Solutions To Common Cub Cadet RZT 50 Problems

Coping with a problematic mower is surely no less than solving a math paper. And even harder when you have zero knowledge.
So, to make this challenge a bit easier, I will discuss common problems and their solutions here.
1. Starting Problem

Doubtlessly, it is mind-boggling to deal with a mover that is not starting.
But there is no need to take tension as this issue can usually be sorted out at home.
First, let’s explore the causes of this problem so it would become easy to fix it.
Common causes of starting problems include:
- Fuel related issues
- Fuel system problems
- Bad spark plug
- Faulty solenoid
- Defective battery
- Clogged carburetor
The safety interlock system is not activated properly
Solution
To solve the issue, the first and foremost thing you need to do is check the oil.
Ensure that the fuel’s ethanol content is less than 10%. And the fuel must have 87-grade octane.
You should also follow a routine that involves an oil change every month.
Otherwise, if the oil sits in the tank for too long, it may break down. So, change it regularly.
Also, check the fuel cap, fuel pump, and fuel filter. If any of them is dirty, then clean it. And if broken, then simply change them.
Some other parts you must check include the solenoid, carburetor, spark plug, and battery.
If the solenoid begins to generate a bustling voice when you operate the mower, it shows that it’s defective and needs to be changed.
So, check the spark plug and ensure it is not clogged, broken, or loose. If it has either of these issues, fix them.
After that, check the battery, and if you notice that it has corroded terminals or loose or damaged wiring, then resolve this issue.
Lastly, make sure the safety interlock system is accurately activated.

2. PTO System Issue
A PTO (Power Take Off) system should be error-free to deliver top-notch performance.
But if any component of this system, such as the PTO switch, PTO clutch, or clutch cable, is faulty, then the blades will be unable to engage.
Solution
To eliminate this problem, you have to ensure that the PTO switch is turned on and has no fault. If it is defective, then replacement is the right solution.
Once you have confirmed it’s working fine, check the PTO belt.
A loose or broken belt can not perform the function perfectly, so tighten or replace it according to need.
If there is no issue with either of them, you must check the PTO clutch and cable.
And if they are broken, then replace them. It will definitely put an end to the PTO system issues.
3. Uneven Cutting
Uneven cutting is another problem that Cub Cadet RZT 50 customers may have to face.
Honestly, no lawn deserves to look filthy and ugly due to uneven cuts. So, diagnosing the factors that induce these issues is extremely significant.
A lawn mower cutting uneven grass may have blunt or worn-out blades.
Additionally, unlevelled or contaminated decks can play a big role in the appearance of this trouble.
Another noteworthy reason for the uneven cutting problem is damaged or deflated tires. Pressure imbalance in the tires is also a big culprit.
It’s also worth mentioning that apart from the errors in the machine, these issues may also arise due to wet grass or uneven lawn.

To overcome this problem, you have to check the blades. Normally they get damaged due to extreme usage. And you have to replace the Cub Cadet RZT 50 blades.
Besides that, they can get dull. So, to prevent this frustrating issue, it is crucial to sharpen them regularly.
Hopefully, the cutting problem will go away after replacing or sharpening the blades. But if they persist, then it’s time to check the tires and deck.
Here are some beneficial tips to solve this problem:
- Inflate the tires accurately
- Level the deck perfectly
- Ensure tires pressure is balanced
- Grass must be dry
- The lawn should be even
- Run the mower at full throttle mode
If your lawn is uneven, you can use a lawn roller. It will assist in curbing the uneven cutting issue.
4. Steering Problem
Steering problems can commonly appear in Cub Cadet RZT 50 mowers. Multiple causes can produce this issue.
If your mower steering wheel is not perfectly positioned, then it can contribute to inducing such issues.
Secondly, not properly secured or damaged linkages of the steering system can play a big role in the emergence of such problems.
Another culprit of steering problems is the damaged tires. Moreover, tires can also cause trouble if they have unequal pressure.
Mower deck improper leveling is another suspect for causing steering problems.

To resolve this issue, you have to inspect the steering wheel. You must ensure that your Cub Cadet RZT 50 steering wheel is positioned rightly in the center.
After that, ensure all the steering system connections are secure and undamaged. If broken, then replace it without any contemplation.
Once you finish it, inspect the tires and check whether they have uniform pressure.
And, if they are in a precarious condition, then you have to go to replace them. Don’t forget to align the deck as well.
5. Transmission System Issues
Another common issue in a Cub Cadet RZT 50 is transmission system issues.
Several defects in a transmission system may impact its performance and stop it from doing its work.
If fluid leaks or hydraulic fluid has low pressure, it can raise issues.
Moreover, transmission system slipping and inability to engage are other possible causes.
Solution
To get the optimal performance of the mower, it is important to resolve these issues quickly.
So, you need to check the hydraulic fluid. If it is stale or in low quantity, adding more fluid is crucial.
You need to inspect the transmission filter and replace it immediately if clogged.
The broken drive belt can also contribute to transmission issues, so change it. And don’t forget to tighten it if it is loose.
Lastly, check the tension of the pulleys; if it is insufficient, fix it.
6. Engine Issues
Engine issues are another prevalent problem that mower owners have to deal with often.
A wide range of issues can emerge in an engine and affect its performance and efficiency.
These include:
- Engine unable to start
- Engine stalling
- Overheating
- Poor performance
- Smoke emission
You should know the exact reason for each of these issues so that you pick the right solution method. Let me explain it one by one.
If your engine cannot start, the prime reasons behind these issues are a bad carburetor, a spark plug, and an old or empty fuel tank.
And if the engine is stalling, it usually happens due to stale and insufficient oil.
Additionally, if it is overheating, then clogged or dirty cooling fins are responsible for this trouble.
If the engine emits smoke, it’s due to dirty or damaged air filters.
When air filters are defective, they don’t give the required air to the engine. So, your mower consumes more gasoline which leads to smoke release.
Lastly, the carburetor’s wrong adjustment can be the most potential cause if the engine is not performing well.
