The DTC was PO428 catalyst temp sensor high bank 1. Mechanic said it was tha “back one”. That is all I know. Do you drive with a heavy foot? I try to keep RPM’s under 2000 and never Deere gen messages.

I have replaced the Carbon Level Sensor on my wife's JEEP eco which solved that code. The regen normally occurs at 2K and above rpms and normally occurs without any notification. Heavy foot does equal more soot but with sufficient highway driving regen takes care of it.
