At any one time here at @JAMSIONLINE , the shop is almost guaranteed to have at least one John Deere component in for machine work... In this video, we draw a comparison between the cylinder heads of a 4010 JD, a 3020 gas JD, an early 4020 JD, a late 4020 JD, and a 4230 JD. These are some of the earlier 4 and 6 cylinder John Deere tractor models, and probably the most common job we see here in our machine shop.
