6 Best Walk Behind String Trimmers 2025 in the United States

The BILT HARD Walk Behind String Trimmer features a powerful 170cc 4-cycle OHV engine, offering ample cutting power for heavy mowing tasks. With a 22-inch cutting width, it covers a wide area, making it efficient for larger yards or farms. The trimmer uses a heavy-duty nylon line that is effective in clearing thick grass and weeds, ideal for maintaining overgrown areas.

The 14-inch never-flat wheels ensure easy maneuvering across different terrains, and the foldable ergonomic handle improves grip and storage convenience. However, the manual recoil starting mechanism might be less convenient for some users compared to automatic or electric start options. Weighing 54.1 pounds, it is relatively heavy, which might be a drawback for some users when pushing it around. The adjustable handle is a significant plus, offering customization for user comfort.

Assembly is required, which could be a disadvantage for those who prefer a ready-to-use product. This string trimmer is gasoline-powered, providing strong performance but also requiring regular maintenance and handling precautions. The product's robust design, including a one-piece steel deck, ensures durability and stability, although it may contribute to the weight. Its ability to reach tight spaces and tackle tough brush makes this trimmer well-suited for users with challenging landscaping needs.

The Earthquake Walk Behind String Mower is a gas-powered trimmer designed to tackle heavy brush and thick weeds where regular push mowers struggle. Its 160cc Viper 4-cycle engine provides solid power, making it effective for rough yard conditions. The 22-inch cutting width is wide enough to cover ground quickly, and the 14-inch never-go-flat wheels help it move smoothly over uneven terrain without the hassle of flat tires. Weighing 70 pounds, it’s fairly heavy but stable, which might feel a bit bulky for smaller users or tight spaces. The adjustable handlebar with five height positions allows for comfortable use for different users and tasks.

Starting the mower is straightforward thanks to the hand bail system that keeps the engine running safely and stops the cutting head when needed, reducing the need to restart frequently. The steel deck adds durability and lowers vibration, which can make longer jobs less tiring. Assembly is simple, mostly involving unfolding and tightening knobs, so it’s ready to run quickly out of the box.

Its weight and size mean it’s more suited for medium to large yards with tough vegetation rather than precise trimming near delicate plants or small gardens. Some users might find it less maneuverable compared to lighter models. If you need a reliable, powerful trimmer that handles challenging brush with minimal maintenance, this mower is a good choice. The included 5-year warranty adds peace of mind for long-term use.

The Powerhorse High-Wheeled Walk-Behind String Trimmer comes with a solid 173cc gas engine that provides reliable power and a 22-inch cutting width, which is wide enough for trimming larger lawn areas efficiently. Its rear wheels make it easier to maneuver compared to handheld trimmers, lending better control and reducing user fatigue during longer use. Weighing 77.5 pounds, it is on the heavier side, so it might require some effort to push, especially on uneven terrain, but this weight also adds stability during operation.

The trimmer uses a recoil (manual) start, which is simple but may take a bit of muscle to get going, particularly for users not used to pull-start engines. The offset head design is helpful for reaching edging spots. This model is suited for homeowners with medium to large yards who want a walk-behind trimmer that covers ground quickly and offers more control than handheld options. However, it is not available for sale in California, which might limit access for some buyers.

If you’re looking for a gas-powered trimmer with decent power and cutting width that is easier to steer due to its wheels, this is a practical choice. Buyers should be aware of the heavier weight and manual start method when considering this model.
