Using Liquid Ballast
RW71542-UN-05SEP00
A - Valve
Fill tube-type or tubeless tires up to valve level (40 percent full) with valve (A) in 4 o'clock position. Radial and bias tires hold same amount of liquid. When putting liquid in rear tires, make sure all tires on axle have same amount of liquid fill.

CAUTION: Avoid possible injury. Installing liquid ballast requires
special equipment and training. See your John Deere™ Dealer
or a tire service store.
IMPORTANT: Liquid ballast is not preferred. Liquid weight greatly increases tire stiffness at lower operating pressures, and greatly reduces ride performance.
Use calcium chloride to prevent water from freezing. A mixture of 3.5 lb. of calcium chloride per gallon (0.42 kg per liter) will not freeze solid above -50°F (-45°C).
IMPORTANT: A maximum liquid fill of 40 percent is recommended for better tractor performance.
NOTE: Use of alcohol as liquid ballast is not recommended.
In areas where freezing is not a problem and water is used as ballast, multiply weight shown in table by 0.8.
