BEST BATTERY-POWERED WEED EATER BUYING GUIDE

Regardless of whether you’re experienced at using a weed eater or this is your first time getting one, figuring out how to pick a string trimmer can be somewhat troublesome. This guide should help you pick a weed eater that suits your needs. Here are several factors that you should consider before settling on a weed trimmer. 

  • Type of trimmer: There are various types of battery-powered weed trimmers in the market. Some are more powerful than others and are suited to more challenging jobs. They have different features and specifications and have different price tags. Before purchasing a weed trimmer, you must consider if it suits your needs.
  • Price: Battery power is more cost-efficient than gas over time. Your trimmer’s initial cost should depend on the use you have planned for it and your budget.
  • Line feed: As its name suggests, a string trimmer uses a line instead of a blade to cut grass and weeds. Line types vary between weed trimmers. There are three types of lines: Automatic, bumps, and manual. Automatic lines feed more line as it wears out but can be technically challenging. Bump lines feed more line when you tap the trimmer on the floor. For manual lines, you have to remove the head to re-spool.     
  • Brushless motor: Brushless motors offer more runtime, power, less maintenance, and longer life than brushed motors. A brushed motor might be sufficient for a small yard, but a brushed motor is always recommended.
  • Vibration: Battery-powered weed eaters have some level of vibration control. Some brands have better control than others. If a weed eater feels rough within the first few seconds of testing, it’s not going to offer a good experience while trimming the entire yard.     
  • Size of your yard: A battery-powered weed trimmer is ideal for trimming small yards. For a vast yard, pick a trimmer with enough runtime to handle the entire job continuously. Cordless, battery-powered trimmers can do not have enough battery power to tackle large jobs at once. You may need to purchase additional batteries to have enough power to trim the whole yard at a go. 
  • Obstacles you might encounter: You have to consider what obstacles you have to maneuver as you trim your lawn. A cordless battery powered weed eater is ideal for obstacles such as a swing set, trees, and planting beds. 
  • Edges that need to be shaped: A string trimmer can create sharp edges along planting beds, but some skill level is required when using older models. Newer models have a built-in edger that makes edging relatively easy for any user.
  • Weight: The ease of handling a weed trimmer is determined significantly by its weight. Choose a weed eater with a weight that you can comfortably and safely handle. 
  • Noise output: Battery-powered weed eaters are generally quieter than their gas-powered counterparts. However, some generate more noise than others. You should take note of the level of noise output a trimmer produces to make sure it suits the environment you intend to use it. 
  • Safety measures: A weed trimmer should have standard safety measures, including a shield over the string that prevents debris from flying dangerously. Carefully consider the safety measures of a weed trimmer before making a purchase. 
  • Runtime: Many weed eaters have a runtime of about 15 to 30 minutes. You can improve the runtime by using higher capacity batteries or a backpack battery.  
  • Connection compatibility: some weed trimmers have a universal connector that allows optional attachment heads that expand its functionality. Such attachments include a blower, edger, pole saw, mower, tiller, or hedge trimmer. A versatile weed trimmer can be handy and offer great value for money.

Safety Tips

Before using a weed eater, you must first consider the safety tips. Used wrongly, this tool can inflict injury to the user. 

  • Use Protective eyewear: Even with a shield over then string to prevent debris from flying into your eyes, you should protect your eyes with a Plexiglas visor or safety glasses.
  • Leather gloves: Wear leather gloves to protect your hands from flying debris.
  • Protective clothing: Wear a long-sleeve shirt, long pants, and boots for protection from flying debris and other trimming mishaps.

Be careful where you whack: Even with protective clothing, you must always keep an eye on what lies ahead of you as you whack.
