When I turn the inner shaft the only things turning are the 1024 against the 608. They &quot;chatter&quot; the shift rail for the &quot;high - low&quot;. I think the trans is in nuetral. 

When I turn the outer shaft it turns the front half like has been suggested and it turns gears in the rear half. I'm guessing your right, something is siezed on the pto shaft. I'm planning on doing more tear down later this week.
