Can the REVO6 String Trimmer Head Replace Traditional Mower Blades?
Have you noticed the REVO6 string trimmer head attachments popping up in your social media feed? Same here. They’ve gone viral, and I’ve seen reports claiming these trimmer heads are better than traditional mower blades. Bold claim, right?
I had to see for myself. So, in this post, I'll walk you through what the REVO6 is, how it's installed, and, most importantly, how it performs compared to regular metal blades on a mower. Spoiler: it’s not all sunshine and roses.
What Comes in the Box?
First of all, this isn’t a sponsored post. No one’s paying me to say nice things about the REVO6, so let’s just get that out of the way.
The product I got is the REVO6 2.0. The box included:
- A metal adapter to replace your existing mower blade
- Six trimmer lines (hence the "6" in REVO6)
- Some washers
The setup feels heavy-duty, mostly made of aluminum and secured with solid screws. The way it works is pretty simple—you feed the trimmer lines into ratcheting holes, and they stay locked in place. You get string to load the trimmer twice—once right out of the box and then for a reload.
Customer Service Experience
I’ll give props where props are due: customer service was on point. The owner of the company personally called to confirm my mower’s measurements, which is impressive. His story? He lives in Texas, where mowing often involves dodging rocks, roots, and holes, all of which tear up blades. Out of frustration, he invented the REVO6 to handle these rough terrains without breaking windows or shooting debris through the air. It's designed to be safer—especially in areas where flying rocks are a concern.
How It Works
The REVO6 replaces the traditional blade on your mower’s deck. Instead of sharp steel cutting grass, you get six strings whipping around at high speeds to cut it. Sounds interesting in theory, but my main concern right away was the lack of lift.
Traditional metal blades have a sail built in to create lift, which helps pull the grass up for a cleaner cut. The REVO6 doesn’t have that, so I wondered right away how it would perform without that feature, especially in thicker or wet grass.
Installation was mostly straightforward, but it's crucial to know the size of your mower's blade hole. I misjudged mine at first, and the hole sizes didn’t match, which forced me to make adjustments. If you’re buying the REVO6, make sure to get the correct size.
Testing the REVO6 in St. Augustine Grass
Walking into the test, I already had my doubts. My first grass test was on a lawn full of thick, juicy St. Augustine grass mixed with weeds.
The immediate thing you’ll notice? It’s LOUD. When you turn on the REVO6, it sounds like twelve individual string trimmers buzzing at once. The noise mostly comes from wind resistance due to the six strands whipping through the air.
Once you get onto the grass, the strings do self-correct and quiet down, but the noise is still close to an actual string trimmer.
However, the cut quality was a letdown. It left a lot of grass behind, and I ended up needing to go over a few sections twice. Traditional blades have a precise cut—they slice through the grass like butter. The REVO6? Not so much. It felt more like tearing than cutting, and the lawn looked uneven and ragged after the first pass.
Where Does It Shine?
Despite the poor cutting quality on St. Augustine, the REVO6 did have some upsides in other areas.
I found that it excelled in high-risk zones with lots of obstacles. Think backyards with stubborn roots that peek out from the soil or areas with rocky terrain. Normally, a metal blade would take a beating on stuff like this, but the REVO6 just bounces off these types of hazards without taking damage.
For example, when I hit a stump, the REVO6 strings bent and slipped over it without any issues. On the same stump, my old mower with steel blades had broken a spindle. So, if you’ve got tricky, obstacle-filled patches, this tool might be a good fit.
How About Wear and Tear?
The manufacturer claimed the string could last for around eight acres, but during my testing, it didn’t seem like that would be the case. After mowing less than a quarter of an acre, I noticed significant wear on the strings. That’s far less wear time than regular steel blades, which can last for months before needing sharpening.
Strings are easy to replace, but replacing them so often feels like a hassle—and an extra expense.
Testing in Tall Dry Grass
Next, I took it out to an abandoned golf course with tall, dry grass. Dry grass should cut easier than the thicker, juicy St. Augustine, but even here, the results were mediocre at best. The REVO6 managed to beat down taller blades of grass, yet it still didn’t offer the crisp, clean cut you’d expect from standard blades. Once again, I had to go over certain areas multiple times, which isn't something you look forward to when mowing large areas.
Can It Handle Sandy Environments?
One area where the REVO6 might actually be useful is in sandy environments. I tested it over a section with powdery sand—similar to what you'd find in a sand trap on a golf course. Sand is notorious for damaging metal blades and causing suction issues.
The REVO6 performed much better here. It didn’t create the suction you'd get from a metal blade, meaning it didn't blow sand everywhere or damage the mower deck. If you're dealing with sandy or rocky terrains regularly, this could be a niche solution. It clearly reduces wear on equipment in these conditions.
Is It Worth the Money?
Bottom line: if you’re a regular homeowner looking to mow your grass, the REVO6 is not the game-changer some claim it to be. The cut quality just isn’t on par with traditional blades.
But it’s not without some merit. For special situations—like mowing around roots, rocks, or other obstacles without damaging your mower—it’s pretty impressive. If you’re a contractor dealing with unpredictable terrain, this might be worth a test run.
For most residential users, though, replacing or sharpening steel blades still seems like the better, more cost-efficient choice.
Final Verdict
If you mow your own grass and want clean cuts, stick to traditional blades. The REVO6 feels well-engineered, but it’s not suitable for most homeowners or professional landscapers working with standard lawns. The strings wear out quickly, and the cut quality just doesn’t match up to steel blades.
However, if you’re dealing with rough or hazardous terrain—roots, rocks, or dry fields—the REVO6 might save your mower from severe damage. Just be prepared for the continuous cost of replacing string.
At around $260 for the kit, plus the recurring cost of strings, this product is for a very specific subset of users. But for those niche applications, it’s a solid choice.
