The string trimmer is very useful for cutting grass where a lawn mower has trouble maneuvering such as under bushes and next to walls. It is also well equipped to handle a bank or steep incline. There are two basic styles of string trimmers to choose from, a straight shaft or a curved shaft, as well as either gas powered or electric.
The cutting angle of a straight shaft can be adjusted to the preference of the user to eliminate or greatly reduce the need to bend over thus reducing back strain. A curved shaft has a unique function in that the holding position can be rotated 180 degrees providing a vertical cutting plane. This is very useful in cutting an edge next to a paver brick or flower bed.
A gas powered string trimmer is more mobile than an electric but is also heavier. A gas powered is better equipped to handle a large yard and an electric is more convenient for a smaller lot. An extension cord is needed for an electric that is long enough to reach all areas where the trimmer will be used and may be more suited for an elderly person.
Some string trimmers are designed so that attachments can be installed. Attachments can include a tiller for light soil tilling, a steel blade for cutting bushes or small trees and a chain saw for cutting branches that may be out of reach. Attachments are usually sold separately.
An edger is a specialized tool that is primarily designed for a single function and the is to cut an edge. It generally has a steel blade and is ideal for providing a professional look next to a driveway or curb. An edger will provide a crisp edge without creating bare spots. The blade will also slice the grass roots providing a distinct separation between the lawn and the driveway or curb.
I have found it convenient to own both a string trimmer and an edger. I like the various functions that a string trimmer provides while I also like the crisp look that an edger provides next to the driveway. Both tools help to make yard maintenance easier and quicker. Remember to always wear safety glasses when operating any power equipment.
While a lawn mower may be great for mowing the grass there is more than grass cutting to maintain a well kept lawn. A lawn mower cannot do it all and a home owner will need additional equipment to maintain a well kept lawn.
