Anyone got a specific brand of battery-powered lawn mower and love it? My twenty-year-old Enviromower is losing its strength and it might be time to replace it; spare parts are unobtainium. Battery power is non-negotiable.
@futzle the most likely reason for it losing power is worn bushes. Just replace the bushes and it'll keep going for a few more years https://ebay.us/m/j6j0Mc
