Tightening Caster Wheel Anti-Shimmy Dampeners
Figure 5.226: Anti-Shimmy Dampener
Each caster is equipped with a fluid-filled anti-shimmy
dampener (A).
The mounting bolts (B) need to be checked periodically for
security. Refer to 5.12 Maintenance Schedule, page 415.
• Inboard bolt should be tightened to 135 Nm (100 lbf·ft)
• Outboard bolt should be tightened to 115 Nm (85 lbf·ft)
Ballast Requirements
Fluid ballasting of rear caster tires is recommended to provide adequate machine stability when using large
headers on the windrower. 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.

used (for areas that do not require anti-freeze protection).
