Weed Eater

Weed Eater was a string trimmer company founded in 1971 in Houston, Texas by George C. Ballas, Sr., 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.
