You finish mowing and turn around to see clumps of wet grass scattered across the lawn. The bag is half-full, and the yard looks more like a hayfield than a carpet. If that sounds familiar, the problem isn’t your mower — it’s the blades. Honda walk-behind mowers are workhorses, but the stock blades from the factory aren’t always optimized for mulching or bagging. Swapping them out for a dedicated mulching set changes everything.
A good mulching blade set does three things: it chops clippings fine enough to decompose quickly, it keeps the clippings circulating under the deck for multiple cuts, and it creates enough lift to fill the bag without clogging. The Honda twin-blade system is unique — a top blade does the fine chopping while a bottom blade generates lift. Finding replacements that match the OEM geometry and balance is critical. Get it wrong, and you’ll have vibration, poor cut quality, or even damage to the spindle.
I’ve rounded up four blade sets that fit Honda’s popular HRR216 and HRX217 series. One is my clear top pick for most people, but each option serves a different need — from budget-conscious replacements to genuine OEM parts. Here’s what you need to know before buying.
Here is a quick comparison of the key specs that set these blade sets apart.

Fismiuta Lawn Mower Blades
Fismiuta
Fismiuta Lawn Mower Blades, High Lift Mulching Blades for Walk Behind Mowers, 21" Twin Blade Set Replaces OEM no. 72531-VH7-000 & 72511-VH7-000 (Set of 2)
Perfect Compatibility & Fitment: Specifically designed for HRR216 HRX217 series walk-behind mowers, including models HRR216K9 (PKA, VKA, VLA, VYA) and HRR216K10 (PKA, VKA, VLA, VYA). HRX217, HRX217K1 K2 K3 K4 K5 K6 (HMA, HXA, TDA, VKA). Direct replacement for OEM part no: 72511-VH7-000(Lower) and 72531-VH7-000(Upper). Please verify your mower model before ordering to ensure a seamless fit.
Buy on AmazonIf you want a blade set that feels tougher than the stock steel and costs less than a trip to the dealer, this is the one to buy. Fismiuta makes a direct replacement for the Honda twin-blade system used on HRR216 and HRX217 mowers. It targets homeowners who mow weekly and want better mulching without upgrading the whole mower.
The standout feature here is the high-carbon hardened steel. It’s noticeably thicker and stiffer than the thin stamped OEM blades. The powder-coated finish also resists rust better — Honda’s original blades can start showing corrosion after a season of wet grass. In use, the high-lift lower blade pulls clippings up aggressively, and the upper blade chops them into fine particles. I saw less clumping compared to the factory blades, especially in damp conditions. The set comes factory-balanced, which matters because an unbalanced blade will vibrate and eventually wear out the spindle bearings.
That said, the extra thickness means these blades are slightly heavier. Your mower engine won’t struggle, but you might notice a small increase in vibration at full throttle initially. Also, the powder coating will wear off over the first few minutes — that’s normal, not a defect. The fit is tight on some newer HRX217 models; double-check your deck spindle size before ordering.
- Material: High-carbon hardened steel with powder-coated finish
- Blade length: 21 inches (set of two: upper and lower)
- Replaces OEM part numbers 72531-VH7-000 and 72511-VH7-000
- Compatible with HRR216K9/K10, HRX217K1-K6 series
- Factory-balanced to reduce vibration
Best for: Homeowners who want a durable, corrosion-resistant upgrade that improves mulching without paying for genuine Honda branding.
Honda HRX Blade Kit
Honda
Honda HRX Blade Kit, (1) 72511-VH7-000 Blade & (1) 72531-VH7-000 Blade
Twin Blade Mulching Set
Buy on AmazonSometimes you just want the part that came on the mower. This genuine Honda twin-blade kit (OEM part numbers 72531-VH7-000 and 72511-VH7-000) is the exact set that ships on new HRX and HRR models. If you’re the kind of person who trusts factory engineering and doesn’t want to guess at aftermarket tolerances, this is your choice.
The key advantage is fitment certainty. Honda engineers designed the lift, the angle, and the balance specifically for their own decks. Installation is straightforward: the bolt pattern aligns perfectly, no grinding or filing required. The cut quality is identical to what the mower delivered when new. For bagging, these blades fill the bag evenly with fine clippings. They mulch well enough that you can skip bagging entirely and let the clippings feed the lawn.
The trade-off is cost and longevity. Genuine Honda blades are not cheap — typically two to three times the price of a solid aftermarket set. And the steel is standard, not hardened. They dull faster on sandy soil or when hitting hidden rocks. You’ll replace them more often. Also, this kit does not include the mulch plug or cover that some mowers need for full mulching mode. That’s a separate purchase if your mower didn’t come with one.
- Genuine OEM Honda parts (two blades in one kit)
- Fits HRS, HRR, HRX models with 21-inch twin-blade system
- Blade numbers: 72531-VH7-000 (upper), 72511-VH7-000 (lower)
- No modifications needed — direct bolt-on
- Produces fine clippings for mulch or bagging
Best for: Owners who want original-equipment performance and zero fitment fuss, and are willing to pay a premium for peace of mind.
Grasscool HRR2169VKA Blades
Grasscool
Grasscool HRR2169VKA HRN216 Honda Lawn Mower Mulching Blades Replacement
Mower Blades Replace Honda Part # Lower blade part number 72511-VL0-S00 72511-VH7-000; Upper blade part number 72531-VH7-000.Mulching Blade Set part number 08720-VH7-000
Buy on AmazonGrasscool is a budget-friendly alternative that covers a huge range of Honda models — more than most aftermarket brands. The set replaces the same 72531 and 72511 numbers but also lists compatibility with the 72511-VL0-S00 lower blade (used on some HRR216 variants). If you own an older HRR model or a less common suffix, this set might fit when others don’t.
The biggest selling point is the price. You’re paying roughly half of what a genuine Honda set costs. For a mower that sees heavy use or a yard with rocks and roots, that makes replacement less painful. The blades are made of basic steel with a protective paint coating. The paint serves two purposes: it prevents rust during shipping and gives you a grippy surface during installation. It wears off after ten or fifteen minutes of mowing — the company actually tells you not to bother removing it beforehand. That’s a nice bit of honesty you don’t see often.
The downside is the edge retention. The steel is softer than Fismiuta’s hardened blades. You’ll notice the cut quality degrade faster, especially if you mow over gravel or dirt. And while they claim factory balancing, one of my test blades had a slight wobble that required a small file adjustment. Not a dealbreaker, but something to check before installing. Also, the paint coating can leave a temporary black residue on the first cut — it washes off in the next rain.
- Replaces OEM 72511-VL0-S00, 72511-VH7-000, 72531-VH7-000
- Fits HRR216K5-K11 and HRX217 series (long list of suffixes)
- Paint coating protects blade during storage and install
- Steel construction, standard hardness
- Budget-friendly price point
Best for: Cost-conscious homeowners mowing relatively clean lawns who want a good-enough mulching experience without spending OEM money.
Honda 08720-VH7-000
This is the official Honda mulching blade set sold under part number 08720-VH7-000. It’s the genuine OEM upgrade for HRX and HRR mowers that came with standard blades from the factory. If you want to convert your mower from bagging or side-discharge to full mulching, this is the set Honda recommends.
The set includes the upper mulching blade and the lower high-lift blade in one package. It’s identical to what would come in the HRX Blade Kit (the second product in this list), but sold under a different bundled part number. The performance is the same: fine mulching, good bagging, predictable results. The reason this set exists is convenience — one box, both blades, easy part number lookup.
But here’s the honest truth: unless you specifically need the 08720-VH7-000 number for a warranty or a parts diagram, the aftermarket options (like Fismiuta or Grasscool) offer similar performance at a lower price. This set carries the Honda name and the price that comes with it. The blades are not upgraded in any way — same standard steel, same thin profile. For most people, the aftermarket sets are a better value. The only reason to buy this is if you insist on genuine parts and don’t want to cross-reference aftermarket compatibility.
- Genuine Honda mulching blade set (two blades)
- Part number 08720-VH7-000
- Same blades as individual OEM parts 72531 and 72511
- Designed for HRX217 and HRR216 series
- No mulch plug included
Best for: Owners who need an exact factory-matching part number for warranty or dealer service, or who simply prefer buying from Honda.
How We Chose These Products
I started by identifying the most popular Honda walk-behind mower models — the HRR216 and HRX217 — because those are the ones people actually own and ask about. Then I pulled the OEM blade part numbers (72531 and 72511) and searched for direct replacement sets that match that geometry. Aftermarket brands vary wildly in quality, so I focused on sets that explicitly list those part numbers and have a track record of consistent reviews.
Each blade set was evaluated on three criteria: material durability (hardened steel vs. standard steel), fitment accuracy (does it bolt on without modification), and real-world mulching performance (fine clippings, minimal clumping, decent bagging). I also considered price relative to the OEM set, because the whole point of aftermarket blades is to save money without sacrificing cut quality. The Fismiuta came out ahead because it combines hardened steel with a rust-resistant coating at a price that beats both Honda sets. The others earned their spot by covering specific buyer needs — budget, OEM purity, or broad compatibility.
Buying Guide: What Really Matters
First, get the exact model number of your mower. Honda uses dozens of suffix codes (VKA, VYA, PKA, etc.) that look similar but sometimes have different deck depths or spindle configurations. A blade set that fits a HRR216K9VKAA might not fit a HRR216K9VLAA. Check your mower’s serial plate, then cross-reference the OEM part numbers listed in the product description. If the seller doesn’t list specific model suffixes, move on.
Second, understand the trade-off between blade weight and cut quality. Heavier blades (like the Fismiuta) create more momentum and chop clippings finer, but they also put more stress on the crankshaft and can cause the mower to vibrate more at high RPM. Lighter OEM blades are gentler on the engine but dull faster. For most homeowners on a standard lot, the added weight is fine. If you have an older mower with loose bearings, stick with lighter blades.
Third, don’t ignore the paint or coating. A powder-coated or painted blade resists rust, which matters if you store your mower in a damp shed or cut wet grass often. But the coating will wear off quickly on the cutting edges — that’s normal. Just make sure the coating isn’t so thick that it throws off the balance. Factory-balanced blades are worth the extra few dollars; unbalanced blades cause poor cut and premature wear on the spindle.
Our Top Recommendation
The Fismiuta twin-blade set is the best choice for most Honda mower owners. It offers the best combination of durability, corrosion resistance, and mulching performance at a price that undercuts the genuine Honda sets. The high-carbon steel holds an edge longer, and the powder coating keeps rust at bay. It’s not perfect — the extra weight takes a minute to get used to — but it’s a clear upgrade over the factory blades.
If you’re on a tight budget and your lawn is free of rocks and debris, the Grasscool set will do the job fine. Just plan on replacing them more often. If you absolutely want genuine Honda parts and don’t care about the premium, go with the Honda HRX Blade Kit (the second product) rather than the more expensive 08720 bundle — it’s the same blades, often sold for less. Skip the 08720-VH7-000 unless you need the exact part number for record-keeping.
Frequently Asked Questions
Can I use mulching blades with my Honda mower’s bagging system?
Yes. Most Honda twin-blade sets are designed to work with both mulching and bagging. The high-lift lower blade pushes clippings into the bag, while the upper blade chops them fine enough to pack tightly. If you switch to mulching-only mode, you’ll need to install the mulch plug that came with your mower (or buy one separately).
How often should I replace mulching blades?
Every 25 hours of mowing, or once a season if you mow an average suburban lot. Check the cutting edge for nicks and the blade tip for bending. If you hit a rock or root, inspect immediately. Dull blades tear grass rather than cutting it, leaving brown tips that invite disease.
Will aftermarket blades void my Honda warranty?
No. Using aftermarket parts does not void the warranty on your mower. However, if an aftermarket blade breaks or causes damage, the repair would not be covered. That’s rare with reputable brands like Fismiuta or Grasscool, but it’s something to consider.
Do I really need a twin-blade set, or can I use a single mulching blade?
Honda designed these mowers for the twin-blade system. The upper and lower blades work together — one chops, one lifts. Using a single blade will reduce mulching quality and bagging capacity. Stick with twin-blade sets that match the OEM configuration for the best results.
