Pros: Great for light limb cutting.
Cons: Not heavy duty enough for everyday use. chain comes loose to easy.
I got this attachment for light yard work, trimming branches that were out of reach.
This trimmer will attach to any brand that uses the "shaft attachable" devices.
This includes Husqvarna, Ryobi, Crastsman, Poulan, some John Deere, etc.
Attaching is simple. You just unscrew the old device locking knob, pull off the device, slide this one on, and tighten the knob back down.
If you want a longer reach this one also came with a 3'ft extension, but I found that having two joints in this wasn't near as strong as the fancier brand ones that are a single straight thicker shaft. (of course those cost three times as much also).
Just crank up and use. It will cut branches that are several inches thick.
As a reccomendation, because limbs that are cut will sometimes hang on the "bottom bark" under the limb and might swing and hit you, before you cut the limb, take the saw and give a slight cut to the bottom of the limb first, this cuts away the bottom bark. That way when you cut from the top and it cuts all the way through, it'll fall clear of the tree and not swing and hit you as the operator.
As an added benefit, if I need to cut a normal limb that I would have otherwise used my normal chain saw on, it's nice to be able to use this one since I've already got oil/gas in my weedeater and I don't have to break my chain saw out of storage and gas/oil it up and then winterize it again when I'm done.
Basic maintenance is keeping oil in the lubricator, keeping the blade tight, and sharpening the blade.
I've not had to change my blade yet, but it changes out just like a normal chain saw blade. You can change it out with an box end wrench and a screw driver to tighten.
I did find that the blade looses a good bit with use. I found my self having to re-tighten it often. (more often than I think you should have to with a product like this).
Just take it off the weed eater and store with the rest of the garden tools. Make sure you keep the oil resivoir upright as it will leak out a little. Just makes a mess when it happens is all.
Where to buy:
At Home Depot, Lowes, Ace Hardware or any store on the web that sells weed eater attachments:
Great for homeowner use in the backyard. If you want it for heavy duty use, I'd reccomend a dedicated model that is stronger.
