PowerSmart 22-inch 170cc Walk Behind String Trimmer, Gas Brush Hog Mower

The PowerSmart 22-inch 170cc Walk Behind String Trimmer is a gas-powered brush mower built for tackling overgrown outdoor areas where standard lawn mowers might struggle. Powered by a 170cc 4-cycle OHV gas engine, this machine combines the wide coverage of a push mower with the cutting action of a heavy-duty string trimmer. It is designed for property owners who need to clear thick brush, tall grass, and deep weeds across expansive or uneven terrain.

Central to its operation is the 170cc engine, which features an easy-start ignition system and an auto choke mechanism. The auto choke eliminates the need to manually choke the engine prior to starting, streamlining the startup process. Cutting performance relies on a broad 22-inch swath equipped with heavy-duty 0.155-inch trimmer line. This thick line diameter enables the cutting head to slice through dense vegetation that thinner line cannot handle, covering large lawn sections in fewer passes.

To navigate difficult landscapes, the trimmer is mounted on 14-inch wheels. These large wheels allow the unit to roll over bumpy ground, rough terrain, and unlevel surfaces while maintaining mobility. Users can adjust the cutting height between 1.90 inches and 3.90 inches depending on the height of the growth and the desired finish. Once lawn care tasks are completed, the handle folds down to minimize the footprint for storage in a garage or shed.

As a gas-powered tool, this mower requires basic engine upkeep such as checking spark plugs and managing oil and fuel. The package includes a spark plug wrench, two standard wrenches, a funnel, ten pieces of 0.155-inch line, and a user manual to assist with assembly and care. However, the listing does not specify fuel tank capacity, engine oil capacity, oil viscosity, or overall unit weight. Buyers will need to consult the included manual for exact fluid specifications before initial operation.

Verdict: The PowerSmart 170cc string trimmer is a capable choice for homeowners and land managers who need to clear dense weeds, thick brush, and tall grass over large, rough yards. Its auto-choke engine, wide 22-inch path, and large 14-inch wheels provide solid cutting capability for heavy outdoor clearing tasks.

A great fit if you:

• Have large yards or overgrown properties featuring thick weeds, deep brush, and tall grass that standard push mowers cannot manage easily.
• Need a high-capacity cutting width of 22 inches combined with heavy-duty 0.155-inch line to finish clearing projects in fewer passes.
• Traverse uneven ground or rough terrain where 14-inch wheels and an adjustable cutting height between 1.90 and 3.90 inches provide better mobility.

Consider something else if you:

• Prefer electric or battery-powered yard tools that do not involve handling gas, engine oil, or spark plug maintenance.
• Only maintain small, flat residential lawns with minimal weed growth where a conventional light trimmer or mower is sufficient.

Confirm on the listing:

• Check whether the unit comes pre-filled with engine oil or if you need to purchase 4-cycle engine oil separately before first starting it.
• Verify the recommended gas type and fuel tank capacity in the specifications to ensure you have proper fuel prepared.
• Confirm the exact overall dimensions and weight if you have limited storage space or need to transport the unit in a vehicle.
• Check the details on replacement line availability so you can easily reorder compatible 0.155-inch trimmer line when needed.

How to compare your options: When evaluating walk behind string trimmers, focus on engine displacement, wheel size, cutting width, and line thickness. A 170cc 4-cycle engine offers solid output for heavy vegetation without mixing oil and gas. If your property features rough or unlevel ground, larger 14-inch wheels offer better rollability than smaller options. Ensure the cutting height range matches your vegetation control needs before finalizing your selection.

Read the included user manual thoroughly before adding fuel or attempting to start the 170cc engine for the first time.

Use the provided funnel when adding engine fluids to keep the motor housing clean and prevent spills during routine setup.

Adjust the cutting height within its 1.90 to 3.90-inch range to suit the specific thickness and height of the weeds or brush in your working area.

Inspect the 0.155-inch trimmer line before each use and replace worn pieces using the included spare line supply and wrenches.

Fold the handle down after cleaning off debris to save space when storing the machine inside a garage or shed.
