Side-by-side comparison of features, pricing, ratings, and alternatives.
The Black+Decker LST136W is a versatile cordless string trimmer designed to handle tough weeds, grass, and overgrown lawn edges with ease. Powered by a high-capacity 36V Lithium-Ion battery, it delivers reliable gas-like performance without the hassle of pull cords, mixing fuel, or dealing with extension cords. Featuring an innovative PowerCommand dial, users can easily choose between maximum runtime to maximize battery efficiency or maximum power to slice through thick brush. Its automatic feed spool (AFS) ensures continuous work without bumping, while the easily convertible wheeled edge feature transforms the trimmer into an edger for crisp lawn boundaries.

Equipped with a robust guide bar and chain, this battery-powered saw offers tool-less chain tensioning for quick adjustments on the go.
