The horror stories about pressure cookers and toasters exploding have become commonplace, but how about lawnmowers?
In most cases, explosions in lawn mowers occur when combustible gases build up in the engine. The engine’s spark plug ignites these gases. This results in an explosion.
There aren’t a lot of explosions, but they can be dangerous. If you use a lawn mower, be aware of the risks and take steps to avoid them. Read on to learn can a lawn mower explode. What is the reason, and how to prevent it?
Can Lawn Mowers Explode?
Yes. A lawn mower can explode for several reasons, including fuel leakage, spark plug problems, or carburetor issues. A malfunctioning engine can cause a loud noise, smoke, and even a hole in the side. In normal operation, there is very little risk of exploding, but regular maintenance can reduce it.
What Can Cause a Lawn Mower to Explode?
The most common reasons why a lawn mower explodes or increases the risk are:
1. Fuel leakage
Fuel leakage is one of the most common causes of lawn mower explosions. This can happen due to a broken seal or a cracked tank. The gas can seep into the engine and cause an explosion.
2. Spark plug problems
A lawn mower’s spark plugs are responsible for igniting the gas in the engine. If they’re not functioning properly, sparks might not reach the combustible gases, and an explosion can occur.
Symptoms of a broken spark plug include sparking when you start your lawn mower, no sparks when you try to start it, or black smoke from the engine.
3. Carburetor problems
The carburetor is responsible for mixing air with fuel and sending it to the engine. If it’s not working correctly, gas can leak out of the tank and into the engine. It can cause the lawn mower to overheat and explode.
4. Fuel contamination
If the fuel is contaminated with dirt or other material, it can create an explosive mixture when it’s lit. It’s important to ensure that your fuel is of the highest quality and free of contaminants.
5. Grass clippings
The most common cause of lawn mower exploding is overzealous grass clipping. You’re putting yourself and your lawnmower at risk by clipping too close to the ground. Instead, try to clip just below the surface of the grass to avoid any potential damage.
6. Engine failure
In some cases, engine failure may cause an exploding lawn mower. This can happen if there’s something wrong with the engine block, pistons, or valves. If you notice any unusual noises or problems with your lawn mower, it’s important to check it out as soon as possible.
7. Overloading the engine
Overloading a lawn mower can cause it to overheat and explode. Be sure to adjust the blade speed and torque appropriately, and never overload the engine with more than its rated capacity.
8. Unwarranted changes to your lawnmower
If you make any changes to your lawnmower that the manufacturer did not approve, these changes may cause it to overheat and explode. These changes could include changing the belt, adding accessories, or replacing the engine.
9. Faulty electrical systems
Faulty electrical systems on the lawn mower can increase the risk of exploding. Check all wiring for signs of damage or corrosion, and replace any cables or connectors that appear to be faulty.
10. Not cleaning the deck
Another common mistake is neglecting to clean your lawn mower deck. This can lead to a build-up of debris and oils, which can cause a lawnmower to explode. Make sure to clean your mower’s deck at least once a month to prevent any potential accidents.
11. Metal blades striking rock
Metal blades striking rock can also cause a lawnmower to explode. By hitting small pieces of metal while cutting grass, you’re increasing the chances of an accident happening and your machine blowing up in your face (or on the ground).
If this happens to you, don’t panic – just take your machine in for servicing as soon as possible so that the issue can be fixed and avoided in the future.
12. Operating the mower during extreme weather conditions
Beware of extreme weather conditions like lightning storms and very windy rain or snow – these conditions can cause the lawnmower to skid or slip, leading to accidents or even injury.
13. Poor maintenance
Poorly maintained lawnmowers are a common cause of lawnmower explosions. Make sure to keep the machine clean and free from debris, and regularly tighten all screws and bolts (especially those that hold components together).
14. Improperly storing the mower
If you don’t have enough room to store your lawnmower properly, it will become susceptible to moisture and pests. Keep it stored in a dry and cool area out of reach of children and pets.
How to Prevent a Lawn Mower from Exploding?
If you’re like most homeowners, you probably take your lawn mower pretty seriously. After all, it’s one of the most important tools in your arsenal – it helps you take care of your lawn quickly and easily.
However, you can do a few things to ensure that your lawn mower stays safe and doesn’t explode on you. Here are the best tips from experts:
1. Follow the manufacturer’s instructions
Make sure to read the manufacturer’s instructions thoroughly before using your lawn mower. This way, you’ll know how to properly fill the gas tank, tune the engine, and more.
2. Have a functioning safety system
Make sure your lawn mower has a functioning safety system that includes an emergency stop button, spark arrestor, and blade guard. These systems help prevent accidents and injuries in case of an exploding machine.
3. Have the correct tool for the job
Make sure you have the right lawn mower for the type of grass you’re cutting. If you’re using a gas-powered lawn mower, make sure it has a spark plug and air filter. If you’re using an electric lawn mower, ensure it has a ground fault circuit interrupter (GFCI) and a voltage regulator.
4. Check the oil level
Make sure the oil level is at the correct level, and check it often. Over time, oil can become contaminated with acid and metal particles, which can cause a lawn mower to explode.
5. Use the correct fuel
Make sure to use the right fuel for your lawn mower – gasoline, diesel, or ethanol-ethanol blends – and avoid using low-quality fuel that may contain lead or other harmful chemicals.
6. Be careful with the exhaust
Make sure the exhaust is properly installed and functioning. A clogged or malfunctioning exhaust system can cause your lawn mower to overheat and potentially explode. Check the exhaust system regularly and repair or replace any clogged or defective parts.
7. Inspect the blades regularly
Keep an eye on your lawn mower’s blades regularly to ensure they’re in good condition. If they start to wear down or look rusty, have them replaced as soon as possible.
8. Clean and regularly lubricate
Make sure to clean and lubricate your lawnmower regularly using a quality product. This will keep it running smoothly and prevent any problems from occurring down the road.
9. Keep the lawn mower clean
A clean lawn machine is a safe lawn machine. Cleaning it regularly will prevent debris and oil buildup, which can increase engine noise and wear and tear.
10. Do not mow in the hot sun
There are a few ways to prevent your lawn mower from exploding, and one of the top tips is to avoid mowing in the hot sun. Lawnmowers are designed to run at high speed, and when they’re exposed to the sun’s heat, the blades can heat up quickly and start making sparks. This can lead to an explosion, which is definitely not something you want happening in your backyard!
11. Mow slower than usual
Another common cause of lawnmower explosions is mowing too fast. Try to mow at a slower pace so that the engine has enough time to cool down. This will help avoid any potential fires or explosions.
12. Avoid mowing if the grass is wet
Wet grass can cause lawnmowers to overheat, leading to an explosion. Try to avoid mowing when the grass is wet at all costs, especially if it’s been raining recently.
13. Maintain proper equipment maintenance
Regularly check your belt, spark plugs, clean dirty air filters, and more for wear and tear, and replace them as needed. This will help ensure that your lawn mower operates at its best and doesn’t experience any unexpected malfunctions.
14. Store properly
Store your lawnmower in a safe place where children and pets cannot access it. This will help keep it safe from damage and ensure that it doesn’t explode on you at a later time.
15. Repair your mower if it’s broken
Mowers that are not properly repaired can overheat and eventually explode. Make sure to replace any worn-out or broken parts, and keep your lawn mower in good working condition to avoid any potential accidents.
Can a Lawn Mower Catch on Fire?
Yes, lawnmowers can catch on fire, especially if they’re not maintained properly. If your lawn mower starts smoking or has flames coming out of the engine, stop using it immediately and contact a professional to fix it.
The leading causes of lawn mower catch fires are listed below:
1. Fuel hazards – One of the most common causes of lawn mower fires is using the wrong type of fuel. Make sure to use a fuel that is compatible with your lawn mower’s engine. Make sure to follow the manufacturer’s guidelines for fuel usage, and NEVER fill your mower up completely to the top – always leave a little room to spare.
2. A gas cap leak or sloppy fueling – Leaks in the gas cap or improper fuel injection can cause a lawn mower to catch fire. For example, if dirt and grass mix with the gasoline, a leak will occur, and gasoline will seep into the engine.
3. Short circuit – A short circuit board can also cause a lawn mower to catch fire. For example, if there is a problem with the spark plug, the lawn mower’s electrical system may not be able to ignite the gas properly.
4. Dry leaves or grass gets stuck in the mower deck – If your lawn mower has a mulching or clippings mode, make sure to empty the bag or container after each use. This will prevent grass from getting stuck in the blades and leading to a fire.
