We had a tree services guy in to chop some enormous trees - he also trimmed the lower branches from some even bigger ones with a chain saw on a pole (not sure of the technical name). OH has a normal chain saw but this one would be so so handy for us, we have a lot of clearing to do along our river bank that would mean OH wouldn't have to get in the river in his waders and do it.
Please don't reply about courses and safety issues! Just looking for anyone with experience / recommendations for one, many thanks.
