What type of hydraulic oil is used in a Ferguson TO-35?

The Ferguson TO-35 typically uses a multi-purpose hydraulic oil, specifically a type that meets the specifications of ISO 32 or 46. It's important to choose an oil that provides good lubrication and protects against rust and oxidation. Many owners opt for fluids labeled as Universal Tractor Fluid (UTF) for compatibility with hydraulic and transmission systems. Always refer to the owner's manual for specific recommendations.
