Hi! My name is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today I would like to talk to you about the proper use and maintenance of a yard weed eater. Let's take a moment and talk about the different types of weed eaters. We have one that is gas powered with us here today. We also have an electric weed eater. There is really not much difference other than the gas powered is typically more powerful than the electric and also have a larger head. You can cover more surface with the stronger gas powered one than with the smaller electric. But they both operate pretty much the same principle. They have a line that comes out of the head and the head spins rather quickly and as you run it by grass or weeds, it cuts them down. This gas powered model here, some are affixed. The gas powered one is all one unit. It is a weed eater. This particular model is interchangeable. These ends will come off and I can turn this weed eater into an edger, turn it into a hedge trimmer. There are various other attachments that you can add to the machine. This comes in handy rather than having to own two entire units. I only have one unit with interchangeable heads.
