The 8 Best Lawn Mower Blades of 2026

A lawn mower is an engine, a deck, and a bar of steel spinning fast enough to shear grass — everything else is support staff. So the first time I finished mowing and saw ragged, whitish tips across the lawn, I didn't blame the mower. A dull blade tears grass instead of slicing it, and those torn tips brown off within a day while a clean cut heals over. Swapping one out is also the cheapest real improvement you can make to your lawn: usually less than a tank of gas and ten minutes with a wrench.

Over five months — about a full mowing season here — my team and I ran 16 blades across push mowers, self-propelled walk-behinds, and a couple of riding mowers. What first-time buyers tend to miss is that fit runs on part numbers more than deck width: a blade listed at 21 inches won't necessarily clear the spindle housing on your 21-inch deck. Profile matters too, since a heavy mulching blade leaves a different lawn than a high-lift one, and can drain a battery mower's runtime. Below are the ones worth bolting on.

Maxpower 331528B Mulching Blade Best Overall

Blade Type

View on Amazon

A replacement blade is only as good as its hole pattern. The Maxpower 331528B takes the bow-tie spindle used across a long list of 21-inch MTD, Cub Cadet, Troy-Bilt and Craftsman walk-behinds — the 742-0741, 942-0741 and CMXGZAM100067 family — which is more decks than anything else in this group covers. The outer holes measure 5/16 inch and sit 2.5 inches apart. If that doesn't match the blade on your mower, nothing else about this one matters.

What puts it first is coverage plus a genuinely quick swap. It goes on with a single bolt, and we like that nothing else changes — no adapter, no shimming, no second trip to the hardware store. At 1.6 pounds it's light enough to hold one-handed under a push mower, and the mulching profile leaves clippings fine enough that they settle into the lawn instead of sitting on top of it.

The edge is the part to know about. These arrive under a heavy coat of paint, and the cutting edge is inconsistent — some are ready to mow, others want a dozen passes with a mill file before the first cut. Ten minutes on the bench makes it a non-issue, but plan for it rather than being surprised by it. Buy this if you mulch a 21-inch MTD-family deck; if you bag every week, a high-lift blade moves more air.

Worth Noting

  • Single mulching blade, no high-lift bagging profile
Our Verdict

The blade we point most 21-inch MTD, Cub Cadet and Troy-Bilt owners to: the widest fitment here, a five-minute swap, and the lowest price of the picks.

Toro 59534P Recycler Blade Best Exact Fit for Toro Recycler

Toro 22" Recycler Mower Replacement Blade 59534P Display pack contains

22-inch Toro Recycler decks

Field Score 96/100
Thickness
0.1500 in.
Blade Type
Tooth mulcher
Center Hole
7/16 in.
Blade Length
21-11/16 in.
View on Amazon

If the mower in your garage is a 22-inch Toro Recycler, this is the blade to buy and there isn't much to debate. It's genuine Toro, it replaces 108-9764-03, and the 7/16-inch center hole lines up with no adapter and no guesswork. Fit is the entire point of a replacement blade, and this one gets it right.

The tooth-mulcher profile is what we like about it beyond the fit. Rather than a straight high-lift airfoil, the teeth keep clippings circulating under the deck for a second chop, and the practical result is less clumping on tall, wet spring grass. At 0.150 inch thick and 21-11/16 inches long it's a substantial piece of steel, and it goes on with the same single bolt as the original.

Toro has used more than one blade on the 22-inch Recycler over the years, so pull the number off your deck before ordering — 108-9764-03 is what this one replaces. For a Toro, the price sits close to the Maxpower and the fit is exact, which is a trade worth making.

Worth Noting

  • Fits Toro 22-inch Recycler decks only
Our Verdict

Genuine Toro steel, the right 7/16-inch center hole and a tooth-mulcher profile — the no-guesswork pick if a 22-inch Recycler is in your garage.

Set
2 blades

2-1/4 in.
Center Hole
6-point star
Blade Length
21-3/16 in.

What struck us lifting these out of the box is the weight — 3.4 pounds for the pair, in high-carbon steel. On a 42-inch rider that has been running thin stamped blades, that heft is most of the argument, because a heavy blade is a blade that comes back straight.

The 6-point star center and 21-3/16-inch length cover a long list of 42-inch MTD, Cub Cadet and Troy-Bilt decks, and they cross to Craftsman CMXGZAM110108 as well. Match the OEM number off your old blade — 942-04308, 942-04312, 742-04308 or 742-04312 — before you order. A 42-inch deck doesn't by itself tell you which hole you have.

Durability is where this pair earns its spot. A 42-inch rider finds roots, ant hills and the occasional rock, and this is the set in the group that shrugs those off; the high-carbon steel is thick enough that a bad hit damages the edge rather than folding the blade. The sharpening is the trade — these turn up with a working edge rather than a finished one, so plan a few minutes with a file on both before they go on. Do that and it's the strongest 42-inch value here.

Worth Noting

  • Does not fit 5-point-star Husqvarna or Poulan decks
Our Verdict

Our pick for 42-inch MTD-family riders: heavy high-carbon blades that shrug off roots and rocks, provided you touch up the edge before the first mow.

EGO AB2100 Replacement Blade Best for EGO Cordless Mowers

EGO POWER+ 21" Blade for Electric Lawn Mowers

EGO 21-inch cordless mowers

Field Score 94/100
Material
Factory-sharpened steel
Cut Width
21 in.
Blade Type
3-in-1 mulch, bag, side discharge
Item Weight
1.1 lb
View on Amazon

If you run an EGO, you're in a different position from everyone else on this list. The mower is a battery platform you keep for years and the blade is a wear part you swap on a schedule, so the only real question is whether the replacement is the right one. The AB2100 is, for the 21-inch models: LM2100, LM2100SP, LM2101, LM2102SP and LM2142SP.

It's a 3-in-1 blade, which matters more on a cordless mower than on a gas one. Mulching, bagging and side discharge all work off the same piece of steel, so changing how you handle clippings doesn't mean buying a second blade. It's factory sharpened at 1.1 pounds, and we appreciate that the direction of fit is marked on the blade itself — that alone saves the usual under-deck squinting.

Installation is one bolt, no adapter and no cross-referencing. Torque it, check it after the first mow, and you're done.

What settles it is the record behind it: this is the best-liked 21-inch blade in this group, and the one that needs no part-number archaeology at all. What you give up is weight. At 1.1 pounds the blade is light and pleasant to handle, but stony ground takes its toll on the edge sooner than a heavier blade will.

Worth Noting

  • Costs more than the gas-mower blades here
  • Fits only EGO's 21-inch models
Our Verdict

For EGO's 21-inch cordless mowers this is the blade to buy: genuine fit, three cutting modes and the strongest record of any 21-inch pick here.

Honda HRX Blade Kit Best Twin-Blade Set for Honda

Honda HRX Blade Kit

Honda HRS and HRR mowers

Field Score 93/100
Set
2 blades
Fits
Honda HRS and HRR
Cut Width
21 in.
Blade Type
Twin-blade mulching set
View on Amazon

Honda's HRX decks don't use one blade, they use two: a lower blade that cuts and an upper blade that recirculates what the first one throws, chopping it again before it drops. The kit supplies both halves — 72511-VH7-000 and 72531-VH7-000 — in genuine Honda steel, and it's the only set here built for that stacked arrangement.

Replacing both at once is the whole point, and this is the kit we reach for. Fit is exact on the HRS and HRR models, the parts are Honda's own, and the double cut is what produces the fine mulch these mowers are known for. Put one new blade in and leave the other worn, and the second chop never really happens.

One thing to know: they arrive with a working edge rather than a shaving edge. That's the spec, not a defect, and they cut cleanly from the first pass — but if you're expecting a razor out of the wrapper, you'll be reaching for a file. Check your deck before ordering, because a single-blade Honda takes a different part entirely.

Worth Noting

  • Pricier than a generic 21-inch blade
Our Verdict

Honda owners get both halves of the twin-blade system in one kit, correctly numbered and ready to bolt on — the only set here built for the double cut.

Ariens High-Lift Blade Set Best High-Lift Set for Zero-Turn Decks

Ariens 3 Pack Alloy Steel High-Lift 18-Inch Replacement Mower Blades

52-inch IKON XD decks

Field Score 92/100
Set
3 blades
Blade Width
2.25 in.
Center Hole
0.63 in.
Blade Length
18 in.
View on Amazon

A 52-inch deck doesn't run two blades, it runs three — 18-inchers, side by side, so the cut stays tight across a wide swath without a single blade long enough to flex. This is the full set: three blades, 2.25 inches wide, a 0.63-inch center hole, heat-treated alloy steel, made in the USA.

The high-lift profile is the reason to pick this over a plain replacement. The airfoil throws more air out from under the deck, which stands the grass up before the edge arrives and packs the bag harder. If you bag, or you want a striped finish, that's the difference you feel. If you mulch everything, this isn't the set.

Sharpness is what tips it for us. These come out of the wrapper with the best edge of any set here, and the balance is right from the first spin, which is not something every three-pack manages. The center hole seats properly on IKON XD and Edge spindles with no filing and no wobble.

What you're paying for is the set and the steel. The listing names both 52-inch and 42-inch decks, so confirm the blade part number for your deck before ordering — three wrong blades is an expensive mistake. For a 52-inch IKON XD that bags, this is the set.

Worth Noting

  • Most expensive set in this group
  • Fits Ariens IKON XD and Edge decks only
Our Verdict

Three sharp, heat-treated high-lift blades that seat exactly on IKON XD and Edge spindles — the set for bagging, where airflow is worth paying for.

This is the least expensive way onto a 21-inch MTD deck in this group, and it isn't a knockoff gamble. The Grasscool covers the TB110, TB130, TB230 and TB240 along with the MTD and Cub Cadet equivalents that take the 942-0741A, and its fit record is as clean as the top pick's. If price is the first thing you look at, this is the one to look at.

Where it beats the Maxpower is the edge — these come out of the wrapper sharp more consistently, so there's less bench time before the first mow. Where it gives ground is the record behind it, which is shorter and less settled, and we put it second for that reason alone. Both are single mulching blades within a few ounces of each other, so the choice comes down to whether you want the longer history or the better edge out of the box.

Worth Noting

  • Fitment limited to 21-inch MTD-family decks
Our Verdict

The value pick for 21-inch Troy-Bilt and MTD decks: same fitment as our top pick, a better edge out of the wrapper, and less money.

UDC Parts John Deere GY20850 Blades Best for 42-Inch John Deere Tractors

UDC Parts John Deere GY20850 Blades – GY20850 John Deere 42 Inch Mower Blades Replacement

Blade Width

Center Hole
7-point star
Blade Length
21-3/8 in.
View on Amazon

John Deere's 42-inch decks take three different blade numbers depending on the tractor and the year — GY20850, GX22151 and AM141033 — and the hole is a 7-point star. That's the confusion this set answers: one pair, cross-referenced to all three, for the D100, D110, D125, D130, LA115, LA125, E120, E130, S100 and Z225 tractors among others.

The dimensions are the interesting part. At 2-3/4 inches wide with 1 inch of air lift and a 5-7/16-inch cutting edge, these are a real mulching profile rather than a plain straight blade — the width and the lift are what keep clippings suspended under the deck long enough to be cut twice.

Installation is the usual single bolt per spindle, and the 7-point star seats without shimming or filing. There's no adapter and no ambiguity once you've matched the number, which is more than can be said for ordering a generic 42-inch blade and hoping.

We came away thinking of these as a value set, and thickness is where they give ground to the Maxpower pair. On a maintained lawn that costs you nothing. On rough ground with hidden stumps these can bend, and the heavier set is the safer buy there. If your Deere cuts a lawn rather than an acreage, they're a sensible buy.

Worth Noting

  • Fits only 7-point star John Deere 42-inch decks
Our Verdict

The straightforward buy for a 42-inch John Deere: three cross-referenced part numbers, a correct 7-point star, and a light build that suits a maintained lawn.

How We Tested Lawn Mower Blades

We started with part numbers. I pulled the numbers off the manuals for the mowers in my garage and my neighbor's shed, cross-checked them against every replacement number each listing claimed, and dropped anything that didn't match a deck size we could actually bolt it to. From there we compared price per blade, since two- and three-packs often beat a single on cost, and kept a mix of profiles — standard, mulching, and high-lift — noting which were stamped domestically.

All 16 blades went on by hand before a single engine started. I checked whether the center hole seated flat on the spindle, whether a star-shaped pattern lined up, and whether the tips cleared the housing, then ran the mower and listened for contact. Each one then mowed the same stretch of thick, slightly wet fescue, where I looked at whether the grass tips came out sheared clean or frayed white, whether clippings scattered or clumped into windrows, and whether the deck left stragglers behind.

Out of the box, I looked at the factory grind under a raking light and sliced a sheet of paper with each edge, then weighed every blade against the factory one it replaced, because a heavier blade changes how a mower — especially a battery one — carries itself. Five months of weekly mowing, plus a sandy half acre with two buried rocks and one badly overgrown back corner, gave me a read on durability: which edges rounded over first, which picked up nicks, and which started vibrating. The ones still cutting cleanly in August earned their spot here.

How to Choose Lawn Mower Blades

Match the part number, not the deck size

Two 42-inch decks from the same brand can take different blades, and the difference is usually the center hole: bow tie, 5-point star, 6-point star, 7-point star or a plain round hole. A blade with the wrong pattern either won't seat or will seat and then run out of balance, which is worse. Read the number stamped on the blade you're removing — 942-04308, 742-0741, GY20850 — and match it against the replacement's cross-reference list.

Deck width alone is never enough to go on. If the number has worn off, measure the center hole and the distance between the centers of the outer holes and compare that to the specifications. This is the step people skip, and it's the one that costs a return label.

Pick the blade type that matches how you handle clippings

Mulching blades recirculate clippings under the deck and cut them twice. High-lift blades move more air, standing the grass up before the edge reaches it and packing a bag harder. 3-in-1 blades do a passable job of all three. Buy for what you do most weeks, because the wrong profile shows up as clumping, a half-full bag or a ragged cut.

The EGO AB2100 is the flexible option in this group because all three modes work off one blade; the Ariens set is the specialist, built to lift and bag.

Weigh thickness against what your lawn throws at you

A heavier blade resists bending when you catch a root or a rock, and that is most of the difference between a set that lasts several seasons and one that doesn't. The trade is real: extra mass takes power to spin up, and a very heavy blade on a small deck is harder on the spindle.

For a 21-inch push mower, a blade around a pound and a half is normal. A 42-inch rider's pair runs over three pounds. Thickness is where inexpensive sets cut corners, so it's the first thing to check when two sets differ mainly on price.

Budget for an edge, and buy in sets

Most replacement blades ship with a working edge, not a razor, and paint or coating along the cutting edge is common. Ten minutes with a mill file before installation saves a ragged first cut and is the difference between a blade that mulches cleanly and one that tears grass tips brown.

Buy the number of blades the deck needs — two for a 42-inch, three for a 50- to 54-inch — and replace them as a set. One new blade beside a worn one cuts unevenly and runs out of balance. A spare set rotated in mid-season keeps you mowing while the dull one gets sharpened.

Frequently Asked Questions

Final Verdict

For most people the Maxpower 331528B is the answer. It covers the widest spread of 21-inch MTD, Cub Cadet, Troy-Bilt and Craftsman decks in this group, goes on with one bolt, and costs the least of any pick. Budget ten minutes with a file for the edge and it's one less thing to think about for the rest of the season.

If your deck isn't in that family, the pick changes with it. A 22-inch Toro Recycler gets an exact OEM fit in the 59534P; 42-inch MTD and Cub Cadet riders should take the heavier 561556B pair; EGO and Honda machines have genuine-part answers in the AB2100 and the HRX kit. Match the number on your deck and the decision makes itself.
