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.

Cub Cadet Engine Oil Maintenance

Of all the maintenance done to your Cub Cadet equipment, engine oil maintenance is the most important. Checking, changing and using the proper crankcase oil are extremely important to the life and performance of your machine. Failure to use the correct oil and keep it clean can affect engine life and reliability.

The most important scheduled oil change over the life of an engine is the first one. Most manufacturers recommend performing the oil change after the first 5-10 hours of use. This helps flush out small particles that accumulate naturally during the break-in period.

Refer to your Cub Cadet owner’s manuals for viscosity, grades and time intervals for oil changes. Different machines require different oil and it is important to pay special attention to those recommendations in small engines.

A small engine uses engine oil to help keep it cool in high temperatures, so pay attention to maintenance when operating in those conditions. Check the engine oil before each use, checking for both proper oil level and for color.

Be sure to use high-quality detergent oil that has the American Petroleum Institute (API) rating. When changing engine oil allow ample time for a complete drainage.

When engine oil is new, it has a golden amber color. Over time, heat and dirt particles cause the oil to darken. Combustion byproducts, contaminants, and oxidized lubricant build up to form sludge, which will cause the oil color to darken. Dark oil is a good indicator for an oil change.

Engine oil maintenance is not the only maintenance that keeps your Cub Cadet equipment in working condition.

Other important maintenance includes air filter maintenance, gasoline maintenance, and spark plug maintenance. If you want your Cub Cadet lawn mower, snow blower, and other outdoor power equipment to operate properly for years, stay on top of regular maintenance.
