Liquid ballast
Tires are filled with liquid ballast only when traction of wheels with soil is not sufficient
under unfavorable conditions (over humid soil, etc.).
NOTE: It is not recommended to ballast front tires, as this makes tractor steering
worse.
In winter it is recommended to use the mixture of calcium chloride with water at:
Ambient temperature, °С, up to Amount of calcium chloride, g/l of water
to -15°С
to -25°С
to -35°С
200
300
435
This ensures low freezing temperature, increase of solution density and gives safe and
economical ballast. If use it correct, it don’t result in damage of tires, tire tubes or wheel
rims.
When filling tires with liquid, the tire valve should be in the wheel crown.
In table below there are solution volumes being filled the rear tires:
Tires dimension Volume of liquid being filled, l/tire
15,5R38 250
IMPORTANT! Radial tires should be filled with the liquid ballast to the volume no more
than 40…50%. When filling more, air volume will be insufficient to absorb the shocks that
may result in tire damage. This is due to the lower air pressure, provided for radial tires.
Diagonal tires can be filled up to 70% of volume.
WARNING: When making solution, flakes of calcium chloride should be added to
water and solution mixed until calcium chloride CaCl2 fully dissolves. Never add
water to calcium chloride. Put on goggles when making solution. When solution
hits eyes promptly wash them with pure water for five minutes and immediately
address the doctor.
