Hey, I'm new here, but I recently bought a 2011 B2630 with a loader and a backhoe. I took the backhoe off, so I could use the rear PTO, but it's not working. The mid PTO turns on fine, but when I engage the rear one, I hear a click, the shaft turns a bit, then the tractor stalls. Any idea what the problem could be? I called a mechanic, and he said it could be a bearing. Is that an easy fix, or just better to send it to a shop? Thanks in advance
