Anybody have any recommendations on which brand/weight hydro oil to run in the open sided Fords?  I was going to use a bottle of Deere Hydrostatic Fluid I have laying around, but figured I'd ask first.  The manual I printed off wasn't much help.  Thanks

If its for the big tractors , it will be just fine. Don't use any atf fluids , they are not thick enough or have the best lube packages for the pressures obtained by these units.

JD 20D low viscosity is what JD recommends for the Sundstrand hydros in the 300 series tractors. It should be compatible with any small tractor hydro drive. They also make a higher viscosity version for hotter climates.

 According to the specs I saw for the JD 20 oil it is too thin for the Eaton Hydro . They like a heavier oil . The standard Hy-Guard is better . You want a 32wt hydraulic/trans fluid. But even straight hydraulic fluid that is 32wt will work just fine. Oh and believe me straight hydraulic oil will lube the transmission gears just fine especially ones inside an aluminum gear case.   

  The differences between the 2 are moisture and anti-foaming additives . They both have corrosion resistance , but the trans stuff has anti-foaming additives for high speed transmissions like on the big tractors as they run down the road.
