1. Lawnmower lifespan: Brand and Quality

There are many different brands and models of lawnmowers, including commercial mowers. Some brands are focusing mainly on price and have models that use cheaper engine parts.

Other brands include a model line with cheaper models and a model line with more professional models that are more expensive but will last longer. Generally, the more expensive models will last longer, but this is not always the case.

Choosing a lawnmower that fits your needs and maintenance programs is essential to get the best value. A well-maintained, average-sized lawnmower from an esteemed company can last 8 to 10 years of service. If unmaintained, it will only last half as long.

Why Measure in Working Hours, Not Years

However, years as a unit is ineffective when measuring a lawnmower’s life. A better unit is the number of working hours as it considers factors like usage. So, a small-sized lawnmower from a random company can last up to 300 hours.

And a pricier mower, larger in size, can give a service life of up to 500 hours from a better company. So, they vary from size to size and brand to brand. But is it worth a repair when it breaks down? How long do lawnmowers last? These are questions worth considering when purchasing a lawnmower.

2. Lawnmower lifespan and engine size:

Gas-powered lawnmowers are fundamentally as powerful as the engine capacity, the number of cylinders, or fuel type. They can vary from a small-sized single-cylinder piston engine to a comparatively larger twin-cylinder piston engine (riding lawnmowers).

A single-cylinder lawnmower engine can last 500-750 hours. A larger engine usually lasts longer, up to 1000 hours. These numbers are very rough estimates and only apply to the recommended maintenance. Remember that this hour rating is related to the engine’s life converted from the cycles run per life.

In my 20 years of experience, I’ve seen that the lifespan of a lawnmower engine is greatly influenced by factors such as maintenance quality, usage frequency, and fuel type

When it comes to the lawnmower, its life may vary as there are many other parts and factors to consider. How long do lawnmowers last is a question often asked by homeowners.

The answer to how long lawnmowers last depends on several factors, including the type of mower, the quality of its parts, and how well it’s maintained.

• Importance of Regular Maintenance

For at-home maintenance, it’s essential to regularly check and replace the spark plugs on your lawnmower and perform other routine repairs and maintenance tasks. This can help extend the life of your lawnmower and ensure it runs efficiently.

If you’re unsure how to maintain your lawnmower, don’t hesitate to contact a professional or consult online resources. Many solutions, both in-store and online, can provide guidance and supplies for lawnmower maintenance.

Finally, remember that every lawnmower is different. The lifespan of your lawnmower will be based on its specific make and model, as well as how well it’s cared for.

By taking the time to maintain your lawnmower correctly, you can help ensure it has a long and productive life, giving your lawn the edge it needs to look its best.

3. Lawnmower lifespan and usage:

The usage of your lawnmower can have a significant impact on the engine lifespan. For example, a small lawnmower may reduce its engine life to a mere 500-550 hours instead of 650-750 hours when used on a lawn with thick grass and twigs that it can barely cope with.

This is due to the extra load on the engine. In contrast, the same situation will not significantly affect a powerful lawnmower.

Similarly, when put in an industrial environment like the vast gardens of some universities, a lawnmower suiter for domestic use may not last as long as the predicted life prescribed on its box.

• Understanding the Impact of Usage on Lifespan

Another factor that influences the lifespan is the type of usage. Many short bursts significantly impact the engine more than longer, less frequent mower sessions. This mainly concerns a cold engine with more wear and tear than a warm engine, similar to a car.

The last case we want to mention is the terrain. A lawn with steep inclines will strain the engine more than a flat area, impacting the engine wear and tear. The more power your lawnmower has, the less impact the terrain will have.

4. Lawnmower lifespan and maintenance:

It is a well-known fact that maintenance and service are crucial to the life of any machine. The same is the case for the engine of a lawnmower. The engine is an amalgamation of different parts with their durations, after which they need to be replaced or serviced.

For example, you should change your lawnmower’s oil after every 50 hours of usage and sharpen your lawnmower blades after every 25 hours of use. For a riding lawnmower, the oil change duration increases to 100 hours due to its larger engine.

Similarly, the engine should be serviced every 48-50 hours or annually, whichever comes first. The air filter and spark plug should also get proper maintenance annually, together with the oil change.

If the lawnmower is given its due maintenance and its service requirements are fulfilled, it will work efficiently for its rated life at the very least.

How to increase the number of hours that a lawnmower will last:

You can increase the lifespan of your lawnmower by looking at the following:

  1. Change the oil regularly.
  2. Clean the air filter regularly.
  3. Regular usage.
  4. Sharpening the blades.
  5. Maintained belts.
  6. Efficient spark plug.
  7. Proper battery maintenance.
  8. Suitable environment.
  9. Proper and sharpened cutters.

 1. The Oil Changing of Lawn Mower

Change the oil regularly. The owner’s manual will give you the exact timing for your model. Most brands and models should be done after around 50 hours or annually (what comes earlier).

It is good to check the oil quality by regularly looking at its color and changing it when needed.

“From my experience, regular oil changes, cleaning or replacing the air filter, and using clean, high-quality fuel are maintenance practices that can significantly extend the life of a lawnmower engine.

2. Cleaning the Air Filter

Check and clean the air filter regularly. Combining it with changing the oil in your lawnmower is an excellent idea. When you often mow in a dusty environment, it can be wise to check it more often. When you store the lawnmower after the end of the season, clean it thoroughly.

3. Run the Engine Full Throttle at The End of Season

A device is as efficient as its owner, so let the lawnmower engine run wide open unless it goes out of fuel. This will help release the extra carbonated gas and related issues, and try it immediately at the season’s end. This will clean the internal engine of the lawnmower and work as an end-of-season cleaning.

4. Sharpen the Blade

Do sharpen the lawnmower’s blades regularly. An unsharpened blade could slow the lawnmower down, damage the grass, and unnecessarily strain the engine. Dull blades also made the grass turn brown instead of fresh and green.

5. Check the Belts

Be concerned with the driver’s belts while riding every time you use them. This is one of the essential parts for marinating the active lawnmower engine, which helps the lawnmower’s life expectancy.

6. Clean or Change the Spark Plug

Do check and clean the spark plug. Depending on your usage, expect to clean or change your lawnmower spark plug after five to seven months. If you use your lawnmower more than average, it can be necessary to clean or change it earlier.

7. Check the Battery of Lawn Mower

If your lawnmower has a battery, check it regularly. A good battery makes the lawnmower start better and makes the starter motor last longer. In the winter, try to keep it on a battery maintainer.

8. Free Yard from Wreckage

Before you start the mowing, check that the yard should be free from hard materials such as rocks, sticks, or wreckage. Do cleaning of the gathered dried grass from the underside of the deck and utilize a splash oil to keep it from building up once more

If there’s one piece of advice I’d give someone to maximize their lawnmower engine’s lifespan, it’s this: Regular maintenance is key. Don’t wait until there’s a problem to check on your engine.

9. Maintain the Cutter to Make Your Lawn Mower Last

Do the fixing, cleaning, and lubrication on the cutter with anything needed because it is essential to maintain the lawnmower’s cutter. The excellent cutter will appropriately tear the grass. Moreover, if one follows all these steps, the lawn mower will last longer and more than expected.

Frequently Asked Questions:

1. Should a lawnmower last more than five years?

Yes, a lawnmower should typically last more than five years if it is of good quality and you take good care of it. A well-maintained lawnmower could last for 10 years or more.

2. How many years should a small lawnmower last?

Small-size lawn mowers can be the right choice for smaller lawns as they are easy to maintain and economical. With proper maintenance, the estimated lifetime of a small lawnmower is at least 6 to 7 years.

3. Can I buy the eight-year used lawnmower, or should I always buy the new one?

One can also buy a used lawn mower because the excellent quality brand new lawnmower is quite expensive, so if you could have an opportunity to get a used lawnmower at a low price but in good or even average quality, go for it.

Sometimes, the lawn mores still work appropriately after the estimated and average time, but before buying the used lawn mower, it does have a test ride so that you can check its speed and check its blades. After all, the lawn mower’s blades are essential if they are not working satisfactorily.

The lawnmower is useless because dull blades could damage our grass and make it brown.


Moreover, an excellent manufacturing company’s lawnmower engine will last about 750-1000 hours, and the ordinary company’s lawnmower will last for 300-500 hours only because it does not have the same capabilities. Further, the maintenance of the machine also determines its service life.

For instance, the low oil levels and dirty filters could critically affect the engine and may not last 300 hours. Moreover, a lawnmower engine can last even longer than the rest of the mower. The rest of the body and parts must be regularly checked and maintained to reach their maximum potential.
