Would you feel comfortable using this 100% electrically propelled homemade "device" to mow your lawn? With you immediately behind pushing it along?? From the notes I have on file it took its "creator" to build in just seven hours. From absolute scratch. I do not know exactly when this photo was taken. However it was devised "way back when" and I think it may be probable this contraption had little to do with the advancing stages of electric lawnmower chronology of yesteryears....
