Along with the size of the engine, the type of engine and the type of starter the weed eater has, also take a look at whether the weed eater has a curved shaft or a straight shaft. If you’re a taller person, you may want to opt for a straight shaft so you won’t have to bend over as much to get the job done and potentially cause a strain on your back. Shorter people would benefit more from a curved shaft since it will be much easier to hold the trimmer perpendicular to the grass for easier and more even trimming.
Take into consideration the type of weed eating you will be doing as well. Some people prefer a straight shaft if they do a lot of edging, while others like curved shafts regardless. There’s no right or wrong answer, but it all depends on your needs and the type of work you’ll be doing.
If you have the opportunity to hold and use a weed eater before purchasing it, we recommend doing so. One of the main things people overlook is the weight of the weed eater. Weed eating for an extended amount of time can put a strain on your back, arms and shoulders, so you may want to also consider whether the weed eater has a strap or other device for added support. And if you do hold one at a store, just remember it will be a little heavier when you get it home and put fuel in it.
