How to Change the Air Filter on a Cub Cadet Riding Lawn Mower
To ensure that your engine runs smoothly this season and the next, regularly clean or replace the air filter on your Cub Cadet riding lawn mower. It’s recommended that your air filter be cleaned or replaced every 50 hours of use. In dry, dusty conditions this should be done more frequently.

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

Begin by parking your mower on a flat, level surface. Turn the engine off and allow it to cool, remove the ignition key, disconnect the spark plug ignition wire to prevent accidental starting, and engage the parking brake.

Use a rag to clean the engine of dirt and debris. Remove the air filter cover and the air filter.

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

Wash the foam pre filter. Use mild detergent and warm water to wash the foam pre filter and allow it to dry completely. Keep in mind – never use gasoline or low flash-point solvents for cleaning the air filter elements.

Place the dry pre filter back onto the air filter and reinstall the air filter. Secure the air filter cover and lock handles.

Reconnect the spark plug ignition wires on your Cub Cadet riding lawn mower.
