Keeping your lawn healthy and thriving demands some amount of regular TLC — for the grass, leaves, and flowers. A freshly landscaped yard doesn’t just look beautiful, but it also boosts the growth of your garden. For that, you need the best lawn mower blades that are sharp enough to cut through effortlessly.
A high-quality blade will evenly eliminate unkempt patches, keep your yard nice and trimmed, and take relatively less time to work with than a blunt or unsuitable regular blade. You can check out our list of top-rated recommendations for lawn mower blades right here, and if you are still unable to select the right one, read our buying guide to know how to decide.
Types of Lawn Mower Blades
Different lawn mower blades have different uses according to their functions, which is essential to make the right choice. There are three types of lawn mower blades:
Discharging blades: These blades discharge debris into bags or push grass away. They are most suitable for push mowers because they lift the grass to cut it down, hence, they are also called high-lift blades.
Mulching blades: These all-purpose blades, usually called three-in-one blades, have curved and serrated edges to cut the grass into finer pieces and then pour it back into the ground. The innermost curve of the blade generates air pressure to blow out the small debris into the soil. Mulch blades also allow proper distribution of air, which is a plus.
Gator blades: They offer medium lift and provide softer, smoother, and cleaner cuts of the grass. They are most suitable for lower-level grass.
If you are looking for a sturdy, functional, and high-performance replacement blade for an MTD, Cub Cadet, or Troy-Built lawn mower, this high-lift blade by 8Ten is a suitable choice.

How To Choose The Right Lawn Mower Blades?
Here are the features you must look for while purchasing a lawnmower blade.
Width of the blade: Wide blades can cover more area and reduce the time you spend on the mower. But at the same time, a large width may damage other components of the lawnmower. The ideal width is two to three inches.
Length of the blade: The perfect length and width provide high efficiency for the blade. For short mowers, the optimal length is 16 to 22 inches. There are also blades up to 30 inches in length.
Blade holes: The center hole design can vary depending on the blade. A simple central hole will loosen over time and may require a washer. Five or six star holes provide a firmer grip. Before purchasing, you must also check the size of the attachment bolts in the mower. •
Deck size: This factor largely depends on the size of the lawnmower. The smaller the deck size, the smaller should be your blade size.
The shape of the blade: Try to purchase blade replacements that are similar to the original blade. Check for blades that are compatible with your lawnmower for the best fit.
The number of blades:Push mowers and self-propelled lawn mowers only require single blades. Riding lawn mowers may require more than one.
Material: Stainless steel blades have a longer service life. If the construction is too thin, the blades may bend during use. Similarly, if you plan to use a lawnmower on wet grass, consider using an anti-rust model.
Frequently Asked Questions
1. When should I sharpen or replace my lawnmower blade?
If you do not regularly use the lawnmower, you can hone it every season or every few months. This factor depends on the size of the lawn. The larger the lawn area, the greater the need to sharpen the blade more often.
2. How should I choose a mower blade for my lawnmower?
Always refer to the manufacturer’s guide and customer reviews to check if the selected product is ideal for your lawnmower. Before looking for a replacement blade, you must check the center hole, length, and mower width. You must also check whether the mower is compatible with blades that contain multiple center holes.
3. How should I clean a lawnmower blade?
Here’s how you can clean a lawnmower blade. First, wear rubber gloves, turn the lawnmower over, avoid tilting sideways to prevent oil leakage, and remove the spark plug. If there is any debris stuck, remove it by hosing it, and clean all hard residues with a wire brush.
