This review covers a 2-pack of 9-inch by 5/8-inch center hole, 3-side star edger blades sold as a heavy-duty craftsman lawn edger blade replacement for Craftsman and several other brands. It suits homeowners who own a compatible edger, want to restore clean edges without buying a new machine, and prefer a two-blade set for a spare. It is less suited to anyone whose edger uses a different arbor size or blade style, or to users who need a specialty blade for thick, woody roots. Before buying, confirm your mower-style edger’s blade diameter, center hole and tooth count, because fit is the single most common source of disappointment with replacement blades.
2 Pack 9" x 5/8" Center Hole 3-Side Edger Star Blade, Heavy Duty Lawn Edger Blades Replacement for Craftsman, Troy-Bilt, MTD, Replaces 781-0748, 781-0748-0637, 7185767, 490-105-M017, 40-009
Product Overview
The product is a two-pack of replacement edger blades listed as a direct fit for Craftsman, Troy-Bilt and MTD lawn edgers. The listing identifies the blade as a 9-inch, three-sided star design with a 5/8-inch center hole. The star shape is a common configuration on rotary edgers, where the blade spins at high speed and the tips slice soil and turf along a line. Compatibility is claimed through several part numbers, including 781-0748, 781-0748-0637, 7185767, 490-105-M017 and 40-009, which are the numbers a buyer would compare against the original blade or the owner’s manual.
The blade is marketed as heavy duty, which in this category generally refers to steel thickness and hardening rather than a specific alloy grade. Replacement blades of this type are usually sold to restore cutting performance after the original has dulled, chipped or bent. Because they are generic-equivalent parts rather than branded OEM components, the main question for most buyers is dimensional fit and whether the steel holds an edge through a season of use.

Pros & Cons
Pros
- Two blades in one pack, so a spare is on hand for a second edger or a quick swap.
- Lists multiple cross-referenced part numbers, which makes matching against an old blade easier.
- The 9-inch by 5/8-inch dimensions match a common rotary edger configuration.
- Star-shaped three-edge design is the standard geometry for clean vertical cuts along walks and beds.
- Replacement cost is typically well below buying a new edger, which keeps a working machine in service.
Cons
- Generic-equivalent blades are not manufacturer-branded, so fit depends entirely on matching dimensions.
- Steel grade and heat treatment are not detailed in the listing, so edge life is uncertain.
- Listed compatibility spans several brands, which means the buyer must verify the specific model.
- Not designed for heavy root cutting or metal-edging tasks that call for a different blade style.
Performance Analysis
Performance for a rotary edger blade comes down to three things: dimensional accuracy, edge retention and balance. Dimensional accuracy is the easiest to assess from the listing. A 9-inch diameter with a 5/8-inch center hole matches the geometry of many Craftsman and Troy-Bilt edgers, and the multiple part-number cross-references suggest the seller has mapped the blade against OEM numbers. If the blade seats flush on the drive shaft and the bolt tightens without the blade wobbling, the first major hurdle is cleared.
Edge retention is harder to judge from a listing alone. Owners of generic star blades commonly report that the first few trims are clean, with the edge softening over a season of cutting into compacted soil, roots and edging strips. Blades that are sharpened periodically with a file tend to hold up longer than those left to dull completely. Owners also frequently note that blades should be inspected after striking rocks or buried edging, since a small chip can unbalance the blade and cause vibration.
Balance is the third factor. Any replacement blade should spin true at operating speed. Owner feedback across generic edger blades tends to highlight vibration as the main sign of a poor fit or a warped blade, so checking runout and replacing the blade if it wobbles is a sensible precaution. Because the listing does not state the steel gauge or whether the blades are balanced at the factory, buyers should treat performance as a reasonable expectation rather than a guarantee.
Who Should Buy This Product?
This blade set is a good match for homeowners who already own a Craftsman, Troy-Bilt or MTD rotary edger with a 9-inch, 5/8-inch center-hole blade, and whose current blade has dulled, chipped or been lost. It also suits people who maintain several edgers, such as a household with two machines, and want a spare on the shelf. The two-pack format keeps the cost per blade reasonable for seasonal users who trim a few times a month.
Skip this product if your edger uses a different arbor or blade diameter, if you need a blade for heavy root cutting or metal edging strips, or if you require a manufacturer-branded part for warranty reasons. Owners of cordless or electric edgers should confirm that their machine takes a star-style blade of the same dimensions, since many use different mounting systems. If you are unsure about fit, measuring the old blade before ordering is the safest step.
Buying Guide
Before buying any craftsman lawn edger blade replacement, measure the blade diameter, check the center-hole size, and count the cutting edges. Compare these with the part number printed on your original blade or listed in the owner’s manual. Measuring is more reliable than trusting a generic compatibility list, because model years and sub-variants can differ.

Other things to weigh when shopping include steel quality, quantity, and whether you want a star blade or a different style. Some owners prefer a metal blade for tougher edging, and a detailed walkthrough is available in Metal Blade Lawn Edger: A Step-by-Step Guide to Clean Edges. If you want to compare several options side by side, 5 Best Lawn Edger Blades Replacement Options for Clean Edges (2026) covers a range of choices.
If you prefer a branded replacement from the same manufacturer as your edger, the Craftsman option below is worth considering. It is listed for the Craftsman edger line and may simplify fit questions, though it is a single blade rather than a multi-pack.

FAQ
Will this blade fit my Craftsman edger?
The listing names Craftsman among its compatible brands and cross-references several part numbers. Fit is most reliably confirmed by measuring the diameter and center hole of your current blade and checking the part number in your owner’s manual against the listing.
How do I know if I need a 9-inch blade?
Measure the blade tip to tip through the center. If the measurement is close to 9 inches and the center hole is 5/8 inch, the blade is likely a match. Measuring is more dependable than assuming, since some models use slightly different sizes.
Is a star blade better than a straight blade for edging?
Star-shaped blades with three cutting edges are the standard for rotary edgers making vertical cuts along walks and beds. Straight or specialty blades serve different tasks, so match the style to your machine and the job rather than assuming one is universally better.
How often should I replace an edger blade?
There is no fixed schedule. Replace the blade when it no longer cuts cleanly, when it chips or bends, or when the edger vibrates. Many users sharpen with a file between seasons before deciding on replacement.
Can I sharpen a replacement blade?
Yes, with a metal file kept at the factory bevel angle. Remove the blade, secure it, and file each edge evenly. Balance matters, so file all three edges the same amount and check that the blade spins true afterward.
Is it safe to install the blade myself?
Disconnect the spark plug wire or remove the battery before working on the blade, and wear gloves and eye protection. If you are uncomfortable with the process, a small-engine repair shop can install the blade. Consult a professional if the drive shaft or bolt appears damaged.
Are generic blades as durable as branded ones?
The listing does not state the steel grade or heat treatment, so durability cannot be confirmed from the description alone. Owners of generic blades often report good early performance, with edge life depending on usage, sharpening habits and the material being cut.
Final Verdict
This two-pack of 9-inch, 5/8-inch center-hole star blades is a practical craftsman lawn edger blade replacement for owners whose machine uses that dimension. The spare blade and the cross-referenced part numbers add real value, and the star geometry suits clean vertical edging. The main uncertainty is steel grade, which the listing does not specify, so verify fit carefully and inspect the blade for balance before first use. If your edger matches the listed dimensions, it is a sensible way to restore a clean edge without replacing the whole machine.
