To Bump or Not to Bump?

Cleaning up your yard is a lot easier with a string trimmer. Thanks to improvements in battery technology, a cordless string trimmer can save you from dragging around long extension cords or remembering which gas can is for the two stroke engine. Check out the features on the products listed below, and you'll know more about the best cordless string trimmer 2017.

Picking the Best Weed Wacker For Your Yard

String trimmers work by spinning a multi-edged high density plastic piece of string very fast so it will cut whatever greenery it brushes against. If you're just trimming grass along a sidewalk, driveway or fence, a single-string head will likely serve your purposes and save you reloading string.

However, if you've got a lot of brush to clear or an especially large yard, a double string head will be faster. As the string gets worn away it advances, so eventually you'll run out and need to reload the tool. Carefully review your manual to make sure you get the right cutting string and load it correctly so it advances. If you're not comfortable with learning this process, you can buy new, pre-loaded heads for many tools. This may be more expensive, but the best cordless string trimmer is the one you can use quickly, not the one hanging in the garage with no string remaining.

Safety Considerations

No matter which string trimmer you select, there are some basic safety considerations to review and put in place before you use this tool. This video offers several great safety recommendations for using your string trimmer.

  • 1) Protecting Yourself: Wear long pants. String trimmers spin quickly, and some of what you cut away will come back at your legs. Additionally, string trimmers can pick up stones, mulch and other hard objects and toss these around as well, so eye protection is a good idea.

    Finally, string trimmers vibrate. If you're doing a quick ten minute trim of your yard, this may not be problematic, but most batteries are rated for an hour. Chatter resistant gloves can protect the nerves in your hands and arms from eventual damage.
  • 2) Protect Your Loved Ones: Children should not be allowed near lawnmowers and string trimmers as they may come into the path of grass clippings and debris. Yard tools will throw hard objects they come in contact with, and if you're working with a tool you probably can't hear anyone coming up behind or beside you.
  • Protecting Your Belongings: Put your car in the garage. If you're trimming along a sidewalk near the house, check the edge for stones. String trimmers will pick up and throw what they can't cut, and small stones can wreak havoc on home and vehicle windows.

Weight and Length Consideration

Time of use is critical when determining which string trimmer will suit your setting best. The heaviest string trimmer in this review article is about 15 pounds; the lightest is under 10 pounds. For fifteen minute projects, this amount of weight is probably not a concern. If you're using it for an hour, an extra 5 pounds can mean a lot. The best cordless trimmer is the one you and your family can use safely and comfortably.

Additionally, string trimmers don't offer a uniform length. If you're of average height, any of these will probably work. For those over 6 feet, the Craftsman is probably not the best choice. For those 5'3" and under, the Makita will be too long. If the users of this tool run the gamut from tall to short, the Worx has a telescoping handle! The best cordless weed eater is the one everyone understands and can use safely.

Consider who will be the primary user of the string trimmer and make your choice based on their capabilities. Invest in the proper safety equipment for each user, and make sure everyone is trained on safe usage. Window replacement is bothersome and expensive.

To Bump or Not to Bump?

Many string trimmers have a bump feature, or a disc on the bottom of the trimmer that you can bump on the ground to feed more line. This is in contrast to the automatic feeding mechanism.

If you've got heavy brush to clear, the automatic feeding feature may not work. Working with a long cutting line on tidy, even grass can be very effective, but if you've got tall weedy plants to try to cut away with your string trimmer, a long trimming line can make for a tangled mess. With a bumping mechanism, you can control the length of the trimming string more easily and work shorter in heavy weeds.

If you're studying cordless weed trimmer reviews to make your final selection, consider the amount of time you want to put in replacing string and maintaining this tool. String feeds can be confusing and it takes time to learn how to load the feeder. For users who need to pick up this tool and go, getting a product that offers replacement spools is probably the best option.

Get an Extra Battery

Many cordless products feature interchangeable batteries that you can move from one tool of that brand to another. Even if this is your only cordless tool for now, invest in a second battery and keep it charged while the original battery is loaded in the tool. Downtime due to dead battery is a frustrating waste.
