Size

• Size is an important consideration when choosing a weedeater. To ensure a weedeater is comfortable, pick up different weedeaters to determine the particular style and size easiest to hold and use. Also, be sure you can easily lift and carry it. According to the website GrassTools, the cordless weedeaters are generally heavier than corded ones and can weigh up to 15 lbs. On the other hand, corded weedeaters only weigh about lbs.
  
  

Types

• The three types of weedeaters are electric, battery-powered and gas-powered. Electric-powered models need an extension cord long enough for an adequate range. Some of the latest battery-powered models contain rechargeable battery packs, allowing users to use a weedeater without an extension cord but it's still good to buy additional batteries for more power supply when doing larger yards. Gas-powered weedeaters are best for cutting tall grass because their motors are more powerful.
  
  

Blades

• Weedeaters have either nylon cords or plastic blades. Both choices are rather inexpensive, however the nylon cord type needs to be frequently replaced with each use. Nylon cording comes in various widths. As different weedeaters require different sizes buy the right size for your particular edger.
  
  Plastic blades have a downside because they can easily break when they're used to cut grass or weeds growing against a hard surface such as a driveway.
  
  

Considerations

• Hold your weedeater at a 30 degree angle for best results because it helps cut grass edges at the same levels as the rest of the grass, notes GrassTools. Cutting grass shorter on the edges gives an unprofessional look to your landscape. Use slow, sweeping, smooth motions when operating your machine. Complete all edging after mowing the lawn to ensure uniformity.
  
  

Warnings

• Always wear safety apparel, including goggles and long pants when using a weedeater. Because the spinning motion of the tool can pop stones, rocks or grass debris into the air, wear gloves for protection. Periodically take breaks to avoid muscle strain. Keep weedeater lines at uniform lengths. The lines should be long enough for effectively cutting weeds
