Common Signs Of Transmission Problems With Zero Turn Mowers
Grinding gears, starting and stopping during operation, and the wheels not rotating with the pulley are common signs that your mower’s transmission is breaking down. Zero turn hydrostatic transmission problems can start with air in the system, a condition known as cavitation. When the pump is full of air instead of oil, it can’t generate the pressure needed to provide power. This is pretty common in zero-turn mower transmissions. To diagnose a bad hydrostatic transmission, you can 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. It’s important to fix these hydrostatic transmission problems fast to ensure smooth operation of your mower.
Cavitation: A Common Problem

| Air in the system instead of oil: One of the common transmission problems in Cub Cadet RZT 50 zero-turn mowers is cavitation. This occurs when there is air present in the system rather than oil. Cavitation prevents the necessary pressure from being generated, resulting in transmission issues. It is important to check for air in the system and resolve it to ensure proper functioning of the mower’s transmission. |
Diagnosing Hydrostatic Transmission Issues
|
When diagnosing hydrostatic transmission issues, there are several key steps to take. First, check the oil level in the tank to ensure it is at the proper level. Inspect the heat exchanger to make sure it is not dirty or clogged, as this can cause overheating. Next, inspect the inline pressure filters to see if they are blocked or need to be replaced. It is also important to check the crossport relief valves to ensure they are functioning properly. Finally, examine the pump and motor case drains for excessive bypassing, which can indicate a problem. By following these steps, you can effectively diagnose and address hydrostatic transmission issues in your Cub Cadet Rzt 50. |
Removing And Replacing Parts
When it comes to addressing Cub Cadet Rzt 50 transmission problems, removing and replacing parts is a crucial step. One of the first parts to remove is the pulley and lever. Carefully follow these steps:
- Remove the pulley by following the instructions provided in this YouTube video.
- Next, remove the bolts that hold the center section in place. Refer to this YouTube video for a visual guide.
- After removing the bolts, sanding the results and inspecting the input shaft is necessary. Refer to the same YouTube video for guidance.
- Finally, install all the seals and the emergency brake shaft seal as outlined in the video.
Following these steps can help address transmission problems and ensure optimal performance of your Cub Cadet Rzt 50 mower.
Reassembling And Adjustments

| After completing the necessary repairs on your Cub Cadet Rzt 50 transmission, it’s time to reassemble and make the proper adjustments. Here are the steps to follow: |
- Fill transmission: Make sure to fill the transmission with the appropriate fluid as recommended by the manufacturer. This ensures proper lubrication and operation of the transmission.
- Install bypass valve lever: Place the bypass valve lever in its designated position. This allows for the free movement of the mower without engaging the transmission.
- Adjust linkage for proper operation: Check the linkage connecting the transmission to the control lever. Adjust it as necessary to ensure smooth and precise operation of the transmission.
By following these steps, you can ensure that your Cub Cadet Rzt 50 transmission is reassembled correctly and adjusted for optimal performance. Remember to refer to the manufacturer’s instructions for specific details and guidelines.
