How Often Should You Replace Your Lawn Mower?

Lawn mowers are one of the most expensive pieces of garden equipment, so many gardeners take great care of their trusty lawn mower.

However, the time must come when we retire our old lawn mower and replace it with something newer and more up-to-date – but when?

If you want to save money by only replacing your lawn mower when it’s absolutely necessary, then this is the guide for you. We are going to be discussing lawn mowers, maintenance, and part replacements so you can get as much use out of your lawn mower as possible!

How Often Should You Replace Your Lawn Mower?

To save yourself money and reduce waste, you should only replace your lawn mower when it’s absolutely necessary – and how often that is all depends on the type of lawn mower you have and what kind of condition you keep it in.

The average lifespan of a lawnmower is 8.5 years as most lawn mowers break down between the 7th and 10th year of their life. So, be prepared to replace your lawn mower during this period – but if your lawn mower is working just fine, then why bother replacing it even if it’s over 10 years old?

You should only replace your lawn mower when it stops working or is not working as efficiently as it should, and there’s no way for you to repair the issue. This point can come at any time, whether you’ve had your lawn mower for only a few years or over a decade.

As a result, there’s no set time on how often you should replace your lawn mower – it all comes down to each individual lawn mower itself.

How Often Should You Replace Your Lawn Mower’s Blades?

While the lawn mower itself can last years and years before needing replacing, the same can’t be said for its blades.

Good lawn mower maintenance includes replacing your lawn mower blades every single year. This is because, over the year, your sharp blades will become dull and debris from mowing can cause nicks and dents.

These affect the efficiency of your mowing so replacing these blades will help ensure that your lawn mower does a good job each and every time you use it.

You should also sharpen your lawn mower’s blades after every 25 hours of use and check them for corrosion. This maintenance will ensure that you don’t have to replace your blades more than once a year.

How Often Should You Change Your Lawn Mower’s Oil?

You should change your lawn mower’s oil every single year, usually during the spring or summer when your lawn mower is most in use.

Alternatively, some people change their lawn mower’s oils after every 50 hours of use but these people are the type with massive gardens and lawns which need regular maintenance. Most people change their lawn mower’s oil (and oil filters) once every year.

How Often Should You Replace Your Lawn Mower’s Spark Plug?

Spark plugs should be changed and replaced at the start of every season, or after 25 hours of use if you regularly use your lawn mower.

Spark plugs are usually the culprit whenever a lawn mower won’t start so make sure you replace the spark plug every year as part of your lawn mower maintenance – otherwise, you could mistake this for total engine failure and spend way more on repairs or replacements than you needed to!

How To Know When You Need To Replace Your Lawn Mower?

There are two main issues that usually kill a lawn mower – meaning that they cannot be repaired and so, most people end up replacing their lawn mower entirely. These two issues are complete engine failure or transmission problems.

This is because engine failure and transmission problems are the most expensive issues to repair. Generally, the cost to repair these problems is so high that you might as well buy an entirely new lawn mower. In some cases, it’s even cheaper to just buy a new lawn mower than to try to repair your old one!

If your lawn mower is still under warranty, then you can get a free replacement or repair (depending on the terms and conditions of your lawn mower’s warranty) and still keep your old lawn mower.

Another rule that gardeners use as a marker for when it’s time to replace their lawn mower is when the lawn mower requires frequent repairs or just isn’t cutting your grass properly no matter how much maintenance and repairs you do.

When Is The Best Time To Replace Your Lawn Mower?

If your lawn mower is completely dead and it’s time for a replacement, then try and wait until the autumn sales before you make a purchase.

This is because the demand for lawn mowers dips off in the autumn and winter seasons, and shops and stores will be looking to transition their inventory. This means they will be looking to shift as much of the leftover lawn mowers as possible – and will introduce great bargains to achieve this.

However, you need to move quickly to make sure you get the right lawn mower at the right price. We recommend that you start doing your research the moment your lawn mower starts to break down so that when autumn comes, you will know which lawn mowers to keep an eye on for great deals!

In Summary

Most lawn mowers only last around 7 to 10 years but that doesn’t mean you need to replace your lawn mower around this time.

If you keep up your lawn mower maintenance and store it properly during the winter, your lawn mower could last you years beyond its life expectancy – and this can save you a ton of money!

As for certain parts of your lawn mower like its blades and oil, these to be replaced regularly as a part of your lawn mower maintenance. This will keep your lawn mower in great condition so you can get as much use out of it as possible!
