Changing the blade on a riding lawn mower is a task that should be done at least once a year. Replacing the blade can save you money by preventing unnecessary wear and tear on other parts of your machine, like belts or spindles. 

It also means less time spent in maintenance costs over time. This is true even if your new sharpened blades do not last as long as possible.

The process for changing blades varies depending on what kind of ride-on mower you have: push, self-propelled or riding (or some combination of these). Generally speaking though, it is recommended that you remove all debris from around the area before working with sharp objects such as blades and nuts/bolts which may cause injury if dropped accidentally into your lap while seated on top of an operating vehicle!

To change a blade, you’ll need:

A socket wrench set appropriate to your mower’s bolt size. If you don’t have one and are unsure which size to get, check with your local hardware store or call them ahead of time to make sure they can order it in for you (it’s unlikely that they will carry all sizes).

Next, remove the old blade using a socket wrench and replace it with your newly sharpened one. If there are any loose screws or bolts on your starter pulley, be sure to tighten them down again before reinstalling the deck assembly back onto your machine. 

Lastly, put in a new spark plug and tighten it down with pliers if necessary while ensuring that they are seated properly in their holes so as not to cause any damage when starting up again later on!

To replace a lawn mower blade, begin by removing the bolt that holds the blade in place. A screwdriver is usually used for this task. Next, remove the old blade and install a new one by lining up its holes with those on your lawn mower’s deck.

Remove the old blade by unscrewing it from its mounting bracket using an adjustable wrench or socket wrench.

 If your mower has a blade bolt locking mechanism that prevents unthreading during use (some models do), remove this before proceeding to step 

Check that your mower deck is level when operating; if not then adjust accordingly so that it does not cause uneven wear on either side as well as causing unnecessary strain on your engine and transmission components over time leading up towards potential breakdowns later down line which could cost far more than what was spent initially on changing out both blades at once!

What Are Some Tips For Changing The Blades On Your Lawn Mower?

To change the blade on your lawn mower, first use a socket wrench to loosen and remove the blade from your lawnmower. Make sure you have the correct size socket wrench for your lawnmower, as well as the correct size blade for your model of mower.

Once you have removed the old blade, clean off any rust or debris from underneath it using sandpaper or steel wool (depending on whether or not there is rust). If there is rust present, go ahead and apply some oil to prevent further corrosion before installing your new blade.

Check the blade tension. If the blade is loose, tighten it and recheck the blade tension to make sure it’s tight enough to cut grass effectively but not so tight that you damage your lawnmower by over-tightening it.

Make sure the blade rotation is smooth and even throughout its entire length. If there are any rough spots or vibrations in either direction (clockwise or counterclockwise), remove a few inches of grass from each side of that spot so you can get an unobstructed view before sharpening your blades again until they’re even all around their circumference.

Check alignment: Make sure your mower deck isn’t tilted at an angle higher than three degrees (three degrees being just slightly more than one inch). If it is tilted higher than three degrees, adjust it by loosening bolts with an Allen wrench until they’re level; then retighten them firmly once more before continuing with step 4 below!

To change the blade on your lawn mower:

  • Remove the spark plug wire from your machine by loosening its hex head screw with an Allen wrench, then disconnecting it from its male terminal inside the engine compartment (this will prevent accidental starting).
  • Remove any bolts holding down the deck shroud (if there are any), which will give you access to where blades are located beneath it; most likely there’ll be one or two bolts attaching each end of deck shroud onto side rail brackets attached under mower’s body panels

Remove the old blade by loosening the bracket that holds it in place.

Clean off the deck to remove any debris and smooth out any rough surfaces. You can use sandpaper or a file during this step if necessary.

Apply a lubricant to the new blade, such as motor oil or silicone spray lubricant, before installing it on your lawn mower. This will help prevent rusting and make your blades last longer than they would without any lubrication at all!

Install the new blade onto both sides of your lawnmower deck by aligning it with its nearest bolt hole and tightening down each side evenly until snug but not overly tight (you don’t want to strip out those bolts). If you need extra leverage when tightening things like this then feel free use some kind of wrench tool like pliers instead

Remove the old blade from its mounting brackets and discard it. You may want to save a sharpened blade for later if you plan on sharpening it again or need a spare in case something goes wrong with your new one.

Check the blade for damage before installing a new one: Look for cracks, chips, and dents; these could cause problems when cutting grass later on. 

It’s also important to check that the blade mounting surface is clean (i.e., free of dirt or debris), as this will help ensure that your new sharpened blades don’t get stuck while they’re cutting through grass during future mowing sessions!

Install your new blades onto their corresponding mounting brackets: Make sure you’re inserting them correctly so they’re facing where they should go once installed if not installed correctly then they won’t work as intended during future use! 

Just make sure nothing gets caught between them while being installed either since it could damage both pieces beyond repair after repeated use over time…

What Are Some Tips For Extending The Life Of My New Sharpened Blades?

Keep the blade sharp. A dull blade will not cut grass as well as a sharp one and will quickly wear out. When you need to replace your lawnmower blade, be sure that it is sharpened before reinstalling it so that you can get the best results from your mower’s performance.

Clean the deck regularly with a brush and/or hose attachment. The more visible buildup such as dirt and grass clippings, the less your mower will be able to process them into mulch or compost material for fertilizing purposes which could lead to damage over time if left unchecked – especially on older models! If possible, try cleaning off any excess build-up before starting up each time so that there is less resistance against moving parts when they start turning again plus makes clean up after use easier too! 

Also remember not leave anything sitting around outside like toys etc because this may cause rust which could lead us back at square one again soon after getting done cleaning everything off just now only adding more stress onto an already stressful situation where trying hard not think about how many years ago my father bought this thing from Walmart.


And so, you have learned how to change the blade on a lawn mower. You can now go out and do it yourself with confidence! Remember that this process should take only about an hour or two of your time. And then, when you’re done, enjoy all those beautiful blades of grass.
