MZK 40V Cordless 13in Lawn Mower - Lightweight Brushless

In this review of the MZK 40V (2 x 20V) 13Cordless Electric Lawn Mower the bottom line is simple: this mower is for homeowners who want a lightweight, low-maintenance cordless option for small to medium yards. The single biggest reason to buy is the combination of a modern brushless motor with two included 4Ah batteries, which delivers clean cutting power and longer runtime without the fuss of cords or heavy gas engines. It feels purposely designed for easy handling and quick jobs rather than commercial workloads.

Key Features

• Brushless Motor: The advanced brushless motor provides efficient power with lower maintenance and smoother operation than brushed alternatives.
• Dual 4Ah Batteries: Two 4Ah 20V batteries (40V system) extend runtime and reduce interruptions for finishing typical residential lawns.
• 13in Cutting Width: The 13in cutting path balances maneuverability and coverage to reduce the number of passes on small yards.
• 4-Position Height Adjustment: Four cutting heights from 1.5in to 2.8in let you adapt to different grass types and seasonal needs.
• Lightweight Build: At about 26.5 lb the mower is easy to push, lift into a trunk, and store in compact spaces.
• Safety Two-Step Start: The two-step activation adds safe startup control so the mower only runs when intentionally engaged.

Who It's For

The MZK mower is best for homeowners with small to medium-sized lawns who want a cordless, low-maintenance machine that is easy to handle. If you need a mower that is simple to transport, store, and start, this is a practical choice, especially for users who prefer lighter equipment and reliable brushless performance.

It is less suitable for very large properties, commercial use, or those who require wide cutting decks and bagging capacity for high-volume grass. Buyers who need mulching features or heavy-duty power should consider larger walk-behind models instead.

Pros & Cons
