What is a Gas String Trimmer
To keep the good look of the lawn in your yard, you need to take care of it opportunely, otherwise, weeds will overgrow grass and the appearance of the lawn will be poor. There are many ways to groom a lawn, yet the grass mowing is the most effective. We used bulky scythes and sickles many years ago. Now, we can use gas string trimmers. A string trimmer consists of a powerful engine rotating the spool with the monofilament line (or string) inside. String trimmers commonly refer to lawn mowers, yet they do a better work on rough surfaces and reach the places where lawn mowers fail. Moreover, string trimmers are more powerful and maneuverable thanks to gasoline engines. Such a design allows using string trimmers almost anywhere, so they will be good both for amateur gardeners and professionals.
What Features to Compare
Type of engine
When looking for a string trimmer, you need to determine the area where it will be used. Having decided on this, you should choose the type of engine. If you are going to take care of small-sized lawn, you should pay attention to the models with 2-cycle engines of low or medium power. The ease of maintenance and affordable price are the advantages of these models. Yet, you need to mix oil and gas or buy the ready mix in a specialized shop to feed 2-cycle engine. The models with 4-cycle engines will be good for large lawns, and their design allows them to endure high loads without overheating. The 4-cycle engines are more powerful than 2-cycle analogs, they vibrate less and, therefore, serve longer. Moreover, they need only gasoline that you can find at any filling station. You should also pay attention to the engine start system. In particular, you need to consider electric starters and accessories for an easy manual start. Finally, the fuel tank capacity is also very important. The bigger the fuel tank is, the longer the string trimmer works.
Design is the next point to pay attention to. You should consider several parameters that directly affect performance. Gas string trimmers with straight shaft are great for mowing the grass under bushes, benches and tables and more than other models suitable for tall people. String trimmers with a curved shaft would be easier in exploitation and more suitable for people of short/average height. Their only flaw is slight inconvenience for reaching out for the grass in confined places.
Any gas string trimmer is equipped with a spool, and the spools are different by their structure and line feed system. The models with semiautomatic string feed are the most widespread today. The semiautomatic feed system supplies the string when you bump the spool. Automatic feed systems supply the string without any outer influence. As for the manual feed system, you have to supply the string yourself by loosening the spool and pulling the string out to the needed length. The string trimmers also differ by the method of the string installation. Some models require spool disassembly and hand string winding, which takes a lot of time. Meanwhile, in other models, it is enough to pull the string through the spool and twist it several times. Hence, the installation is easy and quick. The majority of trimmers cover a 17" cutting path and hold 0.095" string diameter.
Usability of a string trimmer is the last but still important thing to consider. You should pay closer attention to the models with quick start systems. Demountable shaft will facilitate storage and transportation of a trimmer. The adjustability of the handle will let you customize its length according to your needs. The cutting head shield, trigger lock, and on/off button will significantly improve the safety of a trimmer. The accessory blades or equipment will turn your trimmer into a versatile garden assistant.
