All About Lawn Edgers

Electric powered lawn edgers and gasoline powered lawn edgers give homeowners an economical way to slice small trenches along sidewalks and driveways or trim close to trees, flower beds, lampposts, etc. One of the most popular types of lawn edgers whip-cuts grass and weeds with a monofilament nylon line.

Unlike push-type lawn edgers with rubber wheels and wide reels, string lawn edgers have no wheels, guides, adjustments or blades. A strong monofilament nylon line, spinning at up to 12,000 rpm, is the cutting "blade."

The line cuts both grass and weeds, but inexpensive models are best suited for smaller areas and lighter work like grass, while heavier weeds and larger areas require a heavy-duty, more expensive lawn edger with more power.

Safety is an important point for string lawn edgers. The filament or line won't cut shoes, clothing or its own electrical cord, although the line could raise welts or break the skin.

Protective goggles or glasses should be worn because the spinning line can throw debris. Electric-powered string lawn edgers are lightweight and easy to operate. Cordless models provide even more mobility, but these are used primarily for light cutting jobs and operating time is limited. String lawn edgers allow users to cut around posts, rocks, shrubs, etc., without damaging the tool. The only wear is on the nylon line, which may need to be replaced as it frays. Some units have automatic feed systems to play out more cutting line.

The smaller electric units weigh about 3 lbs. with a 1/8- to 1/10-hp power source. The cutting diameter is approximately 7" to 10".

Heavier-duty models weigh 4 to 8 lbs. with up to a 3/4-hp motor. Cutting lines are about .06" in diameter and can cut up to a 16"-wide swath. A second adjustable assist handle is usually available to provide two-handed operation and more control. With the wider cutting radius and more powerful motors, these models can handle larger jobs more easily.

Gas-powered string lawn edgers were originally made for commercial users and owners with large acreage. These weigh about 14 to 25 lbs. and are powered by a two-cycle engine.

Lighter, scaled-down models can be used by homeowners; these models weigh about 10 to 14 lbs. and provide the operating freedom of a cordless lawn edger.

The increased capacity of gas-powered lawn edgers allows the user to dig a trench between the grass and the walk with the string. In addition, metal bush-cutting blades are available as accessories for heavier cutting. Optional accessories also include blade attachments for other lawn and garden uses.

By tilting the head of the lawn edger at about a 30 degree angle, the tip of the line provides a more efficient tool.

Safety

When using these units, be sure to pay attention to the manufacturer's safety instructions and proper operating procedures, especially for metal blade accessories. Take time to read the operator's manual before using your lawn edger the first time. Safety instructions and safety symbols offer the best defense against accident and injury.

• Before using your lawn edger, carefully examine the area to be manicured and remove any objects such as rocks, branches, debris, etc.
• Check to be sure the edger blade is firmly attached. The blade should be free to rotate without contacting the housing.
• Objects struck by the lawn edger can cause severe injuries. Keep people and pets at least 50 feet away when operating equipment.
• When operating your lawn edger, wear approved eye protection such as safety glasses, goggles, or a facemask. Do not use a lawn edger on graveled surfaces.
• If your lawn edger strikes a foreign object, stop operation, disconnect the spark plug wire, and inspect the unit for damage.
• Do not allow children to operate your lawn edger.
• Remember that for all yard and garden equipment a "safety-always attitude" is your best defense against accidents and injuries.
