A worn head snaps line and stops feeding
When the head cracks or the feed mechanism wears, line snaps short, refuses to advance, or jams, and you stop every few feet to fix it. A replacement bump-feed head keeps cutting without those interruptions.
- ▪ Snapped or short line. A worn head feeds poorly and leaves you cutting with bare stubs.
- ▪ Jammed feed. Old spools bind so line will not come out when you tap.
- ▪ Cracked housing. Age and bumps crack the shell so the head wobbles on the shaft.
- ▪ Constant stopping. Poor feed means frequent stops to thread or free line.
Tap to feed, cut, and keep going
The head sits on the trimmer shaft, turns with the engine, and feeds more nylon line when you tap the knob on the ground, so you keep cutting tall grass and edges without stopping to thread.
Tap the knob on the ground to advance more nylon line on demand.
Comes ready with nylon line so you can fit and cut immediately.
Open the spool, feed fresh line through, and wind it back in minutes.
Fits common straight-shaft gas trimmers; match the fitting before order.
Rigid housing with wound nylon line
A tough plastic housing holds the wound nylon spool, a rubber bump knob feeds line, and a threaded metal fitting mounts to the shaft.
- ▪ Tough housing. Rigid shell resists cracking from bumps against concrete and stones.
- ▪ Nylon cutting line. Flexible nylon wears down rather than cracking the housing.
- ▪ Rubber bump knob. Textured knob gives grip to tap and feed line.
- ▪ Metal thread fitting. Mounts firmly to the shaft without wobbling.
Remove, mount, tap, and reload
Swap the old head and keep feeding line as you cut.
Stop the engine, hold the shaft, and unscrew the worn head against the rotation.
Check the thread and adapter against your trimmer before threading the new head on.
Run the trimmer and tap the knob on the ground to advance line as it shortens.
Open the spool when empty, thread fresh line through the holes, and wind it on.

Keep line fresh and the head clean
Simple habits keep the head feeding smoothly.
- ▪ Tap gently. Lightly tap the knob on bare ground; do not slam it against concrete.
- ▪ Keep line centered. Wind line evenly on the spool so it feeds without tangling.
- ▪ Clear debris. Pick grass clippings from the head after each use.
- ▪ Replace worn line. Swap in fresh nylon before it gets too short or frayed.
It is a generic compatible head; confirm the shaft fitting, adapter, and thread match your model before ordering rather than relying on brand fit alone.

Yes, open the spool, thread fresh nylon through the guide holes, and wind it back on evenly.
