PowerSmart MB2400B 40V 21" Brushless Cordless Push Lawn Mower | Two Batteries & Charger Included

More Deck. More Runtime. Two Batteries Included.

The PowerSmart MB2400B steps up from the 17" lineup with a wider 21" brushless steel deck and two 40V batteries in the box — so when the first battery runs low, you swap and keep mowing without waiting for a recharge. Push-button start, zero emissions, and a foldable handle that saves up to 70% of storage space make this the upgrade pick for mid-to-large residential lawns.

Key Features

• 21" Brushless Steel Deck — Wider cutting path covers more ground per pass vs. 17" models; brushless motor delivers more torque, longer runtime, and longer tool lifespan than brushed alternatives
• Two 40V Batteries Included — Swap batteries mid-mow for extended uninterrupted runtime; both batteries compatible with all PowerSmart 40V outdoor tools
• 2-in-1 Cutting: Mulch or Bag — Mulch clippings back into the lawn for natural fertilization, or collect in the rear bag for a clean finish
• 6-Position Cutting Height Adjustment — 1.5" to 3.9" range; single-lever adjustment changes all four wheels at once for quick seasonal changes
• Push-Button Start — No pull cord, no gas, no oil, no fumes; starts instantly every time with zero maintenance
• Foldable Handle — Saves Up to 70% Storage Space — Folds flat for compact storage in a garage, shed, or car trunk; significantly smaller footprint than a gas mower

MB2400B vs. MB2417A — Which Is Right for You?

• MB2417A (17") — Best for small yards; one battery included; 3-in-1 (mulch/bag/side discharge)
• MB2400B (21") — Best for mid-to-large yards; two batteries included; wider deck for faster mowing

Perfect For

• Mid-to-large residential lawns
