Looking to buy Lawn Mower Parts & Accessories?

Gardens are an extension of our homes and, as such, we should take just as much care to look after them as we do the inside of our property. Though gardening may seem like an arduous task for some, particularly those that aren’t so naturally green-fingered, it needn’t be a chore. Over the years, the gardening industry has grown from strength to strength, with leading brands, such as Bosch, regularly developing new innovations to meet the demands of the modern consumer. As such, you’ll now find a whole host of different gardening tools and machines in sheds belonging to most homeowners across the world, with everything from the humble lawn mower to more advanced tillers, strimmers and more. 

Heavy-duty gardening equipment can be quite an investment, and there’s nothing more gut-wrenching than when your expensive piece of kit starts playing up. Instead of forking out for a brand new machine, take a look at OnBuy’s vast selection of lawn mower parts and give your handy garden appliance a new lease of life. With everything from spare tyres to replacement blades, roller axels, nuts and bolts, clutch cables and more, we have all the bits and bobs you need to get your lawn mower performing as it should, helping to prolong its life and prevent any bank-breaking expenses!  

What’s wrong with my lawn mower?

When it comes to diagnosing the problem with your mower, there’s a whole host of things to look out for. It’s not uncommon for your lawn mower to have trouble starting up, particularly after the long winter months when they’re rarely in use. It’s always a good idea to do some routine maintenance on your mower to keep it performing as it should but, even with due cue, you may still end up faced with a breakdown and unsure where to start to get your machine back up and running again. Here are some of the most common things to look out for if your lawn mower is experiencing problems. 

First of all, if your mower requires petrol to run, double-check that the tank is filled up. It may sound simple but, especially after not using your machine for a while, it’s an easy thing to miss. It may also be worth replacing any old petrol with a fresh tank, as this can cause issues with your mower starting up too. Speaking of fuel, make sure your fuel filter or carburettor isn’t clogged, as this can prevent fuel from reaching the engine.

If the problem doesn’t lie with petrol, give the spark plug a clean and see if that helps. If cleaning off debris doesn’t fix the issue, you may have a faulty spark plug that’ll need replacing. Likewise, test your start switch with an ohmmeter – if there’s an intermittent fault or it’s difficult to turn, this may be the culprit of your problems. 

If you own an electric lawnmower, your first point of call should always be the power source. Make sure your mower is connected to a live and working power supply before getting stuck into further troubleshooting – it may sound silly, but it’s a common mistake! The problem may be as simple as a blown fuse or tripped breaker in the socket, so try plugging in another appliance to the same power source to see if that works. If it does, you may well have found the source of your problems. 

Another thing that may stop your electric lawn mower starting is a full cuttings bag or a build-up of grass and debris in the blades. With your mower unplugged, disconnect and empty the cuttings bag if needed and carefully clean the blades of the blockage. 

Other common problems to look out for include a damaged lawn mower cable, which would need to be fixed as a matter of urgency, or a faulty on/off switch. Luckily for you, all the replacement parts you could ever need can be found right here on OnBuy’s lawn mower parts shop. So, once you’ve diagnosed the issue, get your hands on the relevant part and carry on with your gardening tasks with ease!
