Troubleshooting Cub Cadet Intellipower Problems

1. No Gas in Your Cub Cadet Fuel Tank Causes the Mower Not to Start

You may be wondering why something as modest as gas in a fuel tank appears on the list. Gas is an apparent reason why your Cub Cadet won’t turn on.

As apparent as it appears, you may be shocked to learn of the number of grievances I’ve gotten from various users about their starting problem when the culprit was no fuel in the lawn mower. 


Fill your empty tank with fresh unleaded gasoline with an octane grade of 87-grade or higher. Select a gas with an ethanol level no bigger than 10%.

2. Bad or Old Fuel in Your Cub Cadet Lawn Mower Causes a Starting Problem

Gas starts to erode, break down and become less beneficial after about 30 days. The ethanol used in gasoline brings about moisture.

This moisture, once it vanishes, abandons a gummy residue that can hinder your fuel system, including your fuel lines, filter, and carburetor.

It is essential to acquire fuel from a busy gas station and utilize it within a 30-day period. If you are incapable of using the said fuel within that time, you must put in a fuel additive to steady the fuel, so it lasts a little longer without breaking down.

3. Faulty Cub Cadet Fuel Cap Causes a Mower Not to Start

Your fuel cap has an outlet. 

When this vent gets clogged, your fuel tank will generate a vacuum deterring your Cub Cadet mower from drawing gas out of the fuel tank.

To examine whether your gas cap is the reason for your starting problem, take off the cap and turn on your mower. If the Cub Cadet that wouldn’t start starts at that moment, go ahead and fix the cap with the lawn mower still functioning.

You’ll wait for the mower to stutter and stop running from a lack of fuel. If it does, remove the cap and check if the mower will start up again.

When you encounter this kind of turning on and dying off from a fuel cap that is taken out and fixed on your Cub Cadet, you have an issue with the fuel cap.

4. Cub Cadet Has a Bad Spark Plug or Loose Connection 

Another explanation for why your Cub Cadet won’t function may be because of a bad spark plug connection or a bad spark plug. A plug that has carbon buildup or oil on the tip can foul out, prompting your engine to misfire and not come on.

Inspect the spark plug wire to confirm it’s making a good connection. Your spark plug must have the proper gaps according to the engine manufacturer’s specifications.

You can encounter starting and running problems with a loose spark plug wire or a wrongly gapped spark plug.

5. Plugged Cub Cadet Air Filter Causes Mower Not to Start

The engine in your Cub Cadet needs air to function. 

If your air filter gets very dirty, it can deprive the engine of air because air will no longer be able to go through the filter. A Cub Cadet engine that doesn’t get adequate air will not turn on.

When your air filter obstructs the airflow, the engine must locate air to go on with running. It may start overheating and pulling out what air it can get from the crankcase, which can substantially damage the engine.

6. Bad Cub Cadet Fuel Pump Causes It Not to Start

The fuel pump is active to get fuel to the carburetor. 

A pump will be required to help move the gas when the fuel tank is located below the carburetor. A fuel pump, just like any other computerized part, can go wrong over time. A likely reason is due to old fuel eroding the pump components.

7. Clogged Fuel Filter Causes a Cub Cadet Not to Start

Your fuel filter is a line of defense to prevent dirt and debris from entering the engine by straining the fuel. 

Be sure, though, that the fuel that is going on into the filter is also going out of the filter. 

If it does not, you must change it because it is most probably clogged, deterring your Cub Cadet from starting.

8. Clogged Fuel Line Causes a Cub Cadet Not to Start

Old fuel and dirt leave residues that can plug up your Cub Cadet mower’s fuel line.

9. Clogged & Dirty Carburetor Causes a Cub Cadet Not to Start

The purpose of the carburetor is to rectify the right amount of gas with the proper amount of air so your engine can generate combustion. 

Carburetors can get crusty buildup and gummy residues from utilizing old fuel containing ethanol.

10. Bad Battery or Loose Terminals on Your Cub Cadet Causes It Not to Start

Your Cub Cadet lawn mower needs a charged battery in order to turn it on. 

If your cables occur to be loose or your battery terminals indicate hints of corrosion, they can result in your mower starting problems.

11. Bad Safety Switch on Your Cub Cadet Causes It Not to Start

Your lawn mower may use numerous safety switches in its operator’s presence control system. The buttons are constructed to stop the engine when the operator gets out of the seat.

A bad switch may not comprehend when the operator is in or out of the seat resulting in your mower not starting.

12. Bad Cub Cadet Ignition Switch Prevents Mower from Starting

You put the key into your ignition switch and twist it, only to discover that nothing happens. 

Your Cub Cadet mower does not turn on. The ignition switch can be the reason. You can utilize a multimeter to assess the ignition switch.
