Well, displacement (cubic inches) is the key to power and the more cylinders...the more power impulses per revolution of the crank. I would also tend to think if the larger engine wasn't ran against the wall.....as a smaller engine might be..it would be more efficient. Years ago, GMC had a couple big V6 truck engines....one was 305 cubes and the other 405 as I recall (if I am wrong I will very soon be corrected). Anyway, while that 305 V6 sucked gasoline, the 366 V8 was surprisingly easy in comparison. The 405 V6 was just atrocious..hehehe! They didn't last too long and the big block V8's...the 366 and 427 ruled the day.

I think you can apply this logic to your question on tractor engines.
