Cordless self-propelled lawnmower (Glen Cairn, Kanata)

This B&D is a brushed motor 36V unit used to be a powered by (heavy!) lead-acid batteries. Batteries reached end-of-life, so i tried it with Li-Ion batteries (2x20V) and it worked fine.
If you want to have it, you'll need to purchase a Li-Ion battery (& charger!) and connect to the 2 wires (easy job). I recommend a 10 Ah capacity, higher is better.
Attached photos show the name plate, side view, folded/storage option & bottom (blade sharpened and it works as mulcher only).
