If it is winter, then this is the best time for sun basking. You might not be able to do it because your cub cadet mower is not starting, and you can’t spend time with the family on the lawn that looks like a jungle.
You want to clean the lawn with the mower, but the mower won’t start.
It is frustrating, but you don’t need to worry because cub cadet lawn mower starting problems are because of some simple issues.
See our article on how to grow grass with small dogs.
In this article, we will discuss cub cadet starting problems and some of their fixations, so continue to read to learn about the starting problems.
Cub Cadet Starting Problems
If your Cub Cadet riding lawn mower won’t start, there are several things you can do to troubleshoot the problem:
- Check the fuel level and add more gas if needed.
- Check the oil level and add more oil if needed.
- Check the battery to see if it needs to be charged.
If none of these things fix the problem, you may need to take the mower to a repair shop.
Low Oil Level
If your Cub Cadet lawn mower won’t start, one of the first things you should check is the oil level. If the oil is too low, it can cause the engine to seize up, making it impossible to start.
How To Check Oil Level:
To check the oil level, remove the dipstick and see where the oil falls on the dipstick. You’ll need to add more oil if it’s below the “full” line.
Bad And Old Fuel
If your Cub Cadet won’t start, the first thing to check is the gas tank. Ensure that there is enough fuel in the tank and fresh fuel. If the fuel is old, it may have gone not good and clogged up the carburetor. Also, ensure that the gas shut-off valve is in the “on” position.
- Make use of a gasoline siphon pump to remove the old and bad fuel from the fuel tank.
- To clear and remove the moisture from the fuel system, apply new fuel and a fuel additive.
If the gas tank is full and the fuel is fresh, then the spark plug is next to check. The spark plug could be fouled or damaged and needs to be replaced.
Spark Plug Is Damaged
If there is no spark at all, then it’s likely an electrical problem. If there is only a faint glow of an orange-ash color in your engine compartment, you may have a bad wire or connector along the path from the battery to the distributor cap.
Over time, spark plugs can become fouled or damaged, preventing them from firing properly.
- Check your spark plug’s ceramic insulator for cracks or symptoms of carbon buildup by removing it.
- Clean or replace the spark plugs and try starting the engine again.
Air Filter Is Clogged
Your Cub Cadet’s engine needs air to function. The engine may run out of air if your air filter becomes very dusty since air will no longer be able to travel through the filter. The lawnmower engine won’t start if it does not get enough air.
A dirty or clogged air filter will restrict airflow to the engine, making it difficult for the engine to start and run. It could start to burn and draw any available air from the crankcase, which could seriously harm the engine.
- Remove a sheet air filter from the housing and clean it.
- Take care to avoid dumping any loose debris into the air intake when removing it.
- Use a clean, dry cloth to remove leftover dirt from the housing.
- Tap the filter against such a hard surface to remove any extra dirt.
- To clear the air filter, avoid using an air compressor.
- Hold the filter up to the light after you have removed as much dirt as you can to see whether you can see the light coming through the paper.
You should regularly check and clean the air filter as part of your Cub Cadet’s routine maintenance.
Fuel Filter Is Clogged
The fuel filter acts as a barrier to stop dirt and debris from entering the engine by straining the fuel. Please verify that the fuel flowing into the filter flows out of it. If it doesn’t, you’ll need to replace it because it’s probably plugged and won’t allow your Cub Cadet to start.
- If your fuel flow appears to stop at the fuel filter, fix it by replacing it.
- If necessary, replace the oil filter on the Cub Cadet.
- The filtration must be mounted with the sign on the filter pointing in the fuel flow direction.
Cub Cadet Fuel Cap Is Faulty
There is a vent in your gasoline cap. The gasoline tank will create a vacuum if this vent becomes blocked, stopping the Cub Cadet mower from collecting gas from the fuel tank.
Remove the gas cap from your mower and try starting it to see if that solves your starting issue. If the mower starts when you remove the gasoline cap, then install the cap again.
You are anticipating the mower splattering and shutting off due to fuel shortage. If so, take off the cap to check if the lawnmower will restart. Now that it is confirmed, the issue is because of the gasoline cap.
- To fix this issue, all you need to do is to change the fuel cap with a new one.
Issue With Starter Relay
This device controls when your tractor turns on its power source—meaning that you’ll still get wheels turning if there isn’t any fuel or water in its tank. On most tractors like this one, at least one relay needs fixing before anything else will work properly again – though some people report success after replacing just one component.
