PERFORMING PREDELIVERY CHECKS
7.3 Tire Pressures and Ballast Requirements
7.3.1 Checking Tire Pressures
Measure tire pressure with a gauge:
• Bar: 32 psi (221 kPa)
• Turf: 20 psi (138 kPa)
• Caster: 10 psi (69 kPa)
7.3.2 Checking Tire Ballast
Fluid ballasting of rear caster tires is recommended to provide adequate machine stability when using large headers
on the windrower.
Also, the stability of machine varies with different attachments, windrower options, terrain and 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 the “12 o’clock” position.
Fluid can be added to any level up to maximum fill and always add an equal amount of fluid on both sides.
