Trimmer Head Replacement Spool for Echo Genuine OEM Speed Feed 400, Cover for SRM-225, SRM-230, PAS-225 Trimmer Heads (5 Pack) / X472000070

What It Is

This is a 5-pack of genuine OEM Echo Speed Feed 400 replacement spools (part X472000070) with pre-wound trimmer line, designed for Echo trimmers and brush cutters that use the Speed Feed 400 head assembly, including SRM-225, SRM-230, and PAS-225 models.

Fitment & Compatibility

• Confirmed fit: Echo SRM-225, SRM-230, PAS-225 (and any model using the Speed Feed 400 head)
• Check your head: Verify your trimmer has a Speed Feed 400 head—look for the “Speed Feed 400” label on the head or in your manual. This spool is not compatible with Speed Feed 200, 300, or 450 heads.
• OEM vs aftermarket: This is genuine Echo OEM, so it matches factory specs exactly. Aftermarket spools may differ in line diameter or thickness—use only .080″ to .095″ line as specified.
• Measurements: Spool outer diameter is approx. 2.75″; line length per spool is about 20 feet. Confirm your head’s line capacity matches.
• Not universal: Does not fit non-Echo heads or older Echo models with different head designs (e.g., Speed Feed 350).

Key Things to Know

• Installation is tool-free: Push the spool into the head, rotate to lock, and thread line through the eyelets. No disassembly required.
• Line is pre-wound: Each spool comes with line already installed—just replace the old spool. No winding or measuring needed.
• Common gotcha: The spool may sit slightly loose if your head is worn or damaged. Check the head’s retaining tabs for cracks before installing.
• 5-pack value: Buying a multi-pack saves time and shipping costs compared to single spools, but ensure you’ll use all five before the line degrades (store in a cool, dry place).

Should You Buy It

If you own an Echo trimmer with a Speed Feed 400 head and want zero-fuss replacement spools that match OEM quality, this 5-pack is a smart buy. It’s ideal for frequent users who want to keep a spare on hand and avoid winding line. Skip it if your trimmer uses a different head or if you prefer buying line in bulk and winding yourself.
