WEED WARRIOR Autowinder II Universal Fit String Trimmer Bump Head — Quick-Reload, Heavy-Duty Feed (0.080–0.105")

The WEED WARRIOR Autowinder II replacement bump head lets you reload trimmer line quickly by inserting the line and cranking the knob—no spool disassembly required.

If you maintain a gas-powered string trimmer and dread tangled spools or fiddly line changes, this Autowinder II head is made to simplify the job. Designed for heavy-duty yard work, it accepts common cutting line diameters and installs in place of many original bump-feed heads. The result is a faster reload process, fewer interruptions while trimming, and a professional-grade feel for homeowner and pro users alike.

How does the Autowinder II speed up line changes?

Instead of opening the head and winding line onto a spool, you simply feed the line into the head and rotate the external bump knob to wind the line internally. That reduces downtime and removes the need for fiddly spool alignment. Because line is wound by the mechanism, there's less chance of cross-winding or jamming.

• Insert cut line and crank the bump knob to load—no disassembly.
• Continuous winding reduces tangles compared with spool swaps.
• Works with lengths up to roughly 16 feet of line per load.

Which trimmers and line sizes will this head fit?

The Autowinder II is built as a universal-fit replacement for many popular gas trimmer models and is compatible with numerous factory brands. It accommodates common trimmer line diameters so you can use the cord you prefer. Check your trimmer’s shaft and attachment thread to confirm fit before purchase.

• Accepts trimmer line from 0.080" to 0.105" diameter.
• Designed primarily for gas-powered trimmers; many universal mounts fit Echo, Stihl, Husqvarna and others.
• May fit some cordless models with matching mounting dimensions—verify before installing.

Is the Autowinder II durable enough for professional use?

WEED WARRIOR builds this bump head to withstand repeated field use and demanding trimming tasks. Materials and construction emphasize impact resistance and reliable feed action so landscapers and serious homeowners can expect consistent performance. Routine maintenance—keeping the mechanism clean and using recommended line—extends service life.

• Professional-grade construction for repeated bump-feed cycles.
• Designed after lab and field testing to resist jamming and wear.
• Compatible with WEED WARRIOR line and common aftermarket cords for optimal durability.

How easy is installation and everyday operation?

Installation is straightforward: remove your existing bump head and mount the Autowinder II in its place using the same fitting system. Daily operation is as simple as feeding line and rotating the knob; the bump action operates like a traditional bump-feed head but without opening the housing. Basic cleaning and occasional lubrication keep the action smooth.

• Swap in place of most factory bump heads using the same mounting interface.
• Load line by inserting and cranking—no spool removal required.
• Simple cleaning and inspection prevents debris buildup and keeps feed reliable.

Who is this for? The WEED WARRIOR Autowinder II is aimed at homeowners who want faster, less frustrating line changes and at landscape professionals who need a rugged, quick-service replacement head. It suits anyone using a gas-powered string trimmer who wants to reduce downtime, avoid tangled spools, and use standard 0.080"–0.105" cutting line. If you value quick maintenance and broad compatibility with common trimmer brands, this bump head is a practical upgrade.
