Common Cub Cadet RZT 50 Problems

1. Prolonged Engine Cranking:

Problem: One problem I often encountered with my Cub Cadet RZT 50 was prolonged engine cranking when trying to start it up.

DIY Solution: Check the battery and connections to ensure they’re in good condition. Clean any corrosion on the terminals and recharge or replace the battery as needed.

Professional Solution: If the DIY steps don’t work, it might be an issue with the starter motor or the ignition system. Hiring a professional mechanic can help diagnose the problem and replace any faulty components.

2. Uneven Cutting:

Problem: Another issue I faced was uneven cutting, where the mower left some patches of grass longer than others.

DIY Solution: First, ensure the blades are sharp and balanced. If they aren’t, sharpen or replace them. Also, check the deck level and adjust it properly to ensure even cutting. Professional Solution: If you’re unsure how to level the deck or can’t resolve the problem on your own, consider hiring a professional to service the mower and perform any necessary adjustments.

3. PTO Belt Problems:

Problem: A common problem that my relative farmer faced was PTO (Power Take-Off) belt issues, which caused the mower deck to stop engaging.

DIY Solution: Check the PTO belt for wear or damage, and replace it if necessary. Make sure it’s properly routed and tensioned according to the manufacturer’s guidelines.

Professional Solution: If replacing the belt doesn’t solve the problem, there might be an issue with the PTO clutch or other components. A professional can diagnose and fix the problem more accurately.

4. Hydrostatic Transmission Troubles:

Problem: I once experienced issues with the hydrostatic transmission, where the tractor wouldn’t move smoothly or at all.

DIY Solution: Check the transmission fluid level and condition. If it’s low or contaminated, refill or replace it with the recommended fluid type.

Professional Solution: If the transmission problem persists, it might require more complex repairs or replacements. Seek help from a professional mechanic with expertise in hydrostatic transmissions.

5. Steering Problems:

Problem: My relative farmer faced steering problems, where the tractor’s controls were unresponsive or difficult to operate.

DIY Solution: Inspect the steering linkage and connections for any wear or damage. Lubricate the moving parts and ensure they move freely.

Professional Solution: If the steering issue continues, it might be due to problems with the steering system, and a professional technician can diagnose and fix it.

Costing for Hiring Professionals: Hiring professionals to address these issues can vary in cost depending on the complexity of the problem and your location. On average, you can expect to pay anywhere from $50 to $150 per hour for labor charges. Additionally, parts replacement or repairs may have additional costs. It’s essential to inquire about pricing beforehand and get quotes from reputable repair shops or mechanics.


How often should I sharpen the mower blades?

Ideally, you should sharpen the mower blades after every 25 hours of use or at the beginning of each mowing season. Keeping the blades sharp ensures a clean and even cut.

Can I use regular engine oil in the Cub Cadet RZT 50?

No, it’s crucial to use the recommended engine oil type as specified in the owner’s manual. Using the wrong oil can lead to engine damage and void the warranty.

What’s the best way to store the Cub Cadet RZT 50 during winter?

Before storing the tractor for the winter, clean it thoroughly, and remove any grass clippings and debris. Also, store it in a cool, dry place, and consider using a fuel stabilizer to prevent fuel-related issues during storage.


So there you have it, folks! My personal experiences and those of my relative farmer with the Cub Cadet RZT 50. It’s a remarkable tractor that can make your mowing tasks more manageable, but like any machinery, it comes with its own set of challenges.
