OK so I may be pushing my luck - I've had such great advice here that I'll chance it..
I've a monster privet hedge that needs 6 feet off (height) and 4 feet (depth) as well as holly, 12 foot beech hedge that needs a haircut, a small length of leylandii and about 20 feet of small leaved evergreen hedge. I don't think a cordless hedge cutter will have enough oompf. I hate corded things. I'm thinking petrol. Hedge trimmer or chainsaw ? Brand ? Model ?
Any advice gratefully received. I could get someone to trim the privet back and then try and stay on top of it I guess. But I've still got the other hedges to do.
