09 Cub Cadet PTO disengage

[JRD1054Cub]

Afternoon.
I have a 2009 Cub SLTX 1054.
Today, while mowing, the PTO decided to disengage on me. Not quite sure what the issue could be. The battery is new.
Belts are in good shape. All wiring is solid (that I can see). Maybe a fuse?
I know Cubs are notorious for PTO problems. Any suggestions on what to check and look for would be appreciated!

I replaced the trans last year. Is it recommended to replace the eclutch as well?

back by the right rear tire is the reverse cut out switch. the wire hooked to has a habit of breaking off. on bumps the bare end hits metal and cuts the pto off.
