Weed wackers have become as common a tool for lawn maintenance as the lawnmower. There are various brands and models as well as features and attachments for weed wackers. Because of this, you must compare weed wackers to ensure you gain the best options and features for your needs. Having the right trimmer for your lawn will help keep a maintained and professional-looking lawn.
Determine your budget for the weed wacker. Trimmers vary in cost depending on the type purchased. Battery-operated trimmers are generally the cheapest while electric corded trimmers are slightly more expensive. Gas engine weed wackers are the most expensive to purchase and maintain.
Look at the shaft. The shaft is the metal rod between the trimmer head at the base and the engine up top near the handle. There are three styles of shaft handles: straight, curved and split. Choose a shaft according to your needs. Curved shafts have a curve near the trimmer head to accommodate even trimming work near edges and over low objects. Straight shafts are used for heavier brush and better access underneath tall items. Split shafts can accommodate various attachments such as blowers or blades.
Determine the amount of power you will need for the lawn. Cordless trimmers have the least amount of available power since they are run off of batteries; these must be plugged in at the end of each use to recharge. Corded weed wackers have more power since they run off of a constant 110-volt power supply but do have limited cutting power and are useful only on grass and thick weeds. Gas-powered engines offer the most power and can cut anything up to small brush.
Identify the time limitations for the power supply. Battery trimmers can run only 20 to 60 minutes on a consistent basis before needing a recharge. Gas-powered trimmers run from 30 to 90 minutes constantly depending on the size of the tank.
Compare power rating and size. Higher amps and larger engines provide more power to cut but also use more power to operate the trimmer. Electric trimmers range from 12 to 18 volts while gas engines range from 20-cc to 31-cc; cc refers to cubic centimeters of air displacement. The higher power also uses more electricity or fuel to run them.
Examine the features of each weed wacker. Weed wackers come with a variety of attachments and accessories. Automatic cord extenders are found either on the handle or as a button under the trimmer head. Auto shut-off triggers and push-button starting are other features. Extended safety guards and deep trimmer wells are good for safety and efficiency. Sure-grip handles reduce vibration and ease wear on the hand.
