I'm getting tired of paying John Deere's prices for their Low Viscosity Hy-Gard (aka Hy-Tran) fluid, otherwise known as "J20D".

Any one know of a substitute for this, from someone like Shell or Mystik?

What other suppliers do you use.
Any of the major oil companies ( Shell, Exxon, etc) will have generic hydraulic/transmission fluids.

Big R's, Farm fleet, rural king, most NAPA's in Central Il all carry a low priced universal tractor fluid that meets the jd specs.

Just to clarify...

All of these manufacturers/stores have the equivalent of *low-viscosity* Hy-Gard?

I'm not referring to the regular stuff...

If they all carry the equivalent of los-vis Hy-Gard, then what rock have I been under???

I misread. They very well may not have a low vis equiv.
I would think the local jobber would carry an equiv.

Citgo has Lo-Temp Trans Gard that meets the J20D spec.. Not sure if there is a Mystic(Citgo) equivalent.

Amsoil and Chevron have single products that meet BOTH the C and D rating. Top notch products, but initial cost probably won't be less.

Texas Refinery Corp's Special Low Temp Universal Torque Fluid meets the JD J20D spec. It has a -50 deg pour point so low temp operation shouldn't be a problem.

Chevron "Synthetic All-Weather THF" meets JD J20C and J20D specs. Viscosity at 40*C/100*C is 44.7/9.5 cSt.

Chevron "THF W" meets J20D only. Viscosity at 40*C/100*C is 34.4/7.3 cSt.

How much are they charging for it mrsilv04? Reason I ask is a guy at the TractorByNet forum said he paid some amazing amount, like $10/qt or something, and I just got some from my local J-D guy on Saturday for $12/gal for my X595. It's definitely J20D "Low-Vis/HyGard".

I am using Amsoil Synthetic Tractor Hydraulic/Transmission Oil
SAE 5W-30 (ATH) in my JD lawn tractor. It meets the specs for the J20D fluid.

According to the Official John Deere service manual for Lawn Tractors LX255,LX266,LX277,LX2 (TM1754), You Can use a SAE 5W or 10W30 Oil (Synthetic or Mineral) or John Deere HY-GARDô J20C Oil. Its your choice. I had some HY-GARDô on the shelf in the garage that meets the J20D spec, but if I run out, its nice to know that I can use an SAE motor oil. I'd put a copy of the PDF on here if it was legal, but unfortunately I had to pay money to John Deere for it and I don't want to be sued for copyright stuff.

What's the application here?

For what it's worth, Deere does specify engine oil to be used as hydraulic fluid in quite a few applications- including machines that are far more expensive and powerful than lawn tractors. They'll often have a chart in the operator's manual showing a variety of engine oil viscosities and either standard or low-vis hyguard, depending on temperature range.

Case also uses engine oil in some of their skidsteer hydraulic systems. But they have an additional additive to put in with the 10w30.
