Not that I'm just prejudiced by my Dodge Cummins, Our family farm has 5 Cummins irrigation power units:
1 855
1 505
2 359 (160hp 12V)
1 Unknown V-6 (Sounds just like a NASCAR V-8!)
Not to mention our farmer's tractors, 2
Steiger 4wd tractors w/ 855 Cummins.
Also 2 8T370? Cummins pushing a 60 foot houseboat.
Seen good and bad in these engines, but cool thing is, parts and maintainability are pretty good. Local Cat service tech loves to do sideline jobs on Cummins, can trade parts or hunting rights for services performed! Cummins is popular in irrigation units around here, but have noticed lately Isuzu moving in, Deutz (OK), Deere also trying to move in this market (Deere is pushing some of their tried and true I-6 engines). Intersting subject, I'd still trust Cummins based on my experience...
