Oregon Gator G3 Mulching Lawn Mower Blade
A universal mulching replacement blade with a superior cutting edge and a limited lifetime warranty.
Who it's for: owners of standard mowers wanting a mulching blade with a stated warranty.
Who should skip it: anyone needing a stated width or a blade for a listed OEM fit, since this listing states neither.
Read the full review
Oregon lists this Gator G3 blade as a universal mulching replacement with a superior cutting edge, a 1 inch round center hole and a 26-point certification of manufacturing quality and control, made in the USA with a limited lifetime warranty. The listing contradicts itself on length: the title says 20 inches while the bullets and spec size say 19-3/4 inches, so this roundup follows the bullets at 19-3/4 inches. The spec table also lists the material as Plastic and the weight as 0.01 ounces, both of which read as data errors for a mower blade.
Pros
- 19-3/4 inch length fits many residential and commercial mowers
- Mulching design with a superior cutting edge
- 26-point certification of manufacturing quality and control
- Limited lifetime warranty included
Cons
- Title says 20 inches while the bullets say 19-3/4 inches
- Spec table lists the material as Plastic, which reads oddly for a blade
- Spec table weight of 0.01 ounces reads as a data error
- Width is not stated in the listing
Fismiuta 21 Inch Mulching Lawn Mower Blade for Craftsman and Husqvarna
A forged 40MnB boron steel medium-lift blade for 21-inch Craftsman and Husqvarna decks.
Who it's for: owners of listed 21-inch Craftsman and Husqvarna decks wanting a sturdy mulching blade.
Who should skip it: anyone outside the listed fitment or wanting a stated warranty, since this listing gives neither.
Read the full review
Fismiuta lists this blade as a forged 40MnB boron steel medium-lift blade for 21-inch Craftsman and Husqvarna decks, with full-body heat treatment, digital dynamic balancing and a heavy-duty powder coating. The maker claims 35% higher impact resistance over low-cost carbon steel replacements; that figure is the maker's claim, reported here as stated. The bullets and spec table agree on the 21 inch cutting width, so there is no size contradiction to resolve.
Pros
- Forged 40MnB boron steel with full-body heat treatment
- Maker claims 35% higher impact resistance
- Medium-lift design for mulching, bagging and side discharge
- Digital dynamic balancing for reduced vibration
Cons
- No warranty term is stated
- Fits only the listed 21-inch Craftsman and Husqvarna models
- No width or thickness is stated
- No center hole diameter is stated, only that it is a circle
Yard Force 21-Inch 3N1 Mulching Lawn Mower Blade
A genuine OEM 21-inch 3-in-1 blade for Yard Force YF22-3N1SP mowers.
Who it's for: owners of the listed Yard Force mowers wanting an exact OEM fit.
Who should skip it: anyone with a different mower or wanting a stated warranty, since this blade fits only the listed models and states none.
Read the full review
Yard Force lists this blade as a genuine OEM replacement, part 1253556001, for YF22-3N1SP, YF22-3N1SP-SC and YF22-3N1SPVS-SC self-propelled mowers, in high-strength stamped steel with a dual-edge mulching design. The listing contradicts itself twice: the bullets say 0.14 in thickness and 2 lbs, while the spec table says 0.06 in and 1.5 pounds, so this roundup follows the bullets. The 21 inch length and 2.25 inch width agree across bullets and spec table.
Pros
- Genuine OEM part 1253556001 for YF22-3N1SP mowers
- 3-in-1 design for bagging, mulching and side discharge
- High-strength stamped steel construction
- Dual-edge mulching blade design
Cons
- Bullets say 0.14 in thickness while the spec table says 0.06 in
- Bullets say 2 lbs while the spec table says 1.5 pounds
- No warranty term is stated
- Fits only the listed Yard Force models
MaxPower 16 Inch Power Rake Dethatcher Lawn Mower Blade
A 16-inch universal power rake and dethatcher blade with reducing washers for many mowers.
Who it's for: zoysia lawns needing seasonal dethatching alongside a regular mowing blade.
Who should skip it: anyone wanting a daily mowing blade, since this is a power rake blade for thatch work.
Read the full review
MaxPower lists this blade as a 16 inch universal power rake and dethatcher blade, 2-1/4 in wide with a 1 inch center hole, made in the USA, including a cover washer and 6 reducing washers in sizes from 3/8 in to 3/16 in. It is a dethatching tool rather than a standard mowing blade, which matters on zoysia lawns where thatch builds up in dense turf. The bullets and spec table agree on the 16 inch length, so there is no size contradiction to resolve.
Pros
- 16-inch universal fit with a 1-inch center hole
- Cover washer and 6 reducing washers included
- Made in the USA to meet or exceed OEM specifications
- Power rake design for dethatching work
Cons
- No warranty term is stated
- A dethatcher blade, not a standard mowing blade for daily cuts
- No material is stated
- Mulching, bagging and side discharge are not stated for this blade

How to choose the best lawn mower blade for zoysia grass
Match length and center hole to your mower
Blade lengths here run from 16 in on the Maxpower to 21 in on the Yard Force and the Fismiuta, with the Oregon at 19-3/4 in. Measure your deck before ordering: a blade that is too long will not fit, and one that is too short leaves uncut strips. Center holes are 1 in on the Maxpower, the Oregon and the Yard Force, while the Fismiuta lists a circle hole without a diameter. See our blades for 21 inch decks if your deck measures 21 in.
Mulching, dethatching or both
The Oregon and the Yard Force are mulching blades, and the Fismiuta covers mulching, bagging and side discharge with a medium-lift design. The Maxpower is a different tool: a power rake and dethatcher blade for pulling thatch out of dense turf like zoysia. If your zoysia lawn has a thick thatch layer, the dethatcher earns its place alongside a mowing blade; it does not replace one for weekly cuts. See our blades for mulching for more mulching options.
Steel, certification and warranty
Materials here range from high-strength stamped steel on the Yard Force to forged 40MnB boron steel on the Fismiuta, while the Oregon leans on a 26-point certification of manufacturing quality. The Fismiuta maker claims 35% higher impact resistance from its boron steel and heat treatment; treat that as the maker’s claim, not a measured result. Only the Oregon states a warranty, a limited lifetime warranty, while the other 3 state none.
Fit, washers and storage
Check the compatibility list before ordering an OEM-style blade: the Yard Force fits only listed YF22-3N1SP mowers, and the Fismiuta fits listed 21-inch Craftsman and Husqvarna decks. The Maxpower includes a cover washer and 6 reducing washers in sizes from 3/8 in to 3/16 in, which helps it fit more mowers. Keep spare washers with the blade so a swap does not stall on a missing part.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- On flat zoysia lawns, any of these lengths works if it matches the deck; measure the deck first.
- Where thatch has built up, pair a mowing blade with the Maxpower dethatcher blade for seasonal cleanup.
- Around trees and beds, check the blade’s fit list rather than assuming a universal blade fits.
- Store the Maxpower reducing washers with the blade so the right size is at hand.
The Acre Score explained
The Acre Score weighs performance (cutting design and fit), build (material and construction), value, safety and warranty. For a blade, safety means a stated manufacturing certification or safety standard; only the Oregon names one, a 26-point certification. Only the Oregon states a warranty term, a limited lifetime warranty. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Oregon Gator G3 | 9.7 | 30 | 21 | 21 | n/a | 4 |
| Fismiuta 406712 | 9.6 | 30 | 22 | 20 | n/a | 0 |
| Yard Force 3N1 Blade | 9.6 | 29 | 21 | 20 | n/a | 0 |
| Maxpower Dethatcher | 9.5 | 27 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
What length blade do I need for my mower?
Match the blade to your deck: 16 in on the Maxpower, 19-3/4 in on the Oregon, and 21 in on the Yard Force and the Fismiuta. Measure the deck before ordering, since a blade that is too long will not fit.
Does a dethatcher blade replace a mowing blade?
No. The Maxpower is a power rake and dethatcher blade for pulling thatch from dense turf, while the Oregon, Yard Force and Fismiuta are mowing blades for regular cuts. Use the dethatcher for seasonal cleanup, not weekly mowing.
Which of these blades states a warranty?
Only the Oregon, which includes a limited lifetime warranty. The Maxpower, Yard Force and Fismiuta state no warranty term.
Will the Yard Force blade fit my mower?
Only if your mower is one of the listed models: YF22-3N1SP, YF22-3N1SP-SC or YF22-3N1SPVS-SC. Check the model number before ordering.
What center hole do these blades use?
The Maxpower, Oregon and Yard Force list a 1 in center hole. The Fismiuta lists a circle center hole without a stated diameter, so check its compatibility list.
