Hi Bootlegger,

The Transaxle takes 30W Engine Oil.

I have a 1993 (Toro Model Number 73501) in the 3XXXXXXX SN range. I'm to WH 520s myself and compared the numbers you listed with what I have and they are not similar. Here's a link to the Toro site which may help you determine its year of MFG https://homeownersolutions.toro.com/portal/...ductDetailsPage

Good luck with your 520!

:thumbs: Glad to have you aboard.

Check that model number again and see if it isn't 31-20OE01 (that's an O for Onan)

That would make it a 520-H Garden Tractor, 1988

Uses 10W30 or 10W40 motor oil in the hydro.

Bootlegger, it is a 1988. Here is the Toro site that will lead you to the manuals, etc, for your model number:

Please note that in the model number, 31-20Oe01, the 20 is for hp and the 5th letter is an O for Onan. On the Toro site, the 5th letter has to be input as an O for Onan.
