In the middle of mowing a couple of nights ago, the deck shut off on me and now I get nothing when I pull up the PTO switch. I tested the switch with a voltmeter and it seems to be fine. The clutch was replaced a couple of years ago. All connections are clean. The fuse under the seat is brand new. Battery has 12.7 volts. The mower starts and runs normal but like I said, nothing happens when I pull up the PTO switch. Any ideas?
