Best Mower Blades for Zero Turn Mowers in 2021

The essence of a great mower is all about your mower blades. No matter how powerful your engines are or how fast your mower runs, it’s nothing but a piece of metal if your blades are dull, worn, and absolutely messed up. Mower blades don’t last forever, from all the intense cutting and trimming of your grass, your blades are bound to wear out and require replacement. With that said, here’s a full guide to help you choose the best mower blades for your zero turn mowers.

Choose The Type Of Blade You Need

Just picking out the right sized blade for your z-turn is not enough. When looking for mower blades to replace your worn out blades, you’re going to come across two main types of blades: Standard Blades and All-Purpose Blades.

  • Standard Blades

These types of blades are the ones that often come with your zero turn mower. They are made for moving clippings aside and discharge the cut grass away from your mower. Standard blades are also known as 2-in-1 (discharging and bagging) blades, lifting blades, or simply, discharging blades.

What do these blades do?

A standard blade’s main function is to simply cut and bag. It is divided into two types: flat and lifting blade.

Flat or non-lift blades give that smooth pristine cut. But they don’t bring in a needed lift to provide a more polished look. This is perfect for clean lawns; it can pose a problem when your grass gets too tall because flat blades can knock down the overgrowth instead of cutting.

The second type is lifting blades because they function by “lifting” the grass and cutting them. The blades have a curve along the opposite edges. These curves create a space for air to flow, thus pulling the grass up before it’s cut.

The lifting effect makes it easier for the blade and mower to dispose of the clippings to a bag or out the mower. When looking for standard blades, you need to consider the type you’re going to need.

  1. High-lift. This is ideal for tall tough grass, weeds, and light brush. These require a large horsepower engine of at least 22HP since it requires more power to cut tough greenery easily.
  2. Medium-lift. This is great for large lawns or property with dense grass. However, it cannot handle a mild brush.
  3. Low-lift. This type of standard blade is designed for common lawn solutions from cutting grass to gentle weeds, and this is the ideal type for your mower.

What’s the downside in getting standard blades?

Standard blades should never be used for mulching purposes because the blades aren’t designed for it. You will wear out your blades and even potentially destroy your mowing deck in the process.

  • All-Purpose Blades

Don’t we all love anything with the label all-in-one, in this case, these types of mower blades can discharge, mulch, and bag your clippings. These all-purpose blades, or 3-in-1 blades, combine the task of cutting and mulching making mowing more efficient.

What do these blades do?

All-purpose blades are mainly for mulching. Hence they’re also called mulching blades. The blades have smaller jagged edges on the sides to make the mulching process much easier. However, some 3-in-1 blades have extended blades to have a wider cutting surface in place of the serrated edges. The cutting edges are raised to make the clippings circulate within the mowing deck and cut each clipping several times.

Smaller grass clippings easily decompose, making them great sources of natural fertilizer. Since it’s also harder for smaller cuttings to be seen, it adds to the manicured look on your lawn, giving you a smoother greener looking property after mowing.

What’s the downside in getting standard blades?

Unfortunately, mulching blades exhaust your engine faster because it requires more energy to cut clippings multiple times. It would also require a mulching kit and proper installation. Mulching blades are more costly since not a lot of z-turns are sold with a mulching kit.

  • Bagging Blades

It’s not so common to find bagging blades nowadays because they’re already incorporated with the standard and all-purpose blades. As the name suggests, these blades are only intended for bagging.

Factors to Consider in Buying Blades for Zero Turn Mowers

Once you’ve considered what type of blades you need, you have other considerations to make before you make your purchase.

Finding the Perfect Fit

The most crucial factor to consider is the fitting of your mower, mowers all have different sizes even if they have the same mowing path. Different brands create their mowing deck differently. Knowing the precise specifications of your blades is vital in choosing the right blade for your mower.

With so many z-turn brands and models out there, many have specific sizing, features, and lengths for their mowing deck. You have to take note of the following before getting a mower blade:

  • OEM Manufacturing Number 

All mower blades have a manufacturing number. It’s a set of 6 numbers that provide specifications for the length, thickness, and blade hole. The manufacturing number is the most crucial information you need to know when you’re going to buy blades for your ZTR. 

  • Model Name or Number

In the absence of the OEM number, you should know the brand, model, and number of your mower. With this, you can easily find blades that will fit your mowing deck.

  • Length and Center Hole

Without the OEM number or the model type and number, you can still find the right blade for your mower as long as you know its length and the type of center hole it has.

Measure your blade diagonally to get the right length, and simply inspect the center hole design. Som mower blades only require a round hole while others have a star design to improve the mower’s grip on the blade.

Material

You want durability at its finest when choosing the best blade for your ZTR, and one of the considerations you need to make is the material used.

Firstly, it should be a solid metal alloy. You don’t want something welded together since this creates weak spots that can become points of breakage in the future.

Secondly, choose a blade that doesn’t have any coating or only has a light coating of paint. The coating can chip off over time, and the speed of your spinning mower blades can turn these small chipped off the coating of your blade into small dangerous flying objects.

Value for Money

Many ZTR owners opt to buy non--OEM blades simply because they are cheaper. This may be true, but the overall cost of ownership should be your priority. Original equipment manufactured mower blades will always ensure that your blades are the right fit for your mower.

Generic brands making mower blades may be more affordable now, but it could come at the cost of lower quality and inappropriate fitting. For that reason, I came up with this list to give you trustworthy choices for your zero turn mower blades.

Durability

The strength of your blades also matters. When it comes to durability, I highly suggest getting standard blades or flat all-purpose blades. Although serrated edges are great for mulching, they are prone to breaking because even a small stone can get stuck and chew on the notches of the blade.
