4.7
Adding Tire Ballast
When using large headers on the windrower, adding fluid ballast to the rear caster tires will improve machine stability.
Machine stability is also affected by different attachments, windrower options, terrains, and driving techniques.
Ballast capability per tire is at a maximum fill of 75% or when the fluid is level with the valve stem when the stem is
positioned 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.

1.
Weights given are for typical calcium chloride and water mixtures. Weight is reduced by 20% if only water is
used (for areas that do not require antifreeze protection).
2.
If only water is used, increase volume of water by 20% (up to maximum allowable fill per tire) to compensate.
