Adding Tire Ballast
When using a large header on a windrower, adding fluid ballast to caster tires will improve machine stability. Machine
stability is also affected by different attachments, windrower options, terrains, and driving techniques.
Maximum fluid ballast capability per tire is 75% of full, or when fluid is level with the valve stem at 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.

3.
Weights typical for calcium chloride and water mixtures. Reduce weight by 20% if only water is used (for areas that do
not freeze).
4.
If only water is used, increase volume of water by 20% (up to maximum allowable fill per tire) to compensate.
