Which lawn mower blade should I buy

One of the primary ingredients of having a great looking lawn is having the right lawn mower blade for the job. For all practical purposes there are really only 3 types of mower blades.

I’m sure you’ve seen mower blades that look totally different than the 3 listed below but essentially they’re all one of the 3 main designs.

The Three Types of Lawn Mower Blades

Depending on where you live in the world mower blade terminology might be a little different. Yeah, I’m talking to you Canada. I know you know what I’m talking a boot, eh!

High-Lift Blade

High-Lift Blade




High-lift blades, commonly referred to as a 2-in-1 blade or regular blade, is the blade you want if you’ll be bagging your grass clippings. High-lift blades are aerodynamically designed for increased air flow which causes the speed of the discharged grass clippings to increase lifting them up and into the air and propelling them up and out of the discharge chute. This blade is ideal for bagging or just really tossing those grass clippings across the lawn…if you’re into that sort of thing.

Typically, high-lift blades are used on riding lawn mowers due to the extra long discharge chute. You’ll need the added lift to get the lawn clipping up and on their way.

Low-Lift Blade

Low Lift Blade



Low-lift blades are great from dry and sandy soils.  The low-lift creates less suction which decreases the amount of dust and debris that’s thrown into the air. Less dust and debris will keep you from choking to death in a cloud of dust.

Mulching Blade

Mulching Blade



Last but not least is the mighty mulching blade. Often referred to as a 3-in-1 blade, these are a very popular choice if you’re not bagging your lawn clippings. That’s not to say you can’t bag with them.  If fact, I personally bag lawn clippings with mulching blades all the time.

Mulching blades are aerodynamically designed to keep the grass lifted in the air under the deck and cut the grass clippings repeatedly into small little pieces of grass. Those little pieces of grass fall down in your lawn and decompose faster providing rich nutrients to your lawn.

Unique in design and appearance, the mulching blade is for all practical purposes a high-lift blade on steroids. Often, the angle of the blade will resemble your average high-lift blade, though some feature increased drag angle on the back of the cutting side, or in some cases air fins which resemble claws. You know, like eagle or bear claws. Scary!

A few things to consider with mulching blades:

  • Mulching blades do not work very well if your discharge chute is not covered or blocked off. For the blade to cut the clippings multiple times and properly mulch them, the grass must remain under the cutting deck. If you’re not bagging you’ll want to equip your lawn mower with a discharge chute cover.
  • You can’t let your grass get too tall.  Cutting grass that has been allowed to grow too long could result in large clumps of grass clippings strewn all over your lawn.
  • You can’t cut your grass if it’s too wet with a mulching blade. Cutting wet grass will often result in messy, soggy piles of grass clippings decorating your lawn and will frequently clog your mower deck. Do this enough and you could cause serious damage to your mower or your mowers engine.
  • You’ll want to keep mulching blades sharp.  A dull mulching blade will have a difficult time re-cutting the grass clippings which could result in clumps of grass being left on your lawn.

Gator Blades are a very popular choice for mulching blades. Gator blades come in three models to choose from depending on your specify needs. The three types of gator blades are listed below.

G3 Gator Blades: G3 blades are designed for smaller engine units. The lower lift on these blades make it a great choice for sandy or abrasive conditions.

G5 Gator Blades: G5 blades provide an optimum combination for a wide range of mower units. Features a high-lift contour as well as two additional, premium features to improve performance and retain blade sharpness.

G6 Gator Blades: G6 Heavy-duty blades are designed for commercial applications and to withstand punishing conditions, while offering the full-range of features that make Gator series blades unique.
