38. Front Wafer Weights
1. Retaining bolts
A tow hook is built into the mounting bracket. However,
if this facility is required when the front end weights are
installed then the centre weight of the five must be
replaced by a special weight with a built in tow-hook.
This special weight is 30 lb (13 kg) heavier than the
standard weight and has the effect of increasing the
overall weight of the set to 360 lb (163 kg).
NOTE :
When the central tow-hook weight is installed
then the retaining bolts must also be installed.
Liquid Ballast
Filling the front and rear tires 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.
The table shows the quantity of calcium chloride and
water required for each tire size option and is based on
0.6 kg. of calcium chloride per litre of water to give a
75% fill of the tire. This calcium chloride/water solution
will give protection from freezing point down to an
ambient temperature of –46
0
C (–51
0
F).
CAUTION :
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.
NOTE : When filling tires with a calcium chloride water
solution the valve should be at the highest point on the
wheel. If the tire contains liquid ballast, the valve should
be at the lowest point when checking or adjusting air
pressure. Special equipment is required to water ballast
tires. See your Tractor Dealer or Tire Supplier for details.
Front tractor tubes do not have air/water valves fitted
as standard equipment, A suitable air/water valve must
be fitted to enable front tires to be filled with calcium
chloride solution.
TIRE INFLATION
Upon receiving your tractor, check the air pressure in
the tires and recheck every 50 hours or weekly.
When checking tire pressure, inspect the tires for
damaged tread and side walls. Neglected damage will
lead to early tire failure.
Inflation pressure affects the amount of weight that a
tire may carry. Locate the tire size for your tractor in the
Tire Pressure and Load Tables in Section C of this
Manual. Do not exceed the load for the pressure listed.
Do not over or under inflate the tires.
WARNING :
Installing or servicing tires can
be dangerous. Whenever possible, trained
personnel should be called in to service or install tires.
In any event, to avoid the possibility of serious or fatal
injury take the following precautions:
l Never attempt tire repairs on a public road or
highway.
l Do not inflate a steering tire (front tire) above the
manufacturer’s maximum pressure shown on the
tire or beyond the maximum pressure shown in
Section-C if the tire is not marked with the
maximum pressure rating.
l Never inflate any traction tire (rear tire) over 35 lbf/
in
2 (2.4 bar). If the bead does not seat on the rim
by the time this pressure is reached, deflate the
tire, relubricate the bead with a soap/water solution
and reinflate. Do not use oil or grease. Inflate
beyond 35 lbf/in
2
with unseated beads may break
the bead or rim with explosive force sufficient to
