Most of the models on our list performed well in durability tests, but we tried to point out any models that could improve.

You will want to make sure any model you are looking at uses durable materials and not thin, flimsy plastic. Your weed eater can take a lot of abuse from bumping and general use while using it in a commercial setting. Bumping is a very common way to damage the weed eater, so we recommend taking the time to learn proper technique before anything else.

The only downside to bump feed is that you can damage the head and guard if you are not careful and bump the machine too hard. Bump feed is the original time-tested method, and it allows much more control over your line than is possible with an automatic feed. These models are all bump feed, which means that you gently tap it off the ground to release more when you need it. Automatic devices are complex and difficult to repair, so we left them off our list of commercial weed eaters. There are two ways to get more line while you are working, bump feed and automatic feed. If choosing between two similar models, we recommend the one with the bigger cutting width. A wider cutting will go through more string, but the time-saving advantage makes it worth it. The cutting width that the weed eater provides can make a big difference in how long it takes you to complete a project. It’s also a bit harder to use attachments with curved shafts, and you probably see fewer of them in the field. The curved type lets you see the cutting line better, so you can make more accurate cuts, while the straight shaft allows you to get into hard to reach areas. Some shafts are straight, while others are curved. On our list, we considered everything over 10 pounds heavy, but you may be able to go a little heavier in some cases. While you will quickly build the strength required to do so, a lighter model will be much easier to work with for an extended time. You will need to carry your weed eater quite a bit when using it in a commercial setting. The one downside to a larger engine is that it will use more gas and produce more harmful greenhouse gas emissions. We tried to list the CCs of gasoline-powered models on our list, and we recommend going with the model with the larger value if you’re choosing between two. More displacement equals more power, so an engine with higher CCs will have more power. CCĬC means a cubic centimeter, and it talks about displacement in the fuel system.

Four cycles are better than 2 cycles, and they accept ordinary gasoline, where 2-cycle engines require a gas and oil mix. When choosing a gasoline-powered engine, you will usually see one statistic referring to a 2 or 4-cycle engine. Anything less may not have enough power, or it may lose power too quickly. When choosing a battery-powered model, you want to choose one that uses an 18 or 20-volt lithium-ion battery. Need to purchase battery and charger separately.
