Overview

The Ryobi 16 Inch Replacement Blade for 40-Volt Lawn Mowers is a direct-fit cutting accessory designed specifically for Ryobi’s 40-volt cordless mower lineup, including models like the RY40180, RY401015, and others in the 16-inch deck family. At just over $12, it’s a budget-friendly way to restore your mower’s cutting performance without buying a whole new machine. This blade is best for homeowners who already own a compatible Ryobi 40-volt mower and need a sharp, reliable replacement to handle routine grass cutting on small to medium lawns.

Who Should Buy This

Ryobi 40-volt mower owners with dull or damaged blades – If your current blade is nicked, bent, or just plain dull after a season of use, this is the obvious, cost-effective fix. It’s a direct swap, no adapters or modifications needed.
Homeowners with lawns under 1/2 acre – The 16-inch cutting width is ideal for smaller yards where maneuverability matters more than raw speed. If you’re trimming a postage-stamp lot or a tight suburban patch, this blade keeps things simple.
DIY maintenance enthusiasts who sharpen their own blades – At this price, it’s almost cheaper to buy a new blade than to pay for professional sharpening. If you’d rather swap and go than mess with a file or grinder, this is your ticket.
Eco-conscious users who prefer cordless electric mowers – Ryobi’s 40-volt platform is quiet and emissions-free. This blade keeps that setup running smoothly, without the hassle of gas or extension cords.

Key Features Breakdown

16-inch cutting diameter – This isn’t a massive deck, but that’s the point. It fits Ryobi’s compact 40-volt mowers perfectly, letting you get close to fences and garden beds. For small lawns, it’s a sweet spot between coverage and agility.
Replacement blade for 40-volt Ryobi mowers – Specific compatibility matters here. This blade is engineered for Ryobi’s 40-volt line, not their 18-volt or gas models. Check your mower’s model number (like RY40180) before buying. The bolt pattern and center hole are precise, so installation is a five-minute job with a wrench.
Steel construction with a painted finish – It’s not a fancy stainless steel or hardened alloy, but for $12, it’s adequate. The paint helps resist rust during wet cutting seasons, though it will chip over time. Expect it to last one to two seasons of regular mowing before needing replacement.
Lightweight design – Weighing in at under a pound, this blade keeps the mower nimble. That’s a plus for battery efficiency—less mass means less strain on the motor, which can extend runtime on a single charge.
Universal fit within the 40-volt family – Ryobi uses a consistent mounting pattern across their 16-inch 40-volt mowers. That means you can stock up on a few blades and be ready for multiple seasons or even multiple mowers in the same lineup.

Pros

Perfect direct fit – No drilling, no washers, no guesswork. Line up the center hole, tighten the bolt, and you’re done. It’s as close to “plug and play” as a lawn mower blade gets.
Affordable price point – At $12.31, it’s cheaper than most sharpening services and far less than a new mower. You can replace it twice a season and still come out ahead.
Good for light to moderate grass – On well-maintained Bermuda, fescue, or ryegrass, this blade leaves a clean, even cut. It handles the typical suburban lawn without bogging down.
Low maintenance – No need to balance it (though you should check), no special tools required. A socket wrench and a block of wood to jam the blade are all you need for installation.
Quiet operation – Because it’s designed for an electric mower, the blade is balanced to run smoothly at lower RPMs. That means less vibration and noise compared to gas mower blades spinning at full tilt.
Readily available – Ryobi parts are everywhere. If you need a replacement fast, you can usually find this blade at big-box hardware stores or online retailers with quick shipping.

Cons

Not for heavy-duty or wet grass – This blade is thin and light. If you’re cutting thick, damp St. Augustine or letting your lawn get shaggy, expect clumping and a rougher cut. It’s no match for a mulching blade or a high-lift design.
Dulls faster than premium blades – The steel is basic. After 10-15 hours of use on sandy soil or weedy lawns, you’ll notice frayed grass tips. Plan to replace it every season, or more often if you mow frequently.
Limited to 16-inch decks – If you upgrade to a larger Ryobi mower down the road, this blade won’t fit. It’s strictly for the 16-inch models, so don’t stockpile too many unless you’re committed to that size.
No mulching or bagging enhancements – This is a standard flat blade. It doesn’t have curved wings or serrated edges for finer clippings. If you want a mulching kit or a high-lift bagging blade, you’ll need to look at aftermarket options.

Bottom Line

The Ryobi 16 Inch Replacement Blade is a no-brainer for anyone who owns a compatible 40-volt mower and needs a quick, cheap way to keep cutting. It won’t transform your mower into a commercial-grade beast, but it will restore factory-level performance for a fraction of the cost of a new machine. If you’ve got a small lawn, don’t mind swapping blades once or twice a year, and want to avoid the mess of sharpening, buy it. If you’re dealing with thick, wet grass or a larger yard, consider a more robust aftermarket blade instead. For the average homeowner, though, this is the right call.

Frequently Asked Questions

Q: Will this blade fit my Ryobi 40-volt mower model RY40180? A: Yes, it’s a direct fit for the RY40180, as well as the RY401015, RY401020, and other 16-inch 40-volt Ryobi mowers. Always double-check your model number on the mower’s underside or manual to be sure.

Q: How often should I replace this blade? A: For typical use on a 1/4-acre lawn mowed weekly, replace it once per season or after about 20 hours of cutting. If you hit rocks, roots, or sandy soil, inspect it monthly and swap it

How It Compares

Here is a head-to-head comparison of the Ryobi 16-Inch Replacement Blade (Mower A) and the Briggs & Stratton product (Mower B).

Important Note: Mower B is listed as a generic “Briggs & Stratton” product. Based on the price ($8.73) and the massive review count (22,608), this is almost certainly a replacement blade (likely a standard 21-inch or universal blade), not a complete lawn mower. Mower A is also a replacement blade. This comparison will proceed as a replacement blade vs. replacement blade comparison, not a full mower comparison.

Quick Verdict

Briggs & Stratton wins overall for most buyers due to its overwhelming user trust, lower price, and proven durability across thousands of reviews, while the Ryobi blade only wins for owners of Ryobi’s specific 40-volt 16-inch mower who need a perfect OEM fit.

Side-by-Side Comparison

Feature	Ryobi 16-Inch Blade (Mower A)	Briggs & Stratton Blade (Mower B)
Price	$12.31	$8.73
Power Source	Manual (replacement blade)	Manual (replacement blade)
Cutting Width	16 inches (fixed)	Typically 20–22 inches (universal fit)
Self-Propelled	No (blade only)	No (blade only)
Best Yard Size	Small yards (under ¼ acre)	Small to medium yards (up to ½ acre)
Warranty	Limited (parts only, varies)	Limited (parts only, varies)

Where Ryobi Wins

1. Perfect OEM Fit for Ryobi 40-Volt Mowers
The Ryobi blade is engineered specifically for Ryobi’s 16-inch 40-volt battery mowers. It matches the exact mounting hole pattern, center hole diameter, and blade length. No filing, drilling, or adapter rings are needed—it bolts right on.

2. Lighter Weight for Small Mowers
At 16 inches, this blade is shorter and lighter than most universal blades. This reduces strain on smaller mower motors (especially electric ones) and keeps the mower easier to maneuver in tight flower beds or along narrow paths.

3. Higher User Rating (4.3 stars) with 391 Reviews
While the review count is much lower than Briggs & Stratton, the Ryobi blade holds a solid 4.3-star average. Owners specifically praise its sharpness out of the box and zero-vibration performance on Ryobi mowers.

Where Briggs Wins

1. Massive User Trust and Proven Reliability
With 22,608 reviews and a 4.8-star average, the Briggs & Stratton blade has been tested by tens of thousands of homeowners. This is one of the most-reviewed lawn mower blades on the market, indicating consistent quality and sharpness.

2. Lower Price by $3.58
At $8.73, the Briggs blade costs about 29% less than the Ryobi. For a simple replacement part that gets dull over time, this savings adds up if you replace blades annually.

3. Universal Fit for Most Mowers (20–22 inches)
While the Ryobi is locked to 16-inch mowers, the Briggs & Stratton blade typically fits the vast majority of gas and electric mowers with 20- to 22-inch decks. It’s a true “one-size-fits-most” solution, making it easy to buy without worrying about brand compatibility.

Which Should You Buy?

Buy the Ryobi blade if:
You own a Ryobi 40-volt 16-inch mower and want the easiest, most precise replacement. The OEM fit eliminates guesswork and ensures optimal cutting performance. This is the best choice for owners of that specific model who value convenience over cost.

Buy the Briggs & Stratton blade if:
You own a standard 20- to 22-inch gas or electric mower (Honda, Toro, Craftsman, etc.) and want a proven, affordable blade that thousands of users trust. It’s also the better buy if you’re replacing blades on multiple mowers or just want the best value per dollar.

Buy neither if:
You need a complete lawn mower (not just a blade). Both products are replacement parts, not full mowers. If you’re shopping for a new mower, look at actual mower models instead of blades.

Here is a head-to-head comparison of these two products.

Quick Verdict

There is no winner—these are not comparable products; one is a replacement blade for a battery-powered mower (Ryobi) and the other is a set of inner tubes for pneumatic tires (AR-PRO), so the choice depends entirely on whether you need to cut grass or fix a flat tire.

Side-by-Side Comparison

Feature	Ryobi 16-Inch Replacement Blade	AR-PRO 2-Pack Inner Tubes
Price	$12.31	$12.79
Power Source	None (accessory for 40V mower)	None (accessory for gas/ride-on mower)
Cutting Width	16 inches	N/A (15x6.00-6" tire size)
Self-Propelled	No (blade only)	No (tire tube only)
Best Yard Size	Small to medium (compatible with 40V mowers)	Any size (fits 15-inch lawn mower tires)
Warranty	Not specified (likely 90 days to 1 year)	Not specified (typically 30-90 days)

Where Ryobi Wins

Direct Cutting Performance – This blade is designed specifically to cut grass. It fits Ryobi’s 40-volt 16-inch mowers (e.g., RY40180, RY40190) and provides a clean, mulching, or bagging cut. The AR-PRO tubes cannot cut anything.
Lightweight and Simple Maintenance – Replacing a blade takes minutes with a single wrench. It weighs less than a pound and requires no disassembly of wheels or tires. The AR-PRO tubes require removing the wheel, breaking the tire bead, and reinstalling—a much more labor-intensive job.
Direct OEM Fit – It’s a genuine Ryobi part with a 4.3-star rating from 391 reviews, meaning users confirm it fits perfectly and sharpens well. The AR-PRO tubes are generic replacements that may not match every tire’s inner diameter or valve stem length.

Where AR-PRO Wins

Massive User Base & Proven Reliability – With 20,211 reviews and a 4.3-star rating, the AR-PRO tubes are one of the most-reviewed lawn mower accessories on the market. Users consistently report they hold air, fit standard 15-inch tires, and prevent flats from thorns or punctures.
Versatility Across Equipment – These tubes fit not just lawn mowers but also wheelbarrows, ATVs, garden carts, and utility trailers. The Ryobi blade is locked into a single mower platform. If you own multiple machines, the AR-PRO set covers many needs.
Cost-Effective Flat Prevention – At $12.79 for two tubes (about $6.40 each), they are cheaper than replacing a whole tire or paying for a tire repair. A single Ryobi blade costs the same but offers no protection against the most common mower failure—a flat tire.

Which Should You Buy?

Buy Mower A (Ryobi Blade) if:
You own a Ryobi 40-volt 16-inch mower and your blade is dull, chipped, or bent. This is the exact replacement part you need for a sharp, efficient cut. It’s a no-brainer for restoring performance on small to medium lawns.

Buy Mower B (AR-PRO Inner Tubes) if:
You have a gas mower, riding mower, wheelbarrow, or ATV with 15x6.00-6 tires that keep going flat. This two-pack gives you a spare and costs almost the same as a single blade. It’s the smarter buy if you’re tired of patching tubes or replacing tires.

Buy Neither if:
You don’t need a replacement blade or tire tubes. If your mower runs fine and your tires hold air, save your money. If you need a blade for a non-Ryobi mower, look for a universal blade. If you need a tube for a different tire size (e.g., 13-inch or 20-inch), this set won’t fit.
