Why customers choose Cera Garden

Overview

Introducing the YWTESCH 0.065 inch Single Line Trimmer Spool, a purpose-built replacement for Greenworks single-line auto-feed trimmers. This spool is engineered for single-line systems and is not interchangeable with dual-line or blue single-line spools. Before ordering, locate your trimmer model near the motor or battery to confirm compatibility.

Why choose this spool

  • Compatible with Greenworks single-line auto-feed models such as 21302, 21332, 21342, ST24B215, 2100302, STBA24B210, STBL24B210, ST24B05, ST24B217, STBL24B410, STBL40B501, ST40B05, ST40L213.
  • Drop-In refill eliminates winding and lets you install a pre-wound spool in seconds, so you can get back to trimming quickly.

Material and performance

Constructed from upgraded nylon polyamide, the line stands up to high-speed friction and heat. With a tensile strength exceeding 100 pounds, it maintains cutting power through dense weeds and small branches. The 0.065 inch diameter provides a balanced, lightweight profile that supports quieter operation and reduced vibration during longer sessions.

  • Premium materials deliver consistent performance at high speeds.
  • Lightweight diameter helps smoother rotation and less operator fatigue.

What’s in the kit and how it helps

The kit includes six spools plus two caps, offering multiple refills for large lawns. Each spool packs 16 feet of line and is designed for drop-in installation—thread the line through the eyelet and you’re ready to trim, with minimal downtime.

Real-world use cases

Perfect for maintaining expansive lawns, edging around flower beds, and trimming along fences or walls where clean, defined lines matter. The spools aim to deliver consistent cuts with fewer mid-cut stops, supporting a neat, well-defined yard appearance.

Care and notes

Always verify that your trimmer uses a single-line system before purchasing. Store spools in a dry place and avoid extreme heat to preserve line integrity. These spools are designed to offer a practical improvement for Greenworks trimmers, without promising guaranteed results.
