The TB525 EC gas string trimmer

Yotube Video Review: The TB525 EC gas string trimmer

Benefits of 4 Cycle Weed Eaters

There are lots of questions as to why most people tend to prefer the 4-cycle machines. I will try to give a clear answer by outlining the benefits that you derive from using these machines. Below are three of the most notable advantages of using 4-cycle weed trimmers:

  • Lower emissions: While trimming your lawn you need to take some consideration regarding its effect on the environment. Carbon-footprint is constantly on the rise and has contributed largely to global warming. The 4-cycle machines are equipped with an advanced technology designed to keep carbon emission at a minimum. This renders them a much healthier choice. The fact that they are CARB compliant also makes them legal for use in all states. Therefore regardless of where you live, be assured that these machines are certified for your needs.
  • Quieter: Some neighbors can be quite quarrelsome. However, they have a right to be so in case your weed eater machine proves to be a nuisance. You can avoid all these by using a 4-cycle machine. They generate lower noise level that is comfortable both to the user and those around. Some of these machines can even be used during odd hours without waking up the neighbors.
  • Easy starting: Starting a 2-cycle weed eater can be a gruesome task. But with the 4-cycle machines, the task has been made much easier. Mixing the oil and gas requires less priming. Unlike the 2-cycle machines that need constant pulling, only a single pull of the cord sets the engine running. These machines help you achieve more with just a little effort.

How to Choose the 4 cycle Weed Eater

If you desire a well-trimmed lawn that will be the envy of the neighborhood, then you have to choose the right machine for the job. But where do you start from? Well, I will outline the different factors that you need to put in mind while on the market.

  • Price

Different weed eaters come with different price tags. Therefore, it would be better to first know your range. Don’t select a weed eater machine that will weigh you down in terms of cash. Go for one that is within your budget and has the right features that will deliver as per your expectations.

  • Brand

There are many manufacturers of 4 cycle weed eating machines. However, your main aim would be to determine those who perform the best and are known to produce superior quality machines. Brands to go for include Ryobi, Troy-Bilt, and Poulan, among others.

  • Warranty

What warranty does the manufacturer provide for the product? If there isn’t any warranty then it would be best to stay away from that product. Most string trimmers come with an at least 2-year limited warranty to cover defects in materials or poor craftsmanship.

  • Customer reviews

Reading customer reviews is the simplest way to choosing the best string trimmer on the market. Get to know what customers are saying regarding a particular model. Weigh the pros and cons they give to that model and decide if it’s the best match for your needs.
