The hydraulic fluid in our used 1996 Gravely 20G garden tractor is "black" color -- Would it be advisable to use: 1. "synthetic" Dextrom II or III fluid or "standard" Dextron II or III?

I would imagine that a garden tractor isn't going to get used in very much sub-freezing temperatures. For that reason I would run a standard or non-synthetic fluid.

THF is better for a trans/hydraulic/gear box common system if your tractor is only the hydrualic end then use a good AW 32 hydrualic oil. bruce
