Started to bush hog yesterday and when I engaged the PTO it sheared the bolt in the driveshaft. When I idled down and got off I noticed the knocking. It?s coming from right behind the engine below the steering wheel. I can feel it a very little through the clutch pedal. Clutching and driving doesn?t change the noise. Kind of disappears (or you can?t really hear it at higher rpms). It?s changed by the rear differential lock lever. Moving the lever will make the knock louder at times and there?s chatter when you try to engage (FYI I?ve never used the lock). Tractor operates fine but has the knocking.
Any help with diagnosing would be appreciated. Also if it?s safe to use as is and how to fix.
Thanks
