When was the first electric mower used . I recall one in the 1950's , I never used it but I have the switch of one of about that era that turns my old table saw on and off . I thought it appropriate because the T S is a 1947 Sears Roebuck that I can turn on and off with my knee .
Many of the Lithium-ion battery powered mowers are still going strong after years of service. The trouble is, many of the batteries cost more to replace than just buying a new mower.
Aside from that, all batteries have a limited number of charge cycles before they are depleted.
The level of recycling and ground contamination from this new "green technology" is still yet to be determined.
