The EGO AB2101D is a genuine two-blade replacement set for selected 21-inch EGO Select Cut mowers. It includes the heavy-duty mulching lower blade and the upper blade used by EGO’s Multi-Blade System. Mounting nuts and bolts are not included.
Our verdict: Buy the AB2101D when you own a compatible Select Cut mower and want to prioritize fine clipping recirculation. It is the straightforward OEM choice for replacing both blades together. It is not a universal blade for every 21-inch EGO mower, so confirm the exact mower model before ordering.
Research note: This is a research-based review. I have not personally tested this blade set. I checked EGO’s current product page, 2026 accessory chart, included parts, compatibility list, and installation guidance on September 5, 2026.

Will the AB2101D fit your mower?
EGO’s current product page lists the LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, and LM2156SP. These are Select Cut machines that use an upper blade together with an interchangeable lower blade.
Do not choose this set solely because your mower has a 21-inch deck or uses a 56V battery. EGO also sells 21-inch single-blade mowers and newer 22- and 30-inch models with different blade systems. Match the complete model number on the mower label, including the letters after the number.
What is included?
The AB2101D contains two steel blades:
- Mulching lower blade: the heavy-duty curved blade that EGO says turns clippings into fine fragments.
- Upper blade: the second blade in the Select Cut system, which cuts grass lifted by the lower blade.
Nuts, bolts, flanges, and other mounting hardware are not included. Reuse only the correct serviceable hardware specified in your mower manual. Replace damaged or missing hardware with the exact EGO parts called for by that manual.
AB2101D vs other Select Cut blade sets
| Blade set | Primary purpose | What changes |
|---|---|---|
| AB2101D | Mulching | Mulching lower blade plus upper blade |
| AB2100D | Extended runtime | Extended Run Time lower blade plus upper blade |
| AB2102D | High-lift bagging | High Lift Bagging lower blade plus upper blade |
The AB2101D is the better match when you regularly leave clippings on the lawn and want finer fragments. The AB2102D is designed for stronger lift into the collection bag. The AB2100D is intended to reduce cutting load and favor runtime. Lawn conditions still affect the result, so there is no single best lower blade for every job.
What the original page got wrong
The earlier review described the interchangeable lower blade as though the AB2101D could switch between mulching and bagging configurations by itself. The set does not contain all three lower-blade options. It contains the mulching lower blade and the common upper blade. To change the system’s emphasis, you install a different compatible lower blade or blade set.
The earlier copy also relied on broad claims about customer satisfaction and long-term durability without showing evidence. This update removes those claims and focuses on documented compatibility, included parts, and the choice among EGO’s three Select Cut blade types.
Installation considerations
Remove the battery pack and safety key before servicing the mower. Wear protective gloves, place the mower as directed in its manual, and note the order and orientation of the fan, flanges, blades, nuts, and bolt as they come off.
The two blades must be assembled in the orientation shown in EGO’s instructions, and each face marked for the deck or grass must point the correct way. Use a torque wrench and the torque values in the manual for your exact mower. A loose, reversed, or incorrectly stacked blade assembly can damage the mower and create a serious hazard.
Pros and cons
Pros
- Genuine EGO replacement set.
- Includes both the mulching lower blade and upper blade.
- Designed for the Select Cut Multi-Blade System.
- Clear current compatibility list from EGO.
- Lets compatible-mower owners restore the complete two-blade stack.
Cons
- Does not fit every 21-inch EGO mower.
- Mounting nuts and bolts are not included.
- Mulching focus may be less suitable than the high-lift set for frequent bagging.
- Correct two-blade orientation and torque matter during installation.
Frequently asked questions
Does AB2101D include two blades?
Yes. It includes the mulching lower blade and the upper blade for the Select Cut Multi-Blade System.
Are the mounting nuts and bolts included?
No. EGO explicitly states that nuts and bolts are not included.
Can it fit a standard single-blade EGO mower?
Do not assume so. EGO specifies this set for selected Select Cut models. Check the complete mower model number against the current compatibility list.
Can the AB2101D be used for bagging?
EGO describes the lower blade as a heavy-duty mulching and bagging blade, but the AB2102D High Lift Bagging set is the purpose-built option when maximum bagging lift is the priority.
Should both blades be replaced together?
The AB2101D is sold as a complete set. If one blade is damaged, inspect the full stack and mounting hardware and follow EGO’s service guidance. Keeping a matched, correctly balanced assembly matters.
Final recommendation
The AB2101D is the sensible OEM replacement for owners of a compatible EGO Select Cut mower who mainly mulch and need the complete upper-and-lower blade pair. Verify the mower model first. If you mostly bag leaves or heavy grass, compare the AB2102D high-lift set before buying; if runtime is the priority, compare the AB2100D.
