40-Pack 21.25" Line x .155-Inch String Trimmer Line Compatible with S-ENIX, Earth-Quake, B-ILT, Toro 58620, Fits Universal Walk Behind Mower and Other Mowers that Fit the Line Size

What It Is

This is a 40-pack of 21.25-inch long, 0.155-inch diameter trimmer line designed for walk-behind mowers that use a fixed-length line system (not spool-fed trimmers). It’s meant for edging along fences, flower beds, or driveways where a standard blade can’t reach.

Fitment & Compatibility

• Line dimensions: 21.25" length x 0.155" diameter. Measure your mower’s line holder slots—they must accept 0.155" line (common for Toro 58620, S-ENIX, Earth-Quake, B-ILT models). If your mower uses 0.130" or 0.160", this won’t fit.
• Mower type: Universal for walk-behind mowers with a dedicated line attachment (often a head on the side or rear). Not for string trimmers/weed whackers.
• Deck size: No deck size restriction—fits any mower with compatible line slots.
• OEM vs aftermarket: Aftermarket replacement. Works as a direct substitute for Toro 58620 and similar OEM packs. No adapters needed.
• Check before buying: Confirm your mower uses pre-cut line (not a spool). Look up your model’s line diameter spec in the manual or measure the existing line with a caliper. If your mower has a bump-feed head, this is the wrong product.

Key Things to Know

• Installation: Tool-free—just push each line into the holder slot until it locks. No winding or cutting required.
• Durability: 0.155" line is thicker than standard 0.130", so it lasts longer against concrete and gravel but may be stiffer in cold weather.
• Common gotcha: The 40-pack lasts roughly 10–15 uses depending on terrain. Buy two packs if you mow large yards or hit a lot of hard surfaces.
• Quality: Aftermarket line can be slightly less flexible than OEM Toro line. It holds up fine for grass and light weeds but may snap faster on heavy brush.

Should You Buy It

If you own a walk-behind mower that uses pre-cut 0.155" line (like Toro 58620 or compatible brands) and want a cost-effective bulk option, this is a solid buy. Skip it if your mower uses a spool system or a different line diameter—check your manual first.
