Most trimmer heads are cross threaded, so its opposite of normal threads. you have to turn it clockwise to loosen it. also try soaking it with penetrating oil

Trimmer head will not stay connected to shaft

Should be reverse threaded so that the rotation tightens it. However it could also be missing a locking nut or pin.

Cannot remove spool

Take a look at the cutting head, when you spin it around do you see two holes line up on the side? If you do you have to put a rod in the hole (an allen key or Robertson screwdriver would work too) and spin the cut head nut off in a clockwise direction.
So as it's upside down look down on it and turn it to the right....yeah normally that would tighten it but to keep the head from flying off it's a reverse thread. This is common on the ends of small engine shafts too.
The nuts are reverse thread and if you really try to loosen it you end up stripping it...because it's backwards.

Good luck.

My poulan pro trimmer has no nut on the head to remove it. it has a screw inside. how do i work that. the screwdriver wont hold it.

See page 13 of your manual here for removing the head. Please realize that the head has LEFT_HANDED threads on it (not the conventional R-handed) so you have to turn it to the RIGHT to loosen and remove it.

Just bought a brand new Husqvarna 224L Trimmer. Started it up and it runs fine. But the trimmer head will not turn. It just makes a grinding noise. The manual that came with the trimmer is useless. It says...

Hi, take it back to the dealer as the powered or gear box have not been fitted correctly. The noise you can hear is most likely the clutch drive grinding on the drive shaft. Hope this helps, regards Phil.

I have a Lawn Hornet RLH 1100 Mk II. I have owned it for about 20 years. I need to replace the cutting head and wanted to know if the Reel Easy LTA 042 would be a suitable replacement. John A

Hi, I have the same machine as you and I also needed to replace the head. I purchased the reel easy head and found out that it does not fit the lawn hornet because the head has a tapered end and it does not provide enough clearance against the bushing housing. I did eventually get it to fit but I had to spend a while machining the housing on a lathe. It's a great head and worth the effort but it is very difficult to fit. Cheers

I have a TB525EC trimmer with the "new" string

Great question! You can always go to the Home Depot and purchase a "universal-type" retro head and if it doesn't fit correctly, just return it for a refund or go on a site like Ebay and buy a genuine Troy Bilt retro type string head. I bet they will fit.

I am searching for a line quick-change head for a Husqvarna 125L. I'm tired of winding line every 5 minutes. Can't find anything in stores or on-line. Any suggestions?

Do an online search for "Kwik Loader" They are sold by MANY outlets,,, Oregon Outdoor Products to name a few. You pre cut lengths of line and when they wear down, you slide the end pieces out through the center and insert a new line. They come with many different adapters and fasteners to fit 99% of the trimmers in use today

Look at the top of the head (where the brush cutter is) find the small hole about 3/16 diameter. Insert an allen wrench or a large nail, or anything else that will fit in the hole almost the same size as the hole. While putting a little downward pressure on this "tool" turn you blade slowly by hand until you feel the tool slide into the locking slot, this will hold the blade from turning. Keeping it in this position, take a socket and ratchet on the nut that is holding the blade and loosen and remove it. THE NUT HAS LEFT HAND THREADS SO TURN IT OPPOSITE OF WHAT YOU NORMALLY WOULD TO REMOVE IT!!!!
