Liquid ballast in rear tires
The weight should be added to the tractor in the form of
liquid ballast.
Water and calcium chloride solution provides safe
economical ballast. Using the liquid ballast properly will
prevent tires, tubes, or rims from being damaged. The
addition of calcium chloride is recommended to prevent
the water from freezing. The addition of calcium
chloride for weighting the wheels has the full approval
of the tire companies. Consult your tire dealer for
addition of calcium chloride.
