You probably own a walk-behind edger or a personal watercraft with the LE720 badge somewhere on the housing, and you just need the right cutter or starter relay to bring it back from the shed. Parts shopping for older machines tends to feel like a scavenger hunt, so I pulled together eight options that fit the LE720 platform and grouped them by what they actually do. The picks below cover hardened steel edger blades, replacement guards, and starter solenoids, so you can match the part to the repair instead of guessing at a listing.

The Picks, Examined More Closely
Walk-behind edgers earn their keep when the blade stays sharp, and once yours rounds off, the unit starts tearing grass instead of slicing it. This twin-pack targets MTD-built LE720 walk-behind edgers from model years 2000 through 2020, so older machines still get supported without forcing a retrofit.
The blades use a heat-treated steel body (a process where the metal is heated and cooled rapidly to boost surface hardness), which holds up well against sandy soil and the occasional buried root. Owners with mid-size suburban lots, where edging runs take 20 to 40 minutes at a stretch, should find the wear rate reasonable across a full season.
Positive Points
- Two blades ship in each pack, so you keep a spare on the shelf rather than scrambling mid-project.
- Heat-treated steel resists dulling in dry, sandy soils that chew through softer stamped blades.
- Standard 1-inch center hole drops onto most LE720-era edger shafts without adapter hardware.
- Cuts cleanly along driveway and walkway edges, leaving a tidy vertical line with one slow pass.
Things To Consider
- Only fits MTD-branded units, so Troy-Bilt or CRAFTSMAN owners (covered elsewhere in this list) need a different match.
- Hardened steel can chip on hidden rocks, which is normal wear rather than a defect.
Feature Snapshot
Who Should Grab It
MTD LE720 owners who edge along concrete drives and sidewalks a few times per month and want a season’s worth of cutting ahead.
Consider Something Else When
Troy-Bilt-branded units call for the 2Pcs Edger Blade 613223 E3100 for Troy-Bilt LE720 2000–2020 instead, since blade fit varies by housing brand.
Troy-Bilt walk-behind edgers share a lot of hardware with their MTD cousins, but the blade fitment is brand-specific enough that swapping across the fence rarely lines up. This twin-pack is built around the Troy-Bilt LE720 chassis from 2000 through 2020, giving those machines their own dedicated cutter.
The hardened steel construction handles weekly edging sessions without the edge folding over, and the blade geometry keeps the cut vertical against hard turf edges. Yard crews and homeowners with established landscaping benefit most, since the cut stays clean even after the grass has thickened up in late summer.
Positive Takeaways
- Twin-pack format means fewer emergency runs to the hardware store mid-project.
- Heat treatment supports a longer interval between swaps in rocky or root-heavy beds.
- 1-inch center hole matches existing Troy-Bilt LE720 hardware for tool-free mounting.
Honest Caveats
- Not interchangeable with the MTD version, so cross-brand shops need to order carefully.
- Hardened cutters can throw a spark on concrete strikes, which is normal but startling the first time.
Best Suited To
Troy-Bilt LE720 owners running regular curb-and-walkway edging through spring and summer who want blades that survive contact with gravel borders.
Look Elsewhere When
Owners of CRAFTSMAN TrimmerPlus stick edgers should grab the 2×7.75-in Edger Blade Replacement for CRAFTSMAN TrimmerPlus LE720 instead, since stick edgers use a smaller blade profile.
TrimmerPlus attachments turn a string trimmer into an edger with a quick swap, and the LE720 module has been around long enough that older units still show up in sheds. This pair of blades covers TrimmerPlus LE720 attachments from 2000 through 2026, which is unusually wide for a replacement cutter.
The hardened steel keeps the edge stable through weekly curb work, and the twin-pack leaves you with a backup once the leading blade finally dulls. People who treat edging as a Saturday chore rather than a daily task get the most value here, since the wear pattern stretches out comfortably between swaps.
Useful Touches
- Model-year range stretches across 26 seasons of TrimmerPlus LE720 attachments.
- Heat-treated steel construction survives weekly curb edging across a full growing season.
- Standard 1-inch center hole fits the TrimmerPlus spindle without extra hardware.
Points To Note
- Hardened steel needs a steady hand around buried irrigation flags, since contact can nick the edge.
- Two blades in the pack is plenty for a stick edger, but walk-behind owners may burn through both quicker.
The Right Fit
TrimmerPlus attachment users who edge along driveways a few times per month and want blades that survive multiple seasons before replacement.
A Better Fit Elsewhere
CRAFTSMAN stick edger owners get a better match from the 2×7.75-in Edger Blade Replacement for CRAFTSMAN TrimmerPlus LE720, which is sized for that specific shaft.
A starter solenoid relay (the small switch that sends battery current to the starter motor when you turn the key) is one of those parts you only think about when the engine refuses to crank. This relay fits Sea-Doo-era GTI LE720 personal watercraft alongside the GS720, GTI720, and GTS720 models, with cross-reference part numbers 278001376, 278002347, and 278001766 covering common replacements.
Direct swap design keeps the swap straightforward for anyone with basic hand tools, and the housing uses durable materials that should hold up against marine humidity. Garage mechanics restoring older two-stroke watercraft for weekend lake use get the most mileage from this pick.
Well-Handled Touches
- Cross-references multiple OEM numbers, so one purchase covers several common fault codes.
- Direct-fit replacement drops into the original mounting bracket without rewiring.
- Solid housing construction helps the relay resist vibration during rough-water operation.
Worth Bearing In Mind
- Verify the OEM number on your existing relay before ordering, since similar-looking units use different internals.
- Saltwater riders should still rinse the electrical bay after each outing, since no relay is fully corrosion-proof.
Made For
Backyard marine mechanics troubleshooting a no-crank condition on a GTI LE720 or sibling Sea-Doo model from the early 2000s.
Skip It When
Riders running newer four-stroke Sea-Doo models with different OEM numbers should grab the 1Pc Motorcycle Starter for GS720 GTI720 LE720 GTS720, which targets a broader cross-section of vintage hulls.
Personal watercraft that spend summers on a lake eat electrical parts for breakfast, especially the starter relay sitting just forward of the battery box. This starter unit covers the GS720, GTI720, LE720, and GTS720 family, with a waterproof and rust-resistant shell designed for humid marine bays.
The integrated electromagnetic mechanism buffers vibration during rough-water operation, which matters on older hulls where engine mounts have softened. Boathouse owners who launch every weekend get a relay that survives splash zones better than a generic unit pulled off a shelf.
The Case For It
- Waterproof shell reduces corrosion risk in splash-prone engine bays.
- Vibration-buffered internals help the relay survive chop and rough-water riding.
- Direct-fit design swaps onto the original bracket without rewiring or shimming.
- Accessible terminal layout makes routine voltage checks easier during preseason service.
Some Limits To Know
- Heavier shell adds a small amount of weight compared to a stripped-down OE unit.
- Still needs periodic inspection since marine environments never fully stop corrosion.
Who Will Love This
Lake-country riders launching through saltwater or brackish marinas where standard relays corrode within two seasons.
Reach For A Different Pick When
Budget-focused owners with a clean freshwater trailered boat should consider the 1Pc Motorcycle Starter for GS720 GTI720 LE720 GTS720 instead, which keeps things simpler without the marine-rated shell.
Sometimes the easiest repair is the one that needs the fewest adapters, and this starter relay drops onto the existing wiring harness without any modification. It covers the same GS720, GTI720, LE720, and GTS720 family as the other relays in this list, with cross-reference numbers 278001376 and 278002347.
Reliable circuit connection matters most when the hull has been sitting through winter, and the strong construction handles vibration during normal riding. Weekend boaters who want a same-afternoon fix rather than a long parts hunt get the most value from this straightforward replacement.
What Stands Out
- Direct-fit design connects to existing wiring without cutting or splicing.
- Sturdy construction holds up under routine vibration across a full riding season.
- Supports stable power flow to the starter motor, which matters on cold mornings.
Trade-Offs To Consider
- No specialized waterproof shell, so saltwater riders may see shorter service life than the marine-rated relay above.
- Cross-reference list covers several OEM numbers, so double-check before clicking through to the listing.
Perfect Match For
Trailered-boat owners who want a no-fuss relay swap during preseason commissioning.
Swap It Out When
Saltwater riders get better protection from the 1Pc Motorcycle Starter for GS720 GTI720 LE720 GTS720 with the waterproof shell upgrade.
Stick edgers live a tougher life than walk-behinds because the blade cuts at whatever angle you hold the shaft, and curbside rocks shorten blade life fast. This replacement set runs 7.75 inches by 1 inch, sized for the CRAFTSMAN-branded TrimmerPlus LE720 stick edger and similar PAS2601-series attachments.
The shorter blade profile fits inside the stock guard without binding, and the steel construction handles weekly curb work without folding. Homeowners with established walks and curbs who edge every couple of weeks benefit most from this direct-fit replacement.
Everyday Wins
- Sized specifically for CRAFTSMAN TrimmerPlus LE720 attachments, no adapter required.
- Steel construction handles curb contact without folding over.
- Two-blade pack covers a season of regular edging on a standard residential lot.
Potential Sticking Points
- Shorter blade profile moves through thick grass more slowly than a longer walk-behind blade.
- Stick edger shafts put more lateral force on the cutter, so blade life is shorter than on a wheeled unit.

Where A Sibling Pick Shines
Walk-behind edger owners get better results from the 2Pcs Edger Blade 613223 E3100 for MTD LE720 2000–2020, which uses a longer blade profile for deeper curb cuts.
A bent blade guard is one of those things people ignore until a thrown rock cracks a window or chips a tooth. This combo part ships a fresh 8-inch by 2-inch edger blade plus a replacement guard, sized for the standard 1-inch center hole shared across MTD, CRAFTSMAN, Cub-Cadet, and Troy-Bilt trimmer platforms.
The matching guard restores proper debris deflection, which matters most in yards with gravel mulch beds where thrown stones travel surprisingly far. Property owners who have ignored a dented guard for too long get both fixes in a single order.
Where It Excels
- Combo pack delivers a fresh blade and matching guard together.
- Cross-brand fitment covers MTD, CRAFTSMAN, Cub-Cadet, and Troy-Bilt trimmer models.
- Standard 1-inch center hole matches the LE720 spindle alongside comparable units.
Where It Is Less Suited
- Heavier combined package costs more to ship than a blade-only replacement.
- Guard may not match the OEM color on every trimmer model, which is purely cosmetic.
Built With In Mind
Homeowners with gravel-edged beds who have put off guard replacement and want both parts in one shipping box.
Another Choice May Suit
Shed-maintenance crews who already replaced the guard should grab the 2Pcs Edger Blade 613223 E3100 for Troy-Bilt LE720 2000–2020 for a blade-only refresh.
Matching Parts to Your LE720 Machine
Edger blades and starter relays solve completely different problems, so the first move is identifying which side of the platform your LE720 unit falls on. Walk-behind edgers and TrimmerPlus stick attachments both use the LE720 name, but their blade sizes, mounting hardware, and compatible model years differ enough that a single listing rarely covers both. Personal watercraft branded LE720 sit in a totally separate category and need a marine-rated electrical part rather than a steel cutter.
For edger blades, the deciding factor is usually brand and model year. MTD, Troy-Bilt, CRAFTSMAN, and Cub-Cadet all shared the LE720 platform through various corporate relationships, so cross-checking the housing badge before ordering saves a return trip. Walk-behind owners running mid-size suburban lots benefit from longer 8-inch blades that cut deeper at the curb, while stick edger users need shorter 7.75-inch blades that fit inside the stock guard.
For starter relays, the key spec is the OEM cross-reference number printed on the original part. Numbers like 278001376, 278002347, and 278001766 each map to specific model years, and using the wrong relay can leave you with a no-crank condition that mimics the original problem. Saltwater and brackish riders get more value from a waterproof shell, while freshwater trailered boats do fine with a standard direct-fit relay.
What Most Shoppers Overlook
Common Shopping Slip Ups
The biggest mistake is assuming all LE720 parts interchange across brands. MTD and Troy-Bilt share corporate ownership but their edger housings accept different blade geometries, so ordering by brand badge rather than part number leads to returns.
Second, ignoring the model-year range on the listing catches people with mid-2000s machines who buy a 2010-and-newer part. The LE720 platform ran across multiple decades, and blade profiles shifted slightly between generations.
Why Top Tier Costs More
Marine-rated relays cost more because the waterproof shell and sealed terminals add material and assembly steps. That premium matters for saltwater riders where standard relays corrode within two seasons, but freshwater boaters rarely see a real-world benefit from the upgraded housing.
Combo blade-and-guard packs cost more than blade-only replacements for obvious shipping reasons, but the value shows up when a dented guard has been hiding behind a working blade. Replacing both at once restores proper debris deflection, which is worth the small premium for gravel-edged yards.
Frequently Asked Questions
What does LE720 actually refer to? LE720 is a platform name shared across multiple product lines. In outdoor power equipment, it points to walk-behind and stick edgers built by MTD, Troy-Bilt, and CRAFTSMAN. In personal watercraft, it identifies a specific Sea-Doo engine family from the early 2000s.
Are MTD and Troy-Bilt edger blades interchangeable? Not directly. The two brands share corporate ownership, but the LE720 blade geometry differs between housings, so ordering by brand badge keeps you on the safe side.
How do I match the starter relay to my watercraft? Check the OEM number stamped on the original relay. Cross-reference numbers like 278001376, 278002347, and 278001766 each match specific model years, and using the wrong number can leave you with the same no-crank symptom you started with.
Do I need to replace the blade guard at the same time? Only if the guard is bent or cracked. A guard that still deflects debris properly can stay in service while you swap the blade, but a dented guard throws rocks in unpredictable directions and is worth replacing alongside the blade.
Can I sharpen hardened steel edger blades instead of replacing them? You can, but the heat treatment makes the edge brittle and prone to chipping if you grind too aggressively. For most homeowners, swapping in a fresh blade is faster and safer than trying to re-edge a hardened cutter.
Wrap Up
The right LE720 part depends entirely on which machine you are repairing and what failed first. Start with the brand badge and model year on the housing, confirm the OEM number where applicable, and match the listing to that combination. The picks above cover the most common replacement needs across the platform, from edger blades to starter relays, so the right part should be a short scroll away.
