Is it true the newest tier 4 combines from Deere have a regen cycle you have to stop the combine and let it do a DPF burn out cycle on every 30-50 hours?

Oh, that would go over real well, where do I check the option box for that?
No.
Likely the worst thing you could do, it would be better off loaded as much as possible when filter cleaning is in progress.
