Overview

Meet Buckbock Speed Feed 400 Trimmer Head, a practical replacement designed for a wide range of Echo trimmers and Shiandaiwa attachments. It features a 3-3/4 inch diameter and a left hand mounting stud for compatibility with common setups. Built around the Speed Feed 400 concept, it supports fast line advancement and steady feeding through typical lawn and garden tasks. It is compatible with Echo SRM series trimmers and PAS power heads, as well as several Shiandaiwa units. Important notes: this head does not include an adapter for the Echo GT series, so please confirm your engine model and part numbers before purchasing. The mounting nut is interchangeable, allowing you to reuse your existing nut if needed.

Key benefits

  • Fast line reloads thanks to a bump feed design that keeps you moving during edging and trimming.
  • Broad compatibility with Echo SRM models and PAS attachments, plus support for Shiandaiwa units.
  • Durable construction designed to maintain line integrity through dense grass and weedy patches.

Real world use

Imagine clean, even edges along driveways and sidewalks. The 3-3/4 inch head covers a wide swath, reducing constant repositioning. In routine yard work, the quick feed helps you handle repetitive trimming without frequent stops.

Compatibility and installation tips

  • Compatible with Echo SRM 225, 210, 230, 250, 251, 260, 261 and PAS210, PAS225, PAS230, PAS260, plus Shiandaiwa models such as T195S, T220, T222, T230, and T231.
  • The mounting nut is interchangeable; you can reuse your original nut with the new head.
  • This head is not designed for the Echo GT series; confirm your model and note that no adapter is included.

Maintenance and care

Keep the head clean and inspect the mounting area for wear. When installing the Buckbock head, verify that the mounting stud matches your trimmer. A light wipe of lubricant on the drive shaft can help smooth operation over time.

Why Buckbock

If you want a straightforward replacement that emphasizes ease of use, quick feeding, and broad compatibility, Buckbock offers a practical option that supports your yard work without forcing you into a new tool family.
