Not to take any thunder out of your post Whatsoever! but I own one of these
Amazon.com: Black & Decker 18-Volt Cordless Electric 12-Inch Grass Hog String Trimmer/Edger #NST2018: Home Improvement And have owned a reel mower in the past and Think they would make an excellent pair.
Do you think I could do 4 Acres with one?
