The 10 Best String Trimmers With Bump Feed of 2026

What It Is and Who It's For

The BLACK+DECKER ST4500 is a corded electric string trimmer and edger that combines two tools into one lightweight package. Ideal for homeowners with small to medium yards, it's perfect for beginners who want reliable performance without the hassle of gas engines. Use it for post-mowing cleanup, edging driveways, and trimming around flower beds or trees.

Key Features and Real-World Performance

Powered by a 3.5 amp motor spinning at 10,000 RPM, it cuts a 12-inch path through grass and light weeds swiftly. The bump-feed spool lets you advance line without stopping, and the 180-degree rotating head flips seamlessly for edging. In everyday gardening, it excels at neatening lawn edges and reaching under shrubs, saving time on detailed yard work.

Build Quality and Durability

At just 4 pounds with an assist handle, it feels balanced and reduces fatigue. The cord retention hook keeps things secure, and plastic components hold up well for seasonal use. It's not built for daily heavy-duty jobs but shines for regular maintenance in home gardens.

Limitations and Final Verdict

The cord restricts mobility, so pair it with a quality extension cord. For small yards, it's a winner. Recommendation: Grab this if you need an affordable, easy-to-use trimmer for tidy lawns and edges; store it ready for spring cleanup.

Quick Start Guide

• Plug into a grounded outlet with a heavy-duty extension cord rated for outdoors.
• Hold with both hands on the assist handle and trigger for smooth control.
• Bump the spool head on the ground to feed more line as needed.

Best For

• Small yards (under 1/4 acre): Perfect for quick trims and edges without running out of cord reach.
• Medium lawns: Great with a 50-100 ft extension cord for full coverage.

Not Ideal For
