About Weed Wacker
A string trimmer, also called a “weed-whip”, “whipper-snipper”, “weed-whacker”, a “weed eater”, a “line trimmer” (in Australia) or a “strimmer” (in the UK and Ireland), is a tool which uses a flexible monofilament line instead of a blade for cutting grass and other plants near objects, or on steep or irregular terrain. It consists of a cutting head at the end of a long shaft with a handle or handles and sometimes a shoulder strap.
A string trimmer works on the principle that a line that is turned fast enough is held out from its housing (the rotating reel) very stiffly by centrifugal force. The faster it turns the stiffer the line. Even round-section nylon line is able to cut grass and slight, woody plants quite well. Some monofilament lines designed for more powerful cutters have an extruded shape, like a star, that helps the line slash the material being cut; the line is thus able to cut quite large woody plants (small shrubs) or at least ring-bark them very effectively. These lines make disks less necessary for tough jobs.
The line is hand-wound onto a reel before the job is started, leaving both ends extending from the reel housing. The motor turns the reel and the line extends horizontally while the operator swings the trimmer about where the plants are to be trimmed. The operator controls the height at which cutting takes place and can trim down to ground level quite easily.
As the line is worn, or breaks off, the operator knocks the reel on the ground so that a release mechanism allows some of the line in the reel to extend and replace the spent portion. The newer models have an ‘auto-feed’ operation where a small cutter on the line-guard ensures that the line length exposed for cutting does not exceed the length that can be swung efficiently by the motor. Newly extended line operates more efficiently because of its heavier weight and surface effects. The speed of the spinning hub is usually controlled by a trigger on the handle.
For vertical cutting the whole machine can be tilted or some trimmers allow the head to be adjusted at different angles. Vertical cutting is not recommended near sidewalks or other concrete and pavement edges, because it leaves open grooves that allow water to collect and cause damage.
String trimmers powered by an internal combustion engine have the engine on the opposite end of the shaft from the cutting head, while electric string trimmers typically have an electric motor in the cutting head, but some other arrangements exist too. One of such is an arrangement where the trimmer is connected to heavy machinery and is powered using a hydraulic motor.

The head contains a safety shield on the user side and a rotating hub which may also be called a head or spool. Disadvantages of a gasoline-powered string trimmer include its greater weight and the significant vibration that carries throughout the device, both of which interfere with its maneuverability and contribute to muscle fatigue, as well as the requirement that motor oil be added to its fuel (if it is equipped with a two-stroke engine). Advantages of gasoline-powered trimmers include mobility (because they are not attached to a power outlet) and the higher maximum power.
Large trimmers, used for cutting roadside grass in large areas, are often heavy enough to require two hands to operate, and some are even fitted with a harness enabling the user’s torso to bear some of their weight. These very large trimmers are often referred to as brush cutters. Brush-cutter types are usually made so that a metal blade can be attached instead of the “string” (or monofilament). A metal blade enables cutting heavier woody brush.
Trimmers that have nylon or metal blades usually require straight driveshafts to handle the higher torque required to turn the heavier disk, and because of the shock loads that are passed back from the blade to the drive shaft and its gearbox(es). Smaller line trimmers have curved driveshafts to make holding the cutting-head at ground level much easier and with less strain on the operator.
Weed Wacker Buying Guide
There are several different options on weed wackers now days and they are called by a number of different names. String trimmer, line trimmer, and weed eater are just a few. If you are in the market for any of these trimming devices please pay attention as I am about to point out some of the major features.
Depending on how large your yard is and what types of weeds you will be cutting down you can choose between a gas and electric weed wacker. Electric weed eaters are often times cordless and run off of a battery. You will need to keep charge and use time in mind when buying an electric cordless weed eater. A good battery and charging system should allow you at least 30 minutes of trimming time. Keep in mind that in use time will go down after the battery has been charged several times over. Electric weed eaters are generally used to small areas of grass and do not have the power to take on thick weeds or brush. On the up side electric grass trimmers are light weight and easy to handle. Electric weed trimmers are also extremely quiet for those living in a small subdivision.
Gas weed wackers come in two types of engines ranging in sizes measured in ccs. Commercial weed trimmers run in the 30cc range and can be 2 or 4 stroke engines. 2 stroke weed eater engines will need a mix of gas and fuel. This means you will have to premix your gasoline with oil in a predesignated gas can before fueling your gas powered weed wacker. If you have a commercial engine which is 4 stroke you need to add gasoline and oil separately. Gas powered string trimmers in the 20cc engine size range are perfect for homeowners with larger property area. Most customers report their gas weed wacker running for more than two hours on a single tank.
Before making your final decision on any weed eater or weed wacker you should always take a look at the available attachments for your unit. This can increase the value of your new yard tool even more. Common weed wacker attachments include edging and hedge trimming attachments. Some companies such as Husquvarna have created a while line of attachments meant to be used with their string trimmer motor. Be sure to read up on reviews to insure choosing a good brand and model that will last you for years to come.
