Hello, hope someone can help me out. Today, for some unknown (to me) reason, when I engaged my rear PTO to begin mowing, a fuse blew and shut down the entire tractor. I replaced the fuse and all was well. I tried to mow again. As soon as I engaged the PTO, you guessed it, the same fuse blew. Ok, so there's a problem. I'm guessing it has something to do with a "KILL SWITCH" but I have no idea where to look. I've looked under the seat, but the switch there looks to be ok, no frayed wires etc. Can anyone give me a heads up where else to look? Thanks.
