Viral lawn gadgets spark curiosity, but some claims need a closer look before you buy. The REVO6 2.0 String Trimmer Attachment has flooded social media, promising to replace steel mower blades with spinning string heads—right under your deck. The pitch is simple: safer mowing, less damage from rocks and roots, and a fresh option for tough mowing conditions. But does it actually work? Will it leave your yard looking sharp, or are you better off with the usual metal blades?

In this post, I'm unpacking, installing, and testing the REVO6. I'll compare the cut to traditional blades, break down strengths and weaknesses, and help you decide if this bold new mowing idea fits your needs.

Every product begins with a problem. For the REVO6, that issue started in Texas, where rocky, rough lots destroyed traditional mower blades. The REVO6's creator needed something for mowing over rocks, mole hills, and holes dug by turtles and gophers. Conventional steel blades kept getting ruined, flinging debris through windows and leading to expensive mistakes.

Rather than give up, he teamed up with a friend to create a new attachment. One designed not for perfect stripes, but for durability and safety on wild land. He even called to confirm my mower’s deck size before shipping—real customer service, and a welcome change from faceless online stores.

“I built this to survive Texas rocks. We needed it for mowing fields full of gravel, roots, and holes,” the owner told me. This personal approach and deep understanding of rough-terrain mowing shaped the REVO6’s features.

Here’s what sparked the idea and who might need it:

• Pain Point: Constant blade damage from rocks, roots, glass, and debris
• Key Features: Durable aluminum build, six-string design, easier on windows and mowers
• Best Fit: Properties with roots or rocks, construction sites, fields with hidden debris, or jobs where blade strikes mean big repair bills

There’s something exciting about opening a viral gadget. The REVO6 packaging is pretty simple, but the parts inside feel solid and ready for work.

Inside, you’ll find:

• Three REVO6 trimmer heads (string units)
• Extra pre-cut trimmer string (enough for one reload for each head)
• Metal adapter and washer (to replace your mower’s steel blade)
• Instruction sheet

The main head is made of aluminum, giving it a strong, heavy-duty feel. Each unit holds six tough trimmer strings, which click into place with a ratcheting slot. To load, you just push the string into the slot, and it locks in. Pull through with pliers to change strings—fast and simple.

The “six” in REVO6 stands for six lines extending from the head. That’s three heads (for a big mower deck), each slinging six lines. In theory, that should knock down weeds and grass faster and more evenly.

Here's a quick summary:

• REVO6 Trimmer Heads: 3 total (enough for a full wide deck)
• Extra String Sets: 3 (one spare set per head)
• Adapter & Washer: For attachment to your mower
• Material: Aluminum body, sturdy screws, thick trimmer string
• Special Line: The included string is designed for flatness, longevity, and stability at high speeds

Ordering the kit means picking a package. I got the “Rancher Pro” setup: three heads, enough string to reload them once, and adapters. Other bundles are available if you only want one or two heads.

First impression: Strong build, easy string changes, but limited replacement string in the box. You might end up dependent on the supplier for more refills, unless aftermarket line fits.

Getting a new mower attachment in place is usually straightforward—until you hit compatibility snags. That happened here.

My mower’s blade hole was larger (15/16”) compared to the 5/8” hole on the REVO6 adapter. That mismatch matters: too big a hole, and the head wobbles, risking uneven cuts and damage. Here’s what I tried:

1. Test fit the adapter and washer on the blade spindle
2. Check for wobble or “play” in the fit
3. Experiment using bushings and bolts to center and secure the trimmer heads
4. Tighten everything slowly and evenly
5. Repeat for each spindle (three on my deck)

The adapter shape helped keep the head mostly centered, even with the size gap. After tightening each bolt, I found it wasn’t a perfect fit—some movement remained, but not enough to stop testing.

Key tip: Before you order, measure your blade hole and check with the seller for the right adapter size. An ill-fitting head can create noise, vibration, and faster wear.

Here’s a quick step-by-step for swapping and replacing string:

1. Slide the old mower blade off the spindle
2. Place the REVO6 head and adapter onto the spindle
3. Make sure the fit is snug with minimum play
4. Tighten bolts as recommended in the kit instructions
5. To change string, push new string through the slot and pull with pliers

Warning: If the heads aren’t snug, the mower may run rough or feel unstable.

The moment the REVO6 spooled up, the sound changed—loud air movement, almost like running a dozen trimmers at once. It was harsher and more “hollow” than steel blades. Stopping the heads also happened much faster, likely because the string units are lighter than steel.

Once in the grass, the noise dropped a lot. The string ends self-corrected quickly, trimming themselves as they struck the turf and found an even length. After a minute, the sound settled. Still, if unique noises bother you, this setup stands out.

“Like running 12 string trimmers at once.”

I started testing in a typical yard with healthy St. Augustine, some weeds, and uneven turf. Here’s what jumped out:

• Cut quality was rough compared to steel blades. Grass was left long in patches, and the finish was uneven.
• Performance dropped to about 60-70% efficiency versus metal blades.
• Strings wore quickly in dense grass, losing up to half an inch in under an acre of mowing.
• Pros: I could mow over roots and hidden stumps without fear—if a string hit, it just glanced off.

Pros and Cons Recap:

• Pros: No blade damage or risk mowing over roots/stumps. Good for rough, uneven yards.
• Cons: Cut was ragged, with grass left behind. Needs more string changes. Not ideal for a manicured lawn.

Next, I tried the REVO6 on tall, dry patches in a field (similar to an abandoned golf course rough). Performance was similar:

• It knocked down tall grass , but the cut looked uneven and unfinished.
• String wear increased. In just an acre or so, each string had lost noticeable length.
• Grass didn’t choke the mower , possibly because no suction was created like traditional decks.

Findings and Use Cases:

• Best fit for tough, dry grass or “brush hog” jobs
• Easy on mower health , less brush jammed under deck
• Not for normal lawn care where a uniform finish is needed

Finally, I tackled a patch of thick grass growing out of an old sand trap. Here, the REVO6 showed an unexpected advantage:

• Almost zero suction , so sandy soil stayed put instead of blasting holes in the deck or getting flung everywhere
• The mower rolled smoothly over soft ground with its wide tires
• Little risk of deck or blade damage from sand—perfect for construction sites, sandy jobs, or even lots filled with debris

Advantages in Sand or Rocky Soil:

• Protects the mower deck in abrasive conditions
• Reduces risk to people or property (fewer hard objects flung by steel blades)
• Still not great for a perfect cut , but ideal for “just knocking it down” scenarios

The REVO6 2.0 has a clear strength: safer, less damaging mowing on rough, rocky, or overgrown terrain. If you price in ongoing string refills and the initial kit (about $260), it’s a cost you won't face with steel blades that last all season long.

Here’s what I found:

• Cut quality falls short. String leaves long strands, doesn’t mulch or lift clippings, and needs replacing after just an hour or so of heavy use.
• You’ll depend on the company for more replacement line, at least until compatible alternatives arrive.
• Best suited for special jobs: clearing lots, mowing rough land, or protecting machines when hidden debris is a risk.
• Not recommended for regular residential lawns or fine finish work.

When to consider the REVO6:

• You maintain foreclosed properties where cinder blocks or bricks could be hiding
• You mow rocky sites, sandy patches, or construction zones
• You want to protect your mower assets from hidden hazards at all costs

When to pass:

• You care about a clean, even cut on everyday grass
• You mow thick lawns that need frequent string changes
• You want lower operating costs and less refilling

Pros vs Cons

The REVO6 is a cool invention, built with passion. But for most landscapers and homeowners, steel blades remain the better call—at least for now.

All tests ran on a Toro GrandStand HDX. This mower is comfortable, with springy suspension and wide tires to handle bumpy, root-filled lawns. Interested in the mower itself? Check out the  Toro GrandStand HDX 72 in. EFI with Oil Guard  for full specs.
