I’ll jump on the ‘don’t discount leccy’ bandwagon.
I’ve a collection of Stihl and Husquavana garden flavoured man jewellery, all hairy chested petrol powered. I bought a Stihl HSA26 battery hedge trimmer that (as above) looked and sounded like a toy. It isn’t.
It’s light enough for SWMBO to use and heavy duty enough to cut the many, many metres of Leylandii that blesses our garden. A battery lasts about 40mins which is about the time it takes to give the arms a rest and clear up some debris. With a spare battery, you can cut continuously if you wish as they recharge within the discharge time.
It won’t chomp through really thick stuff but copes with 90% of what we need and the bonus is, MrsBoblo can now trim her own bush(es).
