Liquid Ballast - New Holland T7030 Operator's Manual

LIQUID BALLAST

Filling the front and rear tyres with liquid ballast is a
convenient method of adding weight. A solution of
calcium chloride and water is recommended. This
gives a low freezing point and provides a higher
density than plain water.
IMPORTANT: In some countries it is illegal to use
calcium chloride as a ballast solution for tyres.
Ensure that you comply with the legal requirements
of your country. Use cast iron weights as an
alternative to liquid ballast.
NOTE: When filling
chloride/water solution the valve should be at the
highest point on the wheel. The valve should be at
the lowest point when checking or adjusting air
pressure if the tyre contains liquid ballast. Special
equipment is required to water ballast tyres. See
your authorised dealer or tyre supplier for details.
The following tables show the quantity of calcium
chloride and water required for each tyre size option
and is based on 0.6 kg of calcium chloride per litre of
water. The figures in the table will give a 75% fill of
the tyre. This calcium chloride/water solution will give
protection from freezing down to an ambient
°
temperature of --50 C (--58
WARNING
When mixing the ballast solution it is imperative the
calcium chloride flakes are added to the water and
the solution stirred until the calcium chloride is
dissolved.
Never add water to calcium chloride as considerable
heat is generated. If the flakes should contact the
eyes, wash the eyes immediately with clean, cold
water for at least 5 minutes. Consult a doctor as soon
as possible.
NOTE: Liquid ballasting of front tyres on a 2WD
installation is not recommended.
