I too have an M7060. The way my dealer explained it is while working if the regen idiot light comes on along with the raise RPM light just bump up the RPM until the raise rpm light goes out. Keep it up until the regen light goes out. If you need a parked regen you can’t use the machine for that few minutes. That’s the whole park it and put the throttle on low n hit the parked regen button. I was told the tractor won’t allow a true parked regen until it needs it. In all honesty the more I look into this topic the cloudier it seems to get.

Lots of info here, especially for the emission newbies, I agree with you on the parked regen, it is initiated by the computer, i dont think you can do a parked regen anytime you want, so. parking brake on, hst in neutral, rpms at 1000, and the computer will take over, just had my first parked regen, in 5 yrs and 700 hrs, it took 3 times to complete the task but it did. I have an hour glass on my lcd dash, i think it is for the % to regen, but hour glass is always empty.

It took 3 times ? Did you have to do anything? Or you just let it sit? How would I know how many times it took to regen? Like I said before the more I discuss this the more questions I have. So far i just see the bump up the rpm light , bump up the rpm, and a few minutes later it’s done.

Initially i set idle at 1000 for parked regen,,after a few minutes it auto throttled up, regen started, after a couple minutes it returned to idle, it did this 2 more times before it finally did a full regen, 20 minutes or so. I never touched anything during this process, if your OPERATING the tractor and regen light comes on, throttle up and keep doing what your doing, if you choose to stop and park while it is doing its thing, this is not a parked regen. I beleive the computer senses diff parimitters and decides it needs to do a full hot burn off of the def filter, From what ive read and experienced on the one parked regen was lots of white smoke, and it gets real hot, I always stay close when its parked and doing a regen. they get real hot. I have never heard of a regen only taking a cpl minutes, my 3350 takes 15-25;minutes, if you have a bigger tractor it may generate more heat and maybe faster regens, If you get the parked regen light flashing, set rpm at 1000 rpm, put in neutral, parking brake on, the computer looks for those 3 signals, if not found it will abort, do that 2 or 3 times and it will shut down requiring a service call.

My M7 and L6060 both have parked regen switches and % DPF filled meters. My SVL75-2 only has a regen inhibit switch - all regens automatic, no meter indicating DPF status so they come as a surprise, may require increasing throttle if an indicator is flashing, and is short, possibly 10 minutes although book says expect 15 to 20 minutes. I have somewhere around 2400 hours between the 3 and have never done a parked regen. My nephew has a M110GX on which he has put 3200 hours and also has never done a parked regen. But all of ours are working farm tools so they rarely run low engine speeds.

May be different for different model tractors. Only had to do one parked regen with my M7060 - and only because the regen light came on as I was backing into the barn to shut it down for the day. All I did was bump the rpm up to ~ 2000 and walk away to do some other chores. When I came back ~ 20 minutes later the regen was done so I shut the tractor down.

You'll really appreciate those fuel sucking regens when diesel is 8 bucks a gallon.

Mine have regenned when working and I keep my throttle lever at the 540 mark on tach so doesn't take any more fuel for me and all my Kubotas use about one gallon per hour so a 30 min regen would use a half a gallon or about $1.25 now but as I said before I always work mine while it regens so no extra fuel used.

Have no clue what either of mine consume, when they get down to 1/4 on the gauge, I take them to the bulk tank and fill them up. I use about 750 gallons every year, give ir take but I never keep track of it anyway. Gets delivered, goes in the bulk yank, I pump it out, burn it and replace it as needed. Part of the faming business. and of course the fuel is an operating expense and I write the cost off anyway.
