Not a direct answer, but I am in a similar situation.
I got a short blade 'ditch' scythe, and an Echo battery string trimmer/brush saw.
I wanted those tools for a woodlot, and they let me keep the grass down in the interim while I convert to vegetable beds, berries, nuts and fruit trees.
I dislike the microplastics from the string trimmer, so am moving to use it mostly with brush blade.
