If you're looking for a multi attachment set up you can interchange with other brands.

With my rover 2700 trimmer i have a rover edger and a no name ebay hedge trimmer,i can fit a no name saw if i want too or what ever i need.

The only info i need in purchasing any attachment is buying a 26mm outer pole and a 5mm square shaft.So it leaves it wide open in replacing the power head or any attachment without costing mega bucks.

So with your brand if you have those measurements then you can order the parts you need,ofcourse your unit may have a 5 or 7 spline.

heres a good demo
