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.

5.7.11 Maintenance Schedule
The Maintenance Schedule specifies the periodic maintenance procedures and service intervals.
Regular maintenance is the best insurance against early wear and untimely breakdowns. Following this schedule
will increase machine life.
For detailed instructions, refer to the various procedures in this chapter. Use the fluids and lubricants specified in
5.3.1 Recommended Fuel, Fluids, and Lubricants, page 262 .
Service Intervals: The recommended service intervals are in hours of operation. Where a service interval is given
in more than one time frame, for example, 100 hours or annually, service the machine at whichever interval is
reached first.
IMPORTANT:
Recommended intervals are for average conditions. Service the machine more often if operated
under adverse conditions (severe dust, extra heavy loads, etc.).
