What kind of oil goes in a bunton 48 walk behind mower?

Uses 2 types of oil, motor and hydraulic. For motor oil, the plate below the fill spout says SAE 30 if temperature is above 32 degrees F and I forgot what it says if the temperature is less than that.

For hydraulic oil, the type is shown on the top of the mower near the handles, again next to the fill spout. It shows 20 W 50 as the type needed. There's generally no need to change hydraulic oil unless you are having problems with it.

Keep in mind that your oil types will be determined by type of motor and other factors, so your oil type may be different.
