Overtime innovation has done as a good deal and all we are being met with are the beautifully manicured lawns, with well-trimmed grass and hedges.

So, for as much as we would like to give all the credit to the landscapers, the innovative trimming machines are the ultimate performers. To which end there are different types and brands of the 4 stroke weed eaters, which consequently makes choosing the best a daunting task. The 4 stroke weed eater is therefore, an advanced version of the 2 stroke.

And if you therefore, haven’t had the chance to interact with the two-cycle engine then you must know that it produces a lot of exhaust and it is very noisy. The four-cycle, on the other hand, has incorporated a crankcase, is quite and comes complete with an oil distribution system that works to separate oil from gasoline, to help in the lubrication of the parts of the engine that are moving.

Tips on purchasing a 4 Stroke weed eater

Before we get down to the relevant features that you will be looking out for, you must first know that the 4 stroke weed eaters are usually highly-priced. So be prepared to put your hand deep into your pocket during purchase. Another important maintenance feature is that you will have to carry out some oil changes from time to time, but after some period of use.

Features to look out for,

  • The cutting width – each of the trimmers comes with differently inched swaths, so depending on your preference, you will either settle with a unit that covers a large area in less time or one that takes time and is, therefore, more detailed.
  • Straight Shaft- Trimmers are either feature a straight or a curved shaft, each of which suffices in different applications, for example, the straight shaft works well in areas that are hard to reach while the curved shafts will reach the corners that are hard to navigate. Users will, therefore, settle with either as regards the orientation of their lawns or yards.
  • Price- your budget plays a big role when it comes to picking a reliable trimmer. And for the 4 strokes better believe it when they say that you get what you pay for. So while a cheaply priced unit will be effective, it will miss some of the important features and functionalities. What’s more is that some of them cannot incorporate other attachments thus offer limited operational options.
  • Durability – When it comes to durability it all boils down to application, if you are getting a commercial 4 stroke weed eater ensure to go through the reviews of people who have previously owned the equipment. But for personal use, no need to worry your head, because using the trimmer will be on selected occasions and season.

Conclusions

When it comes to purchasing the 4 stroke weed eaters, it’s never about the money, but the ease of use, quietness, and versatility. Besides some of these units are detachable making them easy to store and carry around because of their lightweight. The 4-stroke trimmers are low on emissions, a feature that makes them quite adaptable because they inadvertently support the green movement.

Apart from preventing high emissions, the units are exceptionally quiet, especially when compared to the 2 strokes. So apart from leaving you with a cosmetic lawn, the weed eater will not wake your neighbors early in the weekend. Lastly, when it comes to power, weed eaters are dependent on four sources of power, and these are gas, electricity, and batteries, of the three it might interest you to know that gas is the most powerful and efficient.
