Features & Specs - Green Works 21142
Weight (lbs.) Weight is rounded to the nearest tenth of a pound and doesn't include fuel, which can add 1/2 pound.
Engine size Engine cubic centimeters (cc), motor amperes (amp), and motor electrical voltage (volt) are from the manufacturer.
Shaft The shaft transfers power from the engine or motor to the lines that do the cutting. Models with straight shafts offer longer reach, while those with curved shafts tend to be lighter and easier to handle.
Four-cycle engine Uses straight gasoline and doesn't require an oil/gasoline mixture, as do the two-cycle engines found in most trimmers.
Dual line Trimmers with two lines cut more quickly and can handle heavier growth than those with just one line, since they do twice the work with each pass.
Based on the CR rrating I purchased this unit but regret my decision mostly because the unit weighs a lot (over 13 lbs and not 9.7 as stated in CR) and is too long to handle comfortably. I had to buy a shoulder belt before I could use this unit. The switch to turn the unit on will take time to get used to. The manuals are absolutely terrible and someone buying first weed trimmer will have difficulty getting started. Nowhere do the manuals show how to feed the line or how to change from weeding to edging position. Also, the trimmer is very powerful and kicks up lot of dirt and rocks and user will be well advised to wear safety goggles.

Easy to Handle
Motor Came Lose
I liked the trimmer until the motor began to separate from the housing after about 1 1/2 years of use. My usage is light duty, just edging a very small yard. The unit is no longer usable.
