NOTICE: Change hydraulic fluid and filter after the first 75 hours of operation and then every 400 hours after .
What kind of oil do you put in a 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.
Do you need to change hydrostatic transmission fluid?
Replacing hydrostatic fluid is normally not necessary, unless the drive system is in need of some other internal service or repair .
Do riding mowers need transmission fluid?
Which oil goes into the hydrostatic transmission? Transmissions on the consumer zero turns and tractors are maintenance free, unless regular service is notated in the owners manual, and do not require regular fluid change .
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.
How long does hydrostatic fluid last?
The answer depends on many factors. Although the life of a hydraulic oil really depends on many variables, including quality of oil, operating conditions, and potential contamination, a good quality hydraulic oil should last at least 6 months if conditions are not severe .
How many hours is a hydrostatic transmission good for?
I believe that most hystat transmissions on smaller tractors should last 3 – 5000 hours plus if they have been serviced regularly (strictly my opinion, not based on data).
How much oil does a hydrostatic transmission take?

Can you put hydraulic oil in a 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 .
Can you use motor oil in place 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.
When should I use 20w50 oil?
What Is 20W-50 Oil Used For? 20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles . Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.
What kind of oil goes in Cub Cadet hydrostatic transmission?
If your Cub Cadet calls for “Cub Cadet Drive System Fluid Plus” in the transmission, it is OK to use Rotella 5w-40 or 15w-40 . However, you cannot use a motor oil filter since it will not let you purge the air out of the system.
Why do hydrostatic transmissions whine?
They said it has something to do with air getting mixed with the hydraulic fluid at higher speeds , then when you go back to idle the air collects in larger bubbles and makes that sound when it moves thru the pips. They say all tractors with the Hydrostatic Transmission will make this sound.
What are the disadvantages of hydrostatic transmission?
- Overly Responsive. Vehicles with a hydrostatic transmission have to be driven with extreme care when it comes to acceleration and gears. ...
- Inefficient. HST is not known for engine efficiency. ...
- Expensive. HST vehicles are oil guzzlers.
Is hydrostatic fluid the same as transmission fluid?
Transmission fluid is a type of hydraulic fluid . The transmission fluid is a medium that transmits power from the engine to the transmission. Other types of hydraulic fluid include mulitgrade engine oil and conventional, antiwear hydraulic oil.
What oil goes in a tractor gearbox?
Valvoline UTTO and UNITRAC are premium fluids for lubrication of tractor transmissions and other equipment. UTTO and UNITRAC are recommended for a range of tractor components and possess the approval of leading heavy duty agricultural machinery and equipment manufacturers.
Is 20w50 oil the same as hydraulic oil?
Yes you can. Motor oil and hydraulic oil are the same thing , they are oil. 1 of 1 found this helpful.
Does hydraulic oil go off?
No matter how clean you keep your oil, it will eventually go bad . Keeping your hydraulic fluids clean is no doubt important, but even with the best filters and fluids, over time any kind of oil will degrade and need to be replaced.
What happens if you run out of hydraulic fluid?
Worn out components within the system can also lead to excessive temperatures due to internal leakage . If there are restrictions in the line or dirty filters, hot hydraulic fluid will result. If hydraulic fluid viscosity is too low, it can lead to overheating as well.
How often should you change hydraulic oil in a tractor?
Most tractor manufacturers recommend: Check hydraulic fluid levels every 50 hours of use and add oil as necessary.
What is the advantage of hydrostatic transmission?
Advantages of a hydrostatic transmission include power transmission to remote areas, infinitely variable speed control, self-overload protection, reverse rotation capability, dynamic braking, and a high power-to-weight ratio .
Why does my hydrostatic transmission won’t move?
A hydrostatic lawn mower may not move because of a bad drive belt; bad tensioner pulley; broke tensioner spring; old or low hydraulic fluid; hot hydraulic fluid; air in the hydraulic system; or the drive release handles are in the “released” position.
Are hydrostatic transmissions good?
If your tractor will be primarily used for lawn and garden chores or with attachments that don’t require consistent speed, a hydrostatic transmission tractor may be the best choice and offers a variety of benefits. Easy to operate – simplified high-to-low lever to shift, no clutch to depress.
