This is not new....Electric lawn tractors, compact tractors and even large tractors have been tried for decades..for various reasons they never caught on..cost and battery issues/technology being the main problems.... If you research the all electric vehicle industry as it stands right now "with unbiased facts and stats" the truth is that electric cars on average have somewhere between 30&40% more issues and problems than gasoline/diesel powered. Also the dangers of LION batteries is just now starting to show itself...fires, explosions, toxic gas, etc, etc, etc. The firefighting world is one of the best places to find out about the true dangers and how they are becoming more and more common. That said..sure an electric tractor might be nice and fun for certain things..But all things considered I beleve that a world powered by batteries is not going to happen in any massive scale for many years to come....In all truth there is no such thing as "Green Energy"... It all has to come from the ground at some point....name one thing we use and consume that doesn't.
