ISX15 Idling in farm operation

[CornFarmer]

I have a new-to-me 2014 W900L with a 2350 ISX15 in it, with 451,000 miles. I was able to review the complete service history before purchase, it was leased by the dealership and they had entire history in a spreadsheet. No major problems, biggest things were A/C related, and the carbon on cylinder issue at around 130k. It did have all updates and bulletins completed including the fuel tappets (if anyone is interested or willing to look at it for other red flags I'd be glad to send the excel file!).

Anyway, this week I replaced iMAP, Delta P, Exhaust back pressure sensors, put in maintenance-free crankcase filter, and new doser injector. They were all still factory. I did pull a few parts of the piping but did not appear to be terribly sooted, so I didn't pull everything off to clean - is this a mistake?

A couple of big questions for you guys, first - is the forced regen a necessary part of this process? I do have a friend who has a farm tractor repair shop and believe he has Insite software so we could probably do it over a couple beers some evening if needed. Didn't know what the benefits were of doing it if not messing with the turbo.

My biggest question regards idling time.

First let me describe my application. In the fall for 2-3 months we pull 80-90,000 out of corn/soybean fields, short hauls averaging 10-20 miles loaded to the elevator, including a river valley with a pretty big hill to pull. Then unloaded back to the field, where in soybeans (half our acres) we can wait 30-60 minutes for the next load. In corn, its pretty much nonstop - as soon as we get back the next load is ready.

I know mandated engines are not idle-friendly. My question is, what would be the maximum time you'd allow the 2350 to idle? During soybean harvest it can be pretty hot some days so the A/C is nice to have while waiting... What procedure for cool down would you use if you'd recommend shutting it down between loads? Does it make sense to shut down for 20 minutes to avoid that idle time?

Depending on your answer to this, my follow up would be regarding de-mandate in this application. I've seen Rawze mention farms in posts before as good applications to consider this. Would you recommend this for me? As of right now, since I just did (most of) the EGR tuneup, I was planning to run this fall as is, then consider it next year if that would be best.

I do plan on hauling grain for the elevators for a couple months in the off-season, not much maybe 20,000 miles a year to get a little extra income, again this would be shorter hauls of under 100 miles roundtrip, but much less idle time. But there will be times where the truck sits in the shed for extended periods of time, which I know trucks in general don't seem to like.

I'm not looking to be OTR, just want to keep it out of the shop as much as possible, first mandated rig for us.

Thanks for any thoughts or help in advance.
