If you grew up with weekly chores that consisted of cutting grass and whacking weeds, the most likely tool that you used was a 2-cycle weed eater.
To work optimally, this trimmer requires mixing of gas and oil. But if you’ve shopped in your local stores or browsed online recently, then you may have a come across a new technology that is making waves in the industry, that of the 4-stroke string trimmer.
So, why are people preferring the 4-stroke weed eater to the traditional 2-stroke model? This article tries to answer this question. It also recommends the best 4-stroke string trimmers in 2018.
Why Buy a 4-Stroke Weed Eater?
Also known as a weed wacker and a weed trimmer, a 4-cycle weed eater is better than the 2-stroke model in several ways:
- Operates more quietly – wouldn’t it be nice if you could get an early start of tending lawn without waking your neighbors up? This is what the 4-stroke weed eater offers: a powerful performance with less noisy operation.
- Convenience – since the 4-stroke weed eater runs on either diesel or gasoline, it saves you from having to keep a separate can of gas for your mower in addition to the oil container. Another way in which this string trimmer is convenient is the fact that it’s easier to start. Most of these tools have Smart Start technology that makes them easy to start.
- Lower emissions – producing fewer exhaust fumes is not just a luxury of a weed eater, but it’s quickly becoming a law in many states. In some areas, every tool must be CARB compliant.
