dust caps on the
control valve couplings.
9. Start the engine and drive the tractor
forward before returning the Position
Control to the ‘Transport’ position.
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 system, unnecessary dis-
charge must be avoided, as damage to the
relief valve may result in over heating the
system and a reduction in the maximum
hydraulic pressure.
MULTI-HOLE DRAWBAR AND STAYS
(Fig. 30)
(Optional accessory)
The drawbar fits Category 2 link ends
and is only to be used for light applica-
tions. The lateral adjustment of 432 mm
(17 in) is provided by nine holes in the
drawbar, and the stays give a height range
of between 279 mm (11 in) and 635 mm
(25 in) above the ground.
WARNING
The drawbar height must be correctly
set for the implement being towed. The
drawbar must not be set above the centre
line of the rear axle. Failure to carry out
these instructions can result in the trac-
tor overturning.
• DO NOT use the drawbar without stay
links. Attaching the drawbar:
1. Place the drawbar on the ground and
attach the stay links to the drawbar
ends (1).
2. Lift the drawbar components and at-
tach the assembly to the lower link ball
ends, secure with linchpins (2).
3. Secure the top ends of the stay links
to the centre housing with the long pin
and linchpin (3).
4. Adjust the drawbar height by lengthening
or shortening the stay links as required.
For normal working height, set at 470
mm (18 in), line up the notches in the
stays. Tighten the bolts securely (4).
5. The Position and Draft Controls must
always be in the lower position when
the drawbar and stays are in use.
