In this post I compare some of the differences between the John Deere 420 Utility and the John Deere 430 Utility.
The 430 has an Oliver loader, but I tried to focus on the mechanical differences between the machines. The 420 and 430 were John Deere two-cylinder tractors, manufactured in Debuque, Iowa. What makes them unique over the Moline tractors is the vertical two-cylinder engine and foot clutch. The Moline tractors had a horizontal two-cylinder engine with a hand clutch (among other factory-specific differences).
