Weed Eater was a string trimmer company founded in 1972 in Houston, Texas by George Ballas, the inventor of the device.
The idea for the Weed Eater trimmer came to him from the spinning nylon bristles of an automatic car wash. He thought that he could come up with a similar technique to protect the bark on trees that he was trimming around.
His company was eventually bought by Emerson Electric and merged with Poulan. Poulan/Weed Eater was later purchased by Electrolux, which spun off the outdoors division as Husqvarna AB in 2006.
