Is the specifications data available for the OEM equipment? I would need the GPM rate and operating PSI. And as a bonus, the diagram or schematic for the hydraulic system ports and description. Thanks, Darrel

I'll get that if I remember.

Plus proof that PS was not considered an option

The tractor is at my moms place, and that's where I keep the literature too.

Heading over there pretty soon

Thanks Mark,

Just to let the other readers know that Rock sent some information @ my e-mail for the steering on the JD 850 I was inquiring about. It only took my internet provider 6.5 hrs. to download. But that was better than I thought.
