RB 40V Brushless Cordless Lawn Mower 13" — 4.0Ah Battery, Fast Charger, 2‑in‑1 Mulch/Bag

RB's 40V 13-inch brushless cordless mower is a lightweight, low-noise electric mower that runs on a 4.0Ah battery and offers bagging or mulching in a compact, easy-to-store design.

This compact mower pairs a brushless motor with a 4.0Ah lithium-ion battery to deliver up to 30 minutes of runtime, instant push-button start, and minimal upkeep compared with gas models. Its 13-inch cutting deck, 2-in-1 bagging/mulching options, and foldable handles make it a practical choice for small to medium yards and for homeowners who want a quieter, eco-friendlier alternative.

How long will one charge actually last for typical yard work?

On a full charge the RB 4.0Ah battery supports roughly 30 minutes of continuous mowing under normal conditions. Real-world runtime varies by grass height, cutting speed, and whether you use bagging or mulching, but the quick-charge system and removable battery make it easy to swap in a second pack if needed.

• Rated runtime: up to 30 minutes on a single 4.0Ah battery.
• Fast charger included to reduce downtime between jobs.
• Removable battery for quick swaps and convenient storage.

What advantages does the brushless motor provide over brushed designs?

The brushless motor increases torque and efficiency while reducing noise and maintenance needs. Without carbon brushes, the motor runs cooler and lasts longer, giving you more consistent cutting power and fewer service requirements than a traditional brushed motor.

• Higher torque for cleaner, more consistent cuts.
• Lower operational noise—good for early mornings and quiet neighborhoods.
• Reduced maintenance with no brushes to replace.

Can this mower handle both bagging and mulching, and how do I switch modes?

Yes — the RB 13" mower supports a simple 2-in-1 configuration: attach the rear bag for clippings removal or install the mulching plug to return finely chopped clippings to the lawn. Transitioning between modes is straightforward and tools-free, so you can adapt to seasonal cleanup or routine mowing quickly.

• Bag mode: collects clippings for a neat finish and easy disposal.
• Mulch mode: chops clippings finely to help return nutrients to soil surface.
• Tool-free swapping for fast changeovers between tasks.

How portable and easy to store is this mower for small properties?

At just 28 lbs and with a foldable handle, this mower is highly portable and simple to lift into storage or a garage shelf. The compact 13" deck and 6-inch wheels make it nimble across driveways, patios, and tight lawn edges, and the lightweight design reduces strain during transport.

• Lightweight 28 lb chassis for easy handling and lifting.
• Foldable handle reduces storage footprint in sheds or closets.
• 6" wheels designed for smooth movement across small yards.

Who is this for: The RB 40V 13" Brushless Cordless Lawn Mower is suited for homeowners with small to medium-sized lawns, renters or condo owners who need a quiet, low-maintenance mower, and anyone who prefers an eco-friendly, easy-to-store tool. It’s ideal if you value quick starts, minimal upkeep, and the flexibility of bagging or mulching without dealing with gas, oil, or complex engine servicing.
