What It Is

This is a 2-pack of aftermarket trimmer heads designed to replace the Echo Speed-Feed 400 on straight-shaft trimmers. It’s a direct fit for Echo SRM-225, SRM-230, SRM-210, SRM-2100, PAS-210/211/225/230/260, and Shindaiwa T195S/T220/T222/T230/T231 models.

Fitment & Compatibility

Before buying, confirm your trimmer has a straight shaft (not curved) and uses the Echo Speed-Feed 400 style head. Measure the shaft diameter – it must be compatible with the included adapter bushings (typically 25mm or 26mm). These heads do not fit curved-shaft trimmers or models with a different mounting system (e.g., bump-feed heads). Check your trimmer’s model number label on the shaft or engine housing. This is an aftermarket part, not OEM Echo, so minor fit differences are possible.

Key Things to Know

• Quality vs OEM: Build quality is slightly below genuine Echo Speed-Feed 400, but adequate for homeowner use. May have looser tolerances or plastic burrs.
• Installation: Easy – no tools needed for line loading. Remove old head, install included adapter bushings if needed, screw on new head. Takes under 5 minutes.
• Line Compatibility: Uses 0.095” or 0.105” trimmer line. Avoid thicker lines – they may jam or reduce cutting performance.
• Common Gotcha: The locking mechanism can be less durable than OEM. If the head spins freely without feeding line, the internal ratchet may have failed.

Should You Buy It

Buy this if you own a compatible Echo or Shindaiwa straight-shaft trimmer and want a low-cost replacement for a worn OEM head, especially for occasional residential use. Skip it if you trim heavy brush daily or need OEM reliability – the original Echo Speed-Feed 400 costs more but lasts longer under heavy use.
