Founded about thirty years ago, Hydro-Gear is one of the leading manufacturers of drive systems for various kinds of lawn mowers, garden tractors, snow throwers, and other equipment. Its assortment is large enough and includes hydrostatic transmissions and transaxles, gear reduction drives, variable displacement piston pumps and wheel motors, electric drive systems, and numerous replacement parts. All of them are made with high precision and quality in mind and can be found in lots of mowers and other gardening machinery that come from different manufacturers Hydro-Gear collaborates with.
As for riding mowers available on the market, they can be fitted with a manual, automatic, or hydrostatic transmission. Essentially, the last option is also automatic, but instead of traditional belts, it uses fluid to transfer engine power and has some benefits including a smoother ride, longer service life, and fewer requirements for maintenance. A typical Hydro-Gear transmission of this type includes a variable displacement axial piston pump that sends power to a bi-directional piston hydraulic motor. The pump is usually powered by a small gasoline motor via belt drive. In such a setup, the engine can operate in the most effective mode, as the vehicle's speed and direction are controlled with the help of the transmission.
Quite often, the whole transmission assembly is called a transaxle, as, aside from a gearbox, it also contains a differential and drive axles. A zero-turn mower usually has two transaxles, one per each drive wheel. To keep your transaxles in good working condition, you will need to change oil and filter, and you can choose a special Hydro-Gear filter available individually or in the brand's service kits that also include oil and a pump. A vast array of these and other Hydro-Gear parts is available in our online store. Here you will find Hydro-Gear fans, cylinder block kits, bearings, shafts, seals, gaskets, and plenty of other goods to keep your equipment in top shape.
