Troubleshooting Tips for Cub Cadet Lawn Mowers

Troubleshooting Tips for Cub Cadet Lawn Mowers

If you want your Cub Cadet lawn mower to work effectively each time you start it, there are certain maintenance steps to take to ensure your machine is in great condition. Maximize the life of your mower with these troubleshooting tips.

Tip #1 – Keep up with routine maintenance

Stay on top of routine maintenance. This will increase the performance and life span of your Cub Cadet lawn mower. Your lawn mower is most likely the most frequently used piece of outdoor power equipment so perform the proper maintenance to maximize life and efficiency.

Tip #2 – Check spark plugs and carburetors

Clogged air filters, fouled spark plugs, and flooded carburetors are common problems that can affect the starting and performance of your Cub Cadet lawn mower.

Replacing the spark plug can make a huge difference in the performance of your mower. To combat a flooded carburetor, you need to drain the carburetor and put new fuel in it.

Tip #3 – Utilize new fuel and air filters

Fresh fuel and a clean air filter will help prevent lawn mower problems. Use fresh, mid-grade fuel with no higher than E10 Ethanol rating, stored in a clean, sealed container.

To clean your air filter, tap it to remove loose dirt and debris. Hold your filter to the light. If you see the light, the air filter is okay to use. If there is no light, replace the old air filter with a new one.

Tip #4 – Keep a sharp lawn mower blade

Look at the blade on your Cub Cadet lawn mower. Dull lawn mower blades trim grass unevenly and leave the tips of your grass torn and not cleanly sliced.

Tip #5 – Check bolts, wheels, cables and belts

Tighten all bolts on your Cub Cadet lawn mower and check to make sure that the wheels, cables and belts are not overly worn. This can cause problems when mowing.

How to Change the Air Filter on a Cub Cadet Lawn Mower

The longevity of your Cub Cadet lawn mower depends on the maintenance you provide. Changing the air filter regularly will keep dirt and debris out of the engine and keep your mower running efficiently.  We recommend changing or replacing the engine air filter every 50 operating hours. In dry, dusty conditions this should be done more frequently.

Before performing any maintenance on your lawn mower, refer to your owner’s manual for maintenance instructions and safety information. Maintenance instructions vary by model, so depending on your lawn mower model our instructions may vary slightly.

Before changing the air filter on your mower, disconnect the spark plug wire to prevent accidental starting. Clean the engine of your mower and remove any dirt and debris. Remove the air filter cover and remove the air filter from the housing.

Check and clean the air filter. Remove the foam pre filter. Check for any rips or damage to the air filter. Clean the paper element filter by tapping gently to remove any dust or debris. If the paper element is very dirty or damaged, replace it with a new one.

Wash the foam pre filter using mild detergent and warm water. Allow the pre filter to dry completely. Never use gasoline or low flash-point solvents for cleaning the air filter elements.

Reinstall the air filter and pre filter. Install the air filter cover and reconnect the spark plug ignition wire.

The air filter on your mower provides proper air induction into the engine and allows the engine to run a lot cleaner. If you have a plugged air filter, dirt can get sucked into the engine or the machine won’t run correctly or run too rich. It’s important to replace the air filter regularly to keep you machine up and running all season long.
