Instead of using the usual secateurs to cut the laurel hedge twice a year,
we're planning to invest in a mechanised hedge cutter. The hedge is at
least 30ft x 6ft high and runs round some of the garden, with pavement on
the other side.

Does anyone have any advice - ie what would be best for the job? I imagine
one without a flex would be better, but I don't really know. Are there some
to definitely avoid or beware of? Are there small ones, large ones, light
ones, heavy ones?

I'd be very glad of some advice on this as I'm a real beginner as regards
hedge cutters. Thanks.
