[3] TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey ground.
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.
IMPORTANTQ
• Do not fill the front tires with liquid.
Injection
CAUTION
• When a calcium chloride solution is used, cool it before
pouring it into the tire.
• Do not fill tires with water or solution more than 75 % of full
capacity (to the valve stem level).
The following four ways can be used to inject water or a calcium
chloride solution into tires.
1. Gravity injection (Fig. 1)
2. Pump injection (Fig. 2)
3. Pressure tank injection (Fig. 3)
4. Injection directly from tap (only when water is being used).
NOTEQ
• Once injection is completed, reset the air valve, and pump
air into the tire to the specified pressure.
