FAQs
What kind of hydraulic fluid does a zero-turn mower use?
Most zero-turn mowers, including Ferris models, use either a high-quality 20W-50 motor oil or a premium hydraulic transmission fluid designed for hydrostatic systems. Always check the manufacturer’s manual for the exact recommendation.
What’s the difference between AW 46 and AW 32 hydraulic oil?
The main difference is viscosity. AW 32 hydraulic oil is thinner, making it better for colder climates and smoother operation in low temperatures. AW 46 is thicker, offering better protection and efficiency in warmer operating conditions.

Can I use SAE 30 for hydraulic oil?
SAE 30 is primarily an engine oil and not specifically formulated for hydraulic systems. While it may provide temporary lubrication, it does not contain the necessary additives for wear, foam, and oxidation control in hydraulic applications, so it is not recommended.
Can 20W-50 be used as hydraulic fluid?
Yes, 20W-50 motor oil is commonly recommended for many zero-turn mowers, including Ferris. It provides the right viscosity and protection for hydrostatic transmissions under high load and temperature conditions.
What happens if you use the wrong hydraulic oil?
Using the wrong hydraulic oil can lead to poor performance, overheating, increased wear on pumps and motors, and even system failure. It may also void manufacturer warranties.
