Mowers for lawns are typically long-lasting, dependable machinery. But don’t assume the mower is doing its job well just because it’s turning over. This is rarely the case. If you want your mower to last as long as possible without breaking down, you need to perform routine maintenance twice a year, once in the spring before you use it and once in the fall before you put it away for the winter.
In this blog, we will discuss the significance of routine maintenance and show you how to clean the air filter on your lawn mower.
We’ll also go over why it’s so important to change your lawnmower’s air filter every year and why anyone can and should try doing it themselves to save money and keep their mower running smoothly.
Why Is Your Lawnmower’s Air Filter Important?
When it comes to the day-to-day functionality of your lawn mower, the air filter is one of the most essential components you need to pay attention to.
If your mower kicks on but doesn’t cut grass smoothly or seems to get stuck frequently, the air filter is likely to blame.
Taking in the air is crucial because combustion engines can’t work without it. If dirt and debris are sucked into the engine simultaneously with the air, complications will arise. You may have problems if this occurs, such as the mower not starting.
Grass clippings, sticks, twigs, leaves, dust, and dirt can all cause engine damage, but air filters keep them out while letting air into your engine.
However, over time, all air filters get dirty or blocked (which means they’re working). Clogged and dirty ones reduce the air reaching the engine, leading to malfunction. That’s why it’s crucial to keep the air filter clean on your mower.
The air filter will be easy to spot, and it could be on the side or top of the engine, depending on your mower type. The filter is easily accessible in all models, although a plastic cover may hide it.
In most cases, it is secured in position by a single screw-on or snap-on cover for the hinge.
Signs Of A Dirty Air Filter
Knowing when to change your air filter is important to keeping your lawn mower running smoothly. Common indicators of a clogged air filter include:
Engine Power Has Been Reduced
Reduced efficiency and performance can result from a dirty air filter preventing fresh air from reaching the engine. Your lawn mower may not be able to cut the grass as easily as it used to, or it may have less power.
Excessive Use Of Fuel
The proper air-fuel ratio for combustion can be thrown off if the air filter is dirty. An increase in fuel consumption is possible if the engine needs to burn more fuel to make up for the decreased airflow. It’s possible that a dirty air filter is to blame for your lawnmower’s increased fuel consumption.
Starting The Engine Is Difficult
It might be easier to start the engine if the air filter is clogged with dirt and other particles of debris. It’s possible that you’ll have to pull the starter cord more than once, or there will be a delay before the engine starts.
Exhaust Odour Or Black Smoke
Incomplete combustion can occur when a filthy air filter does not efficiently catch particles. This may result in exhaust smelling strongly of exhaust or emitting black smoke. These symptoms indicate that the air filter needs to be cleaned or replaced.
Types Of Lawn Mower Air Filters
It is important to know what kind of air filter your lawnmower uses so that you can clean and service it correctly, as lawnmowers use a wide variety of air filter types and designs. Mowers typically have one of two things:
Following this, you will find information regarding each variety of air filter that is typically utilised in mowers.
Paper Air Filter
A paper filter resembles an accordion made of paper. Perforated paper with very small holes is used in a folded design to achieve this effect.
Tiny holes allow air to flow through but keep out dust and other particles. Paper filters can be cleaned, but they still need to be replaced every 25-50 hours of mowing.
The paper air filter for the self-propelled mower can be found on the side of the mower’s engine, underneath a rectangular plastic cap that is pressure-mounted and simple to remove. This cap is located on the side of the mower.
Because the filter inside is only held in place by the housing, we remove it before each use, give it a light shake to loosen any debris, and then blow air across the paper fins.
Most hardware stores and home improvement centres will carry the appropriate replacement paper lawnmower filter for around $8.
Combination Filter
The best air filters for mowers are combination filters because they use foam and paper elements to trap debris and keep the engine running smoothly.
The foam provides a protective layer before the paper is added, which makes the paper more resilient (which has a higher replacement cost).
When it finally reaches the engine, the air has been significantly purified as a result of having gone through two layers of filtration.
Foam Filter
Foam-only filters are functionally equivalent to paper filters but use foam rather than paper as the filtration medium. Foam covered in motor oil is an excellent dust and dirt collector.
The motor oil serves a crucial function in the setup by trapping even the tiniest dust and debris particles. When no motor oil is present, the foam filter can only catch the largest particles, leading to a clogged carburettor that will require servicing.
Mowers with foam air filters require regular re-oiling after 25 hours of use or every three months.
How Often Should A Lawn Mower Air Filter Be Cleaned?
Keeping the air filter clean or replaced can do wonders for your lawn mower’s performance and lifespan. After every 25 hours of use, you should clean the foam pre-cleaner. Every season or 300 operating hours, replace the paper air filter. It may be required to clean and replace filters more frequently in dusty environments.
Steps To Clean An Air Filter On A Lawn Mower
Mowers are essential to keeping a lawn looking neat and healthy. Keeping your lawnmower’s air filter clean will prolong its life and help it perform at its best. The engine’s performance can suffer, and fuel consumption can rise if the air filter is dirty. To keep your lawnmower running smoothly, we’ve laid out detailed instructions for removing and replacing the air filter.
What You’ll Need
Equipment / Tools
- Safety gloves
- Washing bin, sink, or garden hose
- Paper towels, rags, or other clean, dry materials
Materials
- filter replacement (if necessary)
- 1-2 teaspoons of motor oil for a foam filter
- liquid dishwashing soap
Step 1: Stop The Mower
Put a stop to the engine of the mower. Before handling, make sure that all moving parts have completely stopped and cooled down.
Step 2: Remove The Spark Plug
Before removing the cover from the air filter, you need first to disconnect the wire from the spark plug.
Step 3: Remove The Air Filter’s Shroud
To access the air filter on a lawnmower, you’ll need to detach the screws or undo the clips that hold the protective shroud in place.
The air filter on a lawnmower is protected from debris by a metal or plastic shroud, which is fastened in place with a screw or snaps.
Step 4: Remove The Air Filter
Take out the air filter so it can be inspected.
Tap a paper filter on a flat surface to remove excess dust and debris. Hold the filter up to a light to take a look at it. If the filter’s paper element obstructs a lot of light, replace it rather than try to clean it further. Just get a new one and put it in its place.
Foam air filters need to be replaced when they begin to crumble or show telltale brown or yellow staining. If it’s in good enough shape to be cleaned, go ahead.
If your hybrid vehicle has a special air filter, it should be cleaned or replaced according to the manufacturer’s guidelines. The foam pre-cleaner on a hybrid vehicle needs to be checked regularly. Replacement of the foam pre-cleaner is typically necessary if it has become rigid, brittle, or heavily stained.
Step 5: Get The Foam Filter Clean
To remove grime and restore the filter’s efficiency, rinse the foam filter under water from a garden hose or in a washing sink. Dish detergent can be used to get rid of grime and greasy buildup. Squeeze any remaining water from the soapy foam using cloths, paper towels, or your hands.
Step 6: Foam Filter Drying
First, the foam filter must be completely dried before it can be oiled. First, use paper towels or dry cloths to squeeze the foam out of the container. After that, leave the foam exposed to the sun for approximately one hour so that it can continue to dry.
Step 7: The Foam Filter Should Be Oiled
When the foam is completely dried, you can oil it. Massage the oil through the filter by putting it in your hands or directly onto the foam. Don’t overfill the oil reservoir, as this could cause leaks in the mower.
Step 8: Clean The Fitting Of The Air Filter
Air filter housings should be cleaned with a dry cloth before being reinstalled. Do not use any solvent, as this will ruin the air filter element. Also, you shouldn’t use compressed air because it could send debris crashing into the lawnmower’s carburettor.
Step 9: Reinsert The Air Filter
Put the air filter back into the fitting where it belongs. Check to see that it fits properly and that there are no gaps.
Step 10: Change The Shroud
When reattaching the protective shroud, you need to be careful not to pinch the air filter element or cause any other kind of damage to it.
Step 11: Connect The Spark Plug Again
Remember to reattach the wire to the spark plug before attempting to start the lawn mower.
How To Change The Lawn Mower Air Filter
Changing the air filter on a lawnmower is a quick and simple task.
Here are the steps.
- Find the lawnmower’s air filter housing. Where you put it depends on what kind of mower you have. To access the engine on a tractor mower, you’ll need to lift the cover; on a walk-behind mower, however, the engine is typically visible. Usually housed in plastic or metal, the air filter can be found on top, in front, or along the side of the motor.
- Depending on the type of mower you have, you will need to either unscrew the lid or open a hinge in order to access the housing.
- Check the foam pre-filter on your lawnmower by taking it out. It’s acceptable to clean the foam and re-oil it on occasion. However, new foam must be installed if the old one is stained, brittle, or hard.
- Now we’ll switch to the major filter. Tap the paper air filter to remove dust and debris. The filter needs to be changed if the paper becomes clogged. Hold the filter to some light or the sun to see if it works. Again, if your foam air filter is stained, hard, or otherwise damaged, it needs to be replaced.
- Get rid of the old filter for the air conditioner.
- After the housing for the filter has been cleaned, you can install the new filter.
- Replace any coverings you removed and secure the housing’s top. Always avoid pinching or tearing the new air filter as you install it. Large particles can get through the filter and into the engine if there are any holes.
Common Mistakes To Avoid While Cleaning The Air Filter
