What It Is

This is a 3-pack of aftermarket universal trimmer heads designed to replace OEM Echo Speed Feed 400 heads. They are for gas straight-shaft trimmers, bump-feed reloading, and .095-inch or smaller line.

Fitment & Compatibility

Check your trimmer model against the list: Echo SRM-210, SRM-2100, SRM-225, SRM-230, PAS-210, PAS-211, PAS-225, PAS-230, PAS-260, and Shindaiwa T195S, T220, T222, T230, T231. These are for straight-shaft models only—curved-shaft trimmers use different heads. Measure your output shaft diameter (typically 10mm or 7/16-inch for these models). Each head includes a universal adapter plate and three different-sized center holes to fit most straight-shaft spindles. If your trimmer uses a specific locking pin or tool, you’ll still need that for installation.

Key Things to Know

• Quality vs OEM: These are aftermarket, so plastic quality and tolerance may be slightly looser than genuine Speed Feed 400. Some users report the bump-feed mechanism can be less consistent.
• Installation: Simple—remove old head, slide on the adapter, align the center hole, and tighten. No special tools beyond a spanner or pin (not included).
• Line Loading: Uses pre-cut line or spool reloading. Bump-feed works, but you may need to tap harder than OEM for line release.
• Common Gotcha: The adapter plate can crack if overtightened. Hand-tighten plus a quarter turn is enough.

Should You Buy It

If you own one of the listed Echo or Shindaiwa straight-shaft trimmers and want a low-cost backup or replacement for a worn OEM head, this 3-pack is a solid value. It’s not for professionals needing zero downtime or perfect feed reliability, but for homeowner use or occasional trimming, it works well for the price.
