25-2 Bump Feed Trimmer Head 4002 710 2108 for Stihl FS55 FS55R FS56 FS56RC FS70 FS70R FS80 FS85 FS90 FS90R FS91R FS94R FS100RX FS110 FS111RX FS120 FS130 FS131 FS240, Replaces 4002 710 2191

Trimmer head was a good price. 10yo stihl F56 head flew apart and I couldn't find the one piece. This fit right in and works as good as the factory one. Very happy with it.

It looks and feels like a quality replacement, and works like the OEM at a significantly lower price'

Works just as good as the OEM at a fraction of the cost. The only slight difference, which doesn’t affect fit, is the bump part sticks out a little further than the OEM, or my OEM original was just that far worn down. Installation is easy, there’s a small hole in the trimmers head (may be hidden and plugged with dirt and grass as in my picture), stick a small screwdriver in that hole, rotate the head by hand until you feel your screw driver catch. Unscrew the plastic head by hand, NOTE: It’s a “reverse thread”, meaning you turn it counter clockwise to loosen, clockwise to tighten. Hand tight is all you need, it tightens itself from the direction of its rotation. There’s a bolt head on the opposite side of the hole, its there so you can shoot some grease into the head. If you’re having to replace the part being reviewed its probably already past time to put some trimmer head grease in there. The couple reviews I read of people complaining this replacement “sticks” need to use a little common sense. The OEM ones could stick sometimes as well, the solution is simple. When you take it apart to wrap more string clean the dirt out of it for one thing. You can also take sand paper and smooth out around the bump mechanism and the inside of the hole on the outer cover, common sense, until it works smooth and freely.

A great stihl replacement

Cheaply Made. Don't buy. Difficult to put on because of the incorrect indentations inside. Goes on one way, period. Weak spring. Doesn't feed properly. Worst trimmer head I've ever used. Not for heavy duty use. I finally threw it away. Bought a real US made Stihl trimmer head for my Stihl brush cutter. Don't go cheap. You will regret it.

Direct replacement for my Stihl trimmer. So far it works great. The string that comes with it isn't the strongest and gets burned through fairly fast, but it works. I reloaded with my usual string and works great. Seems pretty sturdy

After years of service, my whip's head shattered when tapped for more strong. Bought this, threw it on in a matter of seconds, and went back to work. Affordable and effective, just double check your part numbers to be sure it will fit. It came with string in it!

worked on my weed eater

Its ok for a cheap replacement

Connected fast and easy. Works really well. Very happy with my purchase

nice trimmer head for a fraction of the original so far so good we will see how long it will last

Trimmer head fits perfectly, operates just like original

Do not buy!! Cheaply made. Eyelet sleeves do not fit snugly and can easily be lost and I only received one sleeve. Must contact Amazon to return and I've been in the phone queue for 90 minutes and counting.
