Boreal Curing
Any one using those ryobi 40v expand it trimmers pretty light weight have mutiple attachment heads. Not as loud as the gas boys. Videos on the tube show it would fit my needs.
I use this one. It's 20v and still works fine. A 40v would handle a bush blade no problem.
And this one when I only have around a dozen or so in for seed.
Battery powered is the way to go unless you do the famous Hoypare slash and burn approach.
