Your ride-on lawn mower is an expensive piece of equipment so regular checks should be part of ensuring that you get the most out of your machine. Carefully following your manufacturer’s instructions regarding how to check the blades – or if you don’t have one, ensuring the machine is off of course – look under your machine to review the blades.

If your blades are a little rounded on the blades, these may be ok, and just need a sharpen, but if they are riddled with holes, cracks or are bent, then you need to look at replacing them to get your machine humming.

If you’re not sure, ask a friend that has some experience with a ride on mowers or have a chat with your local lawn mower specialist before you jump into checking your blades.

Step 2
Pick your workspace, so you safely sharpen your blades

Firstly ensure that you are in a safe workspace with a reliable surface, park your ‘noble steed’, lock the breaks, turn off the engine and chock up the wheels, so you are ensured it won’t get away from you when you are working.

Secondly, look for the spark plugs. Once you have found them for additional safety, unplug them to ensure nothing kicks on when you have your hands in the blades! Net you will be setting up the blades so that you can access them a little better.

Step 3
Set up the blade for access – make sure you are safe during the setup

Ensuring that your blades are set on the highest settings, so you get access to it, raise the mower using either a set of ramps – available from auto stores & hardware stores – or use a solid service like a log to allow yourself room to access the blades for work.

We always recommend using the commercially manufactured jacks or ramps as they offer you the greatest safety while working on the ride-on, remembering that your ride on is extremely heavy, so take every precaution possible.

Ask a friend to give you a hand if you think you need a buddy, safety first every step of the way!

Step 4
Get the right tools for the job

If you don’t have the right tools, you will struggle to not only to take off and put back on the bolts, but you may strip thread making things a lot harder as you move along. So the key is to get a ratchet set with a range of fittings.

The best way to select the right fitting for the nut is by testing it before you attach to the ratchet. When you have the right fitting, attach it to your ratchet, and you are ready to get started.

If you don’t have a ratchet set, don’t run out and buy one when you don’t need to, simply visit and hire one from someone in your local area!
