How Long Should a Lawnmower Last? 10 Things You Should Know

Are you getting the most out of your lawnmower? We share our lawnmower maintenance and longevity expertise, providing practical tips and insights to help you maximize its lifespan.

How long should a lawnmower last:

The average lifespan of a lawnmower is 6-10 years for gas and 7-13 years for electric, depending on quality, usage, maintenance, and storage. Proper maintenance per manufacturer guidelines and regular cleaning and replacing parts like blades, filters, and spark plugs is vital.

Want your lawnmower to last longer? Our article provides a wealth of practical tips and insights on achieving this. Discover how regular cleaning and maintenance can add years to your lawnmower’s life.


Factors that Determine the Life Expectancy of a Lawnmower:

Factors that affect a lawnmower’s lifespan include the lawnmower’s quality, environmental conditions, amount of use, intensity of operation, and maintenance.

1. Lawnmower quality:

When shopping for a lawnmower, there are always cheaper options that can save some money. Good quality, durable machines from reliable manufacturers often cost more than products from less stable brands. A good quality mower is made of a more robust material and uses more vital components.

But it does not always mean the more expensive lawnmower will last longer. There are many examples where cheaper ones last as long. More expensive does not always mean better quality. For some, you pay for the brand and the marketing.

Try to balance quality and price and select the most suited mower to your requirements, even if it costs a bit more. We recommend you do proper research before making a decision. Comparing specs and prices always helps. It is good to check reviews or visit a knowledgeable dealer.

With over two decades of experience, I can confidently say that the average lifespan of a lawnmower is between 8 to 10 years. However, with proper maintenance and care, it can last up to 15 years or more. It’s all about how you treat your machine.

2. Environmental conditions:

If you use your mower in a more environmentally challenging location, it can significantly influence its lifespan. If you use it very close to the sea, the salt can make it rust much more quickly. If you live in a wetter area, it can also lead to more rust.

In general, storing your lawnmower outside is not a good idea. If it rains, your mower will get wet. If it is sunny, certain plastic parts can wear much more quickly. Storing your mower in a protected location will help to improve its life span.

3. Amount of use:

The amount of use is one of the vital factors that decide the life of a lawnmower. Most lawnmower manufacturers measure and rate their products’ lifespan in usage hours.

These usage hours can be converted into life expectancy in years based on the particular usage hours per week for different customers.

This means that the life expectancy of a specific lawnmower model in years would be smaller for users who use their mowers more frequently than users who use their mowers less regularly. Generally, the more you use your mower, the earlier it will end, keeping other factors constant.

4. The intensity of operation:

5. Maintenance:

The intensity of operation is also an essential variable in determining the life expectancy of a lawnmower. Lawnmowers regularly used to cut thick and long grass have to work harder than mowers that regularly cut short and less dense grass.

Another essential thing to remember is that you should use your mower for the application it is made for. If your lawnmower is smaller and has a lower horsepower rating, you should not use it for huge yards, especially with rough, uneven terrain.

When shopping for a lawnmower, pick the one best suited to your needs. In this regard, consult the manufacturer or people with adequate lawnmower knowledge. Its components’ lifespan does not define a lawnmower’s life overall.

– Understanding the Importance of Regular Maintenance

For example, when the spark plug on your mower is not working correctly, it doesn’t mean the whole mower is terrible. Small individual components can be repaired or replaced easily to keep the mower running smoothly.

This is why maintenance is essential to a machine’s life. If a lawnmower is not adequately maintained, its major components, such as the engine, will fail earlier than expected, and the mower will reach its end earlier.

– Consequences of Procrastinating on Maintenance

Maintenance is easy and inexpensive if done regularly. If you keep procrastinating on maintenance, several faults will add up and severely damage the mower or become more complex and costly to repair.

The manufacturer’s manuals usually contain information and guidelines about maintenance and how often servicing should be done. Follow these guidelines to increase the life span of your lawnmowers.

Other Important Factors that Affect a Lawnmower’s Life:

Besides the factors mentioned in the section above, several other variables affect life and performance. Let’s look into some such variables:

In my 20 years in the field, I’ve seen many lawnmowers fail prematurely. The most common reasons include lack of regular maintenance, improper storage, and using the wrong type of fuel or oil. It’s crucial to understand your machine and treat it right.

6. Fuel:

Lawnmowers with gas engines work best on the correct fuel type. Using gas suited to your mower’s engine is more important than you think. Try to avoid poor-quality gas. Better quality gas might cost more, but it will enhance your mower’s lifespan.

Regarding gas, there are some essential things to know:


Regulating authorities have implemented ethanol in gasoline to reduce its negative environmental impact. Ethanol is added to gasoline in relatively small ratios, but ethanol-blended fuel can damage various parts of your lawnmower, especially those made of plastic and rubber.

Most lawnmower providers recommend the use of E10 fuel. E10 gasoline has 10% ethanol. Ethanol-blended petrol with more than 10% ethanol is generally not recommended and must be avoided.

Storing gas:

You must never store your lawnmower with gas sitting in the tank for an extended period. Gas sitting in the tank for an extended period (generally more than 30 days) will go wrong because of evaporation and oxidation, producing a gummy substance accumulated at various locations in the fuel system.

A clogged fuel system is bad for engine health and needs to be cleaned. Ethanol-blended gas goes earlier. When storing the mower for more than 30 days, drain the gas and use fresh gas when you intend to use the mower again.

Stabilizer: Adding fuel stabilizers to gasoline is generally considered a good practice. A fuel stabilizer prevents the gas from going rancid. Lawnmower users should use the fuel stabilizer recommended by their manufacturer in the recommended quantity.

7. Oil:

Oil is the second most crucial variable that massively affects the life of a lawnmower. Many moving components inside the lawnmower engine require proper lubrication or will be severely damaged by friction.

Using the wrong oil or running the mower with too little oil can cause engine overheating, which is undesirable. You should use the right oil for your lawnmower. Most manufacturer manuals contain oil-related guidelines. Grades categorize engine oils based on their properties, such as viscosity.

– Choosing the Right Oil Grade for Your Engine

Use the oil grade most suited to your engine. Secondly, you should ensure that your engine oil is clean and of good quality. You should check and change the oil regularly. If your mower is older, it will start to use more oil.

Try to check the level before each mowing session. Another essential thing to maintain is the greasing of external moving parts. Lawnmowers should be regularly greased to avoid wear and tear.

8. Battery and Spark Plug:

Using the correct battery with the proper voltage and charge is also very important. The battery contacts must be kept clean. Owners of electric lawnmowers are advised to charge the battery a few times in the winter when the mower is stored or use a trickle charger.

This will increase the life span of the battery. Using the correct spark plug is necessary. The spark plug specs should match the criteria recommended by the manufacturer. It would help if you regularly check and clean the spark plug.

Also, the spark plug lead should be kept clean. If a spark plug becomes so bad that it can’t be cleaned or repaired anymore, replace it. Most experts recommend lawnmower spark plugs be changed every 100 hours of use.

One thing I’ve noticed over the years is that people often make mistakes that shorten the lifespan of their lawnmower. These include not cleaning the mower after use, regularly changing the oil, and using dull blades. Avoiding these mistakes can greatly extend the life of your mower.

9. Fuel System and Filters:

Among other components, you should regularly service the fuel system. A clean fuel system is crucial for engine health and performance. Fuel lines, fuel filters, fuel tanks, carburetors, and other fuel system components should be regularly checked, cleaned, or replaced when necessary.

10. Blades:

Lawnmower blades lose their health over time. Users should regularly sharpen them for optimal cutting results.

When blades are sharpened several times and become too thin ch, dipped, or dented, they should be replaced. Ensure that the blade is well-balanced after pointing. If not, it can increase some lawnmower components’ wear and tear.

Gas Mowers vs. Electric Mowers:

The lifespan of gas mowers is generally shorter than that of electric mowers. On average, an electric lawnmower can last for 7-13 years based on the level of care, whereas a gas mower lasts for 6-10 years on average.

However, an electric lawnmower battery will probably need to be replaced one or more times over the mower’s life span. The life of the battery depends heavily on the number of times it is charged.

The more times it is charged, the less energy it can store. This means you can cut less than before and have to recharge it even more often.

Frequently Asked Questions:

• How can I extend my lawnmower battery life?

Fully charge batteries a few times during winter storage. Use a trickle charger if storing for months. Avoid excessive charging cycles by fully charging each time before mowing.

• Is maintenance worth the cost?

Regular maintenance significantly extends the lawnmower’s lifespan and avoids more costly repairs. Follow all manufacturer guidelines for optimal longevity.


The lifespans of different mowers, such as residential lawnmowers or commercial mowers, can differ significantly depending on many factors. Good quality mowers are usually expensive, so you would expect a costly mower to last long as the essential parts are well-maintained.

But the price is not the only factor at play. The size of your lawn and the usage and care given to the mower also heavily affect its life. For instance, a commercial mower used for extensive gardens may have a lifespan of 500 hours or more.

While a residential mower used for a small garden might last fewer hours, the battery life also influences how long my lawn mower will prevail. As for any machine, the way you use it also heavily affects its life.

• Importance of Regular Lawnmower Maintenance

So, if you want to enjoy your lawnmower longer, you should take good care of it and provide proper maintenance. This includes sharpening your blades at least once a week during the growing season, ensuring the mower is stored correctly when not used, and scheduling a repair when necessary.

So, is it worth investing in a high-quality mower? Considering the size of the Garden and the frequency of use, it might be worth a higher initial investment to ensure your lawn mower lasts longer.

After all, a well-maintained mower can serve you for many years, making it a worthwhile investment for the upkeep of your lawn.
