XQK Spool Cover for Echo Speed Feed 400 Trimmer Head — 6-Pack OEM-Style X472000070, Durable Wear Caps

The XQK X472000070 spool cover is a six-pack replacement cap designed to fit Echo Speed Feed 400 trimmer heads, restoring secure line retention and protecting the spool from debris.

When your Echo Speed Feed 400 trimmer head has a worn or cracked spool cover, the result can be poor line feed and premature wear of internal parts. This XQK pack supplies six OEM-style replacement covers (part number X472000070) so you can service multiple machines or keep spares on hand. Each cover replaces the outer wear cap only; springs and inner caps are not included.

How do I know this cover fits my trimmer head?

This cover is made specifically for the Speed Feed 400 family and matches the X472000070 specifications. It’s slightly different in size from the Speed Feed 375, so confirm your head model before ordering.

• Part number: X472000070—exact match for listed models.
• Compatible with Echo SRM-225, SRM-225i, SRM-225SB and SRM-225U variants shown in the product details.
• Not interchangeable with Speed Feed 375 due to different dimensions.

What’s included and what do I need to reuse my current trimmer head?

The package contains only six spool covers. If your original spring or spring cap is damaged you will need to source those separately. Installation is straightforward for anyone familiar with trimmer head maintenance.

• Included: six XQK spool covers (wear caps) for Speed Feed 400 heads.
• Not included: spring and spring cap—reuse existing hardware or buy replacements.
• Tools: typically a flat screwdriver or small pliers to remove and reinstall the cover.

How does replacing the spool cover improve trimmer performance?

A fresh wear cap keeps line spooling smoothly and prevents dirt and grass from entering the head, which reduces jams and uneven feeding. Replacing cracked or warped covers restores correct line tension and helps prolong the life of the trimmer head.

• Reinstates proper line retention and feed behavior.
• Shields internal components from debris and moisture.
• Prevents further wear that can cause costly head replacement.

Can I install these covers myself and how durable are they?

Yes—installation is a simple, low-skill task for most users. The covers are manufactured to OEM-style dimensions and durable enough for regular trimming duty, though replacement intervals depend on use and environment.

• DIY-friendly: removes and snaps on using basic hand tools.
• Built to OEM-style tolerances for a secure fit on Speed Feed 400 heads.
• Durability: reliable for routine residential and light commercial trimming; inspect periodically.

Who is this for? Landscapers, property owners, and maintenance teams who use Echo trimmers with the Speed Feed 400 head and prefer to keep simple, cost-effective spare parts on hand will benefit from this six-pack. It’s ideal for servicing multiple machines, stocking a repair kit, or extending the life of a single trimmer head without buying a full replacement. If you need the complete head rebuild (including springs or caps), source those parts separately; otherwise, these XQK covers are a practical, OEM-style option for routine upkeep.
