The first thing to consider when shopping for a grass trimmer is to decide how you will use it. If you have a large yard with a lot of hard-to-reach patches of grass, then you need a trimmer that can go anywhere. A corded trimmer won't work for you because you won't have plug-ins available across several acres. You need either a gas grass trimmer or an electric grass trimmer. However, if you are just looking at a few areas near your porch, distance isn't as big a consideration.
No. 2: How often will you use it?
The second thing to consider is how often you will use it. If you live in an area with plenty of rain and sunshine, the grass grows quickly enough that you'll be trimming often. That means you need to look at gas grass trimmers and electric grass trimmers with higher price tags. You get what you pay for, and if you're going to use the trimmer often, you need one that is built to last. In the end, it'll be less expensive to buy one with a higher price tag that will last for years with proper maintenance than to buy an inexpensive one every few years.
No. 3: What is the terrain like?
The third consideration is the terrain of your yard. If you live on a farm, in a rural area or have several acres to care for and will have to clear tall grass and brush periodically, you'll need a gas trimmer. With a gas trimmer, you can use larger diameter trim lines, which is what you need when chopping through thick, tall grass and brush. Electric trimmers lack the power to tackle such jobs. Using an electric trimmer instead of a gas one for tall brush is like using a handsaw instead of a chainsaw to take down a big tree.
No. 4: What obstacles do you have to trim around?
Now consider what obstacles are near the area where you need the trimmer. Will you be trimming more around flowers and vegetables or fences and bushes? If you have to trim under fences and bushes, you'll need a trimmer with a straight, long shank to extend your reach to get the job done. If you have to follow along curves near a flowerbed or garden, you'll find it's easier to maneuver and cut grass by using a trimmer with a curved shank. No matter what the job, it's important to have the right tools.
