This feature is often referred to as “split-shaft”.

Advantages of Gas Power

Gas-powered string trimmers have the advantage of mobility because they aren’t tied to a power source. They are also typically more powerful than electric trimmers, and they last longer than battery-powered options that need recharging. Modern gas-powered trimmers have made great improvements in reducing emissions and fumes.

What to Look For

Here is how to find the best gas trimmer. Your gas-powered weed eater should be lightweight and easy to handle and maneuver. Models with a protective sleeve on the cutting head will help keep tall grass and vines from getting tangled around the cutting head. Look for a centrifugal clutch, which allows the gas trimmer to idle without spinning the cutting head. A rotating head is helpful for edging without having to hold the trimmer sideways. Here are some other features to consider.

  • Shaft Shape
    • Straight shaft – offers longer reach
    • Curved shaft – easier to maneuver
  • Line Feed
    • A bump feed releases more line from a spool as you need it. This means you have to replace it less often.
    • Fixed-line head uses short lengths of line to eliminate tangling. This means that you have to thread in new line more often.
  • Engine type
    • Four cycle engines are more expensive, but they are easier to start, more powerful, and quieter.
    • Two-cycle engines are more affordable, and they should have separate primer, choke, and throttle controls for easier start-up.

Safety & Operation

Wear the proper safety gear when using your best gas string trimmers. If it is very loud, you will need hearing protection. Also recommended are safety glasses, gloves, closed-toed boots, and long pants.

Make sure to use the recommended size line for your trimmer. Know what kind of fuel and oil your trimmer requires and have extra on hand.

For the best cutting experience, keep the best gas string trimmers about 2-3 inches from the ground, and sweep side to side in a steady motion. For very tall grass and weeds, cut in sections starting at the top. This helps avoid the problem of long vegetation getting tangled in the cutting head. Near trees, rocks, and other obstacles be careful not to get too close and hit the obstacle directly with the trimmer.

When you’re done using the trimmer for the day, clean it of debris, and check the gas level and the condition of the string. Then all will be in order the next time you need it.

One thought on “Best Gas String Trimmers (2020)- Reviews & Buying Guide

  1. For this guide, we focused on rechargeable cordless trimmers with enough power to cut everything from simple lawn grass to thick overgrown weeds. Compared with gas string trimmers, cordless models are quieter, need practically no ongoing maintenance, start with the press of a button, emit no exhaust, and can “refuel” without requiring a separate run to the gas station. Over years, our testing has proved that the best cordless tools have the run time and cutting ability for everything but the most extreme clearing jobs. For all of this power and convenience, the price of a cordless string trimmer is roughly the same as a gas model’s—and even less once you factor in the long-term cost of purchasing gas and oil and the time spent on maintenance. In some extreme circumstances, only a gas tool will do—and we have a gas-powered pick for those. But those rarely apply to most people’s needs, so the rest of this section outlines our criteria for cordless string trimmers.
