[5] TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey grounds.
Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be
used in winter since it freezes at 0 °C (32 °F). The calcium chloride solution will not freeze and moreover, affords
higher effect than water since its specific gravity is higher than that of water by about 20 %. Below is an explanation
of calcium chloride solution injection.
• Do not fill the front tires with liquid.
Preparation of Calcium Chloride Solution
• When making a calcium chloride solution, do not pour water
over calcium chloride since this results in chemical reaction
which will cause high temperature. Instead add a small
amount of calcium chloride to the water at a time until the
desired solution is achieved.
