Sometimes when I turn the key on this thing, I get nothing. I think it's the pto safety switch, but I can't find the switch! The pto lever linkage goes directly into the transmission. I've had to replace the seat switch and mid pto switch already (easy to find), and I've replaced the ignition switch and battery. In the past, I've been able to "wiggle" the pto lever to get it to start, but now I can't even count on that. The only diagram I have seems to show the switch at the bottom of the lever, before it goes into the trans. box, but it's not there. Any help????
