WORKPRO WORKPROX 12in 20V Cordless Weed Wacker - 4.0Ah Battery, 2-in-1 Trimmer & Edger with Auto Line Feed

The WORKPROX 12-inch 20V cordless weed wacker is a 2-in-1 battery-powered string trimmer and edger engineered for fast, comfortable yard cleanup with an upgraded 4.0Ah battery and automatic line feed.

Lightweight but powerful, the WORKPROX 20V grass trimmer combines a high-speed motor with a long-lasting battery and user-friendly controls so you can tackle overgrown borders, lawn edges, and medium-size yards without a cord. It ships with two replacement spool lines and a host of convenience features—an edging wheel, adjustable head, telescoping shaft, and USB-C battery charging—that make routine trimming faster and less tiring.

How does this trimmer switch between trimming and edging?

The WORKPROX model converts instantly from a string trimmer to a precision edger using a single button and an edging wheel for guided cuts. That quick-change design removes the need for additional tools or attachments and helps maintain clean lines along sidewalks and flowerbeds.

• One-button mode change for trimmer or edger operation
• Integrated edging wheel to stabilize edges and guide the cut
• Spacer guard to protect plants and landscaping while you work

What should I expect from runtime and battery charging?

Equipped with a WORKPROX 4.0Ah upgraded battery, the trimmer delivers up to roughly 50 minutes of runtime on a full charge, depending on cutting conditions. The battery pack includes an electronic level display so you can monitor remaining power, and its USB-C charging lets you use modern chargers, power banks, or car adapters for flexible recharging (charger not included).

• 4.0Ah WORKPROX battery with on-pack power indicator
• USB-C charging compatible with common power sources
• Quick swap battery design lets you carry a spare for extended jobs

How effective is the cutting system and what maintenance features help?

The trimmer runs up to 9,500 RPM and uses a 0.055-inch spool line with a cutting swath up to 12 inches for efficient clearing of grass and light weeds. An automatic line-feed mechanism senses when line is short and advances it for continuous cutting, while an onboard blade trims excess line after feed so you don’t stop to manually reload as often.

• High-speed 9,500 RPM motor for quick cutting
• Durable 0.055-inch line rated to resist breaking under normal load
• Auto line feed that trims excess line for hassle-free restarts

Can I adjust the tool for comfort and reach?

The WORKPROX trimmer is built for ergonomic use: a 90° adjustable cutting head plus a 150° auxiliary handle let you find a comfortable angle, and the telescoping shaft extends up to 22 inches to reduce bending. These adjustments help lower fatigue during longer trimming sessions and improve control for precise edging.

• Telescoping shaft extends up to 22 inches for varying user heights
• 90° rotatable cutting head for tight spaces and vertical edging
• 150° auxiliary handle to customize grip and leverage

Who this is for: Homeowners and renters with small-to-medium lawns, gardeners who want a cordless, tool-free transition between trimming and edging, and anyone who values a lightweight trimmer with a long-lasting 4.0Ah battery and automatic line feed. It’s ideal for property upkeep, trimming along fences and beds, and quick cleanup jobs where portability and ease of use matter most.
