Routine gardening maintenance, like mowing and edging, is repeated often during the growing season and can become mundane. For these tasks, reliable tools save time and get the job with better efficiency. I'd rather spend my time planting and creating than mowing and edging the lawn.
I discovered a long time ago that a walk-behind edger provides the cleanest edge. I've owned several of them over the years, each made by various manufacturers.

As a member of the Troy-Bilt Saturday6 Team, they provide me with Troy-Bilt equipment of my choice each year. I get to keep it. I also test and review it. Sweet! One of the products I chose this year is the Troy-Bilt Triple Blade Lawn Edger TB554.
I wanted this edger because it had all the features I look for in a walk-behind edger:
•Self-sharpening, heavy duty 9" triple-edge blade
•6-position edging depth up to 2 1/4"
•3-position adjustable bevel for easy edging along walks and flower beds
•Curb wheel included
•Premium 7" front and 8" rear steel ball-bearing wheels
•158cc/5.0 ft-lbs* gross torque Briggs & Stratton 500 Series engine
•*ft-lbs gross torque per SAE J1940 as rated by engine manufacturer @ 3060 rpm
•2-year limited warranty
Additional features I especially appreciate about this edger:
•Easy start: the pull start is easy enough for me to pull and it cranks the motor with the first or second pull.
•Manageability: It is lightweight and easily maneuvers through the grass.
•No tilt: It has excellent balance when going around curving borders.
•Reliability: this edger contributes to efficiency in the garden and saves me time.
It is also particularly useful for shaping the circular ground cover of Asiatic jasmine (Trachelospermum asiaticum) in the back garden.
I love the triple-edge blade! It is sharp, powerful and precise.
I don't need the feature for changing the angle of the blade for my sandy soil and St. Augustine grass, but it could be beneficial for clay soils.
In the front garden, the edger shears off the Asiatic jasmine (Trachelospermum asiaticum) ground cover and keeps it from growing over the drive way.
I highly recommend this edger**. It has been a great complement to my Troy-Bilt lawn mower for keeping what's left of the lawn in the back garden tidy.
What tool do you use to keep your lawn from spreading in to the planting beds?
