Deere did build a prototype in the Waterloo 4030 chassis, it had a 276ci with a turbocharger. There is a engineering photo of one with a cab and a friend has an open station with a narrow front. Fun tractor with quad range.
The 4030 is just an overgrown 2510/2520. Same engine with two more cylinders and same transmission. I think the 4030s bad rap of being underpowered comes from people expecting it to replace a 4020 since it has 6 cylinders.
