Buyer’s Guide: How to Choose the Best Lawnmower Blade

Lawnmower turned upside down

It might seem straightforward enough, but getting the right blade for your mower is actually a little tricky and it takes some thought before jumping in.

Below, you’ll find a handy buyer’s guide and FAQ section to help you make the right decision. This is what you should be looking out for.

Type of Blade

First of all, you need to consider what type of blade you’re going to need. This will depend on a variety of factors and what kind of results you’re hoping to achieve.

Deck/Standard Blades

These blades are regular blades with a straight edge. They’re used for bagging or side dispatching the grass clippings.

Low/High Lift Blades

Low/high lift blades are blades that are useful depending on the terrain.

Low lift blades have less suction and are advisable for use in sandy or heavy soil conditions.

High lift blades are the opposite, providing more suction that is ideal for bagging while significantly reducing the number of clippings that might get stuck in the cutting deck area.

Medium lift blades are also available that offer a half-way house option.

Mulching Blades

Mulching blades are used to give the grass a much finer chop and scatter the clippings back onto the lawn in an effort to improve lawn health.

Gator Blades

These blades offer medium lift with a mulching feature. They’re also known as 3-in-1 blades.

Remember, the type of blade you choose will depend on how you want to cut your lawn and the type of terrain and conditions you’re working in. You might also need a mower with more horsepower to use certain blades.

For more information on lawnmower blade types, refer to the informative video below.

Blade Length

It might go without saying, but blade length is very important when you’re looking to replace your lawnmower blade.

Too long and it might not fit your model of mower, too short and you’re not going to get an efficient cut that maximizes the mower’s deck size.

Refer to your manufacturer’s instructions if you’re in any doubt of the size of the blade you require. Failing that, measure your lawnmower so you have an idea of how long your replacement blade will need to be.

Mower Make and Model

Again, it might seem like I’m being Captain Obvious, but I can’t stress enough how much you need to double-check that your mower’s make and model is compatible with the blade you’re purchasing.

There are literally hundreds of reviews out there complaining that the blade didn’t fit. This isn’t the fault of the seller – it’s the fault of the buyer.

Buyer beware!

FAQs

Question mark on a chalkboard

How Do I Know When To Sharpen Or Replace My Lawnmower Blade?

Unless you’re mowing lawns or landscaping professionally, you’ll most likely want to sharpen your blades once every few months through the season.

Depending of course on the size of your lawn and how often you mow it. Sometimes, you’ll only need to sharpen your blade once through the year.

There’s no hard and fast rule to this – as you simply need to keep an eye on the performance of your mower and blade. Minnesota Equipment has a good example of that, read it here.

If it’s not doing the job it was bought to do, then something needs to be fixed.

Always check your mower blade before and after mowing. A damaged blade will need to be replaced, as it will impede performance and is likely to be bad for the mower itself.

Damaged blades can also cause injury in a worst-case scenario.

Likewise, dull blades will need to be either sharpened or replaced. So, if you’re seeing a dip in the usual cutting standard, it might be time to get an edge back on your lawnmower blade.

Check the grass as you mow. Are you getting a nice, clean-cut? Is there any scalping? Is it taking you longer than usual to do the job?

Blades don’t last forever, so after you’ve sharpened a lawnmower blade a number of times you should be thinking about replacing it.

How Do I Sharpen My Lawnmower Blade?

You can either use your own tools at home or take it into a professional tool shop to have it sharpened for you.

There are a number of excellent blade sharpening tools on the market, or you can simply use a bastard file.

Sharpening in your home will save you time and money – so investing in an angle grinder or a good lawnmower blade sharpener is a sound investment in the long run.

For more information about sharpening your own blades, see the video below.

How Do I Replace A Lawnmower Blade?

Unfortunately, most blades don’t actually come with any instructions on how to replace them. It’s just something we’re all expected to figure out by ourselves.

If you still have your original mower instructions, that should have a section included on how you replace the blade for that particular mower.

While the techniques and instructions might vary from mower to mower, the safety advice remains the same.

Make sure the mower is off, disconnect the spark plug and wedge the blade with a tool or a block of wood.

Always wear a pair of good quality work gloves to protect your hands.

After that, check out the video below for tips on how to replace your lawnmower blade successfully.

How Do I Know Which Mower Blade Will Fit My Model Of Lawnmower?

A good question. As mentioned, it can be very confusing due to the sheer number of blades and fixings on the market. It can be tricky to find the right one.

Once again, you should be referring to the manufacturer’s instructions to guide you in choosing the right blade for your mower.

Look at the center hole of the blade – which can be circular or up to a seven-pointed star shape. There might be blades that have a different shape entirely.

Certain blades have more than one hole – check to see if these products match up to your mower.

Measure the mower cutting deck to make sure you order the right sized blade.

When in any doubt, double-check with the manufacturer if a particular blade will work in your machine. Most manufacturers will tell you that only official parts should be used, but that’s not always true in most cases.

You can always contact the blade manufacturer and inquire if a particular blade will fit a particular model of mower.

With a little bit of research and common sense, you should be able to easily source replacement blades for many years to come.

How Do I Clean My Lawnmower Blade?

Even if you don’t need to sharpen or replace your lawnmower blade, you should always keep it as clean as possible so it’s running at peak performance.

Getting into a good maintenance regimen will also ensure your tools last longer and are much more efficient.

It’s a good idea to remove your blade from time to time to inspect it for damage and give it a good clean while you’re at it.

You can give the underside of your mower a good blast with a garden hose, cleaning off any loose debris and clippings. Many mowers will come with a water port for easy cleaning.

Once you have the blade removed, use a stiff wire brush or another abrasive tool to scrape off any remaining muck or residue.

Coat the blade with a bit of lubricating oil. Once you’re happy with the results, you can return it to the mower and you’re good to go.

What Type Of Blade Is Best For My Lawn?

Ahhh, now this is the age-old debate. It really depends on so many factors and what you want to achieve.

The condition of your lawn also plays a significant part in helping you decide what kind of blade you need to tend it. The type of terrain you’re mowing is equally important.

Most of the time, it’s really up to you and it boils down to how you want to use or dispose of the grass clippings.

Blades with a high lift are ideal if you want to bag the clippings and then dispose of them later. The improved suction will ensure the grass is lifted up and away from the blade and into the bag at the back of your mower.

When bagging, you can also mow in nearly all conditions and get a high-quality cut.

The downside here is that you have to stop mowing regularly to empty the bag.

Blades that are better for side discharge are preferred by mowing professionals. This is because they can get the job done much faster by never having to stop mowing.

You can also mow in most conditions, the job will be done in double-quick time and you’ll still get a nice finish.

The negative here is that the clippings tend to be thrown everywhere. This can lead to more work should you wish to clean them up.

Mulching blades are one of the most popular options. This is because they dice the grass into finer clippings and deposit them back on the lawn. This is to mulch the lawn and improve its overall health.

You can only mulch if the conditions are right (dry and shorter grass), and even though it’s a slower job, you’ll still be able to none-stop mow.

Of course, it also depends on the length and type of grass, as well as how much debris is scattered in your yard.

Summary

It’s certainly not the most exciting topic, but replacing your lawnmower blade is important from time to time – especially if you want to keep your lawn looking spick and span.

So, I hope this little review and guide has gone some way to helping you find the best lawn mower blades for your needs.

Of course, it depends on your mower, but I like the look of the Oregon, 3-in-1 Gator mulching blade. It’s a tough and durable part, inexpensive, and is versatile enough to fit almost any walk-behind mower.

Let me know which mower blade you’re going for and why.

I wish you the best of luck with finding the right blades for your lawnmower. May we all have lawns as beautiful as the 18th hole at St Andrew’s.
