Rear Ballast - Kubota B3300SU Operator's Manual

36 TIRES, WHEELS AND BALLAST
BRear Ballast
Add weight to rear wheels if needed to improve traction or
for stability. The amount of rear ballast should be matched
to job and the ballast should be removed when it is not
needed.
The weight should be added to the tractor in the form of
liquid ballast.
C Liquid Ballast in Rear Tires
Water and calcium chloride solution provides safe
economical ballast. Used properly, it will not damage tires,
tubes or rims. The addition of calcium chloride is
recommended to prevent the water from freezing. Use of
this method of weighting the wheels has the full approval
of the tire companies. See your tire dealer for this service.
