There are several key features and functionalities that make John Deere Hy-Gard different from other hydraulic and transmission oils: Watch this video to see how John Deere Hy-Gard compares to other fluids in the marketplace. How Does Hy-Gard Stack Up to Other Fluids? You can see the difference in thickness for yourself. Low Viscosity Hy-Gard is designed to flow at even lower temperatures than specified by JDM J20, which is why it flows more freely at -36 degrees Celsius. This includes those with wet brakes and wet clutches. Typically, it’s recommended for John Deere machines with either common system reservoirs or separate transmission and hydraulic systems.

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

John Deere Hy-Gard™ Cold Pour does just that. In order to meet these specifications, fluids must pour at -36 degrees Celsius (-32 degrees Fahrenheit). John Deere JDM J20 specification lists temperatures that the transmission and hydraulic fluids should flow. Thick oil not only wastes fuel but, even worse, it creates increased load and causes poor hydraulic function. Even if your machine does start, components in the transmission and hydraulic system will be rotating oil that is thick. This puts unnecessary stress other parts like the starter and battery. Why are cold flow properties so extremely important for transmission and hydraulic fluids? If oil is too thick at cold temperatures, your machine may not start properly – or at all for that matter.
