Hi all,
a battery impact driver, while primarily a driver will also make light work of undoing most fasteners.
Must make sure you select the right bit that will grip securely to the head, as a stripped Phillips screw is no fun.
Some penetrant is a good precaution if it looks extreme.
The main advantage is you have great control with downward pressure at the same time as twisting off.

I recently got a Victa Charger going. Very underrated mower.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
