Question: Where are people getting the power to charge the lawnmower?
With todays technology, when pugged into a solar panel, a lawn mower battery would charge in about 4-6 hours or 3 hours in a regular home outlet. A larger solar panel would make it quicker. Hopefully one day (by 2035) batteries will be more efficient and eco friendly and wind or solar power will be available to cover the vehicles and equipment that once were gasoline powered.
