What’s different? The 2 differences that matter most, from the published figures.
- POWER+ 21 in Self-Propelled Mower (LM2102SP) runs on Battery / Cordless Electric; Power+ 20 in Mower runs on Battery / Electric. Fuel type sets what you buy and store; it is not a measure of power.
- POWER+ 21 in Self-Propelled Mower (LM2102SP) has a 21 in (533 mm) deck; Power+ 20 in Mower has a 20 in (508 mm) deck, a 1 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
