Oregon 2-Line Speed-Feed 4.5" Trimmer Head — Universal Semi-Auto, Loads in 30s

Oregon’s 2-Line Speed-Feed 4-1/2" Trimmer Head is a universal, semi-automatic replacement that loads in 30 seconds and fits most straight-shaft gas and electric trimmers.

Built for landscapers, contractors, and homeowners who need a fast, reliable trimming solution, this Speed-Feed head focuses on simple reloading, robust construction, and broad compatibility. It uses a two-line bump-feed design to deliver steady cutting through heavy grass and tough weeds, and it includes three adapter sizes so you can mount it on the majority of straight-shaft brands without extra parts.

How fast and simple is the reloading process?

Reloading is designed to take less than half a minute with no disassembly. Feed equal lengths of line through the head, grip the ergonomic collar, and wind until the lines are secure — then you’re ready to trim.

• Loads in 30 seconds or less with no tools
• Ergonomic easy-grip collar for quick winding
• No need to remove the head or take apart the spool

What fits my trimmer — which shafts and adapters are included?

This head is made for straight-shaft trimmers and ships with three common adapter sizes so it installs on many popular models. It supports both right- and left-hand thread standards to broaden compatibility across brands.

• Includes 7mm x 1.0 RH, 8mm x 1.25 LH, and 10mm x 1.25 LH adapters
• Compatible with Stihl, Shindaiwa, Stens, Rotary, RedMax, Troy-Bilt and others
• Direct-mount design for most straight-shaft trimmer spindles

How does it perform on heavy vegetation and rough conditions?

The Speed-Feed uses two cutting lines and a durable housing to maintain a steady cut in medium to heavy-duty scenarios. It’s engineered to resist wear from abrasive debris and hold line securely under frequent use.

• Semi-automatic bump-feed keeps line length consistent during operation
• Rugged construction resists impacts and rough terrain
• Handles tall grass, thick weeds, and edging tasks reliably

What line capacity and sizes can I use?

The spool accepts a generous length of trimmer line so you can run longer between reloads, and it accommodates a range of thicknesses and shapes. Use the line size recommended for your cutting needs and machine specifications.

• Holds up to 15 feet (4.6 meters) of .095" (2.4 mm) line
• Accepts up to .105" (2.7 mm) maximum line diameter of any shape
• Suitable for standard round or specialty cutting lines within size limits
