![]() ![]() What weight is John Deere Hy-Gard hydraulic oil? Its viscosity is comparable to a SAE 20 crankcase fluid or an ISO 68 industrial oil for general purpose applications. It was made obsolete in 1974 when the use of whale oil, of which the specification was loosely based, was outlawed by the Endangered Species Act.Ħ24 ozAdditional informationWeight624 ozDimensions12 × 15.5 × 12 inSize5 Gallon Pail, 16 Gallon Pail, 55 Gallon Drum Hy-Gard viscosity places it between ISO 46 and 68 grades. Hy-Gard fluid is a multi-viscosity fluid with a high-viscosity index. Hy-Gard transmission and hydraulic oil is a unique oil developed by John Deere engineers to meet the exact needs of John Deere machines. As the outside temperature drops, the transmission oil’s reaction is to immediately thicken, effectively clogging the transmission’s gears. John Deere machine owners must place this type of oil within the transmission for the winter months. This oil is considered a winter grade lubrication fluid. Subject: RE: New to Deere oil, is HY-Gard a heavy weight oil ? I agree with Tim, HyGard is 15W-20W, Low Vis hy gard is 10W. What weight oil is John Deere low viscosity 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.Ĭan I use 20w50 in a hydrostatic transmission?įor use in hydrostatic transmissions in zero turn, stand on and riding mowers requiring a high viscosity transmission fluid, either 20W-50 or 15W-50. Petro-Canada Lubricants notes that the key difference between JDM J20A (which is replaced by the current JDM J20C or JDM 20D specification) is the addition of the Alli- son C-4 seal, oxidation, wear and frictional characteristics test requirements - a fact that is not commonly known. What is the difference between J20A and J20D? The J20D specification is the cold-temperature equivalent to J20C. Exceeds the minimum requirements of the JDM J20C specifications. John Deere Classic Hy-Gard oil can be used in most transmission and hydraulic applications calling for 10W-30 or 5W-30 engine oil. What oil is compatible with John Deere high guard? Hy-Gard may be used in many applications specifying either of these grades. Low-Viscosity Hy-Gard has an ISO 32 viscosity grade. No need to re-invent the wheel with this fluid choice.īoth Hy-Gard fluids are multi-viscosity fluids with high-viscosity index. HyGard/HyGard Low Vis is one of the best fluids on the planet for its intended use, and its competitively priced. Had a friend who was upset with the price of Deere’s Hy-Gard, so he went to Wal-Mart and bought whatever generic brand of hydraulic fluid they had. Trying to save a few bucks on Hy-Gard is the equivalent of “penny wise, pound foolish”. Here’s is a list- If you’re looking for an alternative to John Deere Hy-Gard, you may want to consider one of the following brands. John Deere Hy-Gard alternatives would work in all John Deere equipment, and it provides the same protection as the factory-filled Hydraulic and Transmission Oil. It flows well into the hydraulic system to greatly enhance the performance of your tractor.Īre there any John Deere Hy-Gard alternatives? Mobil Fluid 424 High Performance Tractor Hydraulic Fluid is an equivalent of the John Deere Hy-Gard oil specs JDM J20C. Same with the oil.What is the equivalent of John Deere Hy Gard oil?īelow is a list of other oils that are equivalent to the John Deere Hy Gard oil. In my tractors case, just because the filter will screw on the housing doesn't mean it's the same as the original in external construction and even the stuff inside we can't see. It was under warranty and GM said, tough luck buddy. It seems he didn't put an additive in it that was required by GM. They sold him some rear end oil, but then a1,000 miles later the rear end seized up. That's easy enough so he went to NAPA to get some rear end oil. I know of a situation where a DIY changed the rear axle oil in his GMC dually. But if a guy is very sure the product is the same or better, great. But researching and getting a bunch of conflicting opinions as to what will work without trashing a $7,000 motor or a more expensive trans-axle to save $30 worth of oil doesn't make sense to me. If it says another product is acceptable in the owners manual, fine, I would get it to if it is cheaper. I already bought an average product with a 60 % markup, a John Deere, so whats a couple more filters. ![]()
