I've got $250.00 to spend for a back-up trimmer, what would ya'll recommend? My main trimmer is a Stihl FS90, but I am open to any brand and all suggestions. I am also seriously thinking about a new ZTR mower. I'm doing around 15 or so yards a week as a part time job. Some accounts have chain link fences in the back yard, gate sizes vary from 44" to 50". With the number of cuts per week and gate size restriction I am facing what would your recommendations be?
