A line trimmer, also known as a string trimmer, is used to trim grass or weeds. The piece of equipment also goes by the name of a weed eater, or weed whacker.
To effectively remove grass from concrete surfaces, you can use a combination of tools and methods such as a weed trimmer, a scraper or putty knife, and a weed killer spray. First, trim the grass with a weed trimmer to make it easier to remove. Then, use a scraper or putty knife to scrape the grass roots from the concrete. Finally, apply a weed killer spray to prevent regrowth.

You remove the bottom cover off the weed trimmer, and remove the tangled old wire. Insert the new wire into the side of the trimmer and wrap it around the black spindle.
I purchased my Toro weedeater in 2007. It uses a 50:1 gas/oil ratio.
