I thought Husqvarna used a proprietary attachment design? If they are compatible with Trimmer Plus attachments I might have bought one of power heads if I knew that. A couple of years ago I got a Troy-Bilt TrimmerPlus® pole saw attachment a few years ago off Craigslist. It was brand new with the protective plastic still on the shafts. I finally broke it in today. I found the balance when attached to my Cub Cadet 25cc 4-cycle power head to be pretty decent. I have a Portland (HF) extendable plug in pole saw which is why I hadn't tried this attachment until today and didn't feel like string out 100' of extension cord. I was impressed with the set up. I like that it has a large bar oil reservoir and it's easy to fill. The Portland is tiny and difficult to fill even with a funnel. The Portland uses a standard Poulanbar and chain which makes replacement chains easy to get. I hope the same is true for the TrimmerPlus® tool.Saw a deal on this Trimmer-Plus add-on pole saw and thought I'd give it a try. Comes with an extension bar that makes the effective length about 6 feet when fully assembled on a power head. So far I've only tried it on my newer Husqy 128LD.
