EGO Select Cut High-Lift vs. Mulching Blades: which lower blade should you use?

AB2102D is EGO's high-lift option for bagging; AB2101D is the mulching lower blade. Both are replacement blade sets for specific 21-inch Select Cut models. Match the exact mower model and follow its manual for the swap.

Blade choice

High-lift for bagging; mulching for returning clippings

Lower blade set	Intended job	What to know
AB2102D High-Lift	Bagging clippings with the mower's collection setup.	A high-lift lower blade configuration. EGO supplies this as a dual-blade set; retain the matching upper blade and install the stack as directed in your mower manual.
AB2101D Mulching	Mulching clippings with the mulch plug/setup.	EGO's mulching lower blade set. Use the configuration and accessories specified for your exact mower.

Blade selection alone does not establish a specific cut quality, leaf pickup result, or battery runtime. Grass condition, cut height, travel speed, self-propel use, and other factors affect the job. We found no EGO specification supporting a universal 10%–15% runtime difference, so this guide does not assign one.

EGO lists these sets for approved 21-inch Select Cut models: LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, and LM2156SP. Check the label on your mower and the deck manual. Do not extend that list to a similarly named mower or variant without confirmation from EGO.

Service guidance

Use the exact mower manual for blade removal and torque

Blade work can cause severe injury. Remove the battery and safety key, wear protective gloves, and follow the procedure and safety warnings in the manual for your mower. If you are unsure about the blade stack, fasteners, or tools, have an authorized service location do the work.

Remove the battery and safety key before tipping or servicing the mower. Follow the manual's directions for its orientation and service position.
Photograph or note the installed blade stack before removal. Keep the upper blade on top and lower blade beneath it as labeled; the lower blade's “THIS SIDE FACING DECK” marking faces the deck.
Use the manual-specified blade locking method and tools. Do not substitute an improvised lock or rely on a generic socket-size instruction.
Reassemble the complete blade stack in the documented order. Do not operate the mower with a blade omitted or the stack assembled contrary to its manual.
Torque each fastener to its own manual value. In the cited EGO Select Cut instructions, the shaft bolt is 22 ft-lb (30 Nm); blade-set nuts are 36–43 ft-lb (50–60 Nm). These are different fasteners. Never apply the set-nut value to the shaft bolt.

Confirm the manual revision and fastener diagram for your exact mower. The AB2102D blade manual helps identify the blade orientation, while mower-specific service instructions govern the mower hardware.
