There are several different options on weed wackers now days and they are called by a number of different names. String trimmer, line trimmer, and weed eater are just a few. If you are in the market for any of these trimming devices; please pay attention as I am about to point out some of the major features.
Best Weed Wackers
Depending on how large your yard is and what types of weeds you will be cutting down you can choose between a gas and electric weed wacker. Electric weed eaters are often times cordless and run off of a battery. You will need to keep charge and use time in mind when buying an electric cordless weed eater. A good battery and charging system should allow you at least 30 minutes of trimming time. Keep in mind that in use time will go down after the battery has been charged several times over. Electric weed eaters are generally used to small areas of grass and do not have the power to take on thick weeds or brush. On the up side electric grass trimmers are light weight and easy to handle. Electric weed trimmers are also extremely quiet for those living in a small subdivision.
Gas Weed Whackers
Gas weed wackers come in two types of engines ranging in sizes measured in ccs. Commercial weed trimmers run in the 30cc range and can be 2 or 4 stroke engines. 2 stroke weed eater engines will need a mix of gas and fuel. This means you will have to premix your gasoline with oil in a predesignated gas can before fueling your gas powered weed wacker. If you have a commercial engine which is 4 stroke you need to add gasoline and oil separately. Gas powered string trimmers in the 20cc engine size range are perfect for homeowners with larger property area. Most customers report their gas weed wacker running for more than two hours on a single tank.
Before making your final decision on any weed eater or weed wacker you should always take a look at the available attachments for your unit. This can increase the value of your new yard tool even more. Common weed wacker attachments include edging and hedge trimming attachments. Some companies such as Husquvarna have created a while line of attachments meant to be used with their string trimmer motor.
