Keeps on working great!
(GT-1100; Trimmers)
About 25 years ago we purchased a small ECHO trimmer (Model GT-1100) for trimming around our house. We used it to keep trimmed a walking path through a field which is about half mile long. About 10 years ago we moved from PA to South Carolina and since have used it to keep a walking trail over a mile long.
I greased the shaft once, about 15 years ago, and I can’t remember the last time I changed the spark plug, if ever.
