I started another thread that no one has replied to, so here is another try. I am contemplating taking back my brand new John Deere XT140 because the metal around the top of the shaft gets so hot. When I was trimming a bank, it got me several times. I just read a thread that some Stihls do the same thing. I had a Stihl FS55 and it never burned me. I have also used a Kawasaki and Echo extensively with no prolem with this. I would like some input from Stihl and JD owners. Please help. I talked to the dealer today and plan to take it back tomorrow. Thanks.
