EGO’s Select Cut system is the defining feature of their 21-inch mowers, letting you swap blades for different jobs. This AB2101D set is the dedicated mulching pair. It’s a two-blade system designed to work in concert, pulverizing grass clippings into a fine, nutrient-rich dust that disappears back into your lawn.

The lower blade is the workhorse. It’s a heavy-gauge steel blade that cuts and lifts the grass. The upper blade then slices those clippings again before they can escape the deck. The result is a noticeably finer mulch that decomposes quickly, eliminating the need to bag. You get a clean cut and a lawn that feeds itself. The set is a direct swap for the high-lift or extended runtime blades, a change that takes about ten minutes with a wrench.

These are replacement blades, so their value is in restoring your mower’s original mulching performance. They are specifically for EGO Select Cut 21-inch models like the LM2133 and LM2130. Keep your original blade bolts, as they aren’t included. When your cut gets ragged or you see whole clippings left behind, this set gets the system working like new.
