As I break-in the JD5055d, I am very mindful of wet stacking and engine temps. In generator applications, I've seen built-in resistive heater load banks that put around a 30 percent load on the engine when there is no or low electrical load present. As the electrical demand increases, the load banks are shed - freeing the full hp potential of the engine as the increased load prevents wet stacking.
One thing is for sure, if the generator's diesel's engine is not loaded, it will wet stack - but this typically at 1,800 constant rpms.
What about a diesel tractor? There must be a ton of hours that the diesel engine sees little to no load and unlike a generator, no load banks to deal with wet stacking.
Haven't encountered wet stacking with my 5055d as I make it a point to keep the engine loaded to some extent during the break-in AND up to temperature, but my MF 50 will start giving a bit of blue smoke with very strong diesel vapors if it idles for an extended period, like when I'm attaching an implement. Once in gear, implement attached, there no visible sign of wet stacking. It seems that just having the tractor up to temperature and making it move itself around are enough.
But I read about and see some of the larger IH tractors or a JD 4020 that are being used with some lightweight chores, i.e. pulling a wagon, haybine (with sickle vs disc) or a small baler. These tractors look like over kill for the implement attached. Is wet stacking a problem for these larger tractors?
Anyone deal with wet stacking on their small or large hp diesel tractors? If so, how you prevent it?

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK). There is no known history regarding its origins or what service it had done, but the following work was undertaken alone to bring it up to show standard. From the engine number, it was found that this Major was produced late 1946. It was almost complete but had various parts that would definitely need replacing.
