I feel that the less stress applied to a reciprocating mechanism the longer it will last. A 3 cylinder W/turbo is far from a bad choice, but it will be more highly loaded (and worked farther into that range by you) than the naturally aspirated engine.

Efficiency (raw thermal/mechanical effectiveness per unit fuel) probably favors the 3 cylinder by a few %. But it is difficult (impossible) to get those lab statistics as applied to those tractors. I hope I have not made the decision harder. JimN
