MILWAUKEE M18 FUEL String Trimmer 2825-20ST Bare tool (Battery and Charger sold Separately) (Renewed)

What It Is

This is a bare tool version of the Milwaukee M18 FUEL String Trimmer (model 2825-20ST), a cordless trimmer head and motor assembly with no battery or charger included. It’s designed for medium-to-heavy trimming tasks around lawns, gardens, and landscaping, and is compatible with Milwaukee’s M18 battery system.

Fitment & Compatibility

Before buying, verify you already own an M18 battery (e.g., 5.0Ah, 8.0Ah, 12.0Ah) and a compatible M18 charger—this is a bare tool only. The trimmer accepts standard .080-inch or .095-inch trimmer line (sold separately) and uses a universal bump-feed head. It fits most Milwaukee M18 battery platforms, but check the battery release tab alignment—older M18 batteries may have slightly different latching, though all M18 batteries physically connect. No deck size or specific mower brand compatibility is needed—it’s a standalone trimmer.

Key Things to Know

• Renewed condition: This is a factory-refurbished unit. Expect minor cosmetic wear (scuffs, scratches) but full functionality. Warranty may be shorter than new (often 90 days vs 5 years).
• Installation difficulty: Zero—no assembly required. Just attach a battery, load trimmer line, and start. Line loading is straightforward but read the manual for the correct wrap direction.
• Power vs battery life: The trimmer is powerful (equivalent to a 35cc gas unit), but battery drain is fast. A 5.0Ah battery gives ~25-30 minutes of continuous use; a 12.0Ah gives ~60 minutes. Have spare batteries for larger yards.
• Common gotcha: The bump-feed head can jam if line is too thick or overlapped. Use .095-inch line for heavy weeds, .080-inch for light trimming. Avoid overloading the spool.

Should You Buy It

Buy this if you’re already invested in Milwaukee M18 tools (have batteries and charger) and want a reliable, powerful cordless trimmer at a discount. Skip it if you need a complete kit with batteries/charger, or if you prefer a new unit with full warranty—the renewed savings (~$50-80 off new) come with cosmetic imperfections and limited protection. Best for DIYers or pros with existing M18 gear who value power over pristine looks.
