Hydro Gear Transmission
Hydro Gear is a brand that specializes in the manufacturing of hydrostatic transmissions.
Hydrostatic transmissions, also known as hydrostatic drive systems, are a type of transmission commonly used in lawn tractors, riding mowers, and other small vehicles.
Unlike traditional mechanical transmissions that use gears and clutches, hydrostatic transmissions use hydraulic principles to transmit power from the engine to the wheels.
They consist of a hydraulic pump and motor connected by hydraulic fluid-filled lines.
Typically, the engine powers the hydrostatic pump, which converts mechanical force into hydraulic pressure.
This pressurized fluid is then directed to the hydraulic motor, which converts the hydraulic pressure back into mechanical power to drive the vehicle’s wheels.
One of the key advantages of hydrostatic transmissions is their ability to provide smooth and seamless acceleration and speed control.
They offer infinite speed variability, allowing for precise control over the vehicle’s speed without the need for gear shifting.

How do you fill a Tuff Torq K46?
To fill a Tuff Torq K46 transmission, you will need the following supplies:
- Transmission fluid specifically designed for use in a Tuff Torq K46 transmission. This fluid is available from Tuff Torq or from a dealer that sells Tuff Torq products.
- A transmission fluid pump or a hand-held vacuum pump with a transmission fluid hose attachment.
- A clean container to catch the old transmission fluid as it is removed from the transmission.
- A drain pan to catch any spillage.
To begin, first, locate the fill and drain plugs on the transmission. The fill plug is usually located on the side of the transmission near the top, while the drain plug is located at the bottom of the transmission.
Next, place the drain pan under the transmission and remove the drain plug to allow the old fluid to drain out.
Once all of the fluid has drained out, replace the drain plug and wipe away any spillage.
Next, attach the fluid pump or vacuum pump to the fill plug and slowly add the new transmission fluid to the transmission.
It is important to add the fluid slowly to allow it to properly circulate through the transmission.
Continue adding fluid until it starts to come out of the fill plug hole. This will indicate that the transmission is full.
Once the transmission is full, replace the fill plug and check the fluid level using the dipstick (if equipped). If the fluid level is low, add more fluid as needed.
It is important to use the correct type and amount of fluid in the transmission to ensure proper operation.
