New Member. I use JD Hy-gard in my 4255 but 303 spec oil is fine for your 3020. I’d suggest to also change hyd filter & check/clean sump screen.
What kind of hydraulic fluid does a John Deere take?
In the lab and in the field, Hy-Gard is preferred by John Deere engineers to deliver increased performance and protection of transmission and hydraulic systems. Hy-Gard retains proper viscosity over a wide range of operating temperatures thanks to its polymeric viscosity improver.
How much hydraulic oil does a 3020 John Deere hold?
John Deere 3020 Transmission

What hydraulic oil should I use in my tractor?
You should always use a trans-hydraulic fluid that says on the label that it meets the specifications of your tractor’s maker. There are also universal trans-hydraulic fluids that meet the specifications of most tractor manufacturers. For more maintenance tips, visit Blain’s Farm & Fleet’s Automotive blog.
What weight oil is JD Hy-Gard?
Hy-Gard oil can be used in most applications calling for 10W-30 or 5W-30 engine oil for transmission and hydraulic oils.
What happens if you use the wrong hydraulic fluid?
If operating viscosity is lower than ideal, more power is lost to friction and internal leakage. Using the wrong viscosity oil not only results in lubrication damage and premature failure of major components, it also increases power consumption (diesel or electricity) – two things you don’t want.
How much hydraulic fluid does a 4020 hold?
Oil capacity on most 4020 diesels increased from 8 to 12 quarts starting with the 1969 model year, tractor serial number 201,000. High-crop diesel tractors retained the 8-quart capacity throughout the production run.
Is tractor fluid the same as hydraulic fluid?
They are designed for applications in different tractor and heavy-duty machinery components. Hydraulic oil transfers power, while tractor fluid lubricates the moving parts within a transmission. Choosing the right tractor fluid and hydraulic oil can have an effect on the performance of your equipment.
How do I check my John Deere hydraulic oil?
John Deere Hydraulic System Diagram
- Park the tractor on level ground with implements down.
- Run the engine at approximately 1000 rpm for at least one minute. Stop the engine and wait three minutes for the oil to settle. …
- View the oil level in sight glass (A). …
- If oil level is below the lower mark, you will need to add oil.
Where do you put the hydraulic fluid in a John Deere tractor?
Get an Accurate Reading
- Remove the cap from the reservoir, which is usually located behind the driver’s seat on John Deere tractors. …
- Pull out the dipstick and read the level. …
- If you do need to add fluid, use a clean funnel to pour the oil into the reservoir slowly.
What weight is tractor hydraulic fluid?
Universal Tractor Hydraulic Fluid is a SAE viscosity grade 10W-30 and meets API GL-4 gear oil specifications.
What the difference between 32 and 46 hydraulic oil?
The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker. So, for example, a hydraulic system operating in a cold climate like Tasmania would run better with a lower viscosity grade of 32. … Here in Perth, 46 and 68 are better suited to our climate.
