Exmark mowers are known for their durability, reliability, and (of course) signature quality of cut. Just like Exmark makes more than ordinary mowers, their blades are more than regular blades. If you’re weighing Exmark OEM mower blades against aftermarket alternatives, here’s everything you need to know before you buy.
What Makes Exmark OEM Mower Blades Different?
Simply put, that signature cut is the result of thousands of hours of testing to achieve a blade unlike any other. Exmark designs everything about their mower blades to perfection. From airfoils unique to each deck size, to perfectly engineered blade tip speed and a precisely sharpened edge, every single aspect has been considered.
Exmark also manufactures multiple blade types built for specific mowing applications:
- Bagging blades efficiently move air and clippings into the bag.
- Mulching blades feature alternating airfoils that break clippings down finely.
- Rear discharge blades throw finely-chopped clippings further and more evenly away from the mower.
No matter how or where you mow, there’s an Exmark OEM blade designed for that exact job.
How Durable are Exmark OEM Blades?
Exmark engineers blades to a unique level of hardness; they’re not too brittle or soft, nor are they too heavy. This combination ensures that when mowing, you get a properly weighted, and hardened, blade that reduces the impact from any rocks or debris.
As proof of their durability, their engineers run impact tests where they launch a one-inch spike directly into a blade running at 220 miles an hour. The result? Just a minor dent not even the size of your thumbnail.
Exmark OEM vs. Aftermarket Mower Blades: What’s the Difference?
Exmark OEM mower blades aren’t the only blades their engineers put to the test—they evaluate aftermarket blades, too. In fact, nearly 84% of aftermarket blades evaluated fail to meet Exmark standards. They might get the length and other larger details right, but it’s all in how and what the blade is made of that makes the difference.
Exmark manufactures blades for Exmark mowers and rigorously tests them for various applications and types of grass. Exmark offers a wide variety of blades with different lengths, airfoils, heights, thicknesses, and widths to match different deck sizes and situations. Meaning you can mow properly, based off the type of grass you have in your yard.
In contrast, aftermarket manufacturers might get the blade length close enough, but fail when it comes to the finer details. With non-OEM blades, you risk:
- Incorrect blade length that doesn’t match your deck.
- Wrong cutting angle that compromises cut quality.
- Improper hardness that leads to faster wear or unexpected breakage.
- Generalized airfoil design not optimized for your grass type or mowing conditions.
Best of all, with an Exmark blade you receive an industry-leading warranty. With aftermarket products you forgo that option—and fail to achieve such a superior quality of cut.

Frequently Asked Questions About Exmark OEM Mower Blades
Exmark OEM (Original Equipment Manufacturer) mower blades are factory-engineered replacement blades designed specifically for Exmark mowers. They are built to match exact deck specifications, blade tip speed requirements, and airflow designs to deliver the brand’s signature quality of cut.
Exmark OEM blades are developed through extensive engineering and testing, including:
- Application-specific airfoil designs
- Deck-specific blade configurations
- Precisely engineered blade tip speed
- Optimized cutting edge geometry
- Controlled hardness and weight balance
In contrast, many aftermarket blades are built to general specifications and may not match the fine-tuned details required for optimal performance.
Using non-OEM blades can create performance and safety risks, including:
- Incorrect blade length
- Improper cutting angle
- Poor airfoil design
- Incorrect hardness or thickness
- Reduced cut quality
- Faster wear or potential breakage
Even small variances in design can impact airflow, discharge performance, and overall lawn appearance.
Yes. Because OEM blades are designed specifically for Exmark deck systems, they help maintain:
- Clean, precise cuts
- Proper airflow under the deck
- Even clipping distribution
- Consistent blade tip speed
These factors contribute directly to healthier turf and professional-looking results.
