These trimmers are used for trimming branches, with a diameter of ¾ inch or more. The blade type may be reciprocating or non-reciprocating. The former has two blades working in opposite directions, which allow branch cutting smoothly, giving a clean cut surface. Non-reciprocating blade, consists of only one blade and gives a shredded appearance.
Some models have translucent fuel tanks, so that the status of the fuel can be monitored before starting the trimming process. Thus, you can make sure that fuel does not run out in the middle of the process. Whatever be the type, they should be operated properly by following basic tree trimming tips and using safety gears (gloves and protective goggles).
Pros and Cons
Compared to electric variants, gas powered trimmers offer more power for heavy trimming. These are cordless, thus useful for large gardens. For cutting branches of a large diameter, most garden enthusiasts prefer these, rather than electronic ones having low cut capacity. They can be used safely in a wet environment, which is not so for electronic type.
Based upon the size of the garden and requirements, you can select a correct gas powered hedge trimmer. While buying one, ensure that you check the diameter of the cutting head, weight, blade size, blade type, engine types, and safety of the device. For using in all hedging types, it is better to select longer blades (about 18 inch).
You can shop around and compare the different models from various brands. You can also refer to the customer reviews for getting an idea about the best brands. Buying the correct one will help you in performing the trimming task easily and quickly.
