I have just taken apart my 49 cub trying to fix the Pto. It will not engauge every time or I should say most of the time. I understand that the handle throws the collar up to the drive gear. But after taking the handle,pin and collar out and meshing them together they mesh like what I would consider great. I get a grinding noise when I attempt to to the Pto in gear. What is up. Does the the shaft inside the transmission gear box come back any more or what?
Check out the pics.
Thanks to all who reply.
