That's a lot of horsepower per unit displacement for the Deutz. When you compare that to the Deere, are you comparing a normally aspirated Deere to turboecharged Deutz? Not a fair comparison if you are. The turboed engine had much heavier internal parts and probably a heavier block casting (depending on the tractor structural arrangement), more piston crown cooling and probably a large oil quanity to use as a heat sink for cooling the piston crown as well as more cooling and a hevier transmission to take the larger horsepower, etc, etc etc. The internal loads and temperatures are much higher in a T/C engine and the fuel flow is much higher (got a lot of horses, they eat a lot of oats!). Where did you get the life numbers ("....10,000 hrs + wrench free").Is this the manufacturer's claim? Generally T/C engines require more maintenance and the parts are more expensive. I'm not saying the the Deutz or the Deere are not a good engines, I just think the comparison might not be apples to apples.
