Best Replacement Blades for Push Lawn Mowers
As an Amazon Associate we earn from qualifying purchases.
Push mower replacement blades are sold for specific deck sizes and specific model numbers, so the safest first step is to find the part number printed on your old blade or in your owner’s manual. The blades in this roundup are all listed as push or walk-behind mower blades, and each listing names the deck size, part numbers or compatible models it covers. Read those details before you order, because a blade that is an inch off in length or has a different center hole will not mount correctly. This guide compares six replacement blades from the product pack, explains how to match them to your mower, and points out where a listing leaves a detail out.
Quick answer
- Match the blade to your deck size and model number first. The listings name decks from 20 to 22 inches and list specific Troy-Bilt, Hyper Tough, Greenworks and Husqvarna models.
- Check the part number against the number printed on your current blade. Several listings include a list of replacement numbers rather than one number.
- Look at the center hole and the blade dimensions. The listings give the length, width, thickness and center hole shape for most blades.
- Buy a two-pack when the listing offers one, so you have a spare when the current blade needs sharpening or replacing.
How to choose a replacement blade for your push mower
Start with the deck. A push mower blade is cut to a particular length, and the listing gives that figure in inches or millimeters. The Grasscool Toro blade is listed at 21-5/8 inches long for a 22-inch deck. The UDC Parts and Wadoy blades are both listed at 20 inches for a Hyper Tough 20-inch deck. The ZALANA blade is listed at 21 inches for Troy-Bilt and Craftsman decks. The Greenworks blade is sized for a 20-inch Greenworks mower, and the listing says it is about one inch shorter than the deck size so it clears the deck edge. Use your deck measurement and your model number together rather than the deck size alone.
Next, look at the center hole. The Grasscool listing describes a circle center hole, the UDC Parts blade lists an oval hole measuring 1 inch by 3/4 inch, and the ZALANA listing describes a bow-tie hole. A blade with the wrong center hole will not sit on the spindle. Remove the bolt from your current blade, measure the hole, and compare it with the listing before you buy.
Finally, check the blade type. Some listings are mulching blades, such as the Grasscool and ZALANA blades. The Husqvarna listing describes a 4-in-1 blade for bagging, mulching and discharge. The UDC Parts, Wadoy and Greenworks listings do not give the same type detail in the pack, so check your current blade’s shape against the photo before you order.
Materials and build
The listings describe different materials, and the pack does not give the same level of detail for each one. The Husqvarna listing says the blade is forged with hardened steel and is an original factory part. The Greenworks listing says the blades are heat-treated steel and can be removed for sharpening and replacement. The Wadoy listing describes a powder-coat finish that helps prevent rust and says tungsten carbide is fused to the cutting edge. The Wadoy listing also says the part is a non-original aftermarket blade and was not made by Hyper Tough. If you want an original part, the Husqvarna and Hyper Tough compatible listings are the ones to compare. If you want a lower-cost aftermarket blade, the Wadoy and UDC Parts listings are the ones to read closely.
The Grasscool listing includes a note that the blade may have paint on it when it arrives. The listing says the paint protects the blade in shipping and wears off after a few minutes of mowing, so the paint does not need to be removed before use. The same listing also asks buyers to match the replacement number to the model, not only the compatible model number.
Roundup: six replacement blades from the pack
Grasscool 22-inch Toro Recycler mulching blade
This blade is listed for a 22-inch deck on a Toro Recycler walk-behind mower. The listing gives a blade length of 21-5/8 inches, a width of 2-1/4 inches, a thickness of 5/32 inch and an air lift of 7/8 inch. It names the part numbers 131-4547-03, 108-9764-03, 104-8697-03 and 59534p, and the listing says the blade is a toothed mulching blade with a circle center hole. Choose this one if your Toro deck is 22 inches and your current blade matches those dimensions. Because the listing gives several part numbers, compare each one with the number on your blade before you buy.
UDC Parts 2105300125A blades, 2-pack for Hyper Tough 20-inch mowers
This two-pack is listed as a replacement for the Hyper Tough 2105300125A part and the Daye 2105300125A and 101000001 parts. The listing says the blades fit Hyper Tough E300 series 20-inch push mowers, including models MNA152505, MNA152516 and MNA152701. The listed dimensions are 20 inches long, 2-1/4 inches wide, a 1-inch by 3/4-inch oval center hole, a 1-1/32-inch air lift and a cutting edge length of 6-37/64 inches. Choose this pack if you own one of the named Hyper Tough or Daye models and want two blades in the box.
Wadoy 2105300125A 20-inch blades, 2-pack
The Wadoy pack covers the same 2105300125A part number and lists the same two Hyper Tough models, MNA152505 and MNA152701. The listing describes a powder-coat finish that helps prevent rust, an extended cutting surface, and tungsten carbide fused to the cutting edge. It also says the blade is a non-original aftermarket part. The listing asks buyers to check the part number printed on the blade before ordering, which is a good habit with any aftermarket blade. Choose this one if you want the same size and model match at a different brand, and you accept that it is not the original part.
ZALANA 21-inch mulching blades for Troy-Bilt and Craftsman decks
This ZALANA two-pack lists the 942-0741A part and several related numbers, including 942-0741, 742-0741, 742-0741A and CC-742-0741. The listing gives a blade length of 21 inches, a width of 2-1/4 inches, a thickness of 0.126 inch and a bow-tie center hole. It names Troy-Bilt models such as the TB110, TB130, TB210 and TB230, and lists Tuff-Cut and Pro-Cut models as compatible. It also lists Craftsman compatibility. Choose this set if your mower is one of the named Troy-Bilt or Craftsman models with a bow-tie center hole.
Greenworks blade set for the 25302 twin force mower
This listing is a set of right and left blades for a Greenworks 20-inch mower, and the title names model 25302. The listing describes the blade as genuine Greenworks, heat-treated steel for a sharp cut, and removable for sharpening. The blade length is listed at 9.5 inches. The listing also says the blade is about one inch shorter than the deck size so it clears the deck edge. Choose this set if you own a Greenworks 25302 or a 20-inch Greenworks mower that uses this blade.
Husqvarna 22-inch multipurpose push mower blade
This is a 22-inch Husqvarna blade that the listing says replaces OEM part number 5810452-01. It is listed for single-start BBC models and is described as forged with hardened steel. The listing describes 4-in-1 performance for bagging, mulching and side discharge, with a high-lift design for suction. Because it is an original factory part according to the listing, it is the option to compare if you want to stay with the mower maker’s own blade. Confirm the BBC model number on your mower before ordering.
Deep look: the Husqvarna blade as the reference point
If you want one blade to judge the others against, the Husqvarna listing gives the clearest set of facts. It names the OEM number it replaces, the model family it fits, the steel it is forged from, and the cutting modes it supports. Those details let you check your current blade against the listing in a few minutes. The listing does not give a length in the pack, so measure your old blade from tip to tip and compare it with your mower’s deck size before ordering. The same approach works for the other five blades: match the part number first, then the length, then the center hole.
Use the listing wording carefully. The Husqvarna listing describes an original part, while the Wadoy listing describes an aftermarket part. Both can work when the number matches, but they are different purchase decisions. Original parts are the simpler choice when you want the mower maker’s fit. Aftermarket parts can cost less, but the number match becomes your main check.
Mistakes to avoid when buying replacement blades
- Buying by deck size alone. Two 20-inch mowers can use different blades, so check the model number.
- Ignoring the center hole. A blade that does not fit the spindle is useless, even if the length is right.
- Assuming a blade is an original part. The Wadoy listing says it is aftermarket, and the Husqvarna listing says it is original.
- Skipping the balance check. The pack does not describe a balancing procedure, so use your owner’s manual for the blade removal and reinstall steps.
- Mixing left and right blades on a set. The Greenworks listing sells a right and left set, so keep the pair together.

Where a length or model is not stated in the listing, the table says so. Check the listing before you buy.
FAQ
How do I find the right replacement blade part number?
Look for the part number printed on the blade itself, or in your mower’s owner’s manual. Compare that number with the part numbers listed in each product. Several listings name more than one number, so a match with any listed number is a good sign, but compare the full dimensions too.
Can I use an aftermarket blade instead of an original one?
Yes, when the listing names your model and the part number matches. The Wadoy listing describes itself as a non-original aftermarket part. The Husqvarna listing describes an original factory part. Both are valid choices, but the number and fit checks matter more with an aftermarket blade.
Why do the blade lengths differ for the same mower?
Blade length depends on the deck and the mounting style. The Greenworks listing says its blade is about an inch shorter than the deck size. The Grasscool blade is 21-5/8 inches for a 22-inch deck. Match the length to your own blade rather than to the deck name alone.
Do I need a two-pack?
A two-pack gives you a spare, which is useful because blades wear and need sharpening or replacement. The UDC Parts and Wadoy listings are both two-packs. A single blade may be enough if you only need to replace one damaged blade.
Should I remove the paint on a new blade?
The Grasscool listing says you do not need to remove the paint before use. It says the paint protects the blade during shipping and wears off after a few minutes of mowing. Check the listing for the same guidance on any other blade before you decide.
What should I check before buying a blade for a Husqvarna mower?
Confirm that your mower is a single-start BBC model, since the listing names that model family. Then check the OEM number 5810452-01 against your old blade. The listing does not state the blade length in the pack, so measure your current blade before ordering.
Bottom line
Buy the replacement blade that matches your part number, deck size and center hole, in that order. If you want an original part, the Husqvarna and Greenworks listings name the mower and number they fit. If you want a spare, the UDC Parts, Wadoy and ZALANA listings sell two-packs. Measure your old blade, check the number, and only then add it to your cart.
