Fastback. No, there wasn't a wiring diagram. I figured it out by tracing the wires back to insure red was power. I wouldn't classify it as a worry, but again - I've seen pretty silly things come out of China. That was where my concern was. (...and to your advice, I bought a cheap multi meter as well. The tool box needed it.
KennyV. Thanks again. You are a wealth of knowledge. (If ever in NH, I owe you a cold one.) So, if mulching blades provide lift as well, you bet, I'll try just running those. I was under the impression that the mulching kit blocked off the discharge shoot. Do you PGT9000 guys know if this is a quick disconnect type thing? Meaning can I go from bagging to mulching EXTERNALLY or do I have to pull the deck to go to mulching, (to add whatever piece?)
Someday I'll post some pictures. I'm working to make you lawn nuts proud.
