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.
What grade of oil is Hy-Gard?
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.
Is J20C low viscosity?
J20C transmission oil offers a high viscosity meant for mild temperatures and hot days. As the outside weather and transmission heat up during daily use, the J20C oil will slowly lose viscosity as the temperature increases.
What is the best oil for hydrostatic transmission?
The fluid recommended for Hydro-Gear transmissions and pumps is a 20W-50 motor oil or 15W-50 synthetic motor oil.
What is John Deere Hy-Gard equivalent to? – Related Questions
What kind of oil goes in a John Deere hydrostatic transmission?
John Deere suggests hydraulic fluid meeting the John Deere “J20C” specification or 10W-30 motor oil. The AMSOIL products that meets this spec are AMSOIL Synthetic Tractor Hydraulic/Transmission Oil or AMSOIL Small Engine Synthetic 10W-30 Motor Oil.
Can I use 20w50 in a hydrostatic transmission?
For use in hydrostatic transmissions in zero turn, stand on and riding mowers requiring a high viscosity transmission fluid, either 20W-50 or 15W-50.
Can you use engine oil in hydrostatic transmission?
Conclusion. There’s no question that motor oil will work in mower hydrostatic transmissions that allow its use. But a dedicated hydrostatic transmission oil contains specific anti-foaming, anti-rust, anti-oxidation and anti-wear ingredients.
Is 20w50 oil the same as hydraulic oil?
A: There is no such thing as 20w50 hydraulic oil. They are using 20w50 engine oil. Example mercury marine uses 30w engine oil as hydraulic fluid for the K-plane trim tab systems. Hopefully this helps!
Is hydrostatic oil the same as hydraulic oil?
Hydrostatic Fluid is an exceptional quality hydrostatic and anti-wear ISO 46 multi-viscosity hydraulic oil containing additional additives to prevent wear. It is designed to exceed the performance requirements of many major hydrostatic and hydraulic pump manufacturers.
How often should you change hydrostatic transmission fluid?
The HT-1000 transmission fluid only needs to be changed once every 1000 hours, as opposed to as early as 500 hours with other brands. Our Hydrostatic Transmission Fluid HT-1000™ is a synthetic transmission oil engineered to provide maximum durability and long life for heavy-duty hydrostatic drive systems.
How often should you change hydraulic oil in a John Deere tractor?
Change after first 100 hours, then after every 200 hours, if tractor is not equipped with hydraulic filter, or else if tractor is not equipped with hydraulic filter then change after 600 hours. Service after 200 hours or annually, whichever comes first. Service as required.
What happens if u dont change transmission fluid?
If you don’t replace your transmission fluid, it will break down much like engine oil and lose its lubricating and cleaning properties. This leads to high temperatures, sludge buildup, and excess friction, which can damage the internal clutches that shift the gears.
What causes a hydrostatic transmission to slip?
Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself. In the transmission section of your operator’s manual, you’ll find a section that covers oil viscosity.
What happens if you push a hydrostatic mower?
You can’t push hydrostatic mowers without disengaging the transmission. Fluid is pumped to the wheels to turn them, so if the motor is off the pump is too and the wheels won’t turn. If you push the mower when it’s off, the fluid already at the wheels will flow back into the pump and damage it.
Can you damage a hydrostatic transmission?
If you attempt to push a tractor with a hydrostatic transmission, it causes fluid to move backward through the pump and can damage the seals. You must disconnect the drive before moving your lawn tractor.
