hole (5 Fig. 20). This latter position reduc-
es the operating arc of the lower link end.
NOTE
The lift rod bolts must always be ad-
justed so that they can rotate. The bolts
must also be through the corresponding
holes in both lower link arms.
Lower links (4 Fig. 20)
When fitting implements to the lower
links always fit the left-hand link first and
use the levelling lever, as necessary, to
assist in the fitting of the right-hand link.
The maximum recommended lift load for
normal working is:
1415 kg (3120 lbs) for the 470 tractor.
The check chains (2) ensure that the
lower links DO NOT sway into the rear

3. Fit the new ball by locating it with the
narrow section in line with the slot,
then refit the spring clip as shown in
(Fig. 22). Adjust the length of the check
chains.

The check chains prevent the lower
