I've never heard of this machine and just googled a couple pics, I'll give you what I know. Most all Hydro-gear pumps run 20w50 engine oil, Older Eaton pumps ran 30w engine oil. If the oil in the tank looks like engine oil run which ever oil above for the pump maker.....
I would also think most any of the medium weight hydraulic fluids would work. Something like an AW47 hydraulic oil. You might want to talk to a hydraulic rebuild shop and get some other suggestions.
If you don't know what type is in there. Take a sample and send it to Blackstone labs and have them test it then go from there. Posted via Mobile Device
Can you tell me if the hydro motors on the mower deck can be rebuilt. I have one that is leaking a little. May just need a seal replaced .
