Locating your riding lawn mower's air filter is a straightforward process. It's usually found on top of the engine, under a large cover that you'll need to open. For most riding mowers, the air filter housing is larger and more visible than on push mowers.

To access the air filter, you'll need to remove the cover, which is typically held in place by clips, screws, or a latch. Some mowers may have a large thumb screw that you can remove by hand. It's a good idea to consult your owner's manual for specific instructions, but most air boxes are not pressurized and don't need to contain liquid, so they're not screwed together too tightly.

Here are the common locations of the air filter housing on riding lawn mowers:

  • Top of the engine, under a large cover
  • Under the engine cover

Remember to take a picture or note how the filter is positioned before removing it, so you can put it back in the same direction.

Types of Mower and Filters

Riding lawn mowers come in different types, and each has its own air filter needs. Most gas-powered models have air filters, which are often inexpensive and easy to maintain.

Types of Mower

There are three main types of lawn mowers: gas-powered, electric, and manual. Gas-powered mowers, which are the most common type, require regular maintenance to keep them running smoothly.

Not all gas-powered mowers are created equal, but most have air filters that help keep the engine running clean. In fact, most modern push mowers and riding mowers have paper air filters.

Paper air filters are made of pleated paper inside a plastic or rubber frame, similar to a car air filter. They're usually white or yellowish when new and should be replaced every 25 hours of use or once per mowing season.

Here's a quick summary of the three types of mower air filters:

Dual Element

Dual Element filters are a type of air filter used in high-performance mowers and some riding mowers. They consist of a combination of a paper filter with a foam pre-filter wrapped around it, which helps block larger debris before it reaches the paper filter.

The foam pre-filter can be cleaned and reused until it tears or no longer returns to its original shape after being squeezed. However, the paper element must be replaced if it gets too dirty. This setup allows you to clean the pre-filter with soap and water, which can help extend the life of the paper filter.

The filter housing is usually held together with big thumb screws that you can remove by hand. Some have metal spring clips holding the air box together.

Here are some methods to clean the filter housing:

  • Use a dry cloth to wipe away dirt and debris.
  • Use your air compressor and spray nozzle to blast dirt and debris from the inside of the filter housing.
  • Use a dry rag or a small brush to clean out any dust, grass, or grime inside the housing.

Installing a new or cleaned air filter is a crucial step in keeping your riding lawn mower running smoothly. Check the filter to see if any arrows guide you with the proper placement.

Amanda's owner's manual suggests cleaning the paper air filter every 25 hours and replacing it after 150 hours. You can refer to the photo you snapped with your phone for the original placement if you're unsure.

If your air filter is beyond saving, throw it out and install a new one of the same type. Check your mower's manual or do a Google search to find filters compatible with your machine.

To clean or replace the air filter, follow these steps:

  • If your filter still looks like it has some life left, tap it gently against the nearest hard surface to knock loose as much dirt as you can.
  • If it's a foam filter, gently wash it in warm, soapy water, then set it somewhere warm to dry.
  • If you've got a paper filter, stuff a clean shop rag into the center to keep dirt out, then blow off the outside with the air compressor, getting all surfaces as clean as possible.
  • With the outside of your paper filter clean, remove the shop rag, then insert your air spray nozzle inside and blow out the filter from the inside out.
  • If your paper cartridge filter has a removable outer wire mesh or foam sleeve, take it off and clean it separately.

Insert the new or cleaned filter into the housing, ensuring it's in the correct orientation to fit snugly. For a dual-element filter, start by placing the foam pre-filter over the paper filter, then insert them as a single unit into the housing.

Understanding Your Mower

Your lawn mower's air filter is a crucial part that needs regular cleaning to ensure your mower runs smoothly.

The location of your lawn mower's air filter will depend on the type of mower you have, but it's usually found on the carb side of the engine.

On a small, walk-behind lawn mower, the air filter may be a small piece of paper located on the carb and under the engine cover.

Larger mowers often have a larger foam or air filter under a cover, on top of the carburetor.

Other mowers have a large air box plumbed to the carburetor with a filter inside.

If you can't find your filter location in your lawn mower's owner's manual, try locating the carburetor feeding gasoline to your engine, and look for your air filter nearby.

Removing the air filter cover or the top of the air filter box is usually the first step to accessing your lawn mower's air filter.

Many air boxes are held together with big thumb screws that can be removed by hand, while others have metal spring clips.

The air box is not pressurized and doesn't contain liquid, so it's not screwed together tightly.
