Hydraulic fluid type for a Deere 690C, any help is appreciated! Thanks!

Hello Everyone,

I'm buying a really nice low hours 690C for working around my property, don't expect I'll be racking up a ton of hours on it.

I'm planning to change all the filters/fluids to be on the safe side and start fresh with it. I've been reading some conflicting posts on the best route to go with the hydraulic fluid. I was going to take a sample and have it analyzed, but at the end of the day, I guess I can't be sure exactly what type of fluid is in it now.

First question-...
