Solution
To fix the problem of the mower not starting, you have to ensure that the engine is functioning properly and has no errors.
So, check the carburetor, filters, fuel tank, fuel cap, and injector.
If any of them is dirty or damaged, then fix the problem. You can consider buying this fuel cap if it is broken.
Inspect the oil for quantity and quality. If it is stale or contaminated, replace it without thinking for a second.
And if the fluid level is low, pour more fuel to make it sufficient. Remember to check the spark plug and battery as well, and if they have issues resolve them.
Plus, don’t forget to ensure that your mower brakes are in an engaging position. And the knob has disengaged.
It’s also crucial to accurately adjust the throttle control levers.
2. Engine Working Erratically
If the engine is giving an erratic performance, then it can surely be highly depressing.
Here I’ll enlist some causes of the erratic behavior of the engine:
The engine runs while the choke is ‘ON.’
- Defective or loose spark plug
- Stale fuel
- Clogged fuel line
- Viscous oil
Solution
To sort out this problem, inspect the choke system and ensure its controls are activated accurately.
And, when your mower engine is operating, the choke should never be on. Otherwise, the engine will show erratic behavior.
After that, check the fuel lines, and if they have become filthy, then it is imperative to clean them. Or if they are damaged, then replace them immediately.
The next crucial thing you have to do is check your mower’s spark plug. A faulty or dirty spark plug would never let your engine operate peacefully.
So, if the spark plug is damaged, change it, and if dirty, then cleaning will be enough to solve the problem.
If your engine is still performing erratically, oil viscosity might be the problem, so change the oil.

3. Engine Knock Down
Engine knocking down is another prevalent issue that Cub Cadet LT1050 customers have to tackle.
If you are dealing with this issue, overloading and overworking could be the potential causes.
Additionally, insufficient or low-octane fuel is also a reason. If the cooling fins of the mower are overheated, they can also induce this problem.
Another noteworthy cause of the engine knocking down is the slow-moving speed. Defective crankshaft and camshaft are some other possible reasons.
Solution
You have to inspect the fuel tank to get rid of this issue. If the fuel is stale, drain the tank and clean and refill it. Ensure fuel has premium quality.
Moreover, add more gasoline to the tank if the fuel is too low.
Also, make sure that your mower is not mowing at a slow speed. Instead, your mower should have a steady speed, not too fast or slow.
Check the crankshaft and camshaft as well, and if it is faulty, replace them without a second thought.
Lastly, fix the overheating issue of cooling fins and make sure the mower is not overloaded.
4. Engine Overheating
Overheating the engine and exhaust are common issues in the Cub Cadet LT1050 mower.
It can happen for multiple reasons, and if left unaddressed, it can damage the engine.
Some common causes include:
- Overloading
- Overworking
- Clogged air filter
- Dirty cooling fins
- Viscous fuel
Solution
To fix the issue, you have to properly clean the cooling fins if they are filthy and switch them with new ones if damaged.
If the cooling fins are broken or dirty, they won’t cool the engine. Resultantly, the engine will overheat.
You should also clean the air filter; if it has any defects, then replacement is the only way to sort out the issue.
The engine will not get enough air if the air filter is clogged or damaged.
Another imperative thing you need to consider is the load. Never load the mower more than the recommended level.

- Faulty or misadjusted choke
- Air gap issue in the ignition coil
- Defective spark plug

After that, ensure that your mower engine has no surplus oil. You need to adjust the carburetor as well.
And if you figure out that the spark plug is arising, the issues clean or replace it according to condition.
Hopefully, this engine issue will end once you have done the aforementioned steps.
