For my own part I don't think turbo's are bad on small engines. The can replace displacement. The biggest problem I see with these light tractors with high power to weight ratio is that there isn't enough tractor there to do any work and last any length of time. Chopping 1000 pounds of steel, or more out of a tractor's major components, and then calling it the same tractor of yesterday is a no go to me. Chopping a cylinder off and replacing it with a turbo isn't really the issue. The basic geometry and major components of the engines are largely the same as all these engines are modular today. They can build them plenty good to stand up to the turbo too. The biggest reason they don't perform as we'd like is because of how they design the torque and power curves. They can as easily screw that up on a N/A engine as a turbo engine.
The only real reason I'd want a N/A engine today is for a dedicated loader tractor that's starting and stopping all the time. It takes time to allow for warmup and cooldown to protect the turbo, and if you don't allow both, you'll be buying turbo's....
If you get into adding turbo's to natural engines, and turning up the fuel.... that's a whole different issue.
