Yes the one the council used last Thursday was on a large truck and
powered by a powerful engine, and was extremely noisy. If you have a
lot to do hiring one of those for a couple of hours might be the best
approach, but give your neighbours ear plugs first..

I hired an electric one for half a day that was pretty quiet and
handled largish branches with ease while not clogging with the small
green stuff. The cheap one I got (can't remember if it was dirt cheap
on eBay or free from Freegle) makes a load of noise, struggles with
larger stuff and clogs easily with green stuff. The difference is that
the good one runs at low speed and pulls wood through and chomps it,
while the crap one is just a spinning disc on a motor and you have to
shove stuff through to feed it.
