BLACK+DECKER 20V MAX String Trimmer/Edger with Removable Mower Deck

In this review of the BLACK+DECKER 20V MAX String Trimmer/Edger with removable mower deck, the bottom line is simple: this is a versatile battery-powered tool for homeowners who want an easy-to-use alternative to gas models. It converts between a 12' trimmer, a wheeled edger and a small mower deck, so the single biggest reason to buy is its flexibility for light to medium yard maintenance without the noise and fuss of gas. The unit is also noticeably lighter and easier to start than gas trimmers, making it a practical choice for quick trimming and edging tasks.

Key Features

• Three tools in one: Converts quickly from a 12' string trimmer to a wheeled edger or a small mower deck, so you can tackle multiple tasks with one machine.
• Power Drive Transmission: Provides increased torque compared with basic cordless heads, which helps maintain cutting performance on thicker grass and through light overgrowth.
• Removable mower deck: The included deck converts the trimmer into a compact mower for small patches, offering a more finished cut where a full mower is impractical.
• Two height adjustments: The mower deck has adjustable heights so you can set an ideal cutting level for different grass conditions and preferred lawn appearance.
• Battery configuration: Uses two 1.5 Ah batteries to balance run time and weight so the tool remains lighter than many gas alternatives while still delivering usable runtime for small yards.

Who It's For

This tool is best for homeowners with small to medium yards who value convenience and ease of use over extended run time. It suits users who need quick trimming, edging and occasional small-area mowing without hauling a gas unit or dealing with mixing fuel.

It is less suited for large properties or heavy-duty commercial work where longer battery life and more sustained power are required; landscapers or owners of very large lawns should look for full-size cordless or gas-powered mowers and trimmers designed for prolonged use.

Pros & Cons

Pros

• Converts between trimmer, edger and small mower, reducing the need for multiple tools.
• Power Drive Transmission gives better torque for tougher cutting than entry-level electric heads.
• Lightweight and easy to start, making it more user friendly than comparable gas models.
• Good perceived value and build quality for homeowners at this price point.

Cons

• Battery life and long-term durability receive mixed feedback, so heavy users may find run time or longevity limiting.
