Something about mowers. I'm working on a Toro zero turn that won't start. Found a wiring diagram and went through the start circuit. Ignition switch was hosed up so ordered a new switch. No go. Soooo, started going through the rest of the start circuit, the PTO switch was shot as were both park interlock switches. I'm thinking, this can't be, multiple failures? But yes Virginia, all of the components were defective. Then I talk to the owner and he tells me it had blown a fuse just before it wouldn't start.....uh oh......I'm thinking the problem is still there. The new switches are supposed to arrive today, we'll see.
