I use manual attach as well. I just tested it and didn't have any problems

I appreciate the reply. Could be the JD 6R I’m using but it works with other PTO implements without issue. The trigger to attach the PTO pops up and it makes the manual attachment sound but the PTO shaft doesn’t seem to physically attach and I cannot run the spreader. I figured it was something on my end but didn’t know if anyone else had run into the same issue. Again, I appreciate the reply!
