Husqvarna 115H! It's down to like $600 now. This is going on its 3rd year doing my backyard, and its fking amazing. Once a month I trim the perimeter, but otherwise I dont have to mow most of my yard now, its always the same perfect height, the grass seems much happier with it too.
Up until last year I didn't even know people in my country even still had petrol lawn mowers. I wanted to get one of those things that's not even powered, just a rolling blade cage.
