Overview

This is not a lawn mower itself, but a genuine Honda 2-pack replacement blade set designed specifically for Honda HRR216 and HRX217 series mowers. Priced at $32.99, this kit includes both the 72531-VH7-000 and 72511-VL0-S00 blades, which are the exact OEM parts for models like the HRR216VKA, HRR216K9VKA, HRR216K9VKAA, and HRR216K10VKAA. It’s built for owners who want factory-grade cutting performance without aftermarket guesswork.

Who Should Buy This

Honda HRR/HRX owners who value precision. If you own one of the compatible models listed above, this is the blade set that came on your mower from the factory. It’s ideal for anyone who wants to maintain that original cutting quality—especially if you’re tired of aftermarket blades that don’t fit right or leave uneven stripes.

Homeowners with 1/4 to 1/2 acre lawns. These blades are engineered for Honda’s twin-blade “MicroCut” system, which mulches clippings finer than most single-blade setups. If you mow a medium-sized lawn weekly, this set keeps your deck performing at peak efficiency.

Mulching enthusiasts. The HRX217 is famous for its mulching capability, and these blades are the heart of that system. If you want to return clippings to your lawn as nutrient-rich dust rather than clumps, this is the kit you need.

DIY mechanics who change blades annually. At $32.99 for two blades, this is a fair price for OEM parts. If you sharpen or replace blades every season, this pack gives you a spare ready to go.

Key Features Breakdown

OEM Fitment (72531-VH7-000 & 72511-VL0-S00): These are genuine Honda parts, not cheap knockoffs. The blade shapes and mounting holes are identical to what shipped on your mower, meaning zero vibration, no wobble, and perfect alignment with the deck’s airflow. Aftermarket blades often save a few dollars but can cause uneven cutting or excessive engine strain.

21-Inch Length: Standard for HRR216 and HRX217 decks. This size provides the right overlap for a clean cut without bogging down the engine. Too short, and you’ll leave uncut strips; too long, and you risk scalping or hitting the deck housing.

Twin-Blade Design: The HRX217 uses two blades spinning in opposite directions to create a vacuum that lifts grass before cutting. This set replicates that exact airflow. The result is a finer mulch and better bagging performance compared to single-blade mowers—even on damp grass.

Heat-Treated Steel Construction: Honda’s factory blades are hardened to hold an edge longer than budget options. Expect 20-25 hours of mowing before noticeable dulling, depending on your lawn’s debris load. They’re also balanced from the factory, so you won’t need to rebalance them before installation.

Compatibility with Honda’s Versamow System: If you have an HRX217 with the adjustable mulching/bagging/discharge lever, these blades work seamlessly with all three modes. No swapping needed—just install and go.

Pros

• Perfect fit, every time. No filing, bending, or cursing. These bolt right on with the factory hardware.
• Superior mulching. The twin-blade setup chops clippings into fine particles that disappear into the turf. No raking or bagging required for most weekly cuts.
• Reduced vibration. Unlike some aftermarket sets that cause handlebar shake, these are balanced to Honda’s specs. Your hands and arms will thank you.
• Longer edge life. The heat-treated steel resists dulling from sand and small rocks better than generic stamped blades.
• Two blades for the price of one (almost). At $32.99 for a pair, you’re paying about $16.50 per blade. That’s competitive with aftermarket options, but you’re getting genuine Honda quality.
• Backed by Honda’s reputation. If you ever have a fitment issue (rare), Honda support is straightforward to deal with.

Cons

• Not universal. These blades only fit specific HRR216 and HRX217 models. Double-check your mower’s model number before ordering—the compatibility list is precise.
• Price premium over generic blades. You can find 21-inch blade sets for $10-$15 less on some sites. The trade-off is fitment and durability, but if you’re on a tight budget, that difference matters.
• No included hardware. The kit comes with blades only—no bolts, washers, or nuts. If your old hardware is rusty or stripped, you’ll need to buy replacement fasteners separately.
• Mulching-focused design. If you primarily bag or side-discharge, these blades still work well, but you might not notice as much benefit as someone who mulches heavily. For bagging, some users prefer a dedicated high-lift blade.

Bottom Line

This 2-pack of genuine Honda blades is the right choice for anyone who owns a compatible HRR216 or HRX217 mower and wants to keep it cutting like new. The fitment is flawless, the mulching performance is excellent, and the price is fair for OEM quality. If you’re a weekend warrior who mows a medium lawn and values a clean, even cut without clippings everywhere, buy these. If you’re on a strict budget or own a different mower model, look elsewhere. For Honda owners, this is the blade set that should be on your shelf.

Frequently Asked Questions

Q: How do I know if these blades fit my specific Honda mower?
A: Check your mower’s model number—it’s usually on a sticker under the rear flap or on the engine shroud. Compatible models include HRR216VKA, HRR216K9VKA, HRR216K9VKAA, HRR216K10VKAA, HRX217HYA, HRX217VKA, and others in the HRR216 and HRX217 series. If your model ends in a different suffix, verify with Honda’s parts diagram online.

Q: Can I use these blades for bagging instead of mulching?
A: Yes. These blades are designed for Honda’s Versamow system, which adjusts the airflow for mulching, bagging, or discharge. They work well in all modes, though they’re optimized for mulching. For heavy bagging, you might get slightly better lift from a dedicated high-lift blade, but most users find these satisfactory.

Q: How often should I replace these blades?
A: Replace them once a season or after 25-30 hours of mowing, whichever comes first. If you hit rocks, roots, or other debris, inspect the blades immediately for nicks or bends.
