CMOOD Trimmer Head Replacement for ECHO Speed Feed 400 — 3-Pack Straight-Shaft Bump-Feed, 3-3/4" Diameter

CMOOD Trimmer Head for Echo Speed Feed 400 SRM-225 Weed Eater Head is a 3-pack of straight-shaft replacement heads engineered to drop into compatible ECHO SRM models for fast line feeding and reliable field performance.

Replace worn or damaged bump-feed heads without buying a new unit. This CMOOD assembly is designed to fit a wide range of ECHO straight-shaft trimmers (SRM and PAS series) and works as a direct swap for Speed Feed 400/375-style heads. Each head measures roughly 3-3/4" in diameter, installs quickly, and is supplied in a set of three for immediate back-up and reduced downtime on the job.

Which Echo trimmer models will this head fit?

This CMOOD trimmer head is built specifically for straight-shaft ECHO trimmers. It replaces several factory Speed Feed part numbers and lists broad compatibility across SRM and PAS model families. It is not compatible with curved-shaft or non-ECHO models unless those units share the same straight-shaft Speed Feed interface.

• Fits SRM series: SRM-225, SRM-210, SRM-200, SRM-230, SRM-250, SRM-265, SRM-266, SRM-280, and related variants.
• Fits PAS series: PAS-210, PAS-211, PAS-225, PAS-225VP(B), PAS-230, PAS-231, PAS-260, PAS-261, PAS-265, PAS-266, PAS-280, PAS-2100, PAS-2400, PAS-2601.
• Designed as a replacement for Speed Feed 400 / 375 bump-feed heads.

How easy is installation and line loading?

Installation follows the same steps as the original Speed Feed head, so if you’ve changed a trimmer head before, this will be familiar. The bump-feed design lets you feed line quickly by tapping the head on the ground while the trimmer spins at low speed. No special tools or adapters are required for compatible straight-shaft models.

• Quick off/on swap—use basic hand tools if needed to remove old head.
• Bump-feed mechanism for fast line extension while working.
• Pre-sized for the common line diameters used with these heads.

What are the build quality and key specifications?

The CMOOD head is manufactured from durable materials to withstand normal landscaping use. With a nominal diameter of 3-3/4", it matches the footprint of common Speed Feed 400 heads. The package includes three heads so you can replace a worn head and keep extras on hand.

• Nominal diameter: 3-3/4" for proper fit and balance.
• Durable molded components designed for repeated bump-feed action.
• Sold as a pack of three; includes limited 6-month warranty service.

Are there any fit cautions or exclusions I should know about?

This product is intended strictly for straight-shaft trimmers; it will not fit curved-shaft models. Before purchasing, compare your existing head to the photos and compatibility list to ensure the attachment interface and diameter match. If you have a non-ECHO trimmer, confirm the shaft and head interface are identical to avoid mismatch.

• Not compatible with curved-shaft weed eaters or non-matching interfaces.
• Verify part fit by comparing your current Speed Feed head to product images.
• Contact seller support for model confirmation if uncertain.

Who is this for? Landscapers, homeowners, and maintenance crews who use straight-shaft ECHO trimmers and need an economical, ready-to-install replacement for worn Speed Feed heads will benefit most. The three-pack format suits users who want spare units on hand to reduce interruptions, and the straightforward installation is ideal for people comfortable performing basic trimmer maintenance.
