Inspiration At The Car Wash
In 1972 inspiration strikes Houston businessman, George Ballas, while at an automatic car wash. As George watched spinning bristles clean his car without damaging it, he wondered if he could use the same principle to trim the grass around his trees' trunks without damaging the bark.
Rushing home, he found a tin popcorn can in the trash, punched holes in it and inserted fishing line to simulate the car wash bristles and attached it to the rotary on his lawn edger. Within seconds, the spinning lines neatly sliced thorugh the grass. He knew he had found the answer to his prayers and millions of others.
