What our shop has seen on the 200D's and 300's is the bearing seizes up in the pocket of the bracket. If your machine is going to have this problem you will hear an irritating whine for several hours before it seizes. We have also seen a lot of problems withthese machines and the Kubota engine 'surging up and down'. We have worked with the Kubota on fixing the problem. It is either on the the following:
-faulty ground connection on the engine end at any of the 3 ground connections
-improper motor oil being used and gumming up the solenoids.
