Hey y'all.
I know the addage "throttle down gear up" and quite a lot of my work is low power.

What's the lowest working and long term idling these engines should do?

I don't want to starve the motor of oil or cause stress on it when I don't need to. But I do not need all 100hp and 2200rpm for things like moving equipment around the yard or making an empty trailer.

Interesting question. How often do you give it a decent workout? I don't own a 190XT, but I've raked hay for hours on end at 1000 rpm or so with many tractors. Just enough speed to where it will hold a steady speed. But then those tractors get worked or revved at other times.

Does the temp come up on these tasks? If so, I'd think you're ultimately OK. Sitting idling for long times can "wash" the cylinders which isn't good of course.

For a 190 diesel i would want to go 1500-1600 in the field. Just putting around the yard 1100+. Even when I sit and load a manure spreader quick I like to run 700-800. Other wise next you will be posting about black running down your exhaust.
