How To Tell Transmission Type On Garden Tractor?

What is the difference between automatic and hydrostatic transmission?

An automatic transmission performs much like the transmission in a car — you control speed with the gas pedal. A hydrostatic transmission works like an automatic transmission, but uses fluid rather than belts to transfer power from the engine to the wheels.

What is hydrostatic transmission on a lawn tractor?

Lawn mowers with hydrostatic transmissions allow you to mow through a wide range of speeds, instead of operating with preset gear speeds. Hydrostatic lawn mower transmissions combine a hydraulic pump with a hydraulic motor to power the machine.

How do I know if my transmission is hydrostatic?

Identifying your Product: All Hydro -Gear® products can be identified by the label attached to the product depicting the model and serial number. You will need this information when asking for specific assistance with service and/or repair needs.

Where is the model number on a Tuff Torq Transmission?

Answer: It is highly recommended that you use Tuff Torq approved sealant. Question: Where is the serial number located? Answer: It is located on the back portion of the transaxle on a white label. Occasionally, a duplicate label will be located under the seat on the mower.

What type of fluid goes 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.

Does a hydrostatic transmission have a clutch?

With a hydrostatic transmission there is no clutch, only a neutral (center) position that is used to start the tractor and idle. For simplicity sake we’ll focus on foot controlled hydrostat variants where forward motion begins by depressing a pedal. To increase ground speed, the pedal is further depressed.

How much does it cost to replace a hydrostatic transmission?

Additionally, how much does it cost to replace a hydrostatic transmission? Transmissions are the next highest repair for riding lawn mowers. If you have a hydrostatic transmission built in the past 15 years you can expect to pay somewhere in the area of $200 for a new transmission.

Do hydrostatic transmissions wear out?

Not performing routine maintenance. The hydro has relief valves, so you cant work it past its designed intent, but you certainly can damage them if you try, just like a gear transmission. You can stress it by being rough with it, but really, these last every bit as long as gear transmissions.

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.

How do you troubleshoot a hydrostatic transmission?

Troubleshooting Hydrostatic Drives If the system is overheating, check the oil level in the tank, inspect the heat exchanger, check the inline pressure filters, inspect the crossport relief valves, and check the pump and motor case drains for excessive bypassing.

What makes a transmission hydrostatic?

A hydrostatic transmission (HST) exists any time a hydraulic pump is connected to and dedicated to one or more hydraulic motors. These transmissions produce a speed-torque characteristic that is hyperbolic, and they are used primarily to prevent lugging of the prime mover.

What is the difference between hydraulic and hydrostatic?

“A hydraulic drive system is a quasi- hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery. The term hydrostatic refers to the transfer of energy from pressure differences, not from the kinetic energy of the flow.

What oil goes in a Tuff Torq Transmission?

the original 10w30 oil if you are changing the oil or doing internal repairs to the unit. If adding to the original oil to bring up to the proper level, refer to this page or the owner’s manual for the factory oil spec. 2. Hy-Gard High & Low Viscosity are John Deere products.

What is a K46 transmission?

The K46 is the most popular integrated hydrostatic transaxle (IHT) in the world…and for good reason. This power unit has all the features and performance of much larger and more expensive transaxles, all at a very affordable cost and in a small and purpose-focused design.

What is Tuff Tech Oil?

The new Tuff Tech ™ premium hydrostatic drive fluid is not just another motor oil. It has been specifically and uniquely designed and formulated to provide optimum performance and protection within the working parameters of a hydrostatic transaxle. ≈15% less wear than standard oil in wear tests.
