Best Lawn Mower Blades for Thick Grass

Disclaimer: All claims are strictly my personal opinion. As an Amazon Associate, I may earn from qualifying purchases.

Having a good sharp blade on your mower not only helps deliver a quality cut but also makes lawn mowing a lot easier. It is also important to look for a sturdy blade that lasts longer and requires less maintenance.

The thing you need to keep in mind is the Toughness & Hardness of the lawn mower blade that will help to withstand higher pressure while dealing with thick grass – the sharpness is the ultimate factor.

The base material for any blade is iron and adding carbon makes it what we call Steel, generally. The carbides make it hard. The heat treatment, later on, improves the toughness.

I’ve gathered some best ones out there to help ease your buying decision, and there’s also a buying guide at the end that mentions some important factors to look for before making your purchase.

Make sure to understand your requirements properly before putting your money for blades as there is not any blade to perform all tasks efficiently.

There are mainly three types of blades depending on your needs;

  1. Lawn Mower Blades for Mulching
  2. Lawn Mower Blades for Bagging
  3. Lawn Mower Blades for Discharging

These have different shapes that I will explain in detail with each product.

But overall, the reviews were positive, and these blades were classed under Amazon’s choice.

They are great for bagging leaves and grass clippings as they are high-lift blades. The blade’s inner part is a bit flat, while the outer part at the backside is curved up.

They are generally priced below some Craftsman blades, so you’ll save some money by buying these if you’re using a mower of that brand.

Buying Guide for Best Mower Blades

High-quality mower blades are the way to go for great cutting performance. It also lengthens the life of the mower and its engine.

Having different types of blades in the market that offer replacement to OEM blades, it is best to choose the right one so that the cutting quality is not compromised with the substandard ones.

So that you know, this guide has been made so that you understand the specifications and some terms that are relevant to the products. So, here are some factors that you should consider before purchasing blades for your lawnmower.

Blade Length

This is probably the first factor to consider when buying a blade. Measure the length of your existing blade, and then search for the relevant replacement.

Generally, the lengths vary between 16.75″ to 22″ depending on its OEM replacement. Sometimes people go for blades that are longer than their original ones in the hope of getting a wider cut. This takes away the strength while spinning, plus it tends to leave its place quite often.

So remember to go for a blade that is of adequate length and which fits firmly in place.

Blade Width

The second thing you need to know is the width of the blade. Typically, blade width varies from 2.25″ to 3,” and it’s important to choose the right one.

Having a wider blade than the OEM may damage the deck or may not even fit at all. Similarly, a narrower blade doesn’t improve the cutting performance. The best way to choose is by referring to the lawnmower manual.

Blade number

A significant factor to begin with. Find the manufacturer number mentioned on your original blade or refer to the user manual. Using this number, you can find the right replacement blade with the right-center hole, width, and length.

Type of Blade

The blades can be either used for discharge, mulching, or bagging purposes. Some blades offer a 2-in-1 or a 3-in-1 design to cater to all these functions. Get the right type of blade that is best for your lawn and your mowing needs.

Lawn Mower Blades for Bagging

These are used for getting the grass clippings from under the deck to the side or rear discharge chute. They have strong curves along the edge that create airflow, which helps lift the clippings after being cut.

It is recommended to use high-lift blades for tackling tall and dense grass, which creates a more powerful airflow but takes up more power from the engine.

Low-lift blades, on the other hand, are suited best on lawns with shorter dry grass. This helps in getting the grass without much debris and dust.

Mulching blades

These blades are made to cut grass clippings into finer pieces. They do this by keeping the clippings in circulation, which allows them to get cut several times. The mulch that is created can then be used to make a good natural fertilizer for your lawn as it decomposes much quicker.

They have long, curved surfaces with sharp edges and a toothed design. They are considered all-purpose and are sometimes referred to as 3-in-1 blades.

The extra effort in slicing those grass clippings draws more power than the discharge function.

Blade holes

Ensure that the blade you’re planning to purchase has the center hole of the right shape. These come in different shapes and lengths that are designed to cater to compatible models.

As you’ve seen from the list, there are star-shaped centers (5-pointed and 6-pointed) with smooth or pointy edges or round-shaped holes with diameters between 0.5″ to 1″. There are also bowtie-shaped center holes that are designed according to the relevant mower’s model.

Final Verdict

Some replacement blades are better than the original ones. They offer increased durability and strength with a cheaper price tag attached to it. But they do require sharpening before using them.

With so many mower blades in the market, it becomes extremely tricky to choose what would fit perfectly and stay in place. To assist buyers, I have managed to find the best 10 products that you can find online at the moment.

I hope that your decision to buy your replacement blade is made easier with this review’s help.

People Also Asked about Lawn Mowers Blades

Here are a few question that people used to ask about these blades;

How sharp should the blades be?

Having a vigorously sharp blade is the first thing that comes to mind. But they shouldn’t be as sharp as razor blades. If you can contact the blade without cutting yourself, that is the right amount of sharpness.

Normally, people make the mistake of buying extremely sharp blades to find that they chip when they come into contact with stones or other debris.

So the right amount of sharpness is the one that can deliver a quality cut and get you speedy results without damaging itself in the process.

How to safely sharpen blades with a grinder?

Here are some safety tips that you can adopt while using a grinder to sharpen your blade.

  • Choose a clean place with no sharp objects lying around.
  • Place your mower blade on a leveled surface.
  • If you have long hair, do tie them together properly to avoid any injury.
  • Avoid wearing loose clothes to protect yourself against any contact.
  • Check the grinder and ensure that it’s operating properly. There shouldn’t be any wires lying around the area where you’re going to use the grinder.
  • Adjust the grinder and check the tongue cards.

How often should you sharpen your blades?

It depends on the number of times you use your lawnmower. If you’re using it to mow your backyard, you should sharpen the blades every year.

For those using it for commercial purposes or on large lawns, the rate would increase and vary from model to model. Therefore, it is best to refer to instructions issued by the relevant manufacturer.

You also get an idea by looking at your lawn condition after being done with your mowing task. If the cat is not clean and even, you need to sharpen those blades.

How to replace the blades?

Changing the mower blade is tricky if you don’t do it the right way. Remember first to unplug your mower’s spark plug cable. Empty the fuel that is left in the tank to cut off any fuel supply completely.

Unscrew the blade bolt and carefully remove the existing blade from its place. For more safety, take a piece of wood and place it between the blade and the cutting deck. Place the new blade in the slot and tighten the bolts.

What to ensure that the blades have a long life?

You can follow the below tips if you want to keep your mower blades well maintained:

  • When mowing, ensure that there aren’t any stones, sticks, or hard plastic on your lawn. These tend to damage the blades’ sharpness and, in worst cases, may even chip off a part of your mower blade.
  • Use a glove or clean cloth to clean the blades and wipe off excess dirt or debris.
  • Lubricate the moving parts of the mower before using it for a smooth run. You can use a silicone spray such as WD-40 for doing this.
  • Always check that the blades are rotating without any contact with the other blades or the cutting deck.

How to retain the blade’s sharpness?

It is always advisable to use any edible oil to coat the blades after they have been sharpened. This would act as a shield against rust and corrosion.
