4.2
Checking Tire Pressures and Adding Tire Ballast
Checking the tire pressure and possibly adding tire ballast will help ensure the proper operation of the windrower.
4.2.1
Checking Tire Pressure
The tires must be at the correct operating pressure. Check the pressure of the windrower tires using a tire pressure gauge.
To inspect a tire
’
s air pressure level:
1.
Determine the type and size of tire installed on the windrower.
2.
Refer to the following table to determine the appropriate air pressure:

3.
Adjust the tire pressure as needed.
NOTE:
Check the maximum inflation rating on the tire
’
s sidewall. Do
NOT
inflate the tire beyond the maximum pressure
specification.
4.2.2
Adding Tire Ballast
When using a large header on a windrower, adding fluid ballast to the caster tires will improve machine stability. Machine
stability is also affected by different attachments, windrower options, terrains, and driving techniques.
The maximum fluid ballast capability per tire is 75% of full, or when the fluid is level with the valve stem at the 12 o
’
clock
position. Always add an equal amount of fluid on both sides. Fluid can be added to any level up to maximum fill. Consult
the following tables before adding fluid ballast to the tires:

Weights typical for calcium chloride and water mixtures. Reduce weight by 20% if only water is used (for areas that do
not freeze).
