The basic chassis size of the 3020 and 4030 are the same. In other words, differential, final drives and rear axles. Hydraulics are very similar to console style 3020. Better clutch and PTO drive line like all other 30 series features. Better engine where longevity is concerned, no engine balancer and lots of replacement engines available thanks to 44/6600 combines. Excellent wide front end strength for loader use. Hope this helps.
