Blades Disengaging

[Captain Obvious]

Hey ya'll..
New to the site and having issues with my Cub Cadet RZT L 42 mower. So recently while mowing, the blades will disengage out of nowhere. Thought it might be the PTO switch, so I swapped that out, but still having the issue. Checked underneath and the belt looks fine. Any suggestions as to what the issue might be?

Did you check the connection to the PTO clutch? Unplug it, and clean the connection and see what happens. When it disengages, what happens next? Can you cycle the switch and restart the blades?

Please supply the model number and serial off the mower tag, in case anyone needs to check documentation on the mower.
