Tuff Torq K57 Parts Diagram

The Tuff Torq K57 is a hydrostatic transmission commonly used in lawn tractors and riding mowers. It consists of several key parts:


The transmission is housed within a sturdy casing that protects the internal components.

Input Shaft

The input shaft is connected to the engine’s driveshaft and transfers power to the transmission.

Hydrostatic Pump

The input shaft drives the hydrostatic pump, which pressurizes hydraulic fluid to produce power for the transmission.

Control Valve

The control valve regulates the flow of hydraulic fluid within the transmission, allowing for smooth speed and direction changes.

Hydraulic Motor

The hydraulic motor receives the pressurized fluid from the pump and converts it into rotational power to drive the wheels.

Axle Shafts

The axle shafts transmit the rotational power from the hydraulic motor to the wheels, propelling the lawn tractor or riding the mower forward or backward.


The transmission may also include filters to remove impurities from the hydraulic fluid, ensuring optimal performance and longevity of the system.

Tuff Torq K57 Oil Change

  • Safety first: Ensure that the engine is off and the transmission is in the neutral position. Engage the parking brake and remove the ignition key to prevent any accidental starts.
  • Locate the drain plug. Look for the drain plug on the bottom of the transmission housing. It is typically a square-headed plug.
  • Position the drain pan: Place the drain pan or container underneath the drain plug to catch the old oil.
  • Remove the drain plug. Use an appropriate wrench or socket to loosen and remove the drain plug. Allow the old oil to drain completely into the pan. You may need to tilt or tip the machine slightly to ensure all the oil drains out.
  • Replace the drain plug: Once all the oil has drained, clean the drain plug and inspect the washer or seal for damage. Replace it if necessary. Then, reinsert and tighten the drain plug securely.
  • Refill with new oil: Locate the oil fill port or dipstick on the top of the transmission. Remove the dipstick or open the fill port. Use a funnel to pour the recommended amount of new transmission oil into the transmission. Refer to the manufacturer’s guidelines for the correct oil capacity.
  • Check the oil level: After adding the oil, check the oil level using the dipstick or the oil level indicator. Ensure that the oil level is within the recommended range.
  • Secure the fill port or dipstick: Once the oil level is correct, close the fill port or reinsert the dipstick and secure it in place.
  • Clean up: Wipe away any oil spills or drips with rags or towels to prevent slipping hazards and keep the machine clean.
