![]() Superior high temperature performance helps ensure fewer deposits and a longer life.RES 10060 for John Deere factory and aftermarket standards.JDM J20C (regular)/JDM J20D (low viscosity) – minimum specs.Gearboxes with hydraulic derived systems.Transmissions and differential units with immersed “wet” brakes.This top-of-the-line lubricant provides smooth performance under a wide range of operating conditions for: So it’s easy for you to choose the right oil for your agricultural and turf equipment. And Hy-Gard oil is a sophisticated Universal Tractor Transmission Oil (UTTO). It not only meets John Deere equipment standards, it exceeds them. Protect your hydraulics and transmissions with the best oil for both: Hy-Gard. Compact Tractor Attachments & Accessories.Low-Viscosity Hy-Gard and Hy-Gard are compatible with hydrostatic oil and can be added to systems that contain hydrostatic oil. Low-Viscosity Hy-Gard should be used in all applications calling for JDM J20D.Note: Hy-Gard should be used in all applications calling for JDM J20C. Hy-Gard oil can be used in most applications calling for 10W-30 or 5W-30 engine oil for transmission and hydraulic oils.Prevents foam and water damage to all internal parts.Prevents the formation of deposits on all internal parts.Withstands extreme pressures in hydraulic system without breaking down.Provides proper friction for brakes to ensure low chatter, long life, and high capacity.Provides proper friction for clutches to engage and absorb shock loads without excessive slipping or abrupt shifts.Provides proper friction for wet brakes to give maximum stopping performance with minimum chatter.Provides wear and corrosion protection for hydraulic pump.Prevents wear of high-torque, heavy-loaded gears and bearings.To understand the complexity of transmission/hydraulic oil, let’s review its functions: Anti-wear additives keep gear and bearing wear to a minimum – extreme pressure film in Hy-Gard helps prevent metal-to-metal contact.īecause transmission and hydraulic oil must perform many different tasks at the same time, there is very little margin for error.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.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. ![]() 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.
