It's not too bad mate, you can hold it out at arms length by just the handle.. I might put a strap on after. I was looking at chainsaws and hedge trimmers but couldn't find one cheap enough so i just got this strimmer. Does the exhaust muffler on yours have a bit of pipe sticking out or is it flat? Mine's flat and also aluminium so welding steel to it's not possible, i'm getting two pieces of flat bar made, one with a tube on to line up with the hole on the muffler... ill make a gasket to go inbetween aswell.
The idea is to clamp round the muffler. It might not work well but i'll see.
