Also asked, what is Hy Gard oil?

Hy-Gard transmission and hydraulic oil is a unique oil developed by John Deere engineers to meet the exact needs of John Deere machines. Hy-Gard fluid is a multi-viscosity fluid with a high-viscosity index.

Additionally, what is j20d transmission oil? J20D Fluid. In contrast, J20D transmission oil offers a low-viscosity fluid at room temperature. As the outside temperature drops, the transmission oil's reaction is to immediately thicken, effectively clogging the transmission's gears.

Besides, what kind of hydraulic fluid does John Deere take?

Transmission and Hydraulic Oil Machine is filled with John Deere HY-GARD™ (J20C) Transmission/Hydraulic Oil at the factory. DO NOT mix oils. DO NOT use type “F” automatic transmission fluid or J20D Low Viscosity HY-GARD.

What type of oil does a John Deere tractor use?

10W-30

Can you use engine oil as hydraulic oil?

No you cannot use Motor Oil in a Hydraulic System. Motor Oil runs at a much higher temperature and Hydraulic Oil starts to fail at around 45c. Once you run Hydraulic Oil over this heat for a continued time the oil will start to 'burn'.

Can you mix different types of hydraulic fluid?

"Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?" Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.

Can I use 303 hydraulic fluid?

HYDRAULIC FLUID 303: A WARNING. According to the Petroleum Quality Institute of America, there are no specifications available for 303 Tractor Hydraulic Fluids and such products making “303” claims cannot be tested to assure compliance with any known specifications.

What happens if you put hydraulic oil in an engine?

Hydraulic oil is about the same as 1950's engine oil and would be OK to use in an emergency to get you home. If you used it for longer than a few days, you would start to form deposits in the engine that would clog oil ways and block your hydraulic valve lifters.

What is viscosity of hydraulic oil?


Viscosity, according to Webster's Dictionary, is the property of fluids and semi-fluids that defines its internal resistance to flow and shear. Or, in more simple terms, how thick or thin a fluid is. Also, as hydraulic fluid ages or experiences shear stress, oil molecules can break down and that lowers the viscosity.

Who makes JD oil?

Subject: RE: Who Makes JD Oil? Chevron formulates and packages John Deere Plus-50 and Northland makes the 0w-40 in the continental United States. In Europe it is made by Petro-Canada.

What weight is hydraulic fluid?

Viscosity is also most often expressed as the fluids ISO number or grade. Common ISO grades for use with hydraulic systems include 32, 46 and 68. Sometimes, 10, or 10 weight is mentioned as well.

What is ISO 68 oil equivalent?

SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100. As you can see, there is a bit of a difference between ISO 68 and SAE 30. The viscosity of the fluid largely determines the oil temperatures within which the hydraulic system can safely operate.

What oil do you put in a hydrostatic transmission?

You need SAE 10w30 that lists one of those classifications on the bottle. Any standard 10w30 motor oil should have it. Just check for it when you buy the oil. DO NOT use automatic transmission fluid (ATF) - that fluid is NOT compatible with the oil that's in there now, and it may even wreck your seals.

Do you need to change hydraulic fluid?


Oil analysis is the optimal approach to determining when to change your hydraulic fluid. Don't forget that hydraulic fluid degrades over time. If the machine has been running too hot, then the hydraulic fluid degrades even faster. In such cases, a hydraulic fluid change should be sufficient.

What color is John Deere hydraulic fluid?

Some is but HyGard is not. The initial JD factory fill has red dye added to it. However, JD HyGard is clear (oil color). If you want it to be red again after a transmission fluid change you have to add some dye back in.

How do you check the hydraulic fluid on a John Deere tractor?

Here's how you can check the hydraulic fluid on John Deere tractor: Step 1: Safely park the machine. Step 2: Open the engine cover, and remove the left side panel. Step 3: Remove the dipstick.

What color is John Deere Hygard?

John Deere Hygard Lo-Vis. Hydraulic fluid used to be colored RED to make it easier to see in the sight glass.

What is John Deere hydrostatic transmission?


Hydrostatic transmissions include mechanical parts such as a differential and a drive axle, plus rubber or metal hoses the liquid is pushed through. In the transmission section of your operator's manual, you'll find a section that covers oil viscosity. Here's an example from a John Deere manual.

What does j20c mean?

Fortunately, fluid that meet the current JDM J20C (high viscosity for summer) or JDM J20D (low viscosity for winter use) specification are backward-compatible to obsolete specifications, such as JDM 303, and can service the limited number of older tractors that are still in use in fields and farms across the country.

Can I use 5w30 instead of 10w30 in my lawn mower?

Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 (100074WEB) or 10W30 oil in all temperature ranges. Keep in mind that the use of synthetic oil does not prevent you from performing your regularly scheduled lawn mower maintenance (i.e. check oil, change oil, etc.).
