Weedeater - Well, this is a new one

Bought a replacement bump knob and spool because my current knob was broken and I liked the design of the replacement spool. Get about an hour into weedeating, everything working fine and smooth. Then, I noticed that when I bumped the knob on the ground the trimmer line was not extending. hmmmm....maybe grass was clogging up the head.

Nope, the MOTHERFUCKING bumper knob had welded itself to the MOTHERFUCKING spool. That's right, apparently there was enough heat from the rotation of the trimmer head, that it melted enough plastic of the bulb and then cooled down long enough that the two pieces sealed together. Can't take off the bumper knob to get to the string. No amount of wrench torque is able to twist the pieces apart. UN-MOTHER-FUCKING BELIEVABLE. Trying to find my hacksaw now.
 
I just bought a 4 cycle weedeater with a hassle free head. It has the powaaahhh.

Feels like it is going to slap the wood off my fence.

I have Troy Bilt 4 cycle. Engine has been great. Trimmer Head and Bump not so much.

Oh, and stop hijacking this thread by arguing what it's called.
 
I've actually had good experience with the battery-powered ones, usually 18-volt LiIon or higher. Good power and life, virtually no maintenance. would never buy a gas powered trimmer personally. had corded electric ones in the past, but it's a pain dealing with the cord.
 
Current knob was broken. Too much friction on new knob.

The plastic tabs and screw mounting holes on plastic motorcycle bodies (crotch rockets) get broken off, and some guys try to use plastic weld to put them back on. I'm guessing it's hardly every successful.
 
If it heated up enough to melt and then lock as cooling, try to heat it up again and then separate the two as the plastic softens.

Alternative would be to soften up the joint using a torch at low power.

Are you sure that it was the heat from the unit and not the Texas heat 😛

Good point. If's f'in hot out today, but I have so much outdoor work to do. Going out with the daughter in a few minutes to trim a tree. Then, there's an issue with my pool's electrical. The breaker keeps popping. And of course, since I just weedeated around the pool there's grass in there I have to scoop out. Sigh...it's never ending.
 
Most quality weed eaters will have a metal band around the motor housing 😛


I've been using how long the engine is guaranteed to meet emissions requirements as an adjunct for determining engine quality/durability. The EPA requires gas trimmers meet emissions standards for 50 hours. Better trimmers will advertise their motors will meet those standards for 125 hours, like with some Toro models, or even out to 300 hours, like some Echo, Stihl and Hitachi models.

And I think dual line models merit much higher consideration for purchase these days vs. the bump feed type trimmers.
