I live on a corner lot which has a 140 foot long drainage ditch along one side. The banks of the ditch are sodded with St. Augustine grass. So I do not need a very powerful trimmer with a cutting wheel as the ditch is all sod. The drainage ditch is fairly step in that there is a 36" culvert under my driveway. I currently have a Stihl Kombi system with the trimmer attachment but my wife complains that it is to heavy. Does anyone make a reliable light weight string trimmer that she could use to trim the ditch. It is a lot to trim with a string trimmer, but I am recovering from foot surgery and hired a lawn service to mow my yard and they did a horrible job, burned the yard in some spots, missed other spots. As soon as I can I need to get back to doing it myself. My wife will help if I find her a LIGHT WEIGHT trimmer. Hopefully you guys have an answer. I need to keep the help happy.
