My 3560 was able to complete its second regen today at about 10 F. Required a higher rpm to get the symbol to stop blinking, about 2400, than when the air temp was warmer this fall. Seemed like it took a little longer about 15 min.
I think it would be nicer from a user point of view if one could initiate regen any time convenient after 90% or so. Mine has a tendency to reach 100% about when I want to put it away. The tech from my dealer told me just to wait until the next time I wanted to use it. However, the coming week is forecast to be even colder here so I didn't want to run into problems if it hit 100% just as I started it up. But finding something for it to do or just waiting for it to finish regen is a PITA if you are tired cold and hungry. Does anyone have any idea how long you can run your tractor in the different regen stages, eg light on but no beeping, beeping and light?
