Wheeled String Trimmer Buyer’s Guide

Need more than trimmer reviews?  No problem! Here are some of the common terms to know as they pertain to these string-trimmer-mower machines, and what you should think about when purchasing a walk behind trimmer.

Cutting Swath

The cutting swatch refers to the diameter that the walk-behind trimmer will cut.  Think of it the same as a push mower (after all, a walk behind trimmer is basically a string mower).  Most walk-behind eaters have a cutting swath of 22 inches, which is significantly larger than your average hand held trimmer.  However, there are some wheeled trimmers with a 17 inch cutting swatch. The cutting line on a walk behind trimmer reaches across the bottom of the tool so that it can remove brush and greenery in a large area at one time. Think of how the blade on a lawnmower works to get an idea about how the string works on this type of trimmer.

The Wheels

Walk behinds usually have large tires to make it easy to push through thick greenery and rough terrain. On average, the wheels range from 12 to 16 inches in diameter. This size range makes it easier for you to maneuver on surfaces that are uneven. The rougher the terrain, the bigger the tires you want to have on your trimmer. This will ensure that you can pull it through with less effort. The wheels on these tools are usually a never-flat type or a hardened plastic. No need to worry about rocks or other sharp debris puncturing your tires.

Engine Options

These trimmers come with a 2-cycle engine or a 4-cycle engine, usually the latter (and I almost always prefer four-stroke engines on weed eaters). A 4-cycle engine is always going to be more efficient, cleaner, and less noisy than a  2-cycle engine. As is the case with any gas-powered tool, make sure you perform proper maintenance and store the tool properly.  Do not forget to change the oil every 30 uses or so. Less common on these types of tool is the 2 stroke engine, which is lighter in weight, but they are usually louder and use more fuel compared to a 4-cycle engine.  Since these have wheels, weight is less of a concern than power and reliability, so go with a 4 stroke.

Starting the Trimmer

A recoil starter is the most common type of starter on this type of tool. You will pull the rope to start the engine. When you pull the rope, it forces the engine to turn over so that it will start running. This is similar to the pull-starts that you see on lawnmowers.  There are a few that have an electric start, but generally speaking that isn’t worth it.  

Replacing the Line

The owner’s manual for your trimmer will have the specifications you need to look for when you are buying replacement string for your trimmer. It is imperative that you follow these specifications to ensure that the string fits and that it provides optimal efficiency when you are using the trimmer. Here’s a great video showing how to replace string trimmer line.

You can choose different lengths, diameters, and shapes for the string that you use. The best type depends on the rigor of the job. For example, if you are performing a tough job, you want to have a thicker string. For more info, see our top picks for string trimmer line.

Walk Behind Trimmer vs Hand Held String Trimmers

Do you need a walk-behind or a hand held?  Well, for a lawn nut like me, the answer is simple: both.  But for most people, a hand-held trimmer is a necessity, whereas a walk-behind is a luxury.  Hand Held Trimmers A hand-held trimmer is going to have far more maneuverability and versatility.  You can rotate the trimmer head all three dimensions, which is handy if you have nooks and crannies or uneven terrain that you need to cut.   Hand held strimmers can also double as an edger (though a pole edger is always preferred).  Typically the cutting width is going to be smaller, and because you need to carry them, hand-held trimmers are going to be harder to use no matter how ergonomic they are.   Additionally, some hand-held gas string trimmers have attachments that can turn it into a blower, vacuum, or pole saw. Walk-behind Trimmers A walk-behind trimmer cuts horizontally and is on wheels.  Because they are mounted on ball bearing wheels, they have more powerful motors and larger cutting swath.  The enhanced power makes them ideal for tackling tall grass, thick brush, and tough weeds. Using one is sort of like mowing the lawn with a push mower.   Walk behind string trimmers are best for highly predictable edges that you have to do every weekend such as trimming around the house or fence lines.  For example, I live on a corner lot with a sidewalk and have a lot of house to trim around, and my walk behind takes me maybe 20 minutes max, whereas a  hand held would take north of an hour.

Conclusion

Though it’s not an essential yard tool like a push mower or hand-held trimmer, a walk behind string trimmer can help you tackle overgrowth and make cutting routine, even areas much less painful.  I hope that you buy a string trimmer and love it as much as I do.
