ENGINES OVERVIEW
The John Deere 4230 is equipped with a robust 6.6L 6-cylinder diesel engine, providing high torque and fuel efficiency, ideal for heavy-duty applications. Alternatively, the 5.9L 6-cylinder gasoline engine offers lower operational costs but may lack the power required for intensive tasks. The choice of engine impacts performance in scenarios such as plowing versus transport; diesel excels in demanding conditions, while gasoline may be more suitable for lighter farm duties.
