Jerry, I've seen low batteries cause that issue as well, I'm surprised they didn't hydro-lock the Cummins. Way back when I 19 - 20 years old I worked for a guy plowing in field tile, we had a D9 Cat - no blade, set up with laser controlled plow. 2 cylinder gas pony motor. 1473 cubic inches of 6 cylinder raw Caterpiller power, a can of either in each hand for the twin air intakes.
