Thanks so much, Roland.
I understand closing the circuit with the PTO in the off position and the break engaged. Regarding the ignition switch, I'm not sure what is meant by "B & S has to be made". Is this turning the key to the first position?
Also, I had tried following the directions from your initial post to go to "the Technical Library Section and on Page 5, download the 1x8/9 Wiring Diagram", but was not able to find the post in the section
Only Cub Cadets > Resources > Technical Library - Tractors. Was I perhaps in the wrong neighborhood (or is there a URL I could follow to find the schematic you embedded in your message)? I assume there will be other useful information in this area of the site.
Thanks again for your help with this!
