I have a 52" Surfer w/ 22hp Kohler with only about 400 hours on it. Yesterday I was going along and noticed an unfamiliar noise coming from under the deck. Upon inspecting closer (had to use gloves to pull the deck cover off it was so HOT) I found that my inside (trim side) pulley had stripped its teeth I think because the last time I sharpened the blades I caught the thread wrong on the blade bolt slightly stripping it at the top of the bolt but enough to cause the bolt not to be in quite right. Anyway I am replacing the pulley, blade bolt, and nut but was wondering why it is so damn HOT underneath my deck? This seems to be fairly common for my mower but especailly when cutting thick stuff. I asked my dealer and he said you aren't supposed to grease anything under there but I thought maybe some grease might help between the pulley and where it rests on top of the spindle housing. Suggestions?
