MartinGZ:martyyn:... I decided to replace it with a much more powerful Makita and dual line feed. It rips through everything now and is what I should've bought in the first place.
I'd be interested in what model it is, how powerful, and what runtime you get. My Stihl (petrol) is near the end of its life, so I'm browsing the market. Typically when I bash the weeds I'll be doing 2-4 hours at a time and the going is pretty heavy. Often I don't just cut, I clear them right down to bare soil.
That 2-4 hours - is that because your current petrol version isn't grunty enough to take bigger cuts in less time, or simply the expanse that you are trimming?
