What color is case Hytran ultra?

Rudiger28 · 2026-08-01 17:28

I just changed the hydraulic filter on my Case 521F, the fluid coming out was green- is this normal? Specs call for Hytran Ultra. I’m not the first owner but I’m pretty sure it’s the first filter change @ 2500 hrs.

    Green is food,water or environment safe bio oil.

    Hytran is like amber color with a slight reddish tint to it. Not sure if Ultra is the same thing or something different.

    Case oil analyst kit & check the fluids. Have a good one
