Well, update time: I went out to the garage last night to put new skid shoes on my blade and decided to take a look at the 682. I checked to make sure the PTO 12v wire was connected, started it, and violla! PTO worked, and worked, and worked. Left it run for about 35 minutes and kept flipping that switch; worked every stinking time. I even turned it off and was able to flip the switch and hear the "click" several times. I'm going to be so angry if that was it

Not really, I'd be glad if it was something so simple, but time will tell. Now to mount the blower back up to it. I'll update if anything changes but I've got a weird feeling it's not going to be that easy
