Hart .080" Line & Spool

What It Is

The Hart .080" Line & Spool is a pre-wound replacement trimmer head for Hart 40V and 60V battery-powered string trimmers. It’s designed for light to medium trimming of grass and small weeds, not heavy brush.

Fitment & Compatibility

• Check your model: Fits most Hart 40V and 60V trimmers (e.g., models HTPA40, HLST401, HLST601, and similar). Look for a “.080” line” or “spool replacement” reference in your manual or on the existing spool.
• Line diameter: Uses .080-inch (2mm) line. Do not use thicker line—it won’t fit the spool or may damage the trimmer head.
• Spool type: Pre-wound, bump-feed spool. It’s a direct replacement for the original Hart spool. Not compatible with other brands (e.g., Ryobi, Milwaukee) without an adapter—verify spool size and hub shape.
• OEM vs aftermarket: This is an OEM Hart part. Aftermarket spools may fit but often have looser tolerances or inconsistent line quality. Stick with OEM for guaranteed fit.

Key Things to Know

• Quality: .080” line is durable for residential use but snaps easier than .095” or .105” line. Avoid hitting rocks or concrete edges.
• Installation difficulty: Easy—pop off the trimmer head cover, remove the old spool, insert the new one, thread the line through the eyelets, and snap the cover back on. No tools needed.
• Common gotchas: The line can weld itself to the spool if the trimmer overheats (e.g., from continuous high-speed use). Let the trimmer cool between heavy jobs. Also, the bump-feed mechanism may stick if the line is over-wound or if debris gets inside the head.
• Line length: Each spool holds about 20 feet of line. You’ll get 1-2 full trims on a typical lawn before needing a replacement.

Should You Buy It

Buy this if you own a Hart 40V or 60V trimmer and want a hassle-free, drop-in replacement spool with consistent .080” line quality. It’s ideal for homeowners who need reliable, light-duty trimming without the mess of winding your own line. Skip it if you have a different brand trimmer or need heavy-duty .095”+ line for thick brush.
