Question about Troy-Bilt 4-Cycle Curve Shaft Gas String Trimmer #41ADT41C966
Check gear head for grease and i have turned a lot of customers onto a speed-feed head i have had great feed back on them. They have 2 different heads but will fit almost all trimmers. One fits curved shaft and the other fits only straight shafts. You can google www.speed-feed.com look at video and how much it will help in respooling the head. I use it personally as well.

Check the size of the line,(OD), make sure you are using the correct size, sometimes cheap line will be problematic, also, you said you are re-stringing it, try a new batch of string, the old string inside the hub can get chaffed and will stick to itself...

hey! I just had the same thing happen to me 30mins ago. I tried prying it off with a screw driver and punching it out.No such luck. Frustrated, I tried turning the spool from the base and it popped right out and I was able to easily disassemble.

I didn't find that exact one either, but recently had to work on my Yard Man 4-Cycle Straight Shaft and used a Troy-Bilt manual for a similar trimmer - worked great.
If you don't find yours at this site, maybe a similar one will work. It looks like the difference is the TB525 receives attachments. If you're trying to fix something right now, here's the manual for that one until you find yours:

This model trimmer uses .095" diameter line, your local home improvement store will carry replacement line and it will also carry a replacement spool with the line already spooled on it.
This trimmer is a "bump advance" trimmer meaning you bump the head on the ground while it is spinning to advance line out.
What to do to replace the line is place the trimmer on a stable flat surface (like a workbench), raise up the head if the trimmer and unscrew the cap and CAREFULLY remove the spool...you do not want to lose the spring! Take a look at the spool, it will show the direction to spool the line, spool the line then replace the spool by first putting the spring back on the shaft, then put the end of the line through the hole(s) on the side of the outer head, press the spool in place and screw the cap back on.
Of course you can eliminate about 90% of the headaches by buying a pre-spooled head at your local home improvement store...then you follow the directions above and can skip the spooling part. Cheers!
