Has anyone used one? I have a "new" garden (it's well established) that
has various nooks and crannies of lawn. Trying to cut the grass dragging
an electric cable (more to the point having to avoid it when reversing out
of a nook) is trying. I've been and at looked at petrol mowers but (a)
they're expensive (not that this is that cheap) and (b) I'm no mechanic and
previous experience with a petrol driven rotovator was not terribly happy.
