the new style regen process is as follows on all new models 30hp and up. when you initially see the dpf regen light flashing you will
park the tractor and set the emergency brake/parking brake, rev the tractor up to 2900 rpms, then press and hold the regen switch until the second light come on the dash which will blink at you indicating the regen process has started after that you leave it to regen this process can take anywhere form 10-45 minutes depending on how full the filter is.
once the tractors data logger senses the correct temperature and pressure it will shut the lights off indicating the process is done, form there is as simple as shutting the tractor off and on again the clear the lights( sometimes the lights wont clear in which case you have the turn the key off then as you turn the key to the on position only, as soon as you turn it to on you have the rapidly press the regen switch 3-5 times and this should clear the lights and alarm)
i think i wrote this out as simply as i could if anyone has any questions message me i'll try to be more clear about it.
