To avoid personal injury or death:
• Before jacking up the tractor, park it on a firm and level
ground and chock the front wheels.
• Fix the front axle to keep it from swinging.
• Select a jack that withstands the machine weight and set it
up as shown below.

[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.
• 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.
