Wolfman-
The WSM really wasn't much help, unless I missed something. What I do know now, that I didn't previously, and it may not make a difference, but when engage the tractor clutch, the rear PTO disengages. I just can't get it to disengage with the on/off lever. When the lever is moved on/off, it appears that the cable and all connections are moving as they should. Any more suggestions on what to do next? Thank you!
