This replacement blade suits owners of a Troy-Bilt TB554 or a closely related 9-inch gas edger who need to swap out a worn or damaged cutting blade. It makes sense for people who want a like-for-like part at a budget-friendly level. Skip it if your edger uses a different blade diameter, a different center hole, or a non-Troy-Bilt drive design, since fit is the main risk with any troy-bilt lawn edger tb554 blade replacement.
9inch 5/8 Hole Replacement Edger Attachment Blade for Troy-Bilt TB516EC TB554 TBE304 9-in Gas Lawn Edger /TBE515 TB515EC 9-in Lawn 4-Cycle Driveway Edger
Product Overview
This is a 9-inch edger attachment blade with a 5/8-inch center hole, listed as compatible with several Troy-Bilt edger models, including the TB554, TB516EC, TBE304, TBE515, and TB515EC. The listing describes it as a replacement for 9-inch gas edgers and a 4-cycle driveway edger. Because the part is sold as a direct replacement, the main decision is whether your model number appears in the compatibility list.
Key Features
- 9-inch cutting diameter, matching the blade size on compatible Troy-Bilt edgers
- 5/8-inch center hole for mounting on the listed models
- Listed compatibility with the TB554, TB516EC, TBE304, TBE515, and TB515EC
- Designed as a replacement for 9-inch gas lawn edgers and 4-cycle driveway edgers
Pros & Cons
Pros
- Lists the TB554 by name, which removes much of the guesswork for owners of that model
- Stated 9-inch diameter and 5/8-inch center hole match the original blade specification
- Straightforward swap that does not require modifying the edger housing
Cons
- Fit depends entirely on your exact model and blade spacing; check your manual before ordering
- Listing details beyond size, hole and compatibility are limited, so material and thickness need to be confirmed with the seller
Who Should Buy This Product?
Buy this blade if your Troy-Bilt edger is one of the listed models and the existing blade is bent, chipped, or no longer cutting cleanly. It is also a sensible choice if you want a direct replacement rather than a different style. If your edger is an older or unlisted model, measure the old blade’s diameter and hole size first, and compare the spacing of the mounting slots.
Alternatives
A two-pack of 9-inch center-hole 3-side star blades that lists Troy-Bilt among compatible brands makes sense if you want spares on hand or a heavier-duty option for frequent use.

FAQ
Will this blade fit my Troy-Bilt TB554?
The listing names the TB554 as a compatible model. Before ordering, compare the old blade’s diameter, center hole size, and mounting pattern with the listing, and confirm against your owner’s manual part list.
How do I know when the blade needs replacing?
Replace the blade if it is visibly bent, cracked, or chipped, or if it no longer cuts a clean edge and leaves the turf torn. Uneven wear can also cause vibration, which is a sign to stop and inspect the blade.
Should I disconnect the spark plug before replacing the blade?
Yes. Before any blade work on a gas edger, disconnect the spark plug wire and let the engine cool. If you are unsure about the procedure, consult a qualified small-engine repair professional.
Final Verdict
Recommended for TB554 owners who need a direct replacement
is a reasonable direct replacement for owners whose model appears in the compatibility list, with the TB554 named explicitly. Confirm the center hole and diameter against your old blade before buying. View on Amazon
