Water Balasting - MASSEY FERGUSON 410 Operators Instruction Book

Maintenance and Adjustment
Water ballasting
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. If the flakes should
contact the eyes, wash the eyes immediately with
clean, COLD water for at least five minutes. See
a doctor as soon as possible.
Filling the front and rear tires with liquid ballast (Fig.
133) is a convenient method of adding weight to
secure more traction and reduce slippage and tread
wear. Either cast wheel weights can be added or the
tires can be filled with a water/antifreeze solution of
50% to 75% of the tire volume, this will ensure similar
flexibility to air inflated tires. Where freezing
temperatures never occur, plain water can be used,
but the weight added will be less. Where antifreeze
protection is needed and in view of the trend towards
greater environmental awareness, the use of calcium
chloride is being phased out and alternative antifreeze
additives used. Charts (see Specification section)
are provided in the specification section giving the
weights and capacity for water and calcium chloride.
All recommendations for tube tires are directly
applicable to tubeless. In the case of tubeless tires
it is recommended that an antifreeze solution is used
in place of calcium chloride to prevent corrosion of
the rim. The antifreeze solution should be a mono
ethylene glycol based fluid (radiator antifreeze). Frost
protection (Table 10) using Massey Ferguson
antifreeze as follows:

Table 10
Mixing the solution of calcium chloride
Prepare the calcium chloride mixture in a suitable
container by pouring the calcium chloride into the
water (never the water into the calcium chloride, as
considerable heat is generated in this mixing process).
The mixture should be allowed to cool to atmospheric
temperature before pumping into the tire. The pump
can also be used to mix and cool this solution by
circulating it through the pump and back into the
barrel.

Filling
1. Jack up the tractor.
2. Turn the wheel to bring the valve to the top position.
3. Remove the valve core housing and make the
connection with the pump using a special filling
adaptor.
4. Pump into the tire the correct quantity of solution
as detailed .
5. Set the final working pressure with the tire mounted
on the tractor, with the weight on the tire, and the
valve at the bottom using an air/water gauge.
Removing
1. Jack up the tractor.
2. Turn the wheel to bring the valve to the bottom
position.
3. Remove the valve core housing and make the
connection with the pump using a special filling
adaptor.
4. Completely evacuate the tire.
5. Re-inflate the tire to the recommended pressure.
6. The valve should be at the lowest point when
checking or adjusting air pressure if the tire is liquid
ballasted.
