Mower Blade Buying Guide for Homeowners

Choosing the right mower blade can be a bit overwhelming, especially with all the options available. A sharp blade is essential for a clean cut and to prevent damage to your lawn.

The type of mower blade you need depends on your lawn type and the conditions it's in. For example, if you have a lot of weeds, a blade with a high lift angle can help to throw them out of the way.

A standard mower blade is usually around 20-22 inches long and has a thickness of around 0.25 inches. This size is suitable for most residential lawns.

It's also worth considering the material the blade is made of, with steel being a popular choice due to its durability and affordability.

There are several types of lawn mower blades to choose from.

Shredding blades are a popular option, known for their serrated edge that helps direct and push grass clippings for finer mulching. They're versatile, but may struggle with tall grass.

Shredding blades are also much louder than other types of blades, so if noise is a concern, you may want to consider a different option.

Reel or cylinder blades are used in reel or cylinder mowers, creating a scissor-like cutting action. They're composed of three to seven helical blades welded in a horizontally rotating cylindrical reel.

These blades can't be replaced individually, so if one breaks, you'll need to replace the entire mower. Cleaning and sharpening kits are available for dull or rusty blades.

The unique design of reel/cylinder blades makes them a distinctive feature of reel or cylinder mowers.

Twisted High Lift blades are a unique type of mower blade that features a twisted end, which alters the angle of the cutting edge. This twist creates a more aggressive cutting action.

The cutting edge of a Twisted High Lift blade angles upward, so there needs to be an adjustment to compensate for that angle. This is why some mowers, like the Model 5005, come with the necessary angle adjustments to fine tune the grinding edge to your preference.

Some mower brands, such as John Deere, often incorporate Twisted High Lift blades into their designs.

Shredding blades have a serrated edge that directs and pushes grass clippings, allowing for finer mulching.

These blades are versatile and can be used for various lawn mowing needs, but they can underperform in tall grass.

Shredding blades produce significantly more noise than other types of lawn mower blades, so be prepared for a louder mowing experience.

They're a great option if you want to create a finer mulch, but keep in mind that they might not be the best choice for thick or long grass.

Low-lift blades are perfect for cutting dry and short lawns, especially in dusty or sandy conditions. They produce less dust, noise, and debris compared to other types of blades.

Low-lift blades have a lower lift angle, which means they generate less suction and airflow. This makes them ideal for side discharge mowing.

High-lift blades are a popular choice for cutting tall, compact grass. They provide the greatest suction power among all types of lifting blades.

A high-lift blade requires a powerful engine to reach peak performance. This is because they need more horsepower to function effectively.

High-lift blades have a steeper angle design that creates better suction and airflow. They're efficient at lifting and collecting grass clippings.

High-lift blades are often utilized for bagging applications, but they're not suitable for dusty or sandy terrain. This is because they can cause significant blade wear.

Twisted high-lift blades, also known as high-lift blades, have a unique twist on the end that alters the angle of the cutting edge. They require an adjustment to compensate for this angle.

High-lift blades can be found on various brands, including John Deere, which often incorporates them into their mower designs.

The deck is a crucial part of your mower, and understanding its features can help you choose the right blades for the job.

There are different types of deck blades available, but the most commonly used one is the standard or straight mower blade.

This type of blade is designed for general-purpose mowing and is suitable for most lawns.

Standard mower blades are the most commonly used type on rotary mowers.

They have a straight and simple design, which makes them ideal for well-manicured lawns. You can grind a 30-degree edge on these blades if needed.

Standard blades provide limited lifting and mulching capabilities, so they're not suitable for wet or tall grass.

Counter-Rotating blades are used by some mowers, including Walker mowers, and they rotate in the opposite direction. These blades have the cutting edge on the other side of the blade.

To adjust for counter-rotating blades, you'll need extra range of motion to reach the cutting edge at the bottom of the jig. This is where extended guide arms come in, which are a feature of our Generation 2 models.

The 35 degree setting works well with Walker blades, making the Model 5005 a recommended choice if you're planning to sharpen Walker mower blades.

When choosing a mower blade brand, consider the type of grass you're cutting. For example, if you have a lot of thick or tall grass, a blade with a high lift angle like the 60-degree angle blade might be more effective.

Some popular mower blade brands include Husqvarna, which offers a range of blades for different mowing tasks, and John Deere, which is known for its high-quality blades designed for durability and performance.

Gator mulching blades are a bit more complex than they appear. They have mulching fins, but it's the cutting edge that needs to be sharpened.

The cutting edge of a Gator mulching blade has a slight tilt forward, which is why a 35 degree setting is best to keep the factory edge. This is a finding from our research, and it's a good idea to follow this setting to get the best results.

If you're using a Gator mulching blade, you'll want to use the Model 5005 to grind at the 35 degree angle. This will help you get the best sharpening results and maintain the factory edge.

The Gator mulching blade is similar to the Ferris blade, which also has a slight tilt forward and works best with the 35 degree setting.

Honda is a popular brand for mower blades, and for good reason. They offer a range of unique designs, including the Quadracut and MicroCut Twin Blade sets.

These sets have a special shape and require a specific adapter to be mounted in jigs. We recommend using the Model 5005 in conjunction with the Honda Adapter to match the factory bevel.

Some Honda mower models, such as the HRN216, HRN216VKA, and HRN216VKAA, may be able to be sharpened without the need for the adapter. This is a great convenience for lawn care enthusiasts who already have these models.

The upper blades for these models, such as the 72531-VR8-M00 and VR8-M00 W154825, can be sharpened without the adapter. The same goes for the lower blades, including the 72511-VR8-M00 and VR8-M00 W154945.

These blades pull the grass up and cut it, then chop the clippings into smaller pieces, which are then blown out to feed the soil. Mulching blades are perfect for natural lawn fertilization.

Commercial Bi-level Mulching Blades are a bit more complex, with the outside cutting edge parallel to the mounting surface and the inside mulching section edge raised and stamped at a different angle. They require a specific type of blade, like the Model 5000, to switch between the 30-degree setting on the outside edge and the 15-degree setting for inside mulching edge.

Mulching blades have a unique design with a distinct curvature and wider cutting edge, which helps lift and cut grass clippings into smaller pieces. However, they don't work well on overgrown lawns because the excess grass clippings can clog the mower.

It's essential to note that mulching blades don't have as much discharge power or suction capabilities as high-lift and standard lawn mower blades.
