Hydraulic fluid..I use for my JD 2020 Gas Tractor..John Deere

Resolved Question:

Which hydraulic fluid should I use for my JD 2020 Gas Tractor ? I found some that said it is substitute for John Deere 303. It seemed a little thicker than the JD Hy-Guard that I have used.

Hello Welcome to JA!

Rudolph Diesel :

I would stick with the – Hy-Gard hydraulic/transmission oil

Rudolph Diesel :

Is there a reasion you want to change to a diffrent fluid?

Rudolph Diesel :

– Hy-Gard oil has a viscosity between the ISO grades of 46 and 68 @ 40°C.

– Exceeds JDM J2OC specification. Some competitive oils may meet these minimum J20 specifications, but none meet the performance requirements placed on Hy-Gard oil

Rudolph Diesel :

The rest of your post on your question just showed on my end Yes i would run the -HY guard in the whole tractor

Rudolph Diesel :

– Hy-Gard hydraulic/transmission oil provides the best performance and wear protection for John Deere hydraulic and transmission systems.

– Recommended for equipment with either common system reservoirs or separate transmission and hydraulic systems, including those with wet brakes and wet clutches.

Rudolph Diesel :

Stick with the – Hy-Gard hydraulic/transmission oil You will save a lot of wear on parts

Rudolph Diesel :

Let me know if i can help you more! RD

The capacity of the system is 10 gallons. Should I drain the oil and replace it with hy-guard then?

Yes that will be the way to go
