Recently bought a Krone mower out of a genuine farm sale. Went to farm spoke with owner while loading and brought it home. Went to fire it up making a terrible racket. Was missing 9 conditioner tines so got them put them in as I hoped she was just unbalanced. Still running bad. Anyway teeth stripped on bed cogs is what was causing the noise. Rang farmer who maintained it was working perfectly for him. This guy is 78 and was quitting farming. I am definitely losing faith in the human race. I would have expected this at a blind collective sale but not at a farm sale. Any similar experiences?
