Cord-less Weed Wacker - If You Are Looking At Buying One Look At This First

Okay, the cordless tool revolution has extended into tool categories that were not thought possible just a couple of decades ago. Is it really feasible to bore large diameter holes through framing lumber or trim heavy weeds and brush with a cordless tool? Well there are no simple answers. If the appropriate tool is acquired for the task at hand, then a cordless tool can be every bit as effective as a corded tool. However, there are some factors that should first be considered before a purchase is made.

Cordless weed wackers, otherwise known as weed trimmers, lawn trimmers, weed eaters and string trimmers come in a variety of designs. Before shopping for a trimmer, you should think about the primary purpose that the trimmer will be employed to perform. Purchasing a high powered weed and brush trimmer for light duty lawn and edge trimming is just as disastrous as acquiring a light duty trimmer and expecting it to clear thick weeds and brush.

Generally the physically heavier units tend run on higher voltage batteries and are built for jobs requiring higher power levels. The lowest voltage trimmers come with 12-volt batteries while the heavy duty units will be powered with 24 and even 36-volt batteries. Of course all other things being equal, the higher voltage batteries will be heavier. Another determining factor in the weight of the battery is the amp-hour rating of the battery. The higher this number the longer the run time will be for a single charge. So the power required for the anticipated job as well as the necessary run time to complete that same job will be important factors in making a final decision.

Once you decide what the primary function of the cordless weed wacker will be, the second step is to estimate the required length of time the trimmer will need to be active on a single charged battery. Actual user's experiences can be quiet different than the specifications indicate, so it is best to be conservative in your estimates. Nothing is worse than having a battery go dead with 25% of the project left to complete. Of course if the trimmer comes with a second battery, this problem is largely solved as long as you remember to keep the batteries charged.

Weight and balance play an important role in determining the fatigue factor in actual use. Just a few extra ounces of weight at the end of a trimmer that is poorly balanced can cause a surprising degree of muscle fatigue. If your primary need is for a lawn trimmer to cut around trees and foundations as well as an edger next to sidewalks, there are some excellent models made specifically for this purpose. They incorporate two modes of operation; a wheel-guided mode for edging and hand guided for general trimming.
