I have owned this tractor for a few years and have put about 300 hours on. It has always had a pretty noticeable knock and when cold. The knock is more pronounced when it is cold, less noticeable when warmed up. I was hoping to get opinions on if this sounds serious or if it's the nature of these engines(f2803). Could it be a bad bearing, Injector, etc? How could I go about determing the cause. Overall it runs pretty good, always starts right up, very slight haze in exhaust but nothing that's seems abnormal for an older machine. Thanks in advance for any insight.
