ThagBrco Cordless String Trimmer — Milwaukee 18V Compatible, 3‑in‑1 Trimmer/Edger/Mower (Tool‑Only)

ThagBrco Cordless String Trimmer is a versatile 3-in-1 battery-powered yard tool (trimmer, edger and small mower) that accepts Milwaukee 18V batteries—battery and charger sold separately.

If you already own compatible Milwaukee 18V batteries, this ThagBrco tool gives you a compact, cordless solution for trimming grass, edging borders and tackling light mowing tasks without adding another battery system to your garage. The unit is sold as a tool-only kit, so you can pop in existing Milwaukee 48-11-18xx batteries and get to work right away. It combines a rotating head, adjustable shaft and pre-wound line spools for quick setup and flexible operation around plants, patios and furniture.

How does this tool switch between trimming, edging and mowing?

The ThagBrco design uses a pivoting cutting head and adjustable shaft to convert quickly between modes. Rotate the head and change the shaft angle to move from straight-ahead trimming to vertical edging or a low-profile small mower position.

• 90° pivoting cutting head for multiple angles
• Adjustable shaft rotation up to 90° for sloped terrain
• 0–180° front handle adjustment for ergonomic control
• Quick, tool-free switching between modes

What batteries work with this ThagBrco string trimmer?

This tool is compatible with many Milwaukee-style 18V packs, giving flexibility to use batteries you already own. It accepts the common 48-11-1811, 48-11-1815, 48-11-1820 and similar series—note that no battery or charger is included with the tool.

• Compatible with Milwaukee 18V battery series (examples: 48-11-1811, 48-11-1850)
• Tool-only package; batteries and charger are not supplied
• Use higher-capacity packs for longer run time
• Simple slide-in battery mount for fast swaps

How easy is it to maintain and replace the cutting line?

Maintenance is straightforward because the ThagBrco uses pre-wound ABS spools and polyamide nylon line that snap in and out without tools. Replacement spools are ready to install, and the durable nylon line resists breakage for longer spool life.

• Four pre-wound replacement spools included or supported
• Durable polyamide nylon trimmer line for consistent cutting
• Tool-free spool snap-in design for fast changes
• ABS spool housing for secure, lightweight performance

What adjustments help when working around obstacles and slopes?

The adjustable head and handle let you position the cutting surface to reach under furniture, along fence lines and on uneven ground. You can tilt the shaft and rotate the head to maintain cutting efficiency without awkward bending or repositioning yourself.

• 90° head pivot to reach tight or low areas
• Shaft rotation that adapts to sloped yards and steps
• Front handle pivot from 0° to 180° for comfort and reach
• Compact form factor for maneuvering around plants and patios

Who this is for: The ThagBrco Cordless String Trimmer is ideal for homeowners and landscapers who already own Milwaukee-style 18V batteries and want a single lightweight tool for trimming, edging and light mowing. It fits small to medium yards where maneuverability, quick line changes and adaptable head angles matter most. If you need a battery-inclusive kit or heavy-duty commercial mowing power, consider pairing this tool with higher-capacity batteries or choosing a dedicated mower instead.
