String trimmers, also known as whipper snippers or weed eaters are an essential tool in your lawn care arsenal. If you're starting a lawn care business, a commercial-grade string trimmer should be one of the first tools you buy, along with a good commercial lawn mower.

String trimmers are classified according to how they are powered. Some run on gas, some on electricity, and others on batteries.

Of all these, gas string trimmers are considered to be the most effective and powerful of them all. This is based on the fact that they can be used on lawns of any size (as compared to electric string trimmers that need power to operate) and gas lasts longer than cordless batteries.

Indeed, if you are a lawn care specialist, then you will want one of the best gas powered string trimmers your money can buy. If you want something that is going to perform under daily use you need to be looking for a gas string trimmer that is professional grade.

In compiling our list of the best gas powered strimmers we considered the following factors:

  • Dealer Support - Choosing the right brand is also important in terms of ensuring there will be adequate dealer support in your local area. The brands we've selected are widely used in the commercial sector and hence you shouldn't have any issues with dealer support.
  • Resaleability - if your a lawn care professional then resaleability should be an important factor for you when choosing a gas string trimmer. Since repair costs can add up quickly, many lawn care business owners choose to sell their lawn care equipment once the warranty has expired. 
  • Weight and handling comfort - our top picks are some of the lightest gas string trimmers on the market, with good weight distribution allowing for comfortable handling. We're also interested in other features that aid with a comfortable use such as a padded handle. 
  • Power & performance - the key factor to getting a professional cut in the least amount of time, maximizing task efficiency. We've chosen strimmers that will cut through grass like a hot knife through butter.
  • Warranty - Some of the models we've chosen come with a 2 year commercial use warranty, providing you with peace of mind. Its important to check the terms of the warranty so you know what is covered. Warranties do not cover wear items such as belts, bearings, cart wheels, filters, wheels, wear pads or spark plugs.

Safety First! A word of caution when using gas string trimmers: always use safety glasses and hearing protection. Debris can be deflected whilst using this equipment which can easily cause permanent damage to your eyes. Gas string trimmers are also usually above the safe noise limit and therefore hearing protection is required.
