Adding Tire Ballast - MacDon D65 Assembly Instruction Manual

3.11 Adding Tire Ballast

When using large headers on windrower, adding fluid ballast to 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 fluid is level with valve stem when stem is positioned
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.

When recommended fluid ballast has been added, proceed to
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.
