What fluid goes in a Craftsman hydrostatic transmission?

Kubota, Husqvarna and HydroGear manufacture most hydrostatic transmissions used in the U.S.; their products are installed by Sears in its Craftsman range, and by John Deere. The transmissions work using hydraulic oil.

What oil do I use in my hydrostatic transmission?

The fluid recommended for Hydro-Gear transmissions and pumps is a 20W-50 motor oil or 15W-50 synthetic motor oil. If the machine has oil reservoirs, they are mounted to the frame behind the seat, for easy access and oil level check accessibility.

Is hydrostatic oil and hydraulic oil the same?

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.

Is hydraulic fluid the same as transmission fluid?

All Answers (3) ATFs are usually less viscous and designed to work under lower pressures and temperatures than hydraulic fluids. The operating temperature range of hydraulic fluids is larger i.e. they maintain their viscosity better in a broader temperature range. Also hydraulic fluids are very pure compared to ATFs.

Is hydrostatic oil the same as motor oil?

Hydrostatic transmission oil is designed to withstand gear lubrication to a much greater extent than motor oil. This means that dedicated transmission oil has a superior ability to maintain its original viscosity and provide more reliable wear protection over the long term.

What is hydrostatic hydraulic fluid?

Hydrostatic Fluid is a multi-viscosity oil formulated with an extremely shear stable viscosity modifier. It provides exceptional low temperature properties enabling performance over a wide range of startup and operating temperatures.

Can you use mOtor oil instead of hydraulic fluid?

Engine oil can work satisfactorily as a hydraulic fluid. However, if a multigrade engine oil is being used in the hydraulic system specifically for its high viscosity index (VI), then it’s not the correct solution. The reason is the additives used to improve viscosity index.

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 put hydraulic fluid in an automatic transmission?

Most automatic transmission systems use automatic transmission fluid (ATF) as a hydraulic fluid, as well as a gear lubricant.
