Manufacturer Part Number

A loose or broken spool cap can allow the line spool to shift during trimming. This replacement cover closes the bottom of the trimmer head and helps protect the spool and line from contact with yard debris. Check the cover for cracks, worn edges, or damaged clips if it will not stay attached. Also inspect the spool, spring, and head housing because damage to those pieces may prevent a secure fit or proper line movement. Turn off the trimmer and remove its battery before touching the cutting head. Clear away packed grass, seat the spool correctly, and make sure every cover tab clicks into position before use.

This is an OEM replacement part. It has a left hand threaded screw to remove and attach it to the trimmer head. Its purpose is to hold the spool with the cutting line, in the spool housing. It also acts as the bumper to advance the line from the spool. This is a well used and abused part of the trimmer. It may be a good idea to order an extra one.

Restore the bump-feed function of a string trimmer with this replacement feed button. Positioned beneath the trimmer head, the button contacts the ground to activate the mechanism that advances more cutting line from the spool. A damaged or heavily worn button may contribute to poor or inconsistent line feeding even when line remains on the spool. The listing is for the feed button, not the spool or full cutting head assembly. Disconnect the battery and confirm compatibility before replacement.

Manufacturer Part Number

Restore proper cutting-height support with this metric height-guide assembly for a string mower. Positioned below the mower head, the guide helps maintain the intended clearance between the cutting line and the ground as the machine moves across the lawn. Contact with concrete, asphalt, and other hard surfaces can cause premature wear, making replacement necessary when the guide becomes thin, uneven, or damaged. Stop the engine and disconnect the spark-plug wire before servicing the cutting head. Confirm fit before purchase.
