For Hy-Gard to work efficiently, it must flow readily through any part of the system. Features and benefitsPerformance-tested both in lab and in field and approved by John Deere engineers to meet increased demands for performance and protection of transmissions and hydraulic oils.A polymeric viscosity improver helps Hy-Gard retain its proper viscosity over a wide range of operating temperatures. It also is used as a replacement for Hy-Gard in cold weather applications.Low-Viscosity Hy-Gard replaces the John Deere All-Weather Hydrostatic Fluid and should be used as a direct replacement for all applications recommending hydrostatic fluid.Low-Viscosity Hy-Gard is compatible with hydrostatic fluid and can be added to systems, which contain hydrostatic fluid. Consult the machine’s operator’s manual to determine what machines require low-viscosity Hy-Gard. ApplicationsThe exclusive Hy-Gard formula was designed for use in John Deere equipment however, it can also be used in many non-John Deere transmission and hydraulic systems.Low-Viscosity Hy-Gard is used for factory fill in many machines. Low-Viscosity Hy-Gard has the same performance specifications as Hy-Gard and can be used as a replacement for Hy-Gard in cold weather.
Hy-Gard may be used in many applications specifying either of these grades. Hy-Gard viscosity places it between ISO 46 and 68 grades. Low-Viscosity Hy-Gard has an ISO 32 viscosity grade.
Both Hy-Gard fluids are multi-viscosity fluids with high-viscosity index.
John Deere Hy-Gard Hydraulic Transmission Oil 5 Litres VC81824-005Hy-Gard and low-viscosity Hy-Gard transmission and hydraulic oils are unique oils developed by John Deere engineers to meet the exact needs of John Deere machines.
