consult your ITMCo. Dealer.
5. Always drive slowly 20 Km/hr (12 mile/
hr) on the road if the tyre pressures
have been lowered for ploughing.
6. For maximum efficiency if ploughing
with crossply tyres, never use tyres
more than a third to half worn.
7. Tyre pressures and water ballasting de-
tails are quoted below in tables 4-6 to
4-8 for a few of the many tyre options
available for these tractors. These
figures are given as a guide only. For
specific details for your tractor if not
shown below, or if you wish to change
the tyre sizes, see your ITMCO. Dealer
who will have full tyre range specifica-
tions and recommended pressures sup-
plied by the tyre manufacturers.

Note
The tyre pressures given in tables
4-6 to 4-8 are the maximum for radial
tyres up to a road speed of 30 km/hr (20
mile/hr).
