To Sharpen or Replace Mower Blades?
One of, if not the most important steps in servicing your lawn mower, is making sure your mower blades are sharp and in good condition. Blunt mower blades will rip at your grass, which not only looks bad, it isn’t good for the health of your lawn.
How do I know if they should be sharpened or replaced?
In order to determine whether they should be sharpened or replaced you need to inspect their current condition. To do so, tilt your lawn mower up with the front wheels pointing upwards and the handle flat to the ground or bench. This will ensure no oil flows where it shouldn’t, causing you even bigger problems.
If the blades have any cracks, bends, are extremely thin or even have holes in the blade’s fin – then your blades need to be replaced.
If there is still plenty of meat left on your blades and they are in their correct shape, they may simply need to be sharpened.
For most people, the easiest fix is to have your mower blades looked at by a professional. If you are not confident or short on time, your best option is to drop your lawn mower off at your local mower shop and have the experts give the whole unit a once over. It can be a good idea to undertake a mower service every 12 months or so. This ensures your mower is ready to go when you need it during the warmer months.
If your blades just need to be sharpened or you are confident in replacing them yourself, here’s how to go about it for most standard lawn mowers…
How to replace your mower blades
- Socket Wrench and sockets
Allen Key Set
New blades kit
Step 1. Disconnect your spark plug lead from your spark plug.
Step 2. Tilt mower upwards, front wheels in the air and handle to the bench or ground as mentioned above.
Step 3. Using the wrench, you can remove the main bolt securing the base plate to the cutting deck and then blade bolts. Or, you can remove the blade bolts while the plate is still attached to the mower. The blade bolt head may require the use of an Allen key to stop them from spinning while you remove the nut.
Step 4. Remove old blades and put your new blades in place on the bottom of the base plate. The base plate will spin anti-clockwise so make sure the cutting edge of the new blades is directed towards the direction they will spin. A mower blade replacement kit will come with
- a plastic washer that goes onto the bolt on the bottom of the base plate,
- a steel washer for the underside and
- the nut to tighten it in place.
If you are going to sharpen your blades, make sure you are very careful as to only take the slightest amount off the blade and keep it even, so you don’t throw the blades out of balance.
Step 5. Put your new washer and bolts on and secure them in place tightly. The blades should still move if a decent amount of force is applied. This will enable them to absorb a hit from a large obstacle or rock avoiding damage to other components.

Thank you Marcus & Joe for such excellent customer service. Marcus gave us good advice on what turf to use and had no problems coming to offer his advice a second time to help us keep to our budget. Joe and his team were polite, friendly and efficient and did a terrific job on our very large backyard. It looks amazing. We've mowed it twice now and it looks like it has been there forever.
Thanks very much for the photos! The area is looking excellent - a huge improvement on the original !! I appreciate all your team's efforts and hopefully we'll be able to successfully maintain the turf until it is well established!
