Echo Spool Head Cover X472000070 for Speed-Feed 400 Trimmer Head OEM

What It Is

The Echo Spool Head Cover (X472000070) is a replacement cover for the Speed-Feed 400 trimmer head, designed to retain the spool and cutting line. It’s a direct OEM part for Echo trimmers and brush cutters using the Speed-Feed 400 head.

Fitment & Compatibility

• Specific head model: Only fits the Echo Speed-Feed 400 head (not Speed-Feed 450, 500, or other models). Check your head for “Speed-Feed 400” markings.
• OEM vs aftermarket: This is genuine Echo; aftermarket covers may vary in fit and durability. OEM ensures exact match.
• Measurement: The cover is ~2.5 inches in diameter; no other sizes apply.
• Machine compatibility: Works on any Echo trimmer or brush cutter originally equipped with a Speed-Feed 400 head (e.g., SRM-225, PAS-225, GT-225). Also fits other brands if they use the same head (verify head model, not machine brand).
• What to check: Remove the old cover and inspect the spool retainer tabs inside the cover—if broken, this part is needed. Also ensure the head’s thread size is M10 x 1.25 (standard for Speed-Feed 400).

Key Things to Know

• Installation difficulty: Easy—snap-on design (no tools required). Just align tabs and press firmly.
• Common gotcha: The cover can crack if overtightened or dropped. Replace immediately if cracked to avoid line tangles.
• Quality: OEM plastic is durable but not impact-proof. Avoid striking hard surfaces.
• Line capacity: The cover doesn’t affect line length; use .095” or .105” line as per head specs.

Should You Buy It

Buy this if your Speed-Feed 400 cover is cracked, broken, or missing—it’s a cheap, exact-fit fix that restores reliable line feeding. Skip if your head model is different (e.g., Speed-Feed 450) or if you just need a new spool (buy the spool separately).
