Runtime per charge
1/3-acre yard run-time (single battery, max mode): EGO LM2156SP (56V, 10Ah) 75 min, Greenworks Pro 80V (4Ah) 50 min, Kobalt 80V (5Ah) 55 min, Ryobi 40V HP (8Ah) 60 min, DeWalt 2x20V MAX (2x8Ah) 45 min.
Two-battery setups let you finish a 1/2-acre yard: EGO sells dual-battery models, DeWalt is 2x20V MAX by default, Greenworks/Kobalt 80V single-battery is enough for most yards.
Recharge time: EGO 60 min, Greenworks 80V 30 min, Kobalt 80V 45 min, Ryobi 40V 90 min, DeWalt 20V 60 min per battery (so 120 min for both). Greenworks 80V recharges fastest.
Cut quality and bagging
Cut quality on wet morning grass: EGO best (high RPM brushless motor + steel deck), Greenworks Pro very close, Kobalt close, Ryobi adequate, DeWalt slightly behind due to lower torque on 2x20V setup. All 5 do a fine job on dry grass.
Bagging vs mulching: All 5 support both. EGO and Greenworks Pro bagging is the cleanest (less spillage at the chute). Ryobi 40V HP includes a side-discharge chute for very tall grass.
Self-propulsion: EGO LM2156SP and Kobalt 80V offer self-propelled variants. The standard models are push-only. Self-propelled is worth the upgrade if your yard has any slope.
Battery platform lock-in
You're not just buying a mower — you're committing to a battery platform. EGO has the broadest lineup (mower, trimmer, blower, snowblower, chainsaw). Ryobi 40V is similarly broad. Greenworks 80V and Kobalt 80V are mower-focused with fewer accessory options. DeWalt 20V MAX is dominated by power tools — fewer outdoor accessories.
Best decision framework: if you already own DeWalt tools, the 2x20V mower is a no-brainer. If you don't have battery tools yet, EGO or Ryobi 40V give you the broadest outdoor + tool ecosystem.
