Provides protection against rust and corrosion, particularly during low-use periods.High tolerance to water contamination without sludge formation, which could cause filter clogging and hydraulic system malfunction –anti-oxidation capability allows oil to work properly at high temperatures, helping keep transmissions and hydraulic system moving parts clean.Superior wet-clutch performance smoothes clutch operation.Reduces wet-brake chatter, assures high braking capacity.Oil that is too light can cause increased wear too heavy will cause sluggish operation and lower mechanical efficiency. For Hy-Gard to work efficiently, it must flow readily through any part of the system. A polymeric viscosity improver helps Hy-Gard retain its proper viscosity over a wide range of operating temperatures.Performance-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.Low-Viscosity Hy-Gard is compatible with hydrostatic fluid and can be added to systems, which contain hydrostatic fluid.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. It also is used as a replacement for Hy-Gard in cold weather applications. Consult the machine’s operator’s manual to determine what machines require low-viscosity Hy-Gard. Low-Viscosity Hy-Gard is used for factory fill in many machines.The 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.It 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. Hy-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.
