blades won't engage

[weskar]

I have a Toro Z-150 zero turn with a 20hp Kohler, the engine runs fine, recently the pto/ electric clutch has been has been disengaging - engaging. I can't seem to find a wire or any loose connections. Any suggestions ?

Are the blades not engaging at all, in which case I'd be looking for a loose wire or blown fuse, or are they engaging and disengaging without you turning them on and off, in which case I'd be looking for a loose wire or insulation rubbed off a wire or a defective switch. And I'm no mechanic; that's just my best guess.

You could also check the gap on the eletric clutch with a feelers guage which came with some mowers .Do you have the manuals for it
