Lawnmowers can differ in appearance from model to model, but they all operate the same way. A lawnmower blade determines how your grass is cut and must be sharp at all times.

While we wish this part to last forever, sadly for us it doesn’t. In this post, I’ll help you choose the best lawn mower blade in the UK.

The Difference In Lawn Mower Blades

All lawn mowers blades are interchangeable so, it is better to choose one that are best suited to your needs.

The Hi-lift bragging and side discharge blade– The 42-inch hi-lift blade is straight with a high-lift. It creates air movement underneath the deck that lifts the grass for a clean cut. This blade is great for bragging or side discharging applications. 

The Sten Hi-lift is the perfect example of long-lasting blades and installation is very easy. It gives your lawn a clean-cut and an overall high-quality product.

The Mulching Blade- Ideal for mulching, however, it is also used for side discharge. When side discharging, mulching blade acts as standard hi-lift but, they produce less dust.

Plus, they are perfect for people who are converting from mulching to discharging applications. The difference between a mulching and the hi-lift blade is: the mulching blades have curves compared to hi-lift, which is straight.

The Arnold mulching blade is another amazing product; the metal is sturdy and fits mowers with 3/8″ & 7/16″ diameter centre hole hub.

Mulching blade

Gator Blades–Gator blades or hi-performance heavy-duty blades are ideal for mowing dense grass. They are thicker than the standard blades and are sometimes used for mulching applications. Unlike the regular blade, it has teeth at the ends that shreds any grass that goes through them.

The Gator blade is strong and doesn’t require regular sharpening. This is a good thing, since with some lawn mowers you may have difficulties removing the blade. 

How To Sharpen Lawn Mower Blades?

There is no right or wrong way to sharpen lawn mower blades. However, your lawn tells you when it’s time to sharpen your blades. If there is a nice clean cut on top of the grass, then your blade is fine.

But, if the grass is all patch up to the top, then you’ll have a problem. Because patchy grass allows disease through and two-three days after cutting you’ll notice your lawn turning brown.

How much you’ll have to sharpen varies from person to person but make sure you sharpen your blade the first time you use your mower.

It also depends on whether the area is rocky and your expertise nevertheless during the growing season, sharpening your blade 2-3 times are recommended.

Removing the blade from your lawn mower

For safety, purposes remove the spark plug wire since the lawnmower can’t start without it. Always tip the lawnmower up when removing the blade. Because if you move it side-to-side then the gas or oil may empty.

Now, you’ll have access to the two knots that are holding the blade. While some people may use a piece of wood to hold the blade in place. I often experience difficulties with this so, I use safety gloves to hold the blade and remove the knots.

The Tools You Can Use To Sharpen Your Mower Blade

An angle-grinder is an excellent tool for beginners: it is lightweight and very easy to use. However, you may experience problems using them, especially when you want to maintain a specific angle to your blade.

A metal file is a cheaper and effective option when sharpening your lawnmower blade. To use: place your blade in a metal vise, trace the angle of the blade and make strokes in one direction until you get a sharp edge.

A cordless drill- If you have a cordless drill with an attachment that sharpens the blade, then this too can work. The attachment has a sharpening stone to the top with the plastic guide to the back.

Remember you are removing metal when sharpening your blade so, make sure each side is even. Before mounting the blade back to the machine, clean any grass left underneath.

I hope this post helps you with all your lawn mower blade needs.
