The life expectancy of a lawn mower is not independent. Various factors determine whether a lawn mower will last till its expected lifetime. While the average lifespan of most lawnmowers is 8.5 years, most are expected to stay functional between 7 to 10 years.

In other words, the life expectancy of lawnmowers can also be expressed in hours. The manufacturers rate many lawnmowers based on the hours of use per week or month. Hence, depending on the rated hours of usage per week or month, you can extend or shorten the lifespan of your lawn mower.

However, the average life expectancy depicts the overall lifespan of the lawn mower. It does not imply that every part of the lawn mower will last that long. You might need to change and replace the parts from time to time, depending on how well you maintain the lawn mower and the intensity of work it does.

As mentioned earlier, the life expectancy of a lawn mower depends on various factors. Starting with the type of grass in your lawn to the consistency in your maintenance. Here we have discussed all the factors that affect the lifespan of a lawn mower, so you can know where you can do the saving.

The Mower Quality

The quality of the lawn mower you bought first plays the most crucial role in determining how long it will last. The quality and price of lawnmowers go hand in hand.

If you own an expensive lawn mower, it will last longer than the cheaper ones. A brand you can rely on it every time usually offers the best quality lawnmowers. However, it may not always be true.

You might be tricked into buying costly lawnmowers with low quality and less life expectancy. Hence, you can not rely on the price for the quality. All you can do is research lawnmowers and buy high-quality ones. A high-quality lawn mower lasts up to the expected lifetime.

Usage Amount

The frequency you use your lawn mower also affects its life expectancy. It is why most manufacturers rate the life expectancy of lawnmowers based on the hours of usage per month or week.

It is evident that if you use your lawn mower frequently, it will reach its lifespan early. On the other hand, the users who carry out the trimming job can rarely use their lawnmowers for more years than expected.

Environmental Factors

The environment you reside in or have your lawn is also a major player in determining how long the mower will last. An environment with extremities can shorten the lifespan of your lawn mower.

Moreover, there is a high chance of your lawn mower rusting early if your lawn is near the sea or in wet areas. It is because of the salty water and continuous wetting of the lawn mower, respectively.

In the same way, both rainy and sunny conditions are suitable for your lawn mower. Such weather conditions may ruin the plastic parts of the mower, thus degrading its quality.

Hence, you must store the lawn mower in a well-furnished storage space. It keeps your lawn mower from losing its functionality before its lifespan.

Operation Intensity

The intensity of operation is another major factor affecting your lawn mower’s lifelong functionality. It relies on the type of grass you cut using your lawn mower, whether thick or less dense.

Long grasses also need the intense operation of your lawn mower. When considering the operation intensity, you must also keep in mind the rated horsepower of the mower. A mower with a low horsepower rating must be used only on smooth terrains, unlike one with a high horsepower rating, which can also last longer on rough terrains.

Hence, the essential part here is to consider the course of your lawn. If you have rough terrain in your lawn, you must go for lawn mowers with high horsepower ratings, else the lifespan of the mower will be short.


It is not enough to admire what you have but to keep it secure. The same holds for lawnmowers. It is necessary to adopt a high-maintenance regime for the mower to avoid worsening things further.

The way you maintain your lawn mower also impacts its life expectancy. For obvious reasons, a mower receiving high maintenance and good care from time to time will last longer.
