Adding Tire Ballast - MacDon D1 Series Unloading And Assembly Instructions

4.3 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.

When the 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.
