I have a battery powered pole saw and weed wacker.
But I have dozens of these 70-100 foot tall dead ash.
I have 2 gas chainsaws. One for the big stuff, one for the medium stuff.
Pole saw for branches and small stuff.
That is a 24" bar in the picture. This is not one of the bigger Ash trees, just a complex one because of lean. ...
I have a gas brushcutter and hedge trimmer. That couple of hundred sq feet around this tree was cleared with the gas brush cutter. Battery trimmer would never have the capability.
I use the battery tools as much as possible, but they have very strict limits, though they get better every year or so.
Would love an electric chain saw that could do all this, and last 3-4 hours on 2 batteries.
