John Deere Hy-Gard Transmission and Hydraulic Oil (2 1/2 Gallon) TY22062 An exclusive formulation, specifically designed to protect John Deere transmissions, final drives, and hydraulic systems. 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. Hy-Gard viscosity places it between ISO 46 and 68 grades. Hy-Gard may be used in many applications specifying either of these grades. Applications: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 systemsFeatures and Bennefits: 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 A polymeric viscosity improver helps Hy-Gard retain its proper viscosity over a wide range of operating temperatures. For Hy-Gard to work efficiently, it must flow readily through any part of the system. Oil that is too light can cause increased wear; too heavy will cause sluggish operation and lower mechanical efficiency. Reduces wet-brake chatter, assures high braking capacity Superior wet-clutch performance smoothes clutch operation 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 Provides protection against rust and corrosion, particularly during low-use periods Anti-wear additives keep gear and bearing wear to a minimum � extreme pressure film in Hy-Gard helps prevent metal-to-metal contact Hy-Gard oil can be used ...
