Ballast Requirements
Fluid ballasting of rear caster tires is recommended to provide adequate machine stability when using large
headers on the windrower. Also, the stability of the machine varies with different attachments, windrower options,
terrain, and the operator's driving technique.
Ballast capability per tire is at a maximum fill of 75%, or when fluid is level with valve stem when the stem is positioned
at 12 o'clock. Fluid can be added to any level up to maximum fill. Always add an equal amount of fluid on both sides.
