LIYYOO 20ft 0.080 Inch SF-080 String Trimmer Replacement Auto Feed Spool Line Compatible with GH3000 LST540 LST540B GH3000R SF-080-BKP String Trimmer(6 Pack)

What It Is

The LIYYOO SF-080 is a 6-pack of pre-wound 0.080-inch trimmer line spools designed for automatic feed string trimmers. It’s a direct replacement for worn-out spools on compatible models, saving you the hassle of hand-winding line.

Fitment & Compatibility

Check three things before buying:

• Line diameter: 0.080 inch (2.0 mm) – fits trimmers that spec 0.080 or 0.065 line. Do not use on trimmers requiring 0.095+ line (risks jamming or poor cutting).
• Spool dimensions: Fits GH3000, LST540, LST540B, GH3000R, and SF-080-BKP models. Not universal – verify your trimmer’s model number on the OEM spool or manual.
• Feed mechanism: Works with bump-feed and auto-feed heads that accept a standard square or round spool. If your trimmer uses a specific brand-locked spool (e.g., some Husqvarna or Echo), confirm the center hole and slot alignment matches.

OEM vs aftermarket: This is an aftermarket replacement. It’s not made by the original trimmer manufacturer, but dimensions are cloned from OEM SF-080 spools. No modifications needed if your model is listed.

Key Things to Know

• Line quality: 0.080 line is thin – good for light weeds and grass, but will snap quickly on thick brush or against fences. Not for heavy-duty clearing.
• Installation: Pre-wound spools drop in – no winding. You may need to trim the line to the correct length (typically 6-8 inches per side) for proper auto-feed. Over-long line causes head imbalance.
• Gotcha: Auto-feed can be inconsistent if the spool is slightly warped or if the trimmer head is dirty. Clean the head before installing. Some users report the line tangles if the spool isn’t seated perfectly flat.
• Value: 6 spools for ~$7.88 is cheap. Expect shorter lifespan per spool than thicker line (0.095+), but cost per spool is low.

Should You Buy It

Buy this if you have a compatible trimmer (GH3000, LST540, etc.) and only need to cut light grass and weeds around the yard. Skip it if you tackle thick weeds, saplings, or blackberry vines – you need 0.095+ line. For the price, it’s a good stock-up for routine trimming, but don’t expect heavy-duty durability.
