BLACK+DECKER 40V MAX 13-inch Cordless String Trimmer & Edger LST136 — 2.0Ah Battery, Telescoping Shaft

The BLACK+DECKER 40V MAX 13-inch cordless string trimmer and edger (LST136) is a battery-powered 2-in-1 grass trimmer that converts quickly to an edger and includes a 40V 2.0Ah battery plus fast charger.

This compact electric trimmer blends a high-output 40V MAX lithium-ion battery with a POWERDRIVE transmission to deliver stronger cutting torque and consistent performance without a gas engine. Designed for homeowners who want a lightweight, quieter alternative to gas tools, the unit features an automatic line-feed system that eliminates bumping and a PowerCommand dial that balances power versus runtime for different jobs.

How does the LST136 handle thick or overgrown weeds?

The POWERDRIVE transmission routes more motor power to the cutting string so the trimmer cuts dense vegetation more effectively than basic consumer models. The high-speed spool spins up to 8,500 RPM for cleaner cuts through tougher stalks.

• PowerDrive boosts torque to the cutting head for harder cuts.
• 40V MAX battery supplies higher voltage output than typical 20V tools.
• High-speed operation (up to 8,500 RPM) for efficient cutting.

What makes battery management and runtime easy?

Built-in charge-state indicators show remaining battery capacity so you can plan work sessions. The included 2.0Ah battery and fast charger get you back to the yard quickly; a PowerCommand dial lets you choose between maximum power or extended runtime depending on the task.

• Battery level indicator on the pack for quick status checks.
• Fast charger replenishes the battery in about two hours or less.
• PowerCommand dial toggles between power and runtime modes.

How simple is the switch from trimmer to edger and operation comfort?

The LST136 converts to an edger in seconds without tools, so you can follow up trimming with precise edging along sidewalks and driveways. Adjustable telescoping shaft and soft-grip handle let you set a comfortable reach and reduce fatigue during longer sessions.

• Tool-free conversion transforms the head from trimmer to edger quickly.
• Telescoping pole adjusts to different user heights for ergonomic use.
• Auxiliary handle and soft-grip main handle improve control and comfort.

What user-friendly features improve everyday yard work?

An Automatic Feed Spool (AFS) eliminates the need to bump the head to advance line, keeping trimming continuous and less fussy. The kit arrives with essential accessories—extra spool, guard, and an auxiliary handle—so you can begin work straight away.

• AFS automatically supplies cutting line as needed without bumping.
• Complete kit includes battery, fast charger, extra spool, guard, and handle.
• 3-year limited warranty provides added peace of mind for homeowners.

Who is this for? Homeowners with small to medium lawns who want a low-maintenance, quieter alternative to gas trimmers will appreciate the LST136. It suits people who value easy startup, quick conversion to edging, and the portability of a cordless system—especially those trimming yards, sidewalks, and flower bed edges without dealing with cords or fuel mixing.
