Overview

This is not a lawn mower itself, but a set of genuine Honda replacement blades designed specifically for 21-inch deck Honda mowers in the HRB215, HRB216, HRB217, HRM215, HRS216, and HRT216 series. Priced at $25.00 with a flawless 5.0-star rating from 20 reviews, these blades (models 72531-VE2-020 and 72511-VE1-020) are OEM-quality replacements for homeowners who want to restore factory cutting performance without paying dealer prices. They’re best suited for anyone who already owns one of these Honda mowers and needs a sharp, durable blade that fits perfectly.

Who Should Buy This

  1. Honda HRB/HRM/HRR/HRS/HRT owners with dull or damaged blades – If your mower is leaving ragged cuts or vibrating excessively, these exact-match blades will bring back that clean, mulching performance you bought the Honda for in the first place.

  2. DIY homeowners who avoid dealer trips – Instead of driving to a Honda dealer and paying $35-45 per blade, you can order these online for $25 and install them yourself with a socket wrench in under 15 minutes.

  3. Buyers who want OEM quality over cheap knockoffs – Aftermarket blades often have thinner steel or wrong hole patterns. These are genuine Honda parts, so you get the same heat-treated, balanced steel as the original blade that came on your mower.

  4. Anyone with a 21-inch deck who needs a spare blade – Having a sharp backup blade means you can swap in minutes and sharpen the dull one at your leisure, keeping your mowing schedule uninterrupted.

Key Features Breakdown

  • Compatible Models: Fits HRB215, HRB216, HRB217, HRM215, HRS216, HRT216, and related 21-inch Honda mowers. Check your model number on the deck sticker—this covers the most popular residential Hondas from the late 1990s through 2010s.
  • Blade Length: Standard 21-inch deck length. These are not for 22-inch or 20-inch decks. Measure your old blade if unsure.
  • Construction: Heat-treated stamped steel with a hardened cutting edge. This is the same material Honda uses on factory blades—not the soft, thin steel you get from generic brands.
  • Center Hole & Mounting: Precision-punched center hole and drive pin slots match Honda’s exact specs. No wobbling or misalignment during installation.
  • Finish: Coated with a rust-resistant paint. It will wear off at the cutting edge after a few uses, but the blade itself won’t corrode quickly if you store the mower dry.
  • Quantity: Typically sold as a single blade. If you need two (for a twin-blade deck), verify your model—most 21-inch Hondas use one blade, but some HRM models use two.

Pros

  • Perfect OEM fit – No filing, no shimming, no wobble. These drop right onto the spindle and line up with the drive pins exactly as intended.
  • Restores factory cut quality – A fresh Honda blade cuts grass cleanly rather than tearing it, which reduces browning at the tips and gives you that manicured look.
  • Durable steel holds an edge – The heat-treated alloy stays sharp longer than cheap aftermarket blades. Expect 10-15 mowings before needing a touch-up.
  • Balanced from the factory – You won’t get vibration that stresses your spindle bearings or makes the handle shake. That’s a common problem with unbranded blades.
  • Costs less than dealer pricing – At $25, it’s roughly 30% cheaper than what a Honda shop charges for the same part number.
  • Backed by Honda engineering – These are OEM parts, not “compatible” knockoffs. You get the same quality control as the blade that came with your mower.

Cons

  • Single blade only – If your mower uses two blades (some HRM215 models), you’ll need to buy two, which doubles the cost to $50. Check your deck before ordering.
  • No included hardware – The bolt, washer, and blade driver (if your mower uses one) are not included. Reuse your old hardware or buy new if it’s worn.
  • Not for universal fit – These only work on the listed Honda models. They won’t fit Toro, Craftsman, or other brands, even if the deck size is the same.
  • Paint wears quickly – The rust-resistant coating isn’t heavy-duty. Expect it to chip off along the cutting edge after the first mowing. This is cosmetic only—the steel underneath is fine.

Bottom Line

If you own a 21-inch Honda mower from the HRB, HRM, HRR, HRS, or HRT series, these genuine blades are the smartest $25 you’ll spend this season. They restore factory performance, eliminate vibration from worn or mismatched blades, and cost less than a trip to the dealer. The only catch is confirming your model uses a single blade—if it does, buy one and you’re set for a year of clean cuts. For the price and reliability, there’s no reason to gamble on generic replacements.

Frequently Asked Questions

Q: How do I know if this blade fits my specific Honda mower?
A: Look at the model number on the sticker under the grass catcher or on the deck. It should start with HRB215, HRB216, HRB217, HRM215, HRS216, or HRT216. Also check that your deck is exactly 21 inches wide. If your mower has a 22-inch deck, these won’t work.

Q: Do I need to sharpen these before first use?
A: No. They come sharp from the factory. Install them as-is and you’ll get optimal cutting performance immediately. Sharpen only after 10-15 hours of use or when you notice ragged grass tips.

Q: Can I use these on a Honda mower with a twin-blade system?
A: Only if your specific model uses one blade per spindle. Some HRM215 models have a two-blade setup. If your deck has two blades, you’ll need two of these blades—but verify the part number for your model first, as twin-blade systems sometimes use different blade shapes.

How It Compares

Head-to-Head Comparison: Lawn Mower Blade vs. Battery Charger

Quick Verdict

There is no winner because these are completely different products—Mower A is a replacement lawn mower blade, while Mower B is a battery charger—so the choice depends entirely on what you need.

Side-by-Side Comparison

Spec Mower A (deawater Blade) Mower B (NOCO GENIUS1)
Price $25.00 $29.95
Power Source Manual (fits gas mower) AC wall outlet
Cutting Width 21 inches N/A
Self-Propelled No (it’s a blade) N/A
Best Yard Size Small to medium lawns N/A (charges batteries)
Warranty Not specified 3-year limited

Where the deawater Blade Wins

  1. Direct compatibility with Honda mowers – Specifically fits HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 models, ensuring a perfect fit without modification.
  2. Perfect 5.0-star rating – All 20 reviews are positive, indicating consistent quality and sharpness for a replacement blade at a low price.
  3. Affordable maintenance part – At $25, it’s a cost-effective way to restore cutting performance without buying a new mower, saving you hundreds of dollars.

Where the NOCO GENIUS1 Wins

  1. Versatile multi-battery support – Charges 6V and 12V lead-acid (AGM, flooded, gel) and lithium batteries, covering cars, motorcycles, boats, lawn tractors, and power equipment.
  2. Smart safety features – Includes overcharge protection, temperature compensation, and desulfation technology to extend battery life, preventing damage from improper charging.
  3. Proven reliability with massive user base – Over 62,000 ratings with 4.4 stars demonstrate widespread trust and real-world performance across countless applications.

Which Should You Buy?

  • Buy Mower A (deawater Blade) if: You own a compatible Honda mower (HRB215, HRR216, etc.) and need a sharp, affordable replacement blade to restore a clean cut to your lawn. It’s a simple, direct swap for a worn or damaged blade.

  • Buy Mower B (NOCO GENIUS1) if: You need to maintain, charge, or revive any 6V or 12V battery—whether for a car, motorcycle, lawn tractor, or boat—and want a safe, automatic charger that prevents overcharging and works with modern lithium batteries.

  • Buy Neither if: You are looking for a complete lawn mower (self-propelled, gas, or electric). The deawater is only a blade, and the NOCO is only a charger. You need a different product entirely.

Head-to-Head Comparison: deawater Lawn Mower Blade vs. Battery Tender Junior

Quick Verdict

These two products are not direct competitors—one is a replacement blade for a Honda mower, and the other is a battery charger—so the “winner” depends entirely on whether you need a mower part or a battery maintainer.

Side-by-Side Comparison

Feature Mower A: deawater Blade Mower B: Battery Tender Junior
Price $25.00 $37.95
Power Source Manual (fits Honda gas mowers) 120V AC to 12V DC
Cutting Width 21 inches N/A
Self-Propelled No (blade only, not a mower) No
Best Yard Size N/A (replacement part) N/A (charger/maintainer)
Warranty Not specified 5-year limited warranty

Where deawater Blade Wins

  1. Precision fit for Honda mowers – Compatible with HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 models, ensuring a direct OEM-style replacement without modification.
  2. Perfect 5.0-star rating – All 20 reviews are positive, indicating consistent quality and sharpness out of the box for a low price.
  3. Cost-effective maintenance – At $25, it’s a budget-friendly way to restore cutting performance on a popular Honda mower deck, extending the life of your existing machine.

Where Battery Tender Wins

  1. Universal 12V application – Works on motorcycles, ATVs, lawn tractors, cars, boats, and more—far more versatile than a single mower blade.
  2. Proven reliability – With nearly 50,000 reviews and a 4.8-star average, it’s one of the most trusted battery maintainers on the market, backed by a 5-year warranty.
  3. Automatic smart charging – Unlike a trickle charger, it switches to float mode once the battery is full, preventing overcharging and extending battery life—ideal for seasonal equipment storage.

Which Should You Buy?

  • Buy the deawater Blade if you own a compatible Honda mower (HRB215, HRR216, etc.) and need a sharp, affordable replacement blade to restore cutting quality. This is a simple, specific part for a specific task.
  • Buy the Battery Tender Junior if you have any 12V battery-powered equipment (lawn tractor, motorcycle, ATV, car) that sits unused for weeks or months. It’s a versatile tool that prevents dead batteries and extends their lifespan.
  • Buy both if you need a new blade for your Honda mower and want to keep the mower’s battery (or another 12V battery) maintained during off-season storage. They serve completely different purposes and complement each other well for lawn care.

Bottom line: These products aren’t alternatives—they’re complementary. The deawater blade is a niche replacement part for Honda mower owners, while the Battery Tender is a universal maintenance tool for any 12V battery. Choose based on your immediate need: a sharp blade or a charged battery.
