You can blow up a lawn mower

Blowing up a lawn mower is a terrible thing. It’s dangerous, it’s loud and it can be incredibly messy. That said, if you’re going to blow up a lawn mower (and maybe you will) then it’s best to know the facts:

Lawn mowers have air filters that filter out dust and debris from being sucked into the engine, but this doesn’t always work. If there are large pieces of debris, they could get stuck in the engine or cause serious damage when things start moving faster than planned.

When a lawn mower runs for too long without oil (or enough oil), this also causes problems with parts wearing out more quickly than they should be able to last before needing replacement parts like new blades or belts. 

This means that if you keep running your machine without adequate lubrication levels in place during operation time frames, then certain subsystems within would wear down faster than expected during normal operations due to lack of sufficient lubrication levels needed within its working environment during prolonged periods as well instated earlier above under Section Topic Title 1 Section Topic Title 2 Section Topic Title 3 etcetera etcetera etcetera etcetera…

If you’ve noticed brown patches on your lawn, it might be a sign of a nutrient deficiency, pest problem, or disease. Before trying out any solutions, it’s important to identify the underlying issue. Learn more about identifying the cause of brown patches and how to address it in our guide.

Lawn mowers should be stored properly

Proper storage is key to keeping your lawn mower in good shape. If you don’t store your mower properly, it could become damaged and won’t work well when you try to use it again. Here’s how to do it:

Keep the machine dry. A wet lawn mower doesn’t start as easily, so make sure it’s stored in a space where there isn’t any moisture around (like under an overhang). 

In addition, if water does get inside of your machine and onto its engine parts, this will cause corrosion which can damage them permanently—and then you won’t be able to use the machine at all! So keep everything nice and dry by storing it in a cool place with no rain or snow falling on top of it

Check the oil

You should check your oil level before every use. If you don’t, you might end up doing damage to the engine. Oil is what keeps your lawn mower running smoothly and helps keep it cool. If the oil level is too low, then there could be some serious problems with your engine.

Poor drainage can cause flooding, erosion, and even damage to your home’s foundation. To avoid these problems, it’s important to have proper drainage in your backyard. Check out our easy fix for adding drainage to your yard and preventing water buildup.

Clean the air filter and/or carburetor

If you’ve been storing your lawn mower for winter, or if it’s just been sitting around for a while, it may have become clogged with dirt and debris. 

Pay attention to the air filter and carburetor, which are the two most common culprits of this problem. If either of these are dirty or clogged with debris, clean them out and replace any filters that need replacing.

If you’re still having trouble after doing this, check the fuel tank for water. Water in your gas will cause problems with engine performance as well as make an explosion more likely than it would be otherwise

Always use fresh fuel

Fuel with ethanol in it is preferable, as long as you know that your engine can handle it without problems. 

You should also avoid using fuel that has been sitting around for a long time or stored improperly, since these can cause corrosion and other issues that could make the machine stop working properly.

If you’re looking to create privacy in your backyard, there are a number of options available to you. From hedges to privacy screens, the choice depends on your personal preference and the layout of your yard. Learn more about adding privacy with our easy way guide.

Change the spark plug regularly

You probably know that the spark plug is the heart of your lawn mower’s engine. It ignites the fuel and is one of the most important parts because it ensures everything runs smoothly and safely. But did you know that you should also change it every year? This will keep your machine running at its best.

Here’s how to do this job:

Disconnect power from the mower by turning off its electrical switch or unplugging its power cord from an outlet. If you are unsure whether or not your model has an electric switch, look for a red button on top of the starter motor assembly (or inside) that connects directly with a wire leading to either side of this button; if more than one wire enters here, then disconnect all but one at once when shutting off power.

Don’t forget about the blades.

Don’t forget about the blades!

While you’re cleaning out your lawn mower and checking for leaks, don’t forget to check the blades. 

They can dull over time and need to be sharpened or replaced. Also, make sure the blade tension is set correctly so that it doesn’t fly off during operation. If you’re not sure how to adjust these settings on your lawn mower, consult a professional before trying anything yourself!

Adding shade to your backyard can make it a comfortable and enjoyable space for outdoor activities. One option for adding shade is to install a canopy or awning. Learn how to add shade to your backyard with our easy fix guide.

Maintain proper tire pressure

The first and most important thing you can do to avoid lawn mower explosions is to maintain proper tire pressure. 

If you drive your lawn mower on a regular basis, it’s a good idea to check the tire pressure at least once a week. You should check the tire pressure when the tires are cold (i.e., before you start your engine) and use a gauge that measures pounds per square inch (psi) if available.

As for how often you should check your tires’ air pressure:

  • Once every two months if you use it less than 2 hours per week
  • Once every month if you use it 4-8 hours per week

Tire care is important even when driving short distances because running over things like rocks or sharp sticks can cause small punctures in the rubber that don’t show up immediately but eventually lead to leaks as they get bigger over time

Tips for Maintaining Proper Tire Pressure on Your Lawn Mower

Check the pressure regularlyChecking your lawn mower’s tire pressure before each use can help prevent problems and prolong the life of your tires. Refer to the owner’s manual for the recommended tire pressure for your lawn mower.
Use a tire gaugeTo get a precise measurement of your tire pressure, use a tire gauge. This device can be purchased at most hardware or automotive stores.
Inflate or deflate as neededIf your tires are overinflated or underinflated, adjust them as needed to reach the recommended pressure. Be sure to use a tire pump that is designed for use with your lawn mower’s tires.
Avoid extreme temperaturesExtreme temperatures can cause changes in tire pressure. If possible, store your lawn mower in a temperature-controlled garage or shed to prevent problems with your tires.
Consider switching to solid tiresSolid tires can eliminate the need for tire maintenance, as they are not filled with air. However, they can be more expensive and may not be suitable for all types of lawn mowers.

Drain water from the fuel system when temperatures drop

If you’re not careful, the engine will rust from the inside out. If you live in a colder climate and drain water from your fuel system during winter months, you can greatly reduce the chances of such damage. Here are some additional tips to keep your lawn mower up and running:

  • Drain water from the fuel system when temperatures drop. If water freezes in the carburetor or other area, it may crack them, causing permanent damage to your mower’s components.
  • Avoid storing gasoline near heat sources or direct sunlight as this increases its volatility and can cause vapors to explode (which is why we don’t recommend using gas-powered candles).
  • Keep gasoline stored outdoors or in a well-ventilated space away from sparks and open flames (you know how kids love matches…).

Concrete is a versatile material that can be used for a variety of projects in your yard, from walkways to patios. If you’re looking to add concrete to your yard, learn how to do it with our easy way guide, which covers everything from preparing the ground to pouring the concrete.

Keep up with regular maintenance.

Maintaining your lawn mower is an essential part of keeping it in good condition. Following these steps can help to ensure that your equipment lasts for years to come:

  • Check oil level, air filter and spark plug. Replace as necessary.
  • Sharpen blades frequently with a file or stone to make sure they cut grass effectively without wearing down too quickly and making unsightly marks on the lawn.

Additionally, it’s important to keep up with regular maintenance like tune-ups, blade sharpening and air filter replacements throughout the season as well as annual inspections at least once per year between seasons to avoid unnecessary problems that could result in costly repairs down the road

Be careful when leaving your lawn mower outside

As previously mentioned, lawn mowers are not meant to be left outside. This is especially true in areas where there are extreme temperatures or the lawn mower will be exposed to harsh weather conditions. 

If you live in an area where it snows, make sure that your lawn mower is stored in a dry and covered area so that any snow won’t settle on it and cause damage when it melts.

If you do decide to leave your lawn mower outside for any reason (for example, if you live in an apartment), make sure that it’s somewhere where the elements won’t affect its functionality or cause any issues with rusting or other problems. 

It may also be helpful if you put some type of cover over the top of the machine so no rainwater gets into the engine area; this can cause serious damage over time!

Tips for Storing Your Lawn Mower Outdoors

Choose a sheltered locationWhen leaving your lawn mower outside, choose a location that is sheltered from the elements. This can help prevent damage to the mower and prolong its lifespan.
Cover the lawn mowerUsing a cover can help protect your lawn mower from moisture, sunlight, and other environmental factors that can cause damage over time. Make sure to choose a cover that fits your model of lawn mower.
Store gasoline safelyIf you store gasoline for your lawn mower outside, make sure to keep it in a container specifically designed for gasoline storage. Store the container in a cool, dry place away from heat sources.
Remove the batteryIf your lawn mower has a battery, remove it and store it indoors in a cool, dry place. This can help prolong the life of the battery and prevent any potential hazards.
Check for rodentsRodents can damage the wiring and other components of your lawn mower. Before storing it outside, inspect it for signs of rodent damage and repair any damage that you find.


All in all, you should be able to avoid blowing up your lawn mower if you take some basic precautions when using it. Use the right fuel, change the spark plug regularly and keep up with regular maintenance. Don’t forget about the blades (especially if they are sharp).

Finally, make sure that everything is clean and dry before starting up your lawn machine again after storing it over the winter months or letting it sit idle overnight due to bad weather conditions like rain storms or snow storms.
