If you read into their theory it is the best of both worlds between the four and the six ( 70-90 ) hp gap. It is a John Deere design engineered around the tier two emissions standards. For years they have relied on Yanmar for their small applications. It is looking like Deere is going back to the drawing board and design / build in their own back yard. GM has gone to the five cylinder engines in light trucks and suvs. By design it would not work well with a carburetor but with modern pressure fuel injection and counter balance shafts it hits the emissions goals.
Deere will be using them more extensively in the future.
A five cylinder engine has the fuel economy of a six with the noise and vibration of a four.
