PERFORMING PREDELIVERY CHECKS
5.3 Checking Tire Pressures and Adding Tire Ballast
5.3.1 Checking Tire Pressures
Check tire pressures with a gauge.
• Bar: 221 kPa (32 psi).
• Turf: 13 8 kPa (20 psi).
• Caster: 69 kPa (10 psi).
5.3.2 Adding Tire Ballast
When using
large headers on windrower, adding fluid ballast to rear cas ter tires will improve machine stability.
Machine st
ability is also affected b y different atta ch ments, windrower options, terrains, and driving techniques.
Ballast ca
pability per tire is at a maximu m fill of 75% or when fluid is level with valve stem when stem is positioned
at 12 o’cl
ock position.
Always ad
d an equal amount of fluid on both sides. Fluid can be added to any level up to maximum fill.

used (for areas that do not require antifreeze protection).
