Best Lawn Mower Blades: Reviews of our Top Picks

One of the most important and often overlooked elements to your lawn care program is your lawn mower blades. 

Having a dull or chipped lawn mower blade will lead to a poor quality of cut. 

Dull lawn mower blades will aggressively rip and tear leaf blades compared to a sharp blade which will give a smooth clean and even cut. 

This is important for a couple or reasons. 

  • First, cutting with a sharp straight blade will put significantly less stress on your lawn.  When grass is stressed it will disperse stored nutrients and water leaving your turf discolored. 
  • Second, when a grass blade is ripped instead of cut cleanly it will leave the leaf blade open to common turf diseases and fungus.  Curing these problems are often expensive and time consuming. 

These issues can be prevented in part by making sure your blades are in good condition.

If you have never changed your blades before or it’s been a couple of seasons with the same blades now is the time to replace or upgrade.

Our list of blades will consist of factory replacements as well as upgraded blades for some of the most common lawn mowers on the market.

Things to consider when purchasing new blades for your lawn mower

Blade Fitment

The easiest way to determine fitment for your new blade is to reference the model number for your factory blade. 

If you are unable to locate the factory model number on the blade or in your owner’s manual a simple search online including your mower type and model will lead you to the factory specs of your blade.

If you are still having trouble determining what blade will fit your mower best here are a few things to consider

  • Blade Length
    Measure your blade in a diagonal direction from tip to tip to determine the overall length of the blade.  Having this measurement correct will insure the blade will fit properly seated in the mower deck. Note, that going smaller to insure fit will leave grass uncut in strips.
  • Mounting Hole Configuration
    The mounting spindle is what will attach your new blade to your mower.  These spindles come in many different configurations so proper identification will relieve frustration and get you back to mowing sooner.  Use the common patterns listed below to help you determine your needs
    • Rounded: Measure the diameter
    • H Pattern
    • Y Pattern
    • Star Pattern: 5, 6, and 7 star 

Blade Performance

A couple of things to consider when choosing a blade. First find a blade that is classified as high lift. 

This feature will help with suction as the blade spins and “lift” as it’s being cut to ensure and even uniform cut.

Most mowers have a mulching or side discharge function.  These features are used when you are not bagging and wish to return your clippings to the lawn for added nutrients.  If you are using one of these two features make sure the balde you chose has a mulching capability that will cut a blade into finer pieces which will decompose faster.

Blade Coating

Whether you chose a factory replacement or an aftermarket blade it will be delivered with some sort of powdercoated or painted edge. 

To get the most out of your new blade it is best to use a file to lightly remove this coating to reveal your new sharp edge. 

To do this file perpendicular to the edge in one direction along the factory beveled edge.  This is also a good task to perform at the beginning and of each season to prolong the life of your new blade. 

This simple task will keep your blade sharp and remove any imperfections like rock gouges to keep you blade in top working order.


When removing or changing your blade it is best to always remove to boot from your spark plug.  This often overlooked step is vital in ensuring safety while changing your blade. 

Failure to do so may result in your blade spinning and turning the engine and the engine firing.

  This simple step will remove that dangerous possibility.  

Another tip to make your conversion easier is to block your blade with a scrap piece of 2×4 so your blade does not spin as your are removing the spindle bolt. 

To do this place your 2×4 perpendicular to your blade deep into the mower deck’s discharge hole.  Slowly rotate the blade the blade until it contacts the 2×4 and is wedged in place.
