I am not a commercial mowing firm, I own a Scag 48" tiger cub, mow about 10 acres per week on our properties and I have alot of weed eating to do weekly. i dont mind paying a premium price for good commercial equipment. The wife buys some snapper weed eater i hate because every 5 minutes you have to fool with the darn line, so i go buy an Echo with the head that you use individual strings that pock in, thinking that would solve my problem, i end up every couple of feet having to put in a new piece of string. So i buy a new head that the string wraps around and comes out with a dual line. I use 095 line to 105. Either the line does not feed on one end or the other or I am having to stop and re-string the head every 5 minutes. To make a short story long I just want a weed eater that i can run and feed line and finish a job with out having to re string the darn thing every 5 minutes. Any Suggestions? I end up spending more time fiddling with the line than actually weed eating. I want a weed eater that speeds more time working and less time working on. PLEASE HELP!!!!
